1142 subprogram body that acts as its own spec may not have a non-private
1143 WITH clause on a private sibling.
1144 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
1145 child unit is a renaming, create an implicit with_clause on that
1146 parent, and not on the unit it renames, to prevent visibility errors

1249 and those of the target interface primitive.
1250 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
1251 Timed_Entry_Call): Analyze the triggering statement as the first step of
1252 the processing. If this is a dispatching select, postpone the analysis
1253 of all select statements until the Expander transforms the select. This

1255 replicated some of the select statements. In case the Expander is
1256 disabled, perform regular analysis.
1257 (Check_Triggering_Statement): New routine.
1258 (Analyze_Requeue): Exclude any interpretations that are not entries when
1259 checking overloaded names in a requeue. Also test type conformance for

1873 additional management on these nodes in Expand_Interface_Actuals.
1875 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
1876 that handles use of 'Access and 'Unchecked_Access applied to

1922 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info

1969 association for an access component, add an association with null as
1970 the expression. Remove testing for array subtypes and the setting in

1972 inclusion of an association for null-initialized arrays. Collapse
1973 condition that tests for array subtypes into just a test of
1974 Is_Partially_Initialized_Type (which already covers arrays anyway).

1991 * sem_ch4.adb: Minor code and comment reformatting.
1992 (Analyze_Allocator): When the designated type of an unconstrained

2122 files instead of units to gigi.
2123 * gigi.h (struct File_Info_Type): New.
2124 (gigi): Rename and change type of number_units parameter, change
2125 type of file_info_ptr parameter.
2126 * trans.c (number_files): New global variable.
2127 (gigi): Rename and change type of number_units parameter, change
2128 type of file_info_ptr parameter.
2129 If mapped location support is enabled, create the isomorphic mapping
2130 between source files and line maps.
2131 (Sloc_to_locus): If mapped location support is enabled, translate
2132 source location into mapped location.
2133 (annotate_with_node): Rename into set_expr_location_from_node.

2159 * a-calend-vms.adb, a-calend.adb:
2160 Add a section on leap seconds control along with two entities used to
2161 enable and disable leap seconds support. The array Leap_Second_Times is
2162 now constant and contains hard time values pre-generated. Remove
2163 all elaboration code used to populate the table of leap seconds.
2166 Add entity Leap_Seconds_Support to the list of global run-time variables
2167 along with a comment on its usage and values.
2168 (Gen_Adainit_Ada): Add code to generate the declaration and import of
2169 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
2170 or one (enabled) depending on the presence of binder switch "-y".
2171 (Gen_Adainit_C): Add code to generate the declaration of external int
2172 __gl_leap_seconds_support. Set is value to zero (disabled) or one

2182 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
2183 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
2185 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
2187 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
2188 function which can be called by the debugger to interrupt the tasks of
2189 an Ada application asynchronously, as needed on VxWorks.
2190 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
2192 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,

2203 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
2204 #include <sys/wait.h>.
2206 2007-09-26 Thomas Quinot <quinot@adacore.com>

2209 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
2211 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
2214 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
2216 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
2219 * sem_dist.ads: Minor comment fix
2221 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
2223 2007-09-26 Javier Miranda <miranda@adacore.com>
2224 Eric Botcazou <ebotcazou@adacore.com>
2227 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
2228 indirection added to the HT_Link component of the TSD. This is required
2229 to statically allocate the TSD.
2232 Minor reordering of the declarations in the private part. Required to
2233 add a level of indirection to the contents of the TSD component HT_Link.
2234 This is required to statically allocate the TSD.
2236 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
2237 Is_Statically_Allocated set from constant objects.
2238 Do not make exported constants created by the compiler volatile.
2239 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
2242 * trans.c (Identifier_to_gnu): For constants, unshare initializers
2243 before returning them.
2245 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
2246 public part of the package.
2247 (Make_DT): Move HT_Link component out of the TSD record. For this
2248 purpose Make_DT now declares a separate object that stores the
2249 HT_Link value, and initializes the TSD component with the address
2250 of this new object. The addition of this level of indirection is
2251 required to statically allocate the TSD because the TSD cannot
2252 have variable components.
2253 (Expand_Interface_Conversion): Improve the expanded code.
2254 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
2256 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
2257 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
2258 if we are building static dispatch tables then we must not generate
2259 extra code to register the primitive because the dispatch table will
2260 be built at the end of the library package; otherwise we notify that
2261 we cannot build the static dispatch table.
2263 2007-09-26 Robert Dewar <dewar@adacore.com>
2265 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
2268 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays

2280 for thunks associated with interface types.
2282 * einfo.ads: Improve documentatation of Is_Internal
2283 (Is_Thunk): New attribute applicable to subprograms. True for thunks
2284 associated with interface types.
2285 Extensive comment fixes regarding flags that appear in all entities. The
2286 documentation is now consistent for all such flags (there were a number
2287 of errors in the documentation in this regard).
2289 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
2291 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
2292 of these procedures are passed a function call that already has
2293 build-in-place actuals (testing new flag
2294 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
2295 the case where processing continues.
2296 (Expand_Call): If the call is generated from a thunk body then we
2297 propagate the extra actuals associated with the accessibility
2298 level of the access type actuals.
2300 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
2301 of each extra formal of a protected operation to reference the
2302 corresponding extra formal of the subprogram denoted by the
2303 operation's Protected_Body_Subprogram.
2305 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
2306 N_Function_Call nodes.
2308 2007-09-26 Robert Dewar <dewar@adacore.com>
2310 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
2312 * debug.adb: Add d.s flag.
2314 2007-09-26 Gary Dismukes <dismukes@adacore.com>
2316 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
2317 debug variable so that it won't be initialized when pragma
2318 Initialize_Scalars is in effect.
2320 2007-09-26 Gary Dismukes <dismukes@adacore.com>
2322 * freeze.adb (Freeze_Entity): Remove check for preelaborable
2323 initialization of a full view. This is moved to
2324 Analyze_Package_Specification.
2326 * sem_ch7.adb (Analyze_Package_Specification): Add check for
2327 preelaborable initialization of a full view in entity loop.
2328 (Uninstall_Declarations): If entity is a use-visible compilation unit,
2329 its child units are use-visible only if they are visible child units.
2331 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
2332 whether an expression can be used within a type declaration that
2333 requires preelaborable init.
2334 (Check_Components): Replace inline code that does partial checking for
2335 preelaborable default expressions with call to
2336 Is_Preelaborable_Expression.
2337 (Has_Preelaborable_Initialization): In the case of a generic actual
2338 subtype, (that is, Is_Generic_Actual is True), return the result of
2339 applying Has_Preelaborable_Initialization to the generic actual's base
2342 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
2344 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
2345 call to Jan_1_Day _Of_Week to optimize its performance.
2346 (Is_Leap): Move the routine to the scope of Week_In_Year.
2347 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
2348 weekday on which January 1 falls of Year - 1 and Year + 1. This function
2349 avoids calling Time_Of and Split, thus making it more efficent.
2350 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
2352 * g-calend.ads (Week_In_Year): Change comment to reflect new
2355 2007-09-26 Emmanuel Briot <briot@adacore.com>
2357 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
2358 Command_Line): New types
2359 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
2360 support for defining how switches can be grouped on a command line (as
2361 is the case for -gnatw... for GNAT), and how simple switches can be
2362 used as aliases for more complex switches (-gnatwa is same as
2364 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
2365 (Start, Current_*): New subprograms
2366 Added support for parsing an array of strings in addition to the real
2368 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
2369 be moved from the body to the private part of the spec.
2370 (*): All subprograms now have an extra parameter with default value to
2371 specify which parser should be used. For backward compatibility, it
2372 defaults to parsing the command line of the application. They were also
2373 modified to properly handle cases where each of the argument does not
2374 start at index 1 (which is always true for Ada.Command_Line, but not
2375 when processing any Argument_List).
2376 (Free): New subprogram
2377 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
2378 Argument): New subprograms
2379 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
2380 special characters like ':', '=',... are now handled in a single place,
2381 which makes the code more extensible eventually.
2382 (Getopt, Full_Switch): When the switch was returned as part of the
2383 special character '*', make sure it is prepended by the switch character
2384 ('-' in general), so that the application knows whether "foo" or "-foo"
2385 was specified on the command line.
2387 2007-09-26 Florian Villoing <villoing@adacore.com>
2389 * g-dirope.adb (Remove_Dir): In case we are removing directories
2390 recursively, make sure that if an exception is raised during the
2391 processing, the current working directory is reset to its initial
2392 value before propagating the exception.
2394 2007-09-26 Vincent Celier <celier@adacore.com>
2396 * gnatbind.adb: If there are several ALI files specified and there is
2397 a main program to bind, the first ALI is expected to contain the main
2398 subprogram and the names of the binder generated files will be derived
2399 from the first ALI file name.
2400 (Gnatbind): Fix insertion character in invocation of Error_Msg
2402 2007-09-26 Vincent Celier <celier@adacore.com>
2404 * gnatcmd.adb (Check_Files): Do not include sources that have been
2405 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
2407 2007-09-26 Ed Schonberg <schonberg@adacore.com>
2409 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
2410 information about each of its index types, following the type
2411 reference for its component type.
2413 2007-09-26 Vincent Celier <celier@adacore.com>
2415 * make.adb: (Kill): New procedure (__gnat_kill imported)

2422 sources, so that the correct paths will be found.
2424 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
2426 2007-09-26 Vincent Celier <celier@adacore.com>
2428 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
2430 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
2431 Replace components Compiler_Min_Options and Binder_Min_Options with
2432 Compiler_Required_Switches and Binder_Required_Switches in record
2434 Remove components Default_Language and Config in Project_Tree_Data,
2437 * prj-attr.adb: New attributes Required_Switches (<language>) in
2438 packages Compiler and Binder.
2440 * prj-nmsc.adb: Major rewrite of the processing of configuration
2441 attributes for gprbuild. No impact on GNAT tools.
2443 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
2444 process configuration attributes: this is done in Prj.Nmsc.Check.

2446 being extended, instead of a shallow copy.
2447 (Process_Project_Tree_Phase_1): New procedure

2449 (Process): Implementation now uses the two new procedures
2451 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
2452 from the project config, not the tree config that no longer exists.
2454 2007-09-26 Vincent Celier <celier@adacore.com>

2478 ancestor of the derived type, the operations are inherited from the
2479 primary dispatch table of the parent.
2480 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
2481 when the context is an explicit type conversion.

2780 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
2781 create an abstract subprogram in the case of 'Input. For 'Output we now
2782 create a real spec/body when the type is abstract, since it can
2783 potentially be called.
2784 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
2785 body for 'Output when the type is abstract (only the creation of the
2786 body for 'Input is excluded when the type is abstract).
2787 (Stream_Operation_OK): Add an additional condition in the return
2788 statement, so that False will be returned for TTS_Stream_Input if the
2789 associated tagged type is an abstract extension. Add comments for
2791 (Expand_N_Object_Declaration): For the case of a shared passive
2792 variable, insert init proc call only after the shared variable
2793 procedures have been processed, because the IP call needs to undergo
2794 shared passive variable reference expansion, which requires these
2795 procedures to be available (and elaborated).

2804 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
2805 given a box association, the type of the component is discriminated,
2806 and the value of the discriminant is the discriminant of the enclosing
2807 type, retrieve its value from the aggregate itself, where it must have
2810 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
2811 to remove other spurious ambiguities on arithmetic operations involving
2812 literals and addresses, on systems where Address is a visible integer
2813 type, when the operator is called in functional notation.
2814 (Try_Primitive_Operation): Within an instance, a call in prefixed form
2815 is legal when the types match, even if the operation is currently
2818 2007-09-10 Ed Schonberg <schonberg@adacore.com>
2820 * sem_ch12.adb (Build_Local_Package): A formal package with no
2821 associations is legal if all formals have defaults. It is not
2822 equivalent to a formal declared with a box.

2941 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
2942 spurious ambiguities when integer literals appear in the context of an
2943 address type that is a visible integer type.
2945 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
2946 exceptions never being raised.
2947 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

2961 2007-08-31 Gary Dismukes <dismukes@adacore.com>
2963 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
2964 library-level package renaming, pass the declaration associated with
2965 the renaming's special debug variable to Qualify_Entity_Names to ensure
2966 that its encoded name is properly qualified.
2968 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
2969 occurring in the list of entities to qualify, and do not attempt to

2979 access type points to an unconstrained array.
2981 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
2983 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
2986 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect

2997 avoid very deep recursion in the front end, which was causing stack
3000 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
3001 string, and the right operand is a string literal (the case of "" &
3002 "..."), optimize by avoiding copying the right operand -- just use the
3003 value of the right operand directly.
3005 * stringt.adb (Store_String_Chars): Optimize by growing the
3006 String_Chars table all at once, rather than appending characters one by
3008 (Write_String_Table_Entry): If the string to be printed is very long,
3009 just print the first few characters, followed by the length. Otherwise,
3010 doing "pn(n)" in the debugger can take an extremely long time.
3012 * sem_prag.adb (Process_Interface_Name): Replace loop doing
3013 Store_String_Char with Store_String_Chars.

3027 clauses of subunits, ignore limited_with_clauses that are illegal and
3028 have not been fully analyzed.
3030 2007-08-31 Ed Schonberg <schonberg@adacore.com>
3032 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
3033 flag, for effiency. It is called when analyzing arithmetic operators
3034 and also for actuals in calls that are universal_integers. The flag is
3035 set for the predefined type address, and for any type or subtype
3038 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
3039 Universal_Integer, when the formal is a descendent of address and the
3040 call appears in user code.
3041 (Analyze_Selected_Component): if the prefix is a private extension, the
3042 tag component is visible.
3044 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
3047 2007-08-31 Robert Dewar <dewar@adacore.com>
3049 * s-fileio.adb (Open): Normalize file name to lower case in non-case
3050 sensitive file name systems to avoid unexpected mismatch in Vista.

3087 * gnat_ugn.texi: Add description for the new gnatpp
3088 '--separate-stmt-name' and '--use-on-new-line' options.

3101 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
3103 * misc.c (gnat_type_max_size): Constify.
3105 2007-08-16 Gary Dismukes <dismukes@adacore.com>
3107 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
3108 associated with Standard_Debug_Renaming_Type, to be used as the type of
3109 the special variables whose names provide debugger encodings for
3110 renaming declarations.
3112 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
3113 (Set_Debug_Renaming_Link): Change to set Node25.
3114 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
3115 (Write_Field25_Name): Add case for E_Variable to output
3116 "Debug_Renaming_Link".
3117 (Write_Field23_Name): Correct the output string for "Limited_View".
3119 * exp_dbug.adb: Add with and use of Tbuild.
3120 (Debug_Renaming_Declaration): Replace creation of an enumeration type
3121 and literal with creation of a variable of type
3122 Standard_Debug_Renaming_Type whose name encodes both the renamed object
3123 and the entity of the renaming declaration.
3124 (Qualify_Entity_Name): Add the delayed qualification of the entity name
3125 part of the name of a variable that has a Debug_Renaming_Link.
3127 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
3128 special type to be associated with variables that provide debugger
3129 encodings for renaming declarations.

3132 Ed Schonberg <schonberg@adacore.com>
3133 Javier Miranda <miranda@adacore.com>
3135 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
3136 ancestor part given by an aggregate to test for an unchecked conversion,
3137 since this can occur in some cases when the ancestor part is a function
3138 call, and we don't want to fall into the recursive call to this
3139 procedure in that case.
3141 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
3142 stream attributes on limited types to account for user-specified
3143 attributes as well as whether Input (resp. Output) becomes available
3144 due to Read (resp. Write) being available for the type. Change Boolean
3145 variable to the more accurate name
3146 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
3147 double-"not" predicate at beginning of return statement to more
3148 understandable form.
3150 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
3151 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
3152 in a block statement and use that as the first statement of the
3153 expanded return rather than incorrectly using the handled sequence as
3154 the first statement.
3156 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
3157 operation, generate an explicit freeze node for it rather than
3158 generating extra formals, to ensure that gigi has the proper order of
3159 elaboration for anonymous subtypes in the signature of the subprograms.
3160 (Build_In_Place_Formal): Move assertion to beginning of loop.
3161 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
3162 applied to a function call (occurs for some cases of 'Input).
3163 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
3164 applied to a function call (occurs for some cases of 'Input).
3166 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
3167 2005, generate an extended return statement enclosing the result object
3170 * freeze.adb (Freeze_Record_Type): Extend the current management of
3171 components that are access type with an allocator as default value: add
3172 missing support to the use of qualified expressions of the
3173 allocator (which also cause freezing of the designated type!)
3174 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
3175 dispatching operation, since extra formals may be needed by calls to
3176 build-in-place functions (such as stream 'Input).
3178 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
3179 formals for 'Constrained and accessibility level in the case of a
3180 predefined dispatching operation.
3182 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
3183 point, no need to find the parent node.
3185 2007-08-16 Javier Miranda <miranda@adacore.com>
3187 * exp_attr.adb (Attribute_Priority): Add missing support for entries
3190 2007-08-16 Javier Miranda <miranda@adacore.com>
3192 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
3193 is not really required and can introduce regression with the debugger.
3194 The original problem is fixed with the patch written for checks.adb.
3196 2007-08-16 Thomas Quinot <quinot@adacore.com>
3198 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
3199 Range_Check on Allocated_Table.
3201 2007-08-16 Vincent Celier <celier@adacore.com>
3203 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
3204 Including_Non_Switch set to False.
3205 (Gnatmake): For the compiler, call Test_If_Relative_Path with
3206 Including_Non_Switch set to False.
3208 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
3209 parameter Including_Non_Switch, defaulted to True. When
3210 Including_Non_Switch is False, options that are not switches and
3211 appear as relative path are not converted to absolute paths.
3213 2007-08-16 Nicolas Roche <roche@adacore.com>
3215 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
3218 * Make-lang.in: Update dependencies

3223 currently inspected is a selected component, retrieve the entity of
3225 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
3226 from the immediate ancestor of Main_Unit_Entity.
3227 (Install_Limited_Withed_Unit): Do not install the limited view of
3228 package P if P is reachable through an ancestor chain from package C
3229 and C also has a with clause for P in its body.
3230 (Has_Limited_With_Clause): New routine.
3231 (Has_With_Clause): New routine.
3233 2007-08-16 Ed Schonberg <schonberg@adacore.com>
3235 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
3236 generic for an enclosing instance is a global reference, even though
3237 its scope is the enclosing instance.
3239 2007-08-16 Gary Dismukes <dismukes@adacore.com>
3240 Javier Miranda <miranda@adacore.com>
3242 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
3243 initialize a limited object.
3244 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
3246 Make sure Has_Complex_Representation is inherited by derived type.
3248 2007-08-16 Robert Dewar <dewar@adacore.com>
3250 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
3253 2007-08-16 Ed Schonberg <schonberg@adacore.com>
3255 * sem_disp.adb (Check_Dispatching_Operation): If the operation
3256 implements an operation inherited from a progenitor interface, verify
3257 that they are subtype-conformant.
3259 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
3260 Bob Duff <duff@adacore.com>
3261 Nicolas Setton <setton@adacore.com>
3263 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
3264 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
3265 the statement which is being resolved comes from a predefined library
3266 unit, all non-predefined library interpretations are skipped.
3267 (Resolve_Op_Concat): If string concatenation was folded in the parser,
3268 but the "&" is user defined, give an error, because the folding would
3271 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
3272 the parser has folded a long sequence of concatenations of string
3275 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
3276 and "JMP_BUF" variables as artificial.
3277 (N_String_Literal): Do not use alloca for very long string literals. Use
3278 xmalloc/free instead. Otherwise the stack might overflow.
3280 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
3283 2007-08-16 Vincent Celier <celier@adacore.com>
3285 * vms_conv.adb (Process_Argument): Ensure that project related options
3286 are not put in the -cargs section when using GNAT COMPILE.
3288 2007-08-16 Robert Dewar <dewar@adacore.com>
3290 * gnat_ugn.texi: Add note on preprocessing (output file not written)
3292 2007-08-16 Thomas Quinot <quinot@adacore.com>
3294 * a-tags.adb: Minor reformatting.

3307 * a-calend-vms.adb, a-calend.adb ("+", "-", Add, Subtract): Remove
3308 calls to Check_Within_Time_Bounds.
3309 ("+", "-", Add, Subtract): Remove calls to Check_Within_Time_Bounds.
3310 (Difference): Account for possible rounding of the resulting difference

3316 s-osinte-solaris.adb, s-osinte-solaris.ads,
3317 s-osinte-freebsd.ads, s-osinte-freebsd.adb: Minor reformatting.
3319 * styleg.adb, styleg.ads, stylesw.adb, stylesw.ads: implement style
3320 switch -gnatyS. Enable -gnatyS in GNAT style check mode
3322 2007-08-14 Robert Dewar <dewar@adacore.com>
3323 Ed Schonberg <schonberg@adacore.com>
3325 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
3326 Suppress unmodified in-out parameter warning in some cases
3327 This patch is a also fairly significant change to the way suppressible
3330 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
3331 needed for access to concurrent record types generated by the expander.
3332 (Generate_Range_Check): When generating a temporary to capture the
3333 value of a conversion that requires a range check, set the type of the
3334 temporary before rewriting the node, so that the type is always
3335 properly placed for back-end use.
3336 (Apply_Float_Conversion_Check): Handle case where the conversion is
3338 (Get_Discriminal): Code reformatting. Climb the scope stack looking
3339 for a protected type in order to examine its discriminants.
3341 2007-08-14 Robert Dewar <dewar@adacore.com>
3342 Gary Dismukes <dismukes@adacore.com>
3343 Ed Schonberg <schonberg@adacore.com>
3344 Thomas Quinot <quinot@adacore.com>
3346 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
3347 a-stwisu.adb, a-strsup.adb: Fix warnings for range
3348 tests optimized out.
3350 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
3351 (Get_Allocator_Final_List): For the case of an anonymous access type
3352 that has a specified Associated_Final_Chain, do not go up to the
3354 (Expand_N_Type_Conversion): Test for the case of renamings of access
3355 parameters when deciding whether to apply a run-time accessibility
3357 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
3358 aggregate code before allocator, and ahead of declaration for
3359 temporary, to prevent access before elaboration when the allocator is
3360 an actual for an access parameter.
3361 (Expand_N_Type_Conversion): On an access type conversion involving an
3362 access parameter, do not apply an accessibility check when the
3363 operand's original node was an attribute other than 'Access. We now
3364 create access conversions for the expansion of 'Unchecked_Access and
3365 'Unrestricted_Access in certain cases and clearly accessibility should
3366 not be checked for those.
3368 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
3369 includes a type conversion of a packed component that has been expanded,
3370 recover the original expression for the object, and use this expression
3371 in the post-call assignment statement, so that the assignment is made
3372 to the object and not to a back-end temporary.
3373 (Freeze_Subprogram): In case of primitives of tagged types not defined
3374 at the library level force generation of code to register the primitive
3375 in the dispatch table. In addition some code reorganization has been
3376 done to leave the implementation clear.
3377 (Expand_Call): When expanding an inherited implicit conversion,
3378 preserve the type of the inherited function after the intrinsic
3379 operation has been expanded.
3381 * exp_ch2.ads, exp_ch2.adb
3382 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
3383 of an entry formal appearing in an assignment statement does not assign
3385 (Expand_Current_Value): Instead of calling a routine to determine
3386 whether the prefix of an attribute reference should be optimized or
3387 not, prevent the optimization of such prefixes all together.
3389 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
3390 component whose prefix is known to be of an access type is an implicit
3391 dereference and does not assign to the prefix.
3393 2007-08-14 Ed Schonberg <schonberg@adacore.com>
3394 Robert Dewar <dewar@adacore.com>
3396 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
3397 itype is visited, make an entry into table to link associated node and
3399 Add comments and correct harmless error in Build_NCT_Hash_Tables
3400 (Array_Aggr_Subtype): Associate each itype created for an index type to
3401 the corresponding range construct, and not to the aggregate itself. to
3402 maintain a one-to-one correspondence between itype and its associated
3403 node, to prevent errors when complex expression is copied.
3404 Fix mishandling of multiple levels of parens
3406 * sem_aggr.adb: Create a limited view of an incomplete type, to make
3407 treatment of limited views uniform for all visible declarations in a
3408 limited_withed package.
3409 (New_Copy_Tree): If hash table is being used and itype is visited,
3410 make an entry into table to link associated node and new itype.
3411 (Resolve_Record_Aggregate): Do not add an others box association for a
3412 discriminated record component that has only discriminants, when there
3413 is a box association for the component itself.
3415 * par-ch4.adb: Fix mishandling of multiple levels of parens
3417 2007-08-14 Robert Dewar <dewar@adacore.com>
3419 * comperr.adb: Fix problem with suppressing warning messages from gigi

3422 errout.adb (Write_Eol): Remove trailing spaces before writing the line
3423 (Write_Eol_Keep_Blanks): New procedure to write a line, including
3424 possible trailing spaces.
3425 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
3426 Fix problem with suppressing warning messages from back end
3427 Improve handling of deleted warnings
3430 Fix problem with suppressing warning messages from back end
3431 Handle setting of Static_Dispatch_Tables flag.

3450 Javier Miranda <miranda@adacore.com>
3451 Gary Dismukes <dismukes@adacore.com>
3453 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
3454 to make treatment of limited views uniform for all visible declarations
3455 in a limited_withed package.
3456 Improve warnings for in out parameters
3457 (Set_Related_Interaface/Related_Interface): Allow the use of this
3458 attribute with constants.
3459 (Write_Field26_Name): Handle attribute Related_Interface in constants.
3460 Warn on duplicate pragma Preelaborable_Initialialization
3462 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
3463 generation of a freezing node to ensure proper management of null
3464 excluding access types in the backend.
3465 (Create_Extra_Formals): Test base type of the formal when checking for
3466 the need to add an extra accessibility-level formal. Pass the entity E
3467 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
3468 originally being done in a couple of cases), to ensure that the
3469 Extra_Formals list gets set on the entity E when the first entity is
3471 (Conforming_Types): Add missing calls to Base_Type to the code that
3472 handles anonymous access types. This is required to handle the
3473 general case because Process_Formals builds internal subtype entities
3474 to handle null-excluding access types.
3475 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
3476 functions that need it, even when not marked Requires_Overriding.
3477 Improve warnings for in out parameters
3478 (Analyze_Function_Return): Warn for disallowed null return
3479 Warn on return from procedure with unset out parameter
3480 Ensure consistent use of # in error messages
3481 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
3482 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
3483 the implicit conversion of the expression done for anonymous access
3484 types. This is required to generate the code of the null excluding
3485 check (if required).
3487 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
3488 A formal parameter is never publicly referenceable outside of its body.
3489 (Check_References): For an unreferenced formal parameter in an accept
3490 statement, use the same warning circuitry as for subprogram formal
3492 (Warn_On_Unreferenced_Entity): New subprogram, taken from
3493 Output_Unreferenced_Messages, containing the part of that routine that
3494 is now reused for entry formals as described above.
3495 (Goto_Spec_Entity): New function
3496 (Check_References): Do not give IN OUT warning for dispatching operation
3497 Improve warnings for in out parameters
3498 (Test_Ref): Check that the entity is not undefinite before calling
3499 Scope_Within, in order to avoid infinite loops.
3500 Warn on return from procedure with unset out parameter
3501 Improved warnings for unused variables

3505 Gary Dismukes <dismukes@adacore.com>
3507 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
3508 (Expand_N_Attribute_Reference): Further unify the handling of the
3509 three forms of access attributes, using common code now for all three
3510 cases. Add a test for the case of applying an access attribute to
3511 an explicit dereference when the context is an access-to-interface
3512 type. In that case we need to apply the conversion to the prefix
3513 of the explicit dereference rather than the prefix of the attribute.
3514 (Attribute_Version, UET_Address): Set entity as internal to ensure
3515 proper dg output of implicit importation.
3516 (Expand_Access_To_Type): Removed.
3517 (Expand_N_Attribute_Reference): Merge the code from the three cases
3518 of access attributes, since the processing is largely identical for
3519 these cases. The substantive fix here is to process the case of a
3520 type name prefix (current instance case) before handling the case

3526 Robert Dewar <dewar@adacore.com>
3528 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
3529 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
3530 type that is an anonymous access to controlled object, establish

3554 profile is a private type whose full view has not been analyzed yet.
3555 (Freeze_Array_Type): Generate init proc for packed array if either
3556 Initialize or Normalize_Scalars is set.
3557 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
3558 constructing the new profile, copy the null_exclusion indicator for each
3559 parameter, to ensure full conformance of the new body with the spec.

3562 Create wrappers for constructor functions that need it, even when not
3563 marked Requires_Overriding.

3630 Ed Schonberg <schonberg@adacore.com>
3631 Javier Miranda <miranda@adacore.com>
3633 * exp_util.ads, exp_util.adb:
3634 This patch replaces a number of occurrences of explicit tests for N_Null
3635 with calls to Known_Null. This improves tracking of null values, since
3636 Known_Null also catches null constants, and variables currently known to
3637 be null, so we get better tracking.
3638 (Ensure_Defined): create an itype reference only in the scope of the
3640 (Side_Effect_Free): A selected component of an access type that
3641 denotes a component with a rep clause must be treated as not
3642 side-effect free, because if it is part of a linked structure its
3643 value may be affected by a renaming.
3644 (Expand_Subtype_From_Expr): For limited objects initialized with build
3645 in place function calls, do nothing; otherwise we prematurely introduce
3646 an N_Reference node in the expression initializing the object, which
3647 breaks the circuitry that detects and adds the additional arguments to
3648 the called function. Bug found working in the new patch for statically
3649 allocated dispatch tables.
3650 (Is_Library_Level_Tagged_Type): New subprogram.
3651 (Remove_Side_Effects): If the expression of an elementary type is an
3652 operator treat as a function call.
3653 (Make_Literal_Range): If the index type of the array is not integer, use
3654 attributes properly to compute the constraint on the resulting aggregate
3657 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
3658 class-wide type whose base type is an incomplete private type, leave
3659 class-wide type unfrozen so that freeze nodes can be generated
3660 properly at a later point.
3661 (Freeze_Entity, array case): Handle case of pragma Pack and component
3662 size attributre clause for same array.

4311 operations in Derive_Subprograms.
4312 (Collect_Previous_Instances): new procedure within of
4313 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
4314 unit being loaded, to ensure that the generation of global symbols is
4315 consistent in different compilation modes.
4316 (Is_Tagged_Ancestor): New function testing the ancestor relation that
4317 takes progenitor types into account.
4318 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
4319 traversing over the primitives of the formal and actual types to locate
4320 any abstract subprograms of the actual type that correspond to a
4321 nonabstract subprogram of the formal type's ancestor type(s), and issue
4322 an error if such is found.
4323 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
4324 Instantiate_Package_Body, Instantiate_Subprogram_Body):
4325 Remove bogus guard around calls to Inherit_Context.

4335 parameter to determine whether operation applies to the prefix.
4336 (Complete_Object_Operation): If actual has an access type and
4337 controlling formal is not an in_parameter, reject the actual if it is
4338 an access_to_constant type.
4339 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
4340 type, the candidate operations are found in the scope of declaration of
4341 the type, because the type has no primitive subprograms.
4342 (Analyze_Selected_Component): If prefix is class-wide, and root type is
4343 a private extension, only examine visible components before trying to
4344 analyze as a prefixed call.
4345 Change Entity_List to Type_To_Use, for better readability.
4346 (Has_Fixed_Op): Use base type when checking whether the type of an
4347 operator has a user-defined multiplication/division

4355 formal At_Any_Place indicating, when True, that we want to test for
4356 availability of the stream attribute at any place (as opposed to the
4357 current visibility context only).
4358 (Missing_Read_Write_Attributes): A stream attribute is missing for the
4359 purpose of enforcing E.2.2(8) only if it is not available at any place.
4360 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
4361 when checking the legality of an extension aggregate in a preelaborable
4362 package. Treat the literal null as a valid default expression in a
4363 component declaration for a type with preelaborable initialization.
4364 A limited interface is a legal progenitor for the designated type of a
4365 remote access to class-wide type.

4379 views that are themselves incomplete types.
4380 Handle interfaces visible through limited-with clauses.
4381 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
4382 subprogram generic actual for which we have generated a renaming.

4390 appear in the subtree to the current allocator if it is not a static
4392 (Resolve_Allocator): Perform cleanup if resolution has determined that
4393 the allocator is not a coextension.
4394 (Resolve): Skip an interpretation hidden by an abstract operator only
4395 when the type of the interpretation matches that of the context.
4396 (Resolve): When looping through all possible interpretations of a node,
4397 do not consider those that are hidden by abstract operators.
4398 (Resolve_Actuals): When verifying that an access to class-wide object
4399 is an actual for a controlling formal, ignore anonymous access to
4400 subprograms whose return type is an access to class_wide type.
4401 (Resolve_Slice): If the prefix of the slice is a selected component
4402 whose type depends on discriminants, build its actual subtype before
4403 applying range checks on the bounds of the slice.
4404 (Valid_Conversion): In an instance or inlined body, compare root types,
4405 to prevent anomalies between private and public views.
4406 (Resolve): Improve error message for ambiguous fixed multiplication
4407 expressions that involve universal_fixed multiplying operations.

4424 extraneous layer of Any wrapping for member label.
4425 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
4426 elabration statements, register the package with the name server
4427 at the beginning, not at the end, of the elaboration statements so
4428 that they can create remote access to subprogram values that designate
4429 remote subprograms from the package.
4431 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
4433 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
4434 values to compute the number of seconds since the Unix Epoc in order to
4435 account for Daylight Savings Time. Perform special processing for dates
4436 that are earlier than the Unix Epoc to obtain a negative number.

5521 System_Restrictions and initialization of the data unless there is
5522 some use of System.Restrictions in the partition.

5558 bounds of the slice to construct the required constraint checks.
5559 Improve NOT NULL error messages
5560 (Apply_Constraint_Check): If the context is a null-excluding access
5561 type, diagnose properly the literal null.

5576 Eric Botcazou <ebotcazou@adacore.com>
5577 Arnaud Charlet <charlet@adacore.com>
5579 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
5580 applicable to types that have the With_Type flag set. Returns the
5581 non-limited view of the type, if available, otherwise the type itself.
5582 For class-wide types, there is no direct link in the tree, so we have
5583 to retrieve the class-wide type of the non-limited view of the Etype.
5584 New attributes Static_Initialization and Static_Elaboration_Desired.
5585 Remove the pragma Thread_Body, and the associated flag
5586 Is_Thread_Body in entities, and all related code.

5596 components of records. Set to point to the entity of the corresponding
5598 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
5599 (Original_Access_Type): Remove, not needed.
5600 (Root_Type): Handle properly subtypes of class-wide-types.
5603 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
5604 class-wide types visible through limited-with clauses.
5605 (Try_Primitive_Operation): When examining all primitive operations of a
5606 tagged type, do not consider subprograms labeled as hidden unless they
5607 belong to a private generic type with a tagged parent.
5608 (Try_Object_Operation): Extensive rewriting, to handle properly various
5609 overloading cases, when several ancestors may have class-wide operations
5610 that are possible candidates, and when the overloaded functions return
5611 array types and have defaulted parameters so that the call may be
5612 interpreted as an indexing.
5613 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
5614 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
5615 successive actuals before analyzing the call itself.
5616 (Try_Primitive_Operation): A primitive operation is compatible with the
5617 prefix if the prefix has a synchronized type and the type of the formal
5618 is its corresponding record, as can be the case when the primitive
5619 operation is declared outside of the body of the type.
5620 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
5621 perform homonym traversal, looking for class-wide operation matches
5622 (formerly done in statements of Try_Class_Wide_Operation). Matches on
5623 access parameters are now restricted to anonymous access types.
5624 (Mark_Allocator): An allocator with a discriminant association parent is
5626 (Try_One_Prefix_Interpretation): If the type of the object is
5627 incomplete, as can be happen when it is a limited view obtained through
5628 a limited_with_clause, the selected component is not part of a prefixed
5630 (Complete_Object_Operation): Diagnose properly an object that is not
5631 aliased when the corresponding controlling formal is an access
5633 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
5634 ambiguous calls in prefixed notation, where two primitives differ only
5635 in that the controlling argument of one is an access parameter.
5637 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
5638 whether a function that returns an unconstrained type can be inlined.
5639 (Process_Formals): Diagnose properly the illegal use of an incomplete
5640 type in the profile of an access_to_subprogram declaration.
5641 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
5642 operations are attached to the corresponding record.
5643 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
5644 When processing a primitive of a concurrent type which implements an
5645 interface change the type of all controlling formals to that of the
5646 corresponding record type.
5647 (Check_Synchronized_Overriding): Relax the conditional logic when trying
5648 to determine the tagged type to which a primitive belongs.
5649 (Check_Conventions): Capture condition to ignore a primitive operation
5650 (which is shared between the loop in Check_Conventions and the one in
5651 Check_Convention) in a new local function Skip_Check.
5652 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
5653 confusion with Check_Conventions' own Prim_Op local variable.
5654 (Create_Extra_Formals): Test for a tagged result type rather than a
5655 controlling result when determining whether to add a BIP_Alloc_Form
5656 formal and a BIP_Final_List formal to the function.
5657 (Check_Conformance); For parameters that are anonymous access types,
5658 subtype conformance requires that the not null and the constant
5659 indicators must match
5660 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
5661 to retrieve the appropriate type when processing a concurrent type
5662 declared within a generic. Minor comment reformatting. Change invocation
5663 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
5665 (Analyze_Subprogram_Body): If the return type of a function is an
5666 anonymous access to the limited view of a class-wide type, and the
5667 non-limited view of the type is available, update the type of the
5668 function so that code can be generated.
5669 (Process_Formals): In case of access-subtype itype whose designated
5670 type is also an itype (situation that happens now with access to
5671 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
5672 attribute to avoid backend problems.
5673 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
5674 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
5675 anonymous types' designated types are same before testing
5676 Subtypes_Statically_Match.
5677 (Create_Extra_Formals): Test for a named access parameter that is a
5678 controlling formal as an additional condition for adding an
5679 accessibility level formal. This can occur in the subp type created for
5680 dispatching calls in Expand_Dispatching_Call, and allows calling
5681 Create_Extra_Formals from that procedure rather than special-casing the
5682 extra formals there.
5683 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
5684 when the function has a controlling result.
5685 (Check_Returns): Add much more knowledge of the optimization of local
5686 raise statements to gotos, to retain proper warnings in this case.
5687 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
5688 nodes when looking for last statement.
5690 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
5691 class-wide types visible through limited with clauses.
5692 (Add_One_Interp): If the operands are anonymous access types, the
5693 predefined operator on universal_access is immediately visibles
5694 (Find_Unique_Type): Handle anonymous access to subprogram types just as
5695 other anonymous access types.
5696 (Disambiguate): Take into account CIL convention.
5697 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
5699 2007-06-06 Robert Dewar <dewar@adacore.com>
5701 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
5702 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,

5704 Fix lower bound of tables.
5707 * nlists.adb: Ditto.
5708 (Prev_Node, Next_Node): Change index type to Int so that it properly
5709 covers the range First_Node_Id - 1 up.

5713 Bob Duff <duff@adacore.com>
5714 Hristian Kirtchev <kirtchev@adacore.com>
5716 * exp_aggr.ads, exp_aggr.adb:
5717 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
5718 in extension aggregates.
5719 (Flatten): Other conditions being met, an aggregate is static if the
5720 low bound given by component associations is different from the low
5721 bound of the base index type.
5722 (Packed_Array_Aggregate_Handled): If the component type is itself a
5723 packed array or record, the front-end must expand into assignments.
5724 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
5725 Init_Pr, instead of Ancestor_Is_Expression.
5726 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
5727 coextension chain root, either generate a list controller or use the
5728 already existing one.
5729 (Static_Array_Aggregate): New procedure to construct a positional
5730 aggregate that can be handled by the backend, when all bounds and
5731 components are compile-time known constants.
5732 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
5733 types covering interface types into assignments.
5734 (Replace_Type): move to Build_Record_Aggr_Code.
5735 (Expand_Record_Aggr_Code): if the target of the aggregate is an
5736 interface type, convert to the definite type of the aggregate itself,
5737 so that needed components are visible.
5738 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
5739 components and the context is an extended return statement do not
5740 create a transient block for it, to prevent premature finalization
5741 before the return is executed.
5742 (Gen_Assign): Do not generate a call to deep adjust routine if the
5743 component type is itself an array of controlled (sub)-components
5744 initialized with an inner aggregate.
5745 (Component_Check): New name for Static_Check. This name is now more
5746 appropriate, and documentation is added which was missing.
5747 (Component_Check): Add test for bit aligned component value
5748 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
5749 Tagged_Comps, name is more appropriate given added function below.
5750 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

5753 Javier Miranda <miranda@adacore.com>
5754 Robert Dewar <dewar@adacore.com>
5756 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
5757 Terminated: Add unchecked type conversion from System.Address to
5758 System.Tasking.Task_Id when calling the predefined primitive
5760 Disable new Ada 05 accessibility check for JVM.NET targets, which
5761 cannot be implemented in a practical way.
5762 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
5763 the sources always references the tag of the actual object. Therefore,
5764 if 'Tag is applied in the sources to class-wide interface objects we
5765 generate code that displaces "this" to reference the base of the object.
5766 (Expand_N_Attribute_Reference, case Size): Return specified size if
5768 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
5769 has code that displaces the pointer of the object to manage interface
5770 types. However this code must not be executed when the prefix is a
5771 subprogram. This bug caused the wrong expansion of the internally
5772 generated assignment that fills the dispatch table when the primitive
5773 is a function returning a class-wide interface type.
5774 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
5775 Set_Attribute_Name for Name_Unaligned_Valid.
5777 2007-06-06 Ed Schonberg <schonberg@adacore.com>
5778 Gary Dismukes <dismukes@adacore.com>
5780 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
5781 If the initialization is the equivalent aggregate of the initialization
5782 procedure of the type, do not remove it.
5783 (Expand_N_Attribute_Definition_Clause): Exclude access variables
5784 initialized to null from having their expression reset to empty and
5785 note this exception in the comment.

5803 mismatched conventions.
5804 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
5806 (Analyze_Attribute, case 'Access): If the type of the prefix is a
5807 constrained subtype for a nominal unconstrained type, use its base type
5808 to check for conformance with the context.
5809 (Resolve_Attribute): Remove test of the access type being associated
5810 with a return statement from condition for performing accessibility
5811 checks on access attributes, since this case is now captured by
5812 Is_Local_Anonymous_Access.
5813 (Analyze_Access_Attribute): Set Address_Taken on entity
5814 (Analyze_Attribute, case Address): Set Address_Taken on entity
5815 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
5816 validating an access attribute whose prefix is a current instance.
5817 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
5818 applied to dispatching operations, if freezing is required then we set
5819 the attribute Has_Delayed_Freeze in the prefix's entity.
5820 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
5821 current scope if access of local subprogram taken
5822 (Analyze_Access_Attribute): Check legality of self-reference even if the
5823 expression comes from source, as when a single component association in
5824 an aggregate has a box association.
5825 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
5826 the prefix if it is a protected operation and the attribute is
5827 Unrestricted_Access.
5828 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
5829 reference to the base type of the context, to force a constraint check
5830 when the context is an access subtype with an explicit constraint.
5831 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
5832 node is rewritten as an interface conversion. leave unanalyzed after
5833 resolution, to ensure that type checking against the context will take

5837 Javier Miranda <miranda@adacore.com>
5838 Robert Dewar <dewar@adacore.com>
5840 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
5841 wrapper when the full view of the controlling type of an inherited
5842 function that dispatches on result implements interfaces.
5843 (Expand_N_Object_Declaration): In cases where the type of the
5844 declaration is anonymous access, create finalization list for it.
5845 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
5846 if the object has no explicit initialization, to match description of
5847 functionality of pragam Persistent_BSS.
5848 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
5849 new function to build static aggregates, to replace initialization call
5850 when static initialization is desired.
5851 (Freeze_Type): Generate a list controller for an access type whenever
5852 its designated type has controlled anonymous access discriminants.
5853 (Build_Equivalent_Aggregate): New procedure to compute a static
5854 aggregate to be used as default initialization for composite types,
5855 instead of a generating a call to the initialization procedure for the
5857 (Build_Initialization_Call): When available, replace a call to the
5858 initialization procedure with a copy of the equivalent static aggregate
5860 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
5861 declarations for objects of a class-wide interface type, rather than
5862 just identifiers, to prevent visibility problems.
5863 (Expand_N_Object_Declaration): When expanding the declaration for an
5864 object of a class-wide interface type, preserve the homonym chain of
5865 the original entity before exchanging it with that of the generated
5866 renaming declaration.
5867 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
5868 active, because there is no way to handle the exception.
5869 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
5870 to do a minimum decoration of the Access_Disp_Table list.
5871 (Expand_Record_Controller): Avoid the addition of the controller between
5872 the component containing the tag of a secondary dispatch table and its
5873 adjacent component that stores the offset to the base of the object.
5874 This latter component is only generated when the parent type has
5875 discriminants ---documented in Add_Interface_Tag_Components).
5876 (Apply_Array_Size_Check): Removed, no longer needed.
5877 (Expand_N_Full_Type_Declaration): If the type has anonymous access
5878 components, create a Master_Entity for it only if it contains tasks.
5879 (Build_Init_Procedure): Suppress the tag assignment compiling under
5881 (Freeze_Record_Type): Remove code associated with creation of dispatch
5883 (Init_Secondary_Tags): Update type of actuals when generating calls to
5884 Ada.Tags.Set_Offset_To_Top
5885 (Stream_Operation_OK): Disable use of streams compiling under no
5887 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
5888 if Has_Init_Expression set.
5889 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
5890 Register_Primitive, which provides the same functionality.
5891 (Requires_Init_Proc): Return false in case of interface types.
5892 (Add_Secondary_Tables): Use the new attribute Related_Interface to
5894 (Predefined_Primitive_Freeze): Do not assume that an internal entity
5895 is always associated with a predefined primitive because the internal
5896 entities associated with interface types are not predefined primitives.
5897 Therefore, the call to Is_Internal is replaced by a call to the
5898 function Is_Predefined_Dispatching_Operation.
5899 (Make_Eq_If): When generating the list of comparisons for the
5900 components of a given variant, omit the controller component that is
5901 present if the variant has controlled components.
5903 2007-06-06 Javier Miranda <miranda@adacore.com>
5904 Hristian Kirtchev <kirtchev@adacore.com>
5905 Bob Duff <duff@adacore.com>
5907 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
5908 handle the creation of finalization lists and calls for nested
5909 coextensions when the root of the chains is part of a return statement.
5910 (Inside_A_Return_Statement): New function inside Complete_Coextension_
5912 (Expand_Record_Equality): Skip components that are interface types.
5913 (Displace_Allocator_Pointer): Add missing support for interface subtypes
5914 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
5915 with Rewrite_Coextension. Change the condition for detecting coextension
5917 (Is_Local_Access_Discriminant): Removed.
5918 (Rewrite_Coextension): New routine which rewrites a static coextension
5919 as a temporary and uses its unrestricted access in the construction of
5921 (Complete_Coextension_Finalization): New routine. Generate finalization
5922 attachment calls to all delayed coextensions.
5923 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
5924 the allocator is not a coextension itself and has delayed coextensions.
5925 If the current allocator is controlled, but also a coextension, delay
5926 the generation of the finalization attachment call.
5927 Rename local variable "Node" to "Nod" in order to avoid confusion with
5929 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
5930 limited types that are not inherently limited. Such an allocator is
5931 illegal, but is generated by the expander for a return statement, to
5932 copy the result onto the secondary stack. This is the only case where a
5933 limited object can be copied. Generate code to displace the pointer
5934 to the object if the qualified expression is a class-wide interface
5935 object. Such displacement was missing and hence the copy of the object
5937 (Apply_Accessibility_Check): Handle allocated objects initialized in
5939 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
5940 and Expand_Allocator_Expression. Allocating class-wide interface objects
5941 this routine displaces the pointer to the allocated object to reference
5942 the component referencing the corresponding secondary dispatch table.
5943 Expand_Allocator_Expression): Add missing support to allocate class-wide
5944 interface objects initialized with a qualified expression.
5945 (Get_Allocator_Final_List): Test for an anonymous access type that is a
5946 function result type, and use the finalization list associated with the
5947 function scope in that case (such an anonymous type should not be
5948 treated like an access parameter's type).
5950 2007-06-06 Ed Schonberg <schonberg@adacore.com>
5951 Gary Dismukes <dismukes@adacore.com>
5952 Javier Miranda <miranda@adacore.com>
5954 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
5955 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
5956 required exception handler.
5957 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
5958 properly the case of a function whose return type is a limited
5959 class-wide interface type. Modify the code of the accessibility
5960 check to handle class-wide interface objects. In this case we need to
5961 displace "this" to reference the primary dispatch table to get access
5962 to the TSD of the object (to evaluate its accessibility level).
5963 (Expand_N_Extended_Return_Statement): Test for a tagged result type
5964 rather than a controlling result as one of the conditions for
5965 generating tests of the implicit BIP_Alloc_Form formal. The
5966 initialization assignment is also handled according to whether the
5967 result is tagged instead of controlling.
5968 In the case where the init assignment is inserted in the "then" part of
5969 the allocation conditional, rewrite the target to be a dereference of
5970 the implicit BIP_Object_Access formal.
5971 If the returned value is unconstrained and created on the secondary
5972 stack, mark the enclosing block and function so that the secondary
5973 stack is not reclaimed on return.
5974 Treat returns from functions with controlling results similarly to
5975 returns from functions with unconstrained result subtypes.
5976 If the object returned is unconstrained, and an allocator must be
5977 created for it, analyze the allocator once the block for the extended
5978 return is installed, to ensure that finalizable components
5979 of the expression use the proper finalization list. Guard the call to
5980 Move_Final_List with a check that there is something to finalize.
5981 (Make_Tag_Ctrl_Assignment): Use "old" handling
5982 of controlled type assignment for virtual machines, since new code uses
5983 unsupported features (such as direct access to bytes in memory).
5985 2007-06-06 Gary Dismukes <dismukes@adacore.com>
5986 Ed Schonberg <schonberg@adacore.com>
5988 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
5989 accessibility actual, check for the case of an aliased object that has
5990 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
5991 we fall into processing for the attribute rather than the name of the
5993 (Expand_Inline_Call): If an actual is a literal, and the corresponding
5994 formal has its address taken in the body, create a temporary to capture
5995 value. If the return type is a limited interface, do not treat the
5996 return value as Controlled.
5997 (Is_In_Place_Function): If the return type is a limited interface,
5998 treat as returning in place. The actual returned object may not always
5999 be limited, but the caller has to assume that it is returned in place.
6000 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
6001 context of an allocator, use the correct finalization chain (that is,
6002 the chain belonging to the access type, rather than the chain belonging
6003 to the current scope).
6004 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
6005 result type rather than a controlling result as a precondition for
6006 adding an allocation form actual to a build-in-place call.
6007 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
6008 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
6009 primitive in the dispatch tables. This work is now done by Make_DT when
6011 (Register_Predefined_DT_Entry): Removed.
6012 (Add_Return): If end label is not present, use sloc of last statement
6013 for generated return statement in procedure, for better gdb behavior
6015 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
6016 object address nodes to ensure proper processing by routines like
6018 (Expand_Call): Fix generation of validity check for parameter
6019 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
6020 the allocation form parameter if the result subtype is constrained,
6021 except when the function has a controlling result.
6022 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
6023 rather than Is_Controlled and Has_Controlled_Component, since we want to
6024 include class-wide result types in this treatment. Also test for a
6025 controlling result, since that also requires passing a finalization
6027 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
6028 even when the result subtype is constrained, to handle calls involving
6029 controlling results.
6030 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
6031 is now called even when the result subtype is constrained, to handle
6032 calls involving controlling results.
6033 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
6034 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
6035 now performs the test).
6036 (Make_Build_In_Place_Call_In_Object_Declaration):
6037 Add_Alloc_Form_Actual_* is now called even when the result subtype is
6038 constrained, to handle calls involving controlling results.
6039 (Add_Return): Accomodate rewritten pattern from local raise to goto
6040 transformation, so that we still recognize an transfer statement
6041 and do the right thing here in that case.
6042 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
6043 and end of subprogram code.
6044 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
6045 support for primitives that are functions (without formals) with a
6047 (Inherited_From_Formal): If the actual subtype has not generic parent
6048 type, it is not an actual for a formal derived type, and there is no
6049 operation to inherit from the formal.
6051 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6052 Thomas Quinot <quinot@adacore.com>
6054 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
6055 inserted cleanup code appropriately for GDB use.
6056 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
6057 exception handler for Deep_Adjust or Deep_Finalize.
6058 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
6059 Raise_From_Controlled_Operation is available, use a call to that
6060 subprogram instead of a plain "raise Program_Error" node to raise
6061 Program_Error if an exception is propagated from an Adjust or Finalize
6063 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
6064 appears in the optional statement list of a triggering alternative, the
6065 scope actions can be inserted directly there, and not in the list that
6066 includes the asynchronous select itself.
6068 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6069 Robert Dewar <dewar@adacore.com>
6070 Hristian Kirtchev <kirtchev@adacore.com>
6072 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
6073 generated exception handler appropriately when debugging generated code.
6074 Deal properly with No_Exception_Propagation restriction mode.
6075 (Expand_N_Abort_Statement): Add an unchecked type conversion from
6076 System.Address to System.Tasking.Task_Id when processing the result of
6077 the predefined primitive _disp_get_task_id.
6078 (Expand_N_Asynchronous_Select): Clarify comment.
6079 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
6080 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
6081 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
6082 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
6083 privals and for generated call to Complete_Entry_Body, for better gdb
6085 (Copy_Result_Type): Utility to construct a parameter and result profile
6086 for protected functions whose return type is an anonymous access to
6088 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
6090 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
6091 point when the local-raise-to-goto transformation has taken place.
6093 2007-06-06 Javier Miranda <miranda@adacore.com>
6094 Nicolas Setton <setton@adacore.com>
6096 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
6097 functionality when the backend is generating code.
6098 Otherwise any serious error
6099 reported by the backend calling the frontend routine Error_Msg
6100 changes the Compilation_Mode to Check_Semantics, disables the
6101 functionality of this routine and causes the generation of
6102 spureous additional errors.
6104 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
6105 debugging information now generated by the compiler for fat-pointer
6107 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
6109 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.

6115 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
6116 For a remote call to a function with a classwide return type, apply an
6117 E.4(18) check to the returned value.
6118 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
6119 stream attributes of the designated type of an RACW, as they are not
6120 dispatching primitive operations.
6122 2007-06-06 Geert Bosch <bosch@adacore.com>
6124 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
6126 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
6128 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
6129 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
6131 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
6133 2007-06-06 Javier Miranda <miranda@adacore.com>
6135 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
6136 attribute compiling package Ada.Tags under No_Run_Time_Mode.
6138 2007-06-06 Javier Miranda <miranda@adacore.com>
6140 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
6141 deallocation of class-wide interface objects.
6142 (Expand_Dispatching_Constructor_Call): Take into account that if the
6143 result of the dispatching constructor is an interface type, the
6144 function returns a class-wide interface type; otherwise the returned
6145 object would be actual. The frontend previously accepted returning
6146 interface types because Expand_Interface_Actuals silently performed
6147 the management of the returned type "as if" it were a class-wide
6149 (Expand_Dispatching_Constructor_Call): Replace call to
6150 Make_DT_Access_Action by direct call to Make_Function_Call.
6152 2007-06-06 Robert Dewar <dewar@adacore.com>
6153 Ed Schonberg <schonberg@adacore.com>
6155 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
6156 compute masking constant, since we now set Esize properly to the
6158 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
6159 to match the alignment.
6160 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
6161 packed arrays of 8 bits or less.
6163 * freeze.adb (Freeze_Entity): When freezing the formals of a
6164 subprogram, freeze the designated type of a parameter of an access type
6165 only if it is an access parameter.
6166 Increase size of C convention enumeration object
6167 (Freeze_Entity, array type case): Make sure Esize value is properly
6168 adjusted for the alignment if it is known.
6169 (Freeze_Entity, array type case): When checking bit packed arrays for
6170 the size being incorrect, check RM_Size, not Esize.
6171 (Freeze_Record_Type): Check for bad discriminated record convention
6172 (In_Exp_Body): Return true if the body is generated for a subprogram
6173 renaming, either an attribute renaming or a renaming as body.
6174 (Check_Itype): If the designated type of an anonymous access component
6175 is a non-protected subprogram type, indicate that it is frozen, to
6176 prevent out-of-scope freeze node at some subsequent call.
6177 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
6178 only if the subprogram is neither imported nor exported, as well as the
6179 NCA descriptor class if the subprogram is exported.

6186 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
6187 default initialization on an imported object, when there is no
6188 initialization call generated for it.
6189 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
6192 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
6193 Static_Elaboration_Desired.
6194 Remove pragma Thread_Body.
6195 Implement a new pragma No_Body
6196 Removes the Explicit_Overriding pragma
6197 Remove Optional_Overriding pragma
6198 (Prag): Deal with Universal_Aliasing.
6199 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
6200 Pragma_CIL_Constructor): New names.
6202 * sem_cat.adb (Validate_Object_Declaration): An initialization that
6203 uses the equivalent aggregate of a type must be treated as an implicit
6205 (Get_Categorization): Check a unit for pragma Preelaborate only if it
6206 has none of the other categories.
6207 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
6208 to apply Import to an object renaming declaration.
6210 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
6211 from a C++ class should be declared as limited and that it will be
6212 considererd limited.
6213 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
6214 should be declared as limited and that it will be considererd limited.
6215 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
6216 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
6217 (Analyze_Pragma): Deal with Universal_Aliasing.
6218 (Sig_Flags): Likewise.
6219 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
6220 (Overflow_Checks_Unsuppressed): New flag.
6221 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
6222 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
6223 case of JVM or .NET targets, and compiling user code.
6224 Add debugging convenience routine rv

6228 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
6230 (Build_Elementary_Input_Call): For floating-point use right type in the
6231 absence of strange size or stream size clauses.
6232 (Build_Elementary_Write_Call): Same fix
6233 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
6234 set to value that does not match base type size.
6236 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6238 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
6239 object of a limited type can be initialized with a call to a function
6240 that returns in place. If the limited type has unknown discriminants,
6241 and the underlying type is a constrained composite type, build an actual
6242 subtype from the function call, as is done for private types.
6243 (Side_Effect_Free): An expression that is the renaming of an object or
6244 whose prefix is the renaming of a object, is not side-effect free
6245 because it may be assigned through the renaming and its value must be
6246 captured in a temporary.
6247 (Has_Controlled_Coextensions): New routine.
6248 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
6249 as is done for other limited types.
6250 (Non_Limited_Designated_Type): new predicate.
6251 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
6253 Remove all handling of with_type clauses.
6255 * par-ch10.adb: Remove all handling of with_type clauses.
6257 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
6258 checksum if the main source could not be parsed.
6259 (Loat_Unit): When processing a child unit, determine properly whether
6260 the parent unit is a renaming when the parent is itself a child unit.
6261 Remove handling of with_type clauses.
6263 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

6271 Remove all handling of with_type clauses.
6272 (Exception_Junk): Can now be set in N_Block_Statement
6274 2007-06-06 Vincent Celier <celier@adacore.com>
6275 Robert Dewar <dewar@adacore.com>
6277 * frontend.adb (Frontend): Return immediately if the main source could

8126 that use (a subtype of) the class-wide type of the enclosing type.

8129 Check_Anonymous_Access_Components rather than Empty.
8130 (Make_Incomplete_Type_Declaration): Add test for case where the type has
8131 a record extension in deciding whether to create a class-wide type,

8175 (Collect_Arguments): Do not check for sources outside of projects.
8176 Do not collect arguments if project is externally built.
8177 (Compile_Sources): Do nothing, not even check if the source is up to
8178 date, if its project is externally built.
8179 (Compile): When compiling a predefined source, add -gnatpg
8180 as the second switch, after -c.
8181 (Compile_Sources): Allow compilation of Annex J renames without -a
8182 (Is_In_Object_Directory): Check if the ALI file is in the object
8183 even if there is no project extension.
8184 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
8185 gnatbind if the ALI file effectively exists.
8186 (Initialize): Add the directory where gnatmake is invoked in front of
8187 the path if it is invoked from a bin directory, even without directory
8188 information, so that the correct GNAT tools will be used when spawned
8189 without directory information.

8212 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
8213 when -gnatg is not specified.
8214 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
8215 there is no need to generate always a record_definition_node in case
8216 of synchronized interface types.
8217 (SIS_Entry_Active): Initialize global variable to False
8218 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

8239 If the array component is a discriminated record, the array aggregate
8240 is non-static even if the component is given by an aggregate with
8242 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
8243 (Convert_Aggr_In_Allocator): If the allocator is for an access
8244 discriminant and the type is controlled. do not place on a finalization
8245 list at this point. The proper list will be determined from the
8247 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
8248 initialize record controller if needed, before the components, to ensure
8249 that they are properly finalized.
8250 (Build_Record_Aggr_Code): For the case of an array component that has a
8251 corresponding array aggregate in the record aggregate, perform sliding

8259 run-time subprogram Set_External_Tag by call to Build_Set_External_Tag.
8261 * exp_ch4.adb (Expand_Allocator_Expression): Don't perform a run-time
8262 accessibility on class-wide allocators if the allocator occurs at the
8263 same scope level as the allocator's type. The check is guaranteed to
8264 succeed in that case, even when the expression originates from a
8265 parameter of the containing subprogram.
8266 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
8267 under No_Dispatching_Calls restriction. During the semantic analysis
8268 we already notified such violation.
8269 (Tagged_Membership): Constant folding. There is no need to check
8270 the tag at run-time if the type of the right operand is non
8271 class-wide abstract.

8283 run-time subprogram Get_Access_Level by call to Build_Get_Access_Level.
8285 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
8286 initialize most the TSD components by means of an aggregate.
8287 Modify the declaration of the object containing the TSD
8288 because we now expand code that has a higher level of abstraction.
8289 The TSD has a discriminant containing the Inheritance Depth Level,
8290 value that is used in the membership test but also to fix the size
8291 of the table of ancestors.
8292 (Expand_Interface_Conversion): Insert function body at the closest place
8293 to the conversion expression, to prevent access-before-elaboration
8294 errors in the backend.

8319 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
8320 (Expand_Dispatching_Call): Replace generation of call to the run-time
8321 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
8322 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
8324 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
8325 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

8329 (Init_Predefined_Interface_Primitives): Replace generation of call to
8330 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
8333 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to

8335 returns an actual parameter expression for both named and positional
8338 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
8339 check violation of restriction No_Dispatching_Calls.
8340 (Check_Controlling_Type): A formal of a tagged incomplete type is a
8341 controlling argument.

8344 First/Next_Component_Or_Discriminant
8345 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
8346 (Find_Implemented_Interface): Removed. All the calls to this subprogram

8348 provided by the function Has_Abstract_Interfaces.
8349 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
8350 support concurrent types implementing interfaces.
8351 (Find_Implemented_Interface): Removed. All the calls to this subprogram

8353 provided by the function Has_Abstract_Interfaces.
8354 (Remove_Side_Effects): replace Controlled_Type by
8355 CW_Or_Controlled_Type whenever the issue is related to
8356 using or not the secondary stack.
8358 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
8359 P_Interface_Type_Definition to fulfill the new interface (the formal
8360 Is_Synchronized is no longer required).
8362 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
8363 Update dependencies.
8365 * exp_atag.ads, exp_atag.adb: New file

8368 Bob Duff <duff@adacore.com>
8369 Cyrille Comar <comar@adacore.com>
8371 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
8372 anonymous, use finalization list of enclosing dynamic scope.
8373 (Expand_N_Package_Declaration): For a library package declaration
8374 without a corresponding body, generate RACW subprogram bodies in the
8375 spec (just as we do for the task activation call).
8376 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
8377 Is_Abstract_Type. Make sure these are called only when appropriate.
8378 Remove all code for DSP option
8379 (CW_Or_Controlled_Type): new subprogram.

8389 (Build_Find_Body_Index): Adjust for above change.
8390 (Entry_Index_Expression): Likewise.
8391 (Is_Potentially_Large_Family): New function extracted from...
8392 (Collect_Entry_Families): ...here. Call it to detect whether the family
8393 is potentially large.
8394 (Build_Entry_Count_Expression): If the family is potentially large, call
8395 Family_Size with 'Cap' set to true.
8396 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
8397 a protected version of an operation declared in the private part of
8398 a protected object, because they may be invoked through a callback.
8399 (Set_Privals): If the type of a private component is an anonymous access
8400 type, do not create a new itype for each protected body.
8401 If the body of a protected operation creates
8402 controlled types (including allocators for class-widetypes), the
8403 body of the corresponding protected subprogram must include a
8405 (Build_Activation_Chain_Entity): Build the chain entity for extended
8407 (Type_Conformant_Parameters): Use common predicate Conforming_Types
8408 to determine whether operation overrides an inherited primitive.

8422 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
8423 E_Constant, depending upon Variable formal.
8424 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
8425 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
8426 parameter that requires an extra constrained parameter, declare
8427 temporary for actual as a variable, not a constant.
8428 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
8429 the unit being compiled is the one that contains the stub type.
8430 Change primitive operation name for the RACW associated with a RAS
8431 from Call to _Call so it cannot clash with any legal identifier.

8434 (Append_RACW_Bodies): New subprogram.
8435 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to

8437 When expanding a package body, this list correspond to the
8438 statements in the HSS at the end of the pacakge.
8439 When expanding a package spec, this list correspond to the
8441 (Add_Receiving_Stubs_To_Declarations): Append the function
8442 registering the receiving stubs at the end of the 'Stmts' list.
8443 (RCI_Package_Locator): Pass the new Version generic formal when
8444 instantiating a RCI_Locator package.
8445 (Build_From_Any_Function): To compute the High bound for an
8446 unconstrained array actual, we add the Low bound with the length.
8447 Thus we must convert the low bound and the length to an appropriate
8448 type before doing the sum.
8449 (Build_Subprogram_Receiving_Stubs, PolyORB):
8450 * Retrieve the extra formals parameters at the
8451 end of the parameter stream.
8452 * Use Move_Any_Value to write back out parameters
8453 after executing the request as it is more efficient
8454 than Copy_Any_Value.
8455 * Build the any containing Extra Formals with the
8456 appropriate typecode.
8457 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
8458 empty Component_List.
8459 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
8460 the tree the declaration for an object that serves as actual parameter
8461 in server-side stubs.

8471 function with the first not implicit parent type.
8472 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
8473 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
8474 typecode from the Etype. Therefore we retrieve the correct typecode
8475 with a call to Get_Any_Type.
8476 (Copy_Specification): Do controlling formal type substitution based on
8477 Is_Controlling_Formal flag, instead of caller-provided object type.
8478 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
8479 a RACW primitive operation, we might get a subprogram declaration for an
8480 ancestor of the RACW designated type (not for the designated type
8481 itself), in the case where this operation is inherited. In this case we
8482 have no easy means of determining the original tagged type for which
8483 the primitive was declared, so instead we now rely on
8484 Copy_Specification to use the Is_Controlling_Formal flag to determine
8485 which formals require type substitution.

8491 GNAT.Current_Exception are not allowed if pragma Restrictions
8492 (No_Exception_Propagation) is set and in any case make the associated
8493 handler unsuitable as a target for a local raise statement.
8494 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
8495 run-time subprogram CW_Membership by call to Build_CW_Membership.
8496 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
8497 by a function call, a temporary must be created before expanding the
8498 Constructor_Call itself, to prevent out-of-order elaboration in the
8499 back-end when stack checking is enabled..
8501 2007-04-06 Ed Schonberg <schonberg@adacore.com>
8503 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
8504 result are the bounds of the left operand, not the right.
8506 2007-04-06 Ed Schonberg <schonberg@adacore.com>

8627 standard 8bits encoding.
8628 (WS2SU): As above but converting from wide-sring to string.
8629 This is needed as it is necessary to have access to both versions in the
8630 runtime for the form parameter encoding support.
8631 This set of patch add support for the encoding form parameter.
8632 (S2WS): Improve implementation to handle cases where the filename is not
8633 UTF-8 encoded. In this case we default to using the current code page
8636 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
8637 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

8681 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
8682 __gnat_adjust_context_for_raise.
8683 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
8684 implementation of floating point operations as native x86 targets.
8685 So the FPU should be initialized in the same way using finit. Fix
8686 floating point operations accuracy issues.
8687 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
8688 member in struct sigaction, so as to avoid warning for incompatible

8707 Modify the loop that collects type references, to include interface
8708 types that the type implements. List each of these interfaces when
8709 building the entry for the type.
8710 (Generate_Definition): Initialize component Def and Typ of new entry
8711 in table Xrefs, to avoid to have these components unitialized.

8755 2007-04-06 Robert Dewar <dewar@adacore.com>
8757 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
8758 it no longer destroys the contents of Name_Buffer or Name_Len and
8759 non-standard and invalid names are handled better.
8760 (Get_Decoded_Name_String): Improve performance by using
8761 Name_Has_No_Encodings flag in the name table.
8762 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
8763 Used for debugging printouts.
8765 2007-04-06 Robert Dewar <dewar@adacore.com>
8766 Javier Miranda <miranda@adacore.com>

8774 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
8775 illegal in Ada 95, in cases where it is legal. Change the warnings to
8776 errors in other cases. Don't give the error unless the "not null"
8777 parses properly. Correct the source position at which the error occurs.
8778 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
8779 P_Null_Exclusion, to suppress "not null" warnings.

8855 the default project path, initially done during elaboration of the
8857 If the prefix returned by Sdefault is null, get the prefix from a call
8858 to Executable_Prefix_Path.
8859 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is

8865 (Record_Other_Sources): Idem.
8866 (Locate_Directory): Add the possibility to create automatically missing
8867 directories when Setup_Projects is True.

8909 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
8910 full word is no longer compared twice.
8912 2007-04-06 Ed Schonberg <schonberg@adacore.com>
8914 * sem_ch10.adb (Install_Limited_Context_Clauses.
8915 Expand_Limited_With_Clause): Use a new copy of selector name in the
8916 call to Make_With_Clause. This fixes the tree structure for ASIS
8917 purposes. Nothing is changed in the compiler behaviour.
8918 (Process_Body_Clauses): Handle properly use clauses whose prefix is
8920 (Install_Limited_With_Clauses): Do not install non-limited view when it
8921 is still incomplete.
8923 2007-04-06 Ed Schonberg <schonberg@adacore.com>
8924 Gary Dismukes <dismukes@adacore.com>
8926 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
8927 when capturing size information, instead of base type, which for a
8928 formal array type will be the unconstrained type.
8929 (Analyze_Formal_Object_Declaration): Add check for illegal default
8930 expressions for a formal in object of a limited type.
8931 (Instantiate_Object): Ditto.
8932 (Check_Formal_Package_Instance): Skip entities that are formal objects,
8933 because they were defaulted in the formal package and no check applies
8935 (Check_Formal_Package_Instance): Extend conformance check to other
8936 discrete types beyond Integer.
8937 (Process_Default): Copy directly the unmatched formal. A generic copy
8938 has already been performed in Analyze_Formal_Package.
8939 (Analyze_Associations): If a formal subprogram has no match, check for
8940 partial parametrization before looking for a default, to prevent
8942 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
8943 not set the instantiation environment before analyzing the actuals.
8944 Fixes regression on 8515-003 with implementation of AI-133.
8945 Set_Instance_Env checks whether the generic unit is a predefined
8946 unit, in which case the instance must be analyzed with the latest Ada
8947 mode. This setting must take place after analysis of the actuals,
8948 because the actuals must be analyzed and frozen in the Ada mode extant
8949 outside of the current instantiation.
8950 (Save_Env, Restore_Env): Preserve and restore the configuration
8951 parameters so that predefined units can be compiled in the proper Ada
8953 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
8954 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
8955 and Is_Abstract_Type.
8956 (Analyze_Formal_Package): For better error recovery, Add exception
8957 handler to catch Instantion_Error, which can be raised in
8958 Analyze_Associations

8961 Bob Duff <duff@adacore.com>
8962 Gary Dismukes <dismukes@adacore.com>
8964 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
8965 prefix type is a discriminated subtype of the type of the formal.
8966 (Analyze_Allocator): Collect all coextensions regardless of the context.
8967 Whether they can be allocated statically is determined in exp_ch4.
8968 (Analyze_Selected_Component): If the prefix is a limited view and the
8969 non-limited view is available, use the non-limited one.
8970 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
8971 therefore illegal), suggest a qualified expression rather than a type
8972 conversion, because a type conversion would be illegal in this context.
8973 (Anayze_Allocator): Trace recursively all nested allocators so that all
8974 coextensions are on the corresponding list for the root. Do no mark
8975 coextensions if the root allocator is within a declaration for a stack-
8976 allocated object, because the access discriminants will be allocated on
8978 (Analyze_Call): Remove restriction on calls to limited functions for the
8979 cases of generic actuals for formal objects, defaults for formal objects
8980 and defaults for record components.
8981 (Analyze_Allocator): Before analysis, chain coextensions on the proper
8982 element list. Their expansion is delayed until the enclosing allocator
8983 is processed and its finalization list constructed.
8984 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
8985 for an operation with the given name among the primitive operations of
8986 the corresponding record type.
8987 (Analyze_Selected_Component): If the prefix is a task type that
8988 implements an interface, and there is no entry with the given name,
8989 check whether there is another primitive operation (e.g. a function)
8991 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
8992 properly the indexing of a function call written in prefix form, where
8993 the function returns an array type, and all parameters of the function
8994 except the first have defaults.
8995 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
8996 the original operands, rather than relocating them, for efficiency and
8997 to work properly when an operand is overloaded.
8998 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
8999 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
9000 (Analyze_Selected_Component): If the prefix is a private extension, only
9001 scan the visible components, not those of the full view.
9002 (Try_Primitive_Operation): If the operation is a procedure, collect all
9003 possible interpretations, as for a function, because in the presence of
9004 classwide parameters several primitive operations of the type can match
9005 the given arguments.
9007 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9008 Robert Dewar <dewar@adacore.com>
9010 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a

9013 (Analyze_Loop_Statement): Improve detection of infinite loops
9015 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9016 Thomas Quinot <quinot@adacore.com>
9018 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
9019 out of Analyze_Package_Declaration, because processing must be applied
9020 to package bodies as well, for deferred constants completed by pragmas.
9021 (Analyze_Package_Declaration): When the package declaration being
9022 analyzed does not require an explicit body, call Check_Completion.
9023 (May_Need_Implicit_Body): An implicit body is required when a package
9024 spec contains the declaration of a remote access-to-classwide type.
9025 (Analyze_Package_Body): If the package contains RACWs, append the
9026 pending subprogram bodies generated by exp_dist at the end of the body.
9027 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
9028 Is_Abstract_Subprogram and Is_Abstract_Type.
9029 (Preserve_Full_Attributes): The full entity list is not an attribute
9030 that must be preserved from full to partial view.
9032 * sem_dist.adb (Add_RAS_Dereference_TSS):
9033 Change primitive name to _Call so it cannot clash with any legal
9034 identifier, and be special-cased in Check_Completion.
9035 Mark the full view of the designated type for the RACW associated with
9036 a RAS as Comes_From_Source to get proper view switching when installing
9037 private declarations.
9038 Provite a placeholder nested package body along with the nested spec
9039 to have a place for Append_RACW_Bodies to generate the calling stubs
9040 and stream attributes.
9042 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9043 Robert Dewar <dewar@adacore.com>
9045 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
9046 that is a limited view, check the non-limited view if available.
9047 (Undefined): Refine error message for missing with of Text_IO
9048 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
9049 to distinguish real missing with cases.
9050 Fix format of all missing with messages
9051 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
9052 renaming as body when renamed entity is abstract.
9054 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9055 Javier Miranda <miranda@adacore.com>
9057 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
9058 predicate recursive, to handle complex expressions on literals whose
9059 spurious ambiguity comes from the abstract interpretation of some
9061 (Interface_Present_In_Ancestor): Add support to concurrent record
9063 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
9064 Is_Abstract_Subprogram and Is_Abstract_Type.
9066 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9067 Javier Miranda <miranda@adacore.com>
9069 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
9070 dereference of a local object R created as a reference to another
9071 object O, use the access level of O.
9072 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
9073 rather than local Same_Formal_Type, to check whether protected operation
9074 overrides an inherited one.
9075 (Same_Formal_Type): New predicate, used when matching signatures of
9076 overriding synchronized operations, to handle the case when a formal
9077 has a type that is a generic actual.
9078 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
9079 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
9080 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
9081 syntactic ambiguities involving indexing of function calls that return
9083 (Abstract_Interface_List): New subprogram that returns the list of
9084 abstract interfaces associated with a concurrent type or a
9085 concurrent record type.
9086 (Interface_Present_In_Parent): New subprogram used to check if a
9087 given type or some of its parents implement a given interface.
9088 (Collect_Abstract_Interfaces): Add support for concurrent types
9089 with interface types.
9090 (Has_Abstract_Interfaces): Add support for concurrent types with
9092 (Is_Parent): New subprogram that determines whether E1 is a parent
9093 of E2. For a concurrent type its parent is the first element of its
9094 list of interface types; for other types this function provides the
9095 same result than Is_Ancestor.
9096 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
9097 (Collect_Synchronized_Interfaces): Removed because the subprogram
9098 Collect_Abstract_Interfaces provides this functionality.
9099 (Collect_Abstract_Interfaces): Minor update to give support to
9100 concurrent types and thus avoid undesired code duplication.
9101 (Get_Subprogram_Entity): Handle entry calls.
9102 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
9104 (Enter_Name): Do not give -gnatwh hiding warning for record component
9105 entities, they never result in hiding.
9107 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9108 Robert Dewar <dewar@adacore.com>
9110 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
9111 to chain nested components that are allocators for access discriminants
9112 of the enclosing object.
9113 Add N_Push and N_Pop nodes
9114 New field Exception_Label added
9115 (Local_Raise_Statements): New field in N_Exception_Handler_Node
9116 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node
9117 (Is_Coextension): New flag for allocators, to mark allocators that
9118 correspond to access discriminants of dynamically allocated objects.

9435 anonymous access types.
9436 (Valid_Conversion): For a conversion to a numeric type occurring in an

9723 the alignment of the field type.
9724 (make_dummy_type): Use the Non_Limited_View as the underlying type if
9725 the type comes from a limited_with clause. Do not loop on the full view.

10144 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
10145 are build-in-place function calls.
10146 (Replace_Self_Reference): New subsidiary of
10147 Make_OK_Assignment_Statement, to replace an access attribute that is a
10148 self-reference into an access to the appropriate component of the
10149 target object. Generalizes previous mechanism to handle self-references
10150 nested at any level.
10151 (Is_Self_Referential_Init): Remove, not needed.
10152 (Is_Self_Referential_Init): New predicate to simplify handling of self
10153 referential components in record aggregates.

10155 check for presence of entity before checking for self-reference.
10156 (Has_Default_Init_Comps): Return True if a component association is a
10157 self-reference to the enclosing type, which can only come from a
10158 default initialization.
10159 (Make_OK_Assignment_Statement): If the expression is of the form
10160 Typ'Acc, where Acc is an access attribute, the expression comes from a
10161 default initialized self-referential component.
10162 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
10163 that has been derived from several abstract interfaces we must also
10164 initialize the tags of the secondary dispatch tables.

10169 Robert Dewar <dewar@adacore.com>
10172 (Expand_Access_To_Protected_Op): If the context indicates that an access
10173 to a local operation may be transfered outside of the object, create an
10174 access to the wrapper operation that must be used in an external call.
10175 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
10176 target, pass the Valid attribute applied to a floating-point prefix on
10177 to the back end without expansion.
10178 (Storage_Size): Use the new run-time function Storage_Size to retrieve
10179 the allocated storage when it is specified by a per-object expression.
10180 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
10181 Nothing to do here, the attribute has been rewritten during semantic

10190 into a fat pointer.
10191 (Is_Constrained_Aliased_View): New predicate to help determine whether a
10192 subcomponent's enclosing variable is aliased with a constrained subtype.
10193 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
10194 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
10195 an aliased prefix must be known to be constrained in order to use True
10196 for the attribute value, and now it's possible for some aliased views
10197 to be unconstrained.
10199 2006-10-31 Robert Dewar <dewar@adacore.com>
10201 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
10202 (Expand_Entity_Reference): Correct error of not handling subprogram
10203 formals in current_value processing.
10205 2006-10-31 Javier Miranda <miranda@adacore.com>

10210 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
10211 register in the final list objects containing class-wide interfaces;
10212 otherwise we incorrectly register the tag of the interface in the final
10214 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
10215 generate the wrapper if the parent primitive is abstract. This is
10216 required to report the correct error message.
10217 (Expand_N_Subtype_Indication): Do validity checks on range
10218 (Clean_Task_Names): If an initialization procedure includes a call to
10219 initialize a task (sub)component, indicate that the procedure will use
10220 the secondary stack.
10221 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
10222 compatibility for interfacing with CPP by default.
10223 (Expand_N_Object_Declaration): Only build an Adjust call when the
10224 object's type is a nonlimited controlled type.
10225 * exp_ch3.adb: Add with and use of Exp_Ch6.
10226 (Expand_N_Object_Declaration): Check for object initialization that is a
10227 call to build-in-place function and apply Make_Build_In_Place_Call_In_
10228 Object_Declaration to the call.
10229 (Freeze_Type): When the designated type of an RACW was not frozen at the
10230 point where the RACW was declared, validate the primitive operations
10231 with respect to E.2.2(14) when it finally is frozen.
10232 (Build_Initialization_Call,Expand_Record_Controller): Rename
10233 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
10234 return-by-reference has no meaning in Ada 2005.
10235 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
10236 to register tag of the immediate ancestor interfaces in the
10237 run-time structure.
10238 (Init_Secondary_Tags): Moved to the specification to allow the
10239 initialization of extension aggregates with abstract interfaces.
10240 (Build_Master_Renaming): Make public, for use by function declarations
10241 whose return type is an anonymous access type.
10242 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
10243 Insert_List_Before_And_Analyze after the generation of the specs
10244 associated with null procedures.
10245 (Expand_Tagged_Root): Update documentation in its specification.
10246 (Init_Secondary_Tags): Update documentation.
10247 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
10248 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
10249 then generate code to inherit the contents of the dispatch table
10250 directly from the ancestor.
10251 (Expand_Record_Controller): Insert controller component after tags of
10252 implemented interfaces.
10253 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
10254 create null procedure overridings when null procedures are inherited
10256 (Make_Null_Procedure_Specs): New procedure to generate null procedure
10257 declarations for overriding null primitives inherited from interfaces.
10258 (Is_Null_Interface_Procedure): New function in
10259 Make_Null_Procedure_Specs.
10260 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
10261 immediate ancestor of a tagged type is an abstract interface type we
10262 must generate the specification of the predefined primitives associated
10263 with controlled types (because the dispatch table of the ancestor is
10264 null and hence these entries cannot be inherited). This is required to
10265 elaborate well the dispatch table.

10275 (Expand_N_In): Do validity checks on range
10276 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
10277 (Expand_N_Allocator): For "new T", if the object is constrained by
10278 discriminant defaults, allocate the right amount of memory, rather than
10279 the maximum for type T.
10280 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
10281 when the allocator is initialized by a build-in-place call, since the
10282 allocator is already rewritten as a reference to the function result,
10283 and this prevents an unwanted duplication of the function call.
10284 Add with and use of Exp_Ch6.
10285 (Expand_Allocator_Expresssion): Check for an allocator whose expression
10286 is a call to build-in-place function and apply
10287 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
10288 untagged designated types).
10289 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
10290 optimization if source or target is biased.
10291 (Expand_N_Allocator): Add comments for case of an allocator within a
10292 function that returns an anonymous access type designating tasks.
10293 (Expand_N_Allocator): apply discriminant checks for access
10294 discriminants of anonymous access types (AI-402, AI-416)

10303 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
10304 (Expand_N_Assignment_Statement): Call
10305 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
10306 build-in-place function call. Currently, this can happen only for
10307 assignments that come from aggregates.
10308 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
10309 in order to alleviate the upward compatibility introduced by AI-318.
10310 (Expand_N_Extended_Return_Statement): Add support for handling the
10311 return object as a build-in-place result.
10312 (Expand_Non_Function_Return): Implement simple return statements nested
10313 within an extended return.
10314 (Enable_New_Return_Processing): Turn on the new processing of return
10316 (Expand_Non_Function_Return): For a return within an extended return,
10317 don't raise Program_Error, because Sem_Ch6 now gives a warning.
10318 (Expand_N_Extended_Return_Statement): Implement AI-318
10319 (Expand_Simple_Function_Return): Ditto.
10320 (Expand_N_If_Statement): Handle new -gnatwt warning

10322 (Expand_N_Assignment): Handle assignment to the Priority attribute of
10323 a protected object.
10324 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
10325 validity checking of assignments to elementary record components.
10326 (Expand_N_Return_Statement): return Class Wide types on the secondary
10327 stack independantly of their controlled status since with HIE runtimes,
10328 class wide types are not potentially controlled anymore.
10330 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
10333 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
10334 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
10335 it expects a block, procedure, or task. The return statement will get
10336 turned into a block, and Expand_Cleanup_Actions will happen then.

10340 Bob Duff <duff@adacore.com>
10341 Gary Dismukes <dismukes@adacore.com>
10343 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
10345 (Expand_Inlined_Call): Tagged types are by-reference types, and
10346 therefore should be replaced by a renaming declaration in the expanded
10347 body, as is done for limited types.
10348 (Expand_Call): If this is a call to a function with dispatching access
10349 result, propagate tag from context.
10350 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
10352 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
10353 build-in-place when the right-hand side of an assignment is a
10354 build-in-place function call.
10355 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
10356 of the explicit dereference of the allocator to the result subtype of
10357 the build-in-place function. This is needed to satisfy type checking
10358 in cases where the caller's return object is created by an allocator for
10359 a class-wide access type and the type named in the allocator is a
10361 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
10362 conversion of the reference to the declared object to the result subtype
10363 of the build-in-place function. This is needed to satisfy type checking
10364 in cases where the declared object has a class-wide type. Also, in the
10365 class-wide case, change the type of the object entity to the specific
10366 result subtype of the function, to avoid passing a class-wide object
10367 without explicit initialization to the back end.
10368 (Register_Interface_DT_Entry): Moved outside the body of
10369 Freeze_Subprogram because this routine is now public; it is called from
10370 Check_Dispatching_Overriding to handle late overriding of abstract
10371 interface primitives.
10372 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
10373 adding an implicit access actual on a call to a build-in-place function.
10374 (Expand_Actuals): Test for an actual parameter that is a call to a
10375 build-in-place function and apply
10376 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
10377 (Is_Build_In_Place_Function): New function to determine whether an
10378 entity is a function whose calls should be handled as build-in-place.
10379 (Is_Build_In_Place_Function_Call): New function to determine whether an
10380 expression is a function call that should handled as build-in-place.
10381 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
10382 calls to build-in-place functions as the initialization of an allocator.
10383 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
10384 handling calls to build-in-place functions in contexts that do not
10385 involve init of a separate object (for example, actuals of subprogram
10387 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
10388 handling calls to build-in-place functions as the initialization of an
10389 object declaration.

10391 instantiation of Traverse_Body to avoid unreferenced warning.
10392 (Check_Overriding_Inherited_Interfaces): Removed.
10393 (Register_Interface_DT_Entry): Code cleanup.
10394 (Register_Predefined_DT_Entry): Code cleanup.
10395 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
10396 inlined statements if within a transient scope.
10397 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
10398 formal parameters with occurrences of actuals in inlined body, establish
10399 visibility on the proper view of the actual's subtype for the body's
10401 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
10402 compatibility mode and we have an imported CPP subprogram because
10403 for now we assume that imported CPP primitives correspond with
10404 objects whose constructor is in the CPP side (and therefore we
10405 don't need to generate code to register them in the dispatch table).
10406 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
10407 aligned selected component.
10408 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
10409 the actual of an in-mode parameter is a type conversion.
10410 (Expand_Actuals): If the call does not come from source and the actual
10411 is potentially misaligned, let gigi handle it rather than rejecting the
10412 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
10413 Class Wide types as returning by reference independantly of their
10414 controlled status since with HIE runtimes class wide types are not
10415 potentially controlled anymore.

10419 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
10420 references that are private components of the protected object.

10422 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
10423 instantiation to deal with warnings.

10430 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
10431 initialization of Homonym_Len.
10432 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
10433 names from fully qualified name. Fixes problem of duplicate
10434 external names differing only in the presence of such a block name.
10436 2006-10-31 Thomas Quinot <quinot@adacore.com>
10437 Pablo Oliveira <oliveira@adacore.com>
10439 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
10440 subprogram Ids, even if they are not yet assigned.
10441 (Build_Subprogram_Id): It is now this function that will take care of
10442 calling Assign_Subprogram_Ids if necessary.
10443 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
10444 should be done only once they are assigned.
10445 (Build_From_Any_Function, case of tagged types): Add missing call to

10448 type for an RACW type.
10449 (Add_RACW_Features): When processing an RACW declaration for which the
10450 designated type is already frozen, enforce E.2.2(14) rules immediately.
10451 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
10452 special reordering of controlling formals.
10454 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the

10457 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10459 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
10460 fixed-point operations in an integer context, i.e. as operands of a
10461 conversion to an integer type, indicate that result must be rounded.
10463 2006-10-31 Robert Dewar <dewar@adacore.com>
10465 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
10466 cases, pass the encoding method, since it is now required by the run
10469 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
10470 assumption that Str'First = 1.
10471 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
10472 it on to the Value_Wide_Wide_Character call.
10473 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
10474 properly handles a string of the form quote-encoded_wide_char-quote.

10482 implements the target abstract interface.
10484 2006-10-31 Robert Dewar <dewar@adacore.com>
10486 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
10487 Machine_Attribute pragma internally to implement the user pragma.
10488 Add processing for pragma Interface so that it is now completely
10489 equivalent to pragma Import.
10491 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
10492 so that it can be applied to all entities, including record components
10493 and enumeration literals.
10494 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
10495 priority ranges are correct, verify compatibility against task
10496 dispatching and locking policies, and if everything is correct an entry
10497 is added to the table containing priority specific dispatching entries
10498 for this compilation unit.
10499 (Delay_Config_Pragma_Analyze): Delay processing
10500 Priority_Specific_Dispatching pragmas because when processing the
10501 pragma we need to access run-time data, such as the range of
10502 System.Any_Priority.
10503 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
10504 Allow pragma Unreferenced as a context item
10505 Add pragma Preelaborable_Initialization
10506 (Analyze_Pragma, case Interface): Interface is extended so that it is
10507 now syntactically and semantically equivalent to Import.
10508 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
10509 insertion characters.
10510 Add handling for Pragma_Wide_Character_Encoding
10511 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
10512 never supercedes a real restriction, and that a real restriction
10513 always supercedes a warning.
10514 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
10517 2006-10-31 Bob Duff <duff@adacore.com>
10518 Ed Schonberg <schonberg@adacore.com>
10519 Robert Dewar <dewar@adacore.com>
10521 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
10522 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
10523 Is_Inherently_Limited_Type, because return-by-reference has no meaning
10525 (Find_Node_To_Be_Wrapped): Use new method of determining the result
10526 type of the function containing a return statement, because the
10527 Return_Type field was removed. We now use the Return_Applies_To field.
10529 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
10530 (Build_Task_Image_Decl): If procedure is not called from an
10531 initialization procedure, indicate that function that builds task name
10532 uses the sec. stack. Otherwise the enclosing initialization procedure
10533 will carry the indication.
10534 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
10535 N_Object_Declaration instead.
10536 (Kill_Dead_Code): New interface to implement -gnatwt warning for
10537 conditional dead code killed, and change implementation accordingly.
10538 (Insert_Actions): Add N_Return_Object_Declaration case.
10539 Correct comment to mention N_Extension_Aggregate node.
10540 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
10541 attempts to save information for global variables which cannot be
10543 (Get_Current_Value_Condition): Handle conditions the other way round
10544 (constant on left). Also handle right operand of AND and AND THEN
10545 (Set_Current_Value_Condition): Corresponding changes
10546 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
10547 (Get_Current_Value_Condition): Handle simple boolean operands
10548 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
10549 (Get_Current_Value_Condition): If the variable reference is within an
10550 if-statement, does not appear in the list of then_statments, and does
10551 not come from source, treat it as being at unknown location.
10552 (Get_Current_Value_Condition): Enhance to allow while statements to be
10553 processed as well as if statements.
10554 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
10556 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
10557 of loop. This is safe now that we fixed Kill_Current_Values.
10558 (OK_To_Do_Constant_Replacement): Check whether current scope is
10559 Standard, before examining outer scopes.
10561 2006-10-31 Vincent Celier <celier@adacore.com>
10563 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
10564 When True, apply VMS treatment to children of packages A, G, I and S.
10567 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
10569 2006-10-31 Robert Dewar <dewar@adacore.com>
10570 Ed Schonberg <schonberg@adacore.com>
10572 * freeze.adb: Add handling of Last_Assignment field
10573 (Warn_Overlay): Supply missing continuation marks in error msgs
10574 (Freeze_Entity): Add check for Preelaborable_Initialization
10576 * g-comlin.adb: Add Warnings (Off) to prevent new warning
10578 * g-expect.adb: Add Warnings (Off) to prevent new warning
10580 * lib-xref.adb: Add handling of Last_Assignment field
10581 (Generate_Reference): Centralize handling of pragma Obsolescent here
10582 (Generate_Reference): Accept an implicit reference generated for a
10583 default in an instance.
10584 (Generate_Reference): Accept a reference for a node that is not in the
10585 main unit, if it is the generic body corresponding to an subprogram
10588 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
10590 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
10592 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
10594 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
10595 use clauses, to avoid messages on packages used to qualify, and also
10596 to avoid messages from obsolescent units.
10597 (Warn_On_Useless_Assignments): Don't generate messages for imported
10598 and exported variables.
10599 (Warn_On_Useless_Assignments): New procedure
10600 (Output_Obsolescent_Entity_Warnings): New procedure
10601 (Check_Code_Statement): New procedure
10603 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
10604 Change name Is_Ada_2005 to Is_Ada_2005_Only
10605 (Last_Assignment): New field for useless assignment warning
10607 2006-10-31 Olivier Hainque <hainque@adacore.com>
10609 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
10610 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
10612 2006-10-31 Bob Duff <duff@adacore.com>
10613 Robert Dewar <dewar@adacore.com>
10614 Ed Schonberg <schonberg@adacore.com>
10616 * g-awk.adb (Default_Session, Current_Session): Compile this file in
10617 Ada 95 mode, because it violates the new rules for AI-318.
10619 * g-awk.ads: Use overloaded subprograms in every case where we used to
10620 have a default of Current_Session. This makes the code closer to be
10621 correct for both Ada 95 and 2005.
10623 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
10624 code, relying on the fact that the compiler generates a warning
10625 instead of an error in -gnatg mode.
10627 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
10628 E_Return_Statement entity kind.
10629 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
10631 * par.adb (P_Interface_Type_Definition): Addition of one formal to
10632 report an error if the reserved word abstract has been previously found.
10633 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
10635 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
10636 parenthesized range attribute usage
10637 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
10639 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
10640 in the syntax for extended_return_statement. This is not in the latest
10641 RM, but the ARG is expected to issue an AI allowing this.
10642 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
10643 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
10644 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
10645 P_Return_Statement): Parse the new syntax for extended_return_statement.
10647 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
10648 Output_End_Missing): Add error-recovery code for the new
10649 extended_return_statement syntax; that is, the new E_Return entry on
10652 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
10653 limited to nonlimited, because otherwise we violate the new Ada 2005
10654 rules about returning limited types in function Create_AST_Handler in
10657 * sem.adb (Analyze): Add cases for new node kinds
10658 N_Extended_Return_Statement and N_Return_Object_Declaration.
10660 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
10661 type is in the same category as type of context before applying check,
10662 to prevent anomalies in instantiations.
10663 (Resolve_Aggregate): Remove test for limited components in aggregates.
10664 It's unnecessary in Ada 95, because if it has limited components, then
10665 it must be limited. It's wrong in Ada 2005, because limited aggregates
10667 (Resolve_Record_Aggregate): Move check for limited types later, because
10668 OK_For_Limited_Init requires its argument to have been resolved.
10669 (Get_Value): When copying the component default expression for a
10670 defaulted association in an aggregate, use the sloc of the aggregate
10671 and not that of the original expression, to prevent spurious
10672 elaboration errors, when the expression includes function calls.
10673 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
10674 were missing. We also didn't handle qualified expressions. Now also
10675 allow function calls. Use new common routine OK_For_Limited_Init.
10676 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
10677 with space can upper case letter).
10679 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
10680 Has_Static_Discriminants flag
10681 (Record_Type_Declaration): Diagnose an attempt to declare an interface
10682 type with discriminants.
10683 (Process_Range_Expr_In_Decl): Do validity checks on range
10684 (Build_Discriminant_Constraints): Use updated form of
10685 Denotes_Discriminant.
10686 (Process_Subtype): If the subtype is a private subtype whose full view
10687 is a concurrent subtype, introduce an itype reference to prevent scope
10689 (Build_Derived_Record_Type, Collect_Interface_Primitives,
10690 Record_Type_Declaration): The functionality of the subprograms
10691 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
10692 is now performed by a single routine.
10693 (Build_Derived_Record_Type): If the type definition includes an explicit
10694 indication of limitedness, then the type must be marked as limited here
10695 to ensure that any access discriminants will not be treated as having
10696 a local anonymous access type.
10697 (Check_Abstract_Overriding): Issue a detailed error message when an
10698 abstract subprogram was not overridden due to incorrect mode of its
10700 (Analyze_Private_Extension_Declaration): Add support for the analysis of
10701 synchronized private extension declarations. Verify that the ancestor is
10702 a limited or synchronized interface or in the generic case, the ancestor
10703 is a tagged limited type or synchronized interface and all progenitors
10704 are either limited or synchronized interfaces.
10705 Derived_Type_Declaration): Check for presence of private extension when
10706 dealing with synchronized formal derived types.
10707 Process_Full_View): Enchance the check done on the usage of "limited" by
10708 testing whether the private view is synchronized.
10709 Verify that a synchronized private view is completed by a protected or
10711 (OK_For_Limited_Init_In_05): New function.
10712 (Analyze_Object_Declaration): Move check for limited types later,
10713 because OK_For_Limited_Init requires its argument to have been resolved.
10714 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
10715 in order to alleviate the upward compatibility introduced by AI-318.
10716 (Constrain_Corresponding_Record): If the constraint is for a component
10717 subtype, mark the itype as frozen, to avoid out-of-scope references to
10718 discriminants in the back-end.
10719 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
10720 this subprogram against wrong sources.
10721 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
10722 discriminant of limited type completed with a protected type, when the
10723 discriminant is used to constrain a private component of the type, and
10724 expansion is disabled.
10725 (Find_Type_Of_Object): Do not treat a return subtype that is an
10726 anonymous subtype as a local_anonymous_type, because its accessibility
10727 level is the return type of the enclosing function.
10728 (Check_Initialization): In -gnatg mode, turn the error "cannot
10729 initialize entities of limited type" into a warning.
10730 (OK_For_Limited_Init): Return true for generated nodes, since it
10731 sometimes violates the legality rules.
10732 (Make_Incomplete_Declaration): If the type for which an incomplete
10733 declaration is created happens to be the currently visible entity,
10734 preserve the homonym chain when removing it from visibility.
10735 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
10736 inherited subprograms.
10737 (Access_Definition): If this is an access to function that is the return
10738 type of an access_to_function definition, context is a type declaration
10739 and the scope of the anonymous type is the current one.
10740 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
10741 incomplete subtype to the set of private dependents of the original
10743 (Constrain_Discriminated_Type): Emit an error message whenever an
10744 incomplete subtype is being constrained.
10745 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
10746 corresponding subtype of the full view of the original incomplete type.
10747 (Check_Incomplete): Properly detect invalid usage of incomplete types
10750 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
10752 * g-catiio.ads, g-catiio.adb (Value): New function.

10761 Robert Dewar <dewar@adacore.com>
10763 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
10764 handling executable extension manually and duplicating code.
10766 * make.adb: Implement new -S switch
10767 (Gnatmake): Use new function Osint.Executable_Name instead
10768 of handling executable extension manually.
10770 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
10771 is specified, the executable name ends with this suffix.
10772 Take advantage of Osint.Executable_Name instead of duplicating code.
10774 * switch-m.adb: Recognize new gnatmake -S switch
10776 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
10778 (Get_Target_Parameters): Set Executable_Extension_On_Target if
10781 * makeusg.adb: Add line for gnatmake -S switch
10783 2006-10-31 Vincent Celier <celier@adacore.com>
10785 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
10786 call it with -static-libgcc, as there are some platforms, such as
10787 Darwin, where one of these two switches is compulsory to link.
10789 2006-10-31 Vincent Celier <celier@adacore.com>
10791 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
10792 instead of ADA_PROJECT_PATH, for the project path.
10793 (Gnatls): When displaying the project path directories, use host dir
10796 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
10797 names in the project path, as absolute paths may correspond to
10798 multi-valued VMS logical names.
10800 2006-10-31 Vincent Celier <celier@adacore.com>
10802 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
10803 absolute path name.
10804 (Locate_Regular_File): Ditto
10805 (Change_Dir): Remove, no longer used
10806 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
10807 on Windows. Get it calling Get_Current_Dir.
10808 (OpenVMS): Remove imported boolean, no longer needed.
10809 (Normalize_Pathname)[VMS]: Do not resolve directory names.
10810 (Pid_To_Integer): New function to convert a Process_Id to Integer
10812 2006-10-31 Thomas Quinot <quinot@adacore.com>
10814 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
10815 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
10817 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
10820 2006-10-31 Robert Dewar <dewar@adacore.com>
10822 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
10823 initial letter o as a zero.

10827 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
10829 2006-10-31 Robert Dewar <dewar@adacore.com>
10831 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
10833 (Layout_Variant_Record): Retrieve the discriminants from the entity
10834 rather than from the type definition, because in the case of a full
10835 type for a private type we need to take the discriminants from the
10837 (Layout_Component_List): When applying the Max operator to variants with
10838 a nonstatic size, check whether either operand is static and scale that
10839 operand from bits to storage units before applying Max.
10840 (Layout_Type): In VMS, if a C-convention access type has no explicit
10841 size clause (and does not inherit one in the case of a derived type),
10842 then the size is reset to 32 from 64.
10844 2006-10-31 Vincent Celier <celier@adacore.com>
10846 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
10847 its file has already been loaded, according to the unit being loaded,
10848 not to the current value of Multiple_Unit_Index.
10850 2006-10-31 Thomas Quinot <quinot@adacore.com>
10851 Eric Botcazou <ebotcazou@adacore.com>
10852 Arnaud Charlet <charlet@adacore.com>
10854 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
10855 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
10857 (a-except.o): Pass it to the compiler.
10858 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
10859 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
10860 a-calend-mingw.adb version.
10862 * Makefile.rtl: Added s-dsaser.
10863 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
10864 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
10865 Ada.Dispatching.Round_Robin.
10866 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
10868 * Make-lang.in: Remove all references to gt-ada-decl.h.
10869 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
10871 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
10872 Update dependencies.

10876 2006-10-31 Vincent Celier <celier@adacore.com>
10878 * mlib-utl.adb (Initialized): Remove, no longer used
10879 (Initialize): Remove, no longer used
10880 (Ar): If Ar_Exec is null, get the location of the archive builder and,
10881 if there is one, the archive indexer. Fail if the archive builder cannot
10883 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
10886 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10888 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
10889 Process_Body_Clauses): If the context of a body includes a use clause
10890 for P.Q then a with_clause for P in the same body is not redundant,
10891 even if the spec also has a with_clause on P.
10892 Add missing continuation mark to error msg
10893 (Build_Limited_Views): A limited view of a type is tagged if its
10894 declaration includes a record extension.
10895 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
10896 node, even if the subunit has errors. This avoids malfunction by
10897 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
10898 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
10899 generation of obsolescent messages for with statements (cannot do
10900 this too early, or we cannot implement avoiding the messages in the
10901 case of obsolescent units withing obsolescent units).
10902 (Install_Siblings): If the with_clause is on a remote descendant of
10903 an ancestor of the current compilation unit, find whether there is
10904 a sibling child unit that is immediately visible.
10905 (Remove_Private_With_Clauses): New procedure, invoked after completing
10906 the analysis of the private part of a nested package, to remove from
10907 visibility the private with_clauses of the enclosing package
10909 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
10910 now centralized in Generate_Reference.
10911 (Install_Limited_Context_Clauses): Remove superfluous error
10912 message associated with unlimited view visible through use
10913 and renamings. In addition, at the point in which the error
10914 is reported, we add the backslash to the text of the error
10915 to ensure that it is reported as a single error message.
10916 Use new // insertion for some continuation messages
10917 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
10918 to create implicit with_clause for parent unit mentioned in original
10919 limited_with_clause.
10920 (Install_Limited_With_Unit): Set entity of parent identifiers if the
10921 unit is a child unit. For ASIS queries.
10922 (Analyze_Subunit): If the subunit appears within a child unit, make all
10923 ancestor child units directly visible again.
10925 2006-10-31 Robert Dewar <dewar@adacore.com>

10935 Add the new actual Abstract_Present to every call to
10936 P_Interface_Type_Definition.
10937 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
10938 a formal object declaration with an access definition or a subtype mark
10939 with a null exclusion.
10940 (P_Generic_Association): Handle association with box, and others_choice
10941 with box, to support Ada 2005 partially parametrized formal packages.

10944 Javier Miranda <miranda@adacore.com>
10946 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
10947 (P_Type_Declaration): Remove barrier against the reserved word "limited"
10948 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).

10950 private extensions.
10951 (P_Type_Declaration): Add the new actual Abstract_Present to every call
10952 to P_Interface_Type_Definition.
10953 (P_Interface_Type_Definition): Addition of one formal to report an error
10954 if the reserved word abstract has been previously found.
10955 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
10956 object renaming declaration with an access definition or subtype mark
10957 with a possible null exclusion.

10981 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
10982 on VMS, change "__" to '.' before checking the name.

10984 of sources, even if it is not the first time, as it is for another
10986 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
10987 dot, instead of replacing only the first '_'.
10989 * prj-part.adb (Parse): Convert project file path to canonical form
10991 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
10992 extended, the project id of the project extending it is recorded in its
10993 data, even when it has already been processed as an imported project.
10995 2006-10-31 Robert Dewar <dewar@adacore.com>

11001 Robert Dewar <dewar@adacore.com>
11003 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
11004 only a restriction warning is active for the given restriction. This is
11005 desirable because we do not want to modify code in the case where only
11007 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
11008 causes overriding of real restrictions.
11009 Take advantage of new No_Restrictions constant.
11011 * raise.h: (__gnat_set_globals): Change profile.
11013 2006-10-31 Arnaud Charlet <charlet@adacore.com>
11015 * rtsfind.adb: Remove s-polint from comment as it exists no more.
11018 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
11019 Move all the entities in obsolete package System.PolyORB_Interface to
11020 System.Partition_Interface.
11021 (RE_Storage_Size): New function in System.Tasking.

11038 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
11039 properly an attempt to apply Unchecked_Access to a protected operation.
11040 (OK_Self_Reference): New subprogram to check the legality of an access
11041 attribute whose prefix is the type of an enclosing aggregate.
11042 Generalizes previous mechanism to handle attribute references nested
11043 arbitrarily deep within the aggregate.
11044 (Analyze_Access_Attribute): An access attribute whose prefix is a type
11045 can appear in an aggregate if this is a default-initialized aggregate
11046 for a self-referential type.
11047 (Resolve_Attribute, case Access): Ditto.
11048 Add support for new implementation defined attribute Stub_Type.

11050 (Analyze_Attribute, case Attribute_Stub_Type): New case.
11051 (Stream_Attribute_Available): Implement using new subprogram from
11052 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
11053 Has_Specified_Stream_Attribute flag.
11054 Disallow Storage_Size and Storage_Pool for access to subprogram
11055 (Resolve_Attribute, case 'Access et al): Take into account anonymous
11056 access types of return subtypes in extended return statements. Remove
11057 accessibility checks on anonymous access types when Unchecked_Access is
11059 (Analyze_Attribute): Add support for the use of 'Class to convert
11060 a class-wide interface to a tagged type.
11061 Add support for the attribute Priority.
11062 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
11063 whether the designated type is discriminated with a constrained partial
11064 view and require static matching in that case.
11065 Add local variable Des_Btyp. The Designated_Type
11066 of an access to incomplete subtype is either its non-limited view if
11067 coming from a limited with or its etype if regular incomplete subtype.
11069 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
11070 Fix predicate to identify and allow cases of (expander-generated)
11071 references to tag of designated object of a RACW.
11072 (Validate_Static_Object_Name): In Ada 2005, a formal object is
11073 non-static, and therefore cannot appear as a primary in a preelaborable
11075 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
11076 Has_Read_Write_Attributes.
11077 (Has_Read_Write_Attributes): Reimplement in termes of
11078 Has_Stream_Attribute_Definition.
11079 (Missing_Read_Write_Attributes): When checking component types in a
11080 record, unconditionally call Missing_Read_Write_Attributes recursively
11081 (remove guard checking for Is_Record_Type / Is_Access_Type).
11083 2006-10-31 Robert Dewar <dewar@adacore.com>
11085 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
11086 useless assignments here and conditionalize it on absence of exception
11088 (Analyze_Exception_Handlers): Small code reorganization of error
11089 detection code, for new handling of formal packages.
11091 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11092 Hristian Kirtchev <kirtchev@adacore.com>
11094 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
11095 that has been constant-folded, preserve information of original tree,
11097 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
11098 generated private extension declaration if the formal derived type is
11099 synchronized. Carry synchronized present over to the generated private
11101 (Validate_Derived_Type_Instance): Ensure that the actual of a
11102 synchronized formal derived type is a synchronized tagged type.
11103 (Instantiate_Formal_Package): When creating the instantiation used to
11104 validate the actual package of a formal declared without a box, check
11105 whether the formal itself depends on a prior actual.
11106 (Instantiate_Formal_Subprogram): Create new entities for the defining
11107 identifiers of the formals in the renaming declaration, for ASIS use.
11108 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
11109 a renaming declaration or a subtype declaration for an actual in an
11110 instance, capture location information of declaration in generic, for
11112 (Instantiate_Formal_Package): Add comments on needed additional tests.
11113 AI-317 (partial parametrization) is fully implemented.
11114 (Validate_Private_Type_Instance): Add check for actual which
11115 must have preelaborable initialization
11116 Use new // insertion for some continuation messages
11117 (Analyze_Formal_Object_Declaration): Change usage of Expression to
11118 Default_Expression. Add type retrieval when the declaration has an
11119 access definition. Update premature usage of incomplete type check.
11120 (Check_Access_Definition): New subsidiary routine. Check whether the
11121 current compilation version is Ada 05 and the supplied node has an
11123 (Instantiate object): Alphabetize local variables. Handle the creation
11124 of new renaming declarations with respect to the kind of definition
11125 used - either an access definition or a subtype mark. Guard against
11126 unnecessary error message in the context of anonymous access types after
11127 they have been resolved. Add check for required null exclusion in a
11128 formal object declaration.
11129 (Switch_View): A private subtype of a non-private type needs to be
11130 switched (the base type can have been switched without its private
11131 dependents because of the last branch of Check_Private_View.
11132 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
11134 (Instantiate_Type): Emit an error message whenever a class-wide type of
11135 a tagged incomplete type is used as a generic actual.
11136 (Find_Actual_Type): Extend routine to handle a component type in a child
11137 unit that is imported from a formal package in a parent.
11138 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
11139 agree on constrainedness, rather than checking against ultimate ancestor
11140 (Instantiate_Subprogram_Body): Create a cross-reference link to the
11141 generic body, for navigation purposes.
11143 2006-10-31 Robert Dewar <dewar@adacore.com>
11144 Thomas Quinot <quinot@adacore.com>
11146 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
11148 (New_Stream_Subprogram): When processing an attribute definition clause
11149 for a stream-oriented subprogram, record an entity node occurring at
11150 the point of clause to use for checking the visibility of the clause,
11151 as defined by 8.3(23) as amended by AI-195.
11152 (New_Stream_Subprogram): New procedure, factoring behaviour from both
11153 New_Stream_Function and New_Stream_Procedure.
11154 (New_Stream_Function, New_Stream_Procedure): Removed.
11155 (Analyze_Attribute_Definition_Clause, case Address): Check new
11156 Alignment_Check check

11159 Javier Miranda <miranda@adacore.com>
11160 Robert Dewar <dewar@adacore.com>
11162 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
11163 generate the same errors compiling under -gnatc.
11164 (Try_Object_Operation): If no candidate interpretation succeeds, but
11165 there is at least one primitive operation with the right name, report
11166 error in call rather than on a malformed selected component.
11167 (Analyze_Selected_Component): If the prefix is an incomplete type from
11168 a limited view, and the full view is available, use the full view to
11169 determine whether this is a prefixed call to a primitive operation.
11170 (Operator_Check): Verify that a candidate interpretation is a binary
11171 operation before checking the type of its second formal.
11172 (Analyze_Call): Add additional warnings for function call contexts not
11174 (Analyze_Allocator): Move the check for "initialization not allowed for
11175 limited types" after analyzing the expression. This is necessary,
11176 because OK_For_Limited_Init looks at the structure of the expression.
11177 Before analysis, we don't necessarily know what sort of expression it
11178 is. For example, we don't know whether F(X) is a function call or an
11179 indexed component; the former is legal in Ada 2005; the latter is not.
11180 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
11181 were missing. We also didn't handle qualified expressions. Now also
11182 allow function calls. Use new common routine OK_For_Limited_Init.
11183 (Analyze_Type_Conversion): Do not perform some legality checks in an
11184 instance, because the error message will be redundant or spurious.
11185 (Analyze_Overloaded_Selected_Component): Do not do style check when
11186 setting an entity, since we do not know it is the right entity yet.
11187 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
11188 (Analyze_Overloaded_Selected_Component): Same change
11189 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
11190 since regular incomplete subtypes are transformed into corresponding
11191 subtypes of their full views.
11192 (Complete_Object_Operation): Treat name of transformed subprogram call
11193 as coming from source, for browsing purposes.
11194 (Try_Primitive_Operation): If formal is an access parameter, compare
11195 with base type of object to determine whether it is a primitive
11197 (Operator_Check): If no interpretation of the operator matches, check
11198 whether a use clause on any candidate might make the operation legal.
11199 (Try_Class_Wide_Operation): Check whether the first parameter is an
11200 access type whose designated type is class-wide.

11207 warn on infinite loops.
11208 Add \\ to some continuation messages
11209 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
11210 (Process_Bounds): If the bounds are integer literals that result from
11211 constant-folding, and they carry a user-defined type, preserve that type
11212 rather than treating this as an integer range.
11213 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
11214 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
11215 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
11216 left hand side of assignment.
11217 (Analyze_Assignment): Add suport to manage assigments to the attribute
11218 priority of a protected object.
11219 (Check_Possible_Current_Value_Condition): Allow fully qualified names
11220 not just identifiers.
11221 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
11222 or AND THEN for possible tracking.
11223 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
11224 case of while loops so we can track values in the loop body.

11227 Hristian Kirtchev <kirtchev@adacore.com>
11228 Bob Duff <duff@adacore.com>
11230 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
11231 procedure cannot be a protected operation (it is a basic_declaration,
11232 not a subprogram_declaration).
11233 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
11234 Subp. Add logic for entry processing.
11235 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
11236 Determine whether an entry or subprogram of a protected or task type
11237 override an inherited primitive of an implemented interface.
11238 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
11239 Update the actual used in calls to Check_Overriding_Indicator.
11240 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
11241 generate the proper reference to the parent unit, for cross-reference.
11242 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
11244 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
11245 (Add_Extra_Formal): Revise procedure to allow passing in associated
11246 entity, scope, and name suffix, and handle setting of the new
11247 Extra_Formals field.
11248 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
11249 pass new parameters. Add support for adding the new extra access formal
11250 for functions whose calls are treated as build-in-place.
11251 (Analyze_A_Return_Statement): Correct casing in error message.
11252 Move Pop_Scope to after Analyze_Function_Return, because an extended
11253 return statement really is a full-fledged scope. Otherwise, visibility
11254 doesn't work right. Correct use of "\" for continuation messages.
11255 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
11256 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
11257 the node doesn't get properly marked as analyzed.
11258 (Analyze_Subprogram_Body): If subprogram is a function that returns
11259 an anonymous access type that denotes a task, build a Master Entity
11261 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
11262 proper usage of null exclusion in a result definition.
11263 (Process_Formals): Code cleanup and new error message.
11264 (Process_Formals): Detect incorrect application of null exclusion to
11266 (Conforming_Types): Handle conformance between [sub]types and itypes
11267 generated for entities that have null exclusions applied to them.
11268 (Maybe_Primitive_Operation): Add an additional type retrieval when the
11269 base type is an access subtype. This case arrises with null exclusions.
11270 (New_Overloaded_Entity): Do not remove the overriden entity from the
11271 homonym chain if it corresponds with an abstract interface primitive.
11272 (Process_Formals): Replace membership test agains Incomplete_Kind with a
11273 call to the synthesized predicate Is_Incomplete_Type.
11274 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
11276 (Analyze_Subprogram_Declaration): Check that abstract interface
11277 primitives are abstract or null.
11278 (Analyze_Subprogram_Specification): Remove previous check for abstract
11279 interfaces because it was not complete.
11280 (Has_Interface_Formals): Removed.

11283 Javier Miranda <miranda@adacore.com>
11285 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
11286 of Analyze_Package_Body, to create Itype references for anonymous
11287 access types created in the package declaration, whose designated types
11288 may have only a limited view.
11289 (Analyze_Package_Specification): For the private part of a nested
11290 package, install private_with_clauses of enclosing compilation unit if
11291 we are in its visible part.
11292 (Declare_Inherited_Private_Subprograms): Complete barrier
11293 to ensure that the primitive operation has an alias to some parent
11294 primitive. This is now required because, after the changes done for the
11295 implementation of abstract interfaces, the contents of the list of
11296 primitives has entities whose alias attribute references entities of
11297 such list of primitives.
11298 (Analyze_Package_Specification): Simplify code that handles parent units
11299 of instances and formal packages.
11300 (Uninstall_Declarations): Check the convention consistency among
11301 primitive overriding operations of a tagged record type.

11310 expected and found set right)
11311 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
11312 (Analyze_Generic_Renaming): Same fix
11313 (Use_One_Package): Do not take into account the internal entities of
11314 abstract interfaces during the analysis of entities that are marked
11315 as potentially use-visible.
11316 (Find_Type): Handle the case of an attribute reference for
11317 implementation defined attribute Stub_Type (simply let the analysis of
11318 the attribute reference rewrite it).
11319 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
11320 type that appears in a Use_Type clause.
11321 (Analyze_Object_Renaming): Add support for renaming of the Priority
11323 (Find_Type): In Ada 2005, a task type can be used within its own body,
11324 when it appears in an access definition.
11325 (Analyze_Object_Renaming): Remove warning on null_exclusion.
11326 (Analyze_Object_Renaming): Introduce checks for required null exclusion
11327 in a formal object declaration or in a subtype declaration.
11328 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
11329 (Check_Null_Exclusion): New local routine to
11330 Analyze_Subprogram_Renaming. Check whether the formals and return
11331 profile of a renamed subprogram have required null exclusions when
11332 their counterparts of the renaming already impose them.
11333 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
11334 Determine whether an entity is inside a generic scope.
11335 (In_Open_Scope): First pass of documentation update.
11336 (Find_Expanded_Name): Add support for shadow entities associated with
11337 limited withed packages. This is required to handle nested packages.
11338 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
11339 that makes a renaming of a limited withed package illegal.

11345 Check_Overriding_Indicator.
11346 (Analyze_Task_Definition): Ditto.
11347 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
11348 (Check_Overriding_Indicator): To find overridden interface operation,
11349 examine only homonyms that have an explicit subprogram declaration, not
11350 inherited operations created by an unrelated type derivation.
11351 (Check_Overriding_Indicator): When checking for the presence of "null"
11352 in a procedure, ensure that the queried node is a procedure
11354 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
11355 type when the formal is an access to variable.
11356 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
11357 (Analyze_Task_Type): Same addition

11367 inherited from an interface ancestor by another interface in the
11368 context of an instance as 'late'.
11369 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
11370 of a call to a function that dispatches on access result.
11371 (Check_Dispatching_Operation): In case of late overriding of a primitive
11372 that covers abstract interface subprograms we register it in all the
11373 secondary dispatch tables associated with abstract interfaces.
11374 (Check_Dispatching_Call): Add check that a dispatching call is not made
11375 to a function with a controlling result of a limited type. This is a
11376 current implementation restriction.
11377 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
11378 (Check_Dispatching_Operation): Do no emit a warning if the controlling
11379 argument is an interface type that is a generic formal.
11380 (Is_Interface_Subprogram): Removed.
11381 (Check_Dispatching_Operation): If the subprogram is not a dispatching
11382 operation, check the formals to handle the case in which it is

12196 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
12197 abstract interface type, the static analysis is not enough to know if
12198 the interface is implemented or not by the source tagged type. Hence
12199 we must pass the work to the expander to generate the required code to
12200 evaluate the conversion at run-time.
12201 (Resolve_Equality_Op): Do not apply previous
12202 transformation if expansion is disasbled, to prevent anomalies when

12838 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12839 Thomas Quinot <quinot@adacore.com>
12841 * checks.adb (Build_Discriminant_Checks): If the expression being
12842 checks is an aggregate retrieve the values of its discriminants to
12843 generate the check, rather than creating a temporary and a reference
12845 (Apply_Access_Check): Rewritten to handle new Is_Known_Null flag
12846 (Install_Null_Excluding_Check): Ditto
12847 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,
12848 not for the renamed object, so that the actual itype is attached in the

12857 switches for the compiler.
12858 (Scan_Make_Switches): Do not allow numeric debug switches for gnatmake
12859 (Scan_Make_Switches): When failing with an illegal switch, output an
12860 error message with the full switch.
12861 Eliminate numeric switches for binder/gnatmake
12863 * switch.ads, switch.adb (Bad_Switch): New procedure
12865 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
12866 Remove 0-9 as debug flag character possibilities
12867 -d is now controlling the primary stack size when its value is a
12868 positive. Also add checks against invalid values, and support for kb,
12869 mb. Ditto for -D switch.
12871 2006-02-13 Robert Dewar <dewar@adacore.com>
12872 Serguei Rybin <rybin@adacore.com>
12874 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
12875 save/restore routines.
12876 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
12877 were not always properly handled previously.
12878 Since we are changing the tree format anyway, also get rid of the
12879 junk obsolete Immediate_Errors flag.
12880 (Tree_Read): Change the way of reading Tree_Version_String - now we
12881 read the version string from the tree even if its length is not the
12882 same as the length of the version string computed from Gnatvsn.
12883 (Search_Directory_Present): New Boolean flag for the compiler.
12884 Define Tree_Version_String as a dynamic string.
12885 (Default_Stack_Size): new variable, used to handle switch -d.
12888 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
12889 only for main unit.
12890 Add pragma Ada_2005 (synonym for Ada_05)
12891 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
12892 were not always properly handled previously.
12894 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
12895 explicit Ada_95 to Ada_2005.
12897 2006-02-13 Javier Miranda <miranda@adacore.com>
12898 Robert Dewar <dewar@adacore.com>
12899 Ed Schonberg <schonberg@adacore.com>
12901 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
12902 against errors in the source program: a private types for which the
12903 corresponding full type declaration is missing and pragma CPP_Virtual
12905 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
12906 (Is_Known_Null): New flag
12907 (Has_Pragma_Pure): New flag
12908 (No_Return): Present in all entities, set only for procedures
12909 (Is_Limited_Type): A type whose ancestor is an interface is limited if
12910 explicitly declared limited.
12911 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
12912 entities. Only used for component marked Is_Tag. If present it stores
12913 the Offset_To_Top function used to provide this value in tagged types
12914 whose ancestor has discriminants.
12916 * exp_ch2.adb: Update status of new Is_Known_Null flag
12918 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
12920 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
12921 the categorization sense if Is_Pure was set by pragma Pure_Function.
12923 2006-02-13 Quentin Ochem <ochem@adacore.com>
12924 Olivier Hainque <hainque@adacore.com>
12926 * bindusg.adb: Updated documentation for -d and -D switches.
12928 * raise.h (__gnat_set_globals): added new parameter for
12929 Default_Stack_Size.
12931 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
12932 (__gnat_handle_vms_condition): Adjust context before raise.
12933 (__gnat_install_handler): Restore the global vector setup for GCC
12934 versions before 3.4, as the frame based circtuitry is not available
12936 (__gnat_set_globals): added a parameter default_stack_size
12937 (__gl_default_stack_size): new variable.
12939 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12941 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
12942 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
12943 does not exist in the Ada RM.
12944 (Compatible_Int_Bounds): Determine whether two integer range bounds
12945 are of equal length and have the same start and end values.
12946 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
12947 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
12948 aggregate when it is part of an object declaration.
12949 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
12950 constrains discriminants of its parent, add explicitly the discriminant
12951 constraints of the ancestor by retrieving them from the
12952 stored_constraint of the parent.
12954 2006-02-13 Robert Dewar <dewar@adacore.com>
12956 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
12957 attribute Mechanism_Code is applied to renamed subprogram, modify
12958 prefix to point to base subprogram.
12959 Max/Min attributes now violate Restriction No_Implicit_Conditionals
12961 * sinfo.ads: Document that Mechanism_Code cannot be applied to
12962 renamed subprograms so that the front-end must replace the prefix
12965 2006-02-13 Javier Miranda <miranda@adacore.com>
12966 Gary Dismukes <dismukes@adacore.com>
12968 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
12969 availability of RE_Interface_Tag.
12970 (Build_Initialization_Call): Fix wrong access to the discriminant value.
12971 (Freeze_Record_Type): Do not generate the tables associated with
12972 timed and conditional dispatching calls through synchronized
12973 interfaces if compiling under No_Dispatching_Calls restriction.
12974 When compiling for Ada 2005, for a nonabstract
12975 type with a null extension, call Make_Controlling_Function_Wrappers
12976 and insert the wrapper function declarations and bodies (the latter
12977 being appended as freeze actions).
12978 (Predefined_Primitive_Bodies): Do not generate the bodies of the
12979 predefined primitives associated with timed and conditional
12980 dispatching calls through synchronized interfaces if we are
12981 compiling under No_Dispatching_Calls.
12982 (Build_Init_Procedure): Use RTE_Available to check if a run-time
12983 service is available before generating a call.
12984 (Make_Controlling_Function_Wrappers): New procedure.
12985 (Expand_N_Full_Type_Declaration): Create a class-wide master for
12986 access-to-limited-interfaces because they can be used to reference
12987 tasks that implement such limited interface.
12988 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
12989 procedure spec and body of the Offset_To_Top function that is generated
12990 when the parent of a type with discriminants has secondary dispatch
12992 (Init_Secondary_Tags): Handle the case in which the parent of the type
12993 containing secondary dispatch tables has discriminants to generate the
12994 correct arguments to call Set_Offset_To_Top.
12995 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
12997 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
12998 Add Wide_[Wide_]Expanded_Name.
12999 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
13000 the same functionality of Get_Prim_Op_Address but applied to predefined
13001 primitive operations because the pointers to the predefined primitives
13002 are now saved in a separate table.
13003 (Parent_Size): Modified to get access to the separate table of primitive
13004 operations or the parent type.
13005 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
13006 functionality of Set_Prim_Op_Address but applied to predefined primitive
13008 (Set_Signature): New subprogram used to store the signature of a DT.
13009 (Displace): If the Offset_To_Top value is not static then call the
13010 function generated by the expander to get such value; otherwise use
13011 the value stored in the table of interfaces.
13012 (Offset_To_Top): The type of the actual has been changed to Address to
13013 give the correct support to tagged types with discriminants. In this
13014 case this value is stored just immediately after the tag field.
13015 (Set_Offset_To_Top): Two new formals have been added to indicate if the
13016 offset_to_top value is static and hence pass this value to the run-time
13017 to store it in the table of interfaces, or else if this value is dynamic
13018 and then pass to the run-time the address of a function that is
13019 generated by the expander to provide this value for each object of the
13022 * rtsfind.ads (Default_Prin_Op_Count): Removed.
13023 (Default_Prim_Op_Count): New entity
13024 (Get_Predefined_Prim_Op_Address): New entity
13025 (Set_Predefined_Prim_Op_Address): New entity
13026 (RE_Set_Signature): New entity
13028 2006-02-13 Thomas Quinot <quinot@adacore.com>
13029 Ed Schonberg <schonberg@adacore.com>
13031 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
13032 Make_Adjust_Call done for a newly-allocated object.
13034 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
13035 in a subprogram are wrapped in a cleanup block, indicate that the
13036 subprogram contains an inner block with an exception handler.
13037 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
13038 Adjust call is for a newly-allocated object. In that case we must not
13039 assume that the finalization list chain pointers are correct (since they
13040 come from a bit-for-bit copy of the original object's pointers) so if
13041 the attach level would otherwise be zero (no change), we set it to 4
13042 instead to cause the pointers to be reset to null.
13044 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
13045 reset chain pointers to null.
13047 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13049 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
13050 string, and the context requires a loop for the assignment (e.g.
13051 because the left-hand side is packed), generate a unique name for the
13052 temporary that holds the string, to prevent spurious name clashes.
13054 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13055 Javier Miranda <miranda@adacore.com>
13056 Robert Dewar <dewar@adacore.com>
13057 Gary Dismukes <dismukes@adacore.com>
13059 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
13060 return unconstrained arrays.
13062 (Expand_Call): An indirect call through an access parameter of a
13063 protected operation is not a protected call.
13064 Add circuit to raise CE in Ada 2005 mode following call
13065 to Raise_Exception.
13066 (Register_DT_Entry): Do nothing if
13067 the run-time does not give support to abstract interfaces.
13068 (Freeze_Subprogram): In case of dispatching operations, do not generate
13069 code to register the operation in the dispatch table if the source
13070 is compiled with No_Dispatching_Calls.
13071 (Register_Predefined_DT_Entry): Generate code that calls the new
13072 run-time subprogram Set_Predefined_Prim_Op_Address instead of
13073 Set_Prim_Op_Address.
13075 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
13076 on array assignments if the right-hand side is a function call that has
13077 been inlined. Check is performed on the assignment in the block.
13078 (Process_Bounds): If bounds and range are overloaded, apply preference
13079 rule for root operations to disambiguate, and diagnose true ambiguity.
13080 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
13081 a tag-indeterminate right-hand side even when Expander_Active is True.
13082 Needed to ensure that dispatching calls to T'Input are allowed and
13083 get the tag of the target class-wide object.
13085 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
13086 an inherited primitive operation that already overrides several
13087 abstract interface primitives. For transitivity, the new entity must
13088 also override all the abstract interface primitives covered by the
13089 inherited overriden primitive.
13090 Emit warning if new entity differs from homograph in same scope only in
13091 that one has an access parameter and the other one has a parameter of
13092 a general access type with the same designated type, at the same
13093 position in the signature.
13094 (Make_Inequality_Operator): Use source locations of parameters and
13095 subtype marks from corresponding equality operator when creating the
13096 tree structure for the implicit declaration of "/=". This does not
13097 change anything in behaviour except that the decoration of the
13098 components of the subtree created for "/=" allows ASIS to get the
13099 string images of the corresponding identifiers.
13100 (Analyze_Return_Statement): Remove '!' in warning message.
13101 (Check_Statement_Sequence): Likewise.
13102 (Analyze_Subprogram_Body): For an access parameter whose designated type
13103 is an incomplete type imported through a limited_with clause, use the
13104 type of the corresponding formal in the body.
13105 (Check_Returns): Implicit return in No_Return procedure now raises
13106 Program_Error with a compile time warning, instead of beging illegal.
13107 (Has_Single_Return): Function returning unconstrained type cannot be
13108 inlined if expression in unique return statement is not an identifier.
13109 (Build_Body_To_Inline): It is possible to inline a function call that
13110 returns an unconstrained type if all return statements in the function
13111 return the same local variable. Subsidiary procedure Has_Single_Return
13112 verifies that the body conforms to this restriction.
13114 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
13115 same type, and one of them is of an anonymous access type, convert
13116 the other operand to it, so that this is a valid binary operation for
13118 (Resolve_Type_Conversion): Handle subtypes of protected types and
13119 task types when accessing to the corresponding record type.
13120 (Resolve_Allocator): Add '\' in 2-line warning message.
13121 Remove '!' in warning message.
13122 (Resolve_Call): Add '\' in 2-line warning message.
13123 (Valid_Conversion): Likewise.
13124 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
13125 resulting type may be an access type with an implicit dereference.
13126 Obtain the proper component from the designated type.
13127 (Make_Call_Into_Operator): Handle properly a call to predefined equality
13128 given by an expanded name with prefix Standard, when the operands are
13129 of an anonymous access type.
13130 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
13131 Explicit_Dereference and Resolve_Selected_Component, to verify that the
13132 prefix of the expression is not of an incomplete type. Allows full
13133 diagnoses of all semantic errors.
13134 (Resolve_Actuals): If the actual is an allocator whose directly
13135 designated type is a class-wide interface we build an anonymous
13136 access type to use it as the type of the allocator. Later, when
13137 the subprogram call is expanded, if the interface has a secondary
13138 dispatch table the expander will add a type conversion to force
13139 the displacement of the pointer.
13140 (Resolve_Call): If a function that returns an unconstrained type is
13141 marked Inlined_Always and inlined, the call will be inlined and does
13142 not require the creation of a transient scope.
13143 (Check_Direct_Boolean_Op): Removed
13144 (Resolve_Comparison_Op): Remove call to above
13145 (Resolve_Equality_Op): Remove call to above
13146 (Resolve_Logical_Op): Inline above, since this is only call.
13147 (Valid_Conversion): Handle properly conversions between arrays of
13148 convertible anonymous access types.
13151 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
13152 the literal in an unchecked conversion, because GCC 4.x needs a static
13153 value for a string bound.
13155 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13156 Hristian Kirtchev <kirtchev@adacore.com>
13158 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
13159 components of the corresponding record, take into account component
13160 definitions that are access definitions.
13161 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
13162 procedure is not considered a dispatching call and will be expanded
13165 2006-02-13 Javier Miranda <miranda@adacore.com>
13167 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
13168 controlling argument of the dispatching call is an abstract interface
13169 class-wide type then we use it directly.
13170 Check No_Dispatching_Calls restriction.
13171 (Default_Prim_Op_Position): Remove the code that looks for the last
13172 entity in the list of aliased subprograms. This code was wrong in
13174 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
13175 when the source is compiled with the No_Dispatching_Calls restriction.
13176 (Init_Predefined_Interface_Primitives): No need to inherit primitives
13177 if we are compiling with restriction No_Dispatching_Calls.
13178 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
13179 subprograms if we are compiling under No_Dispatching_Calls restriction.
13180 (Make_DT): Generate a dispatch table with a single dummy entry if
13181 we are compiling with the No_Dispatching_Calls restriction. In
13182 addition, in this case we don't generate code that calls to the
13183 following run-time subprograms: Set_Type_Kind, Inherit_DT.
13184 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
13185 of this subprogram if compiling with the No_Dispatching_Calls
13187 (Expand_Type_Conversion): Instead of using the actual parameter,
13188 the argument passed as parameter to the conversion function was
13189 erroneously referenced by the expander.
13190 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
13191 Set_Predefined_Primitive_Op_Address and Set_Signature.
13192 (Expand_Dispatching_Call): Generate call to
13193 Get_Predefined_Prim_Op_Address for predefined primitives.
13194 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
13195 predefined primitives.
13196 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
13197 primitives we reserve one dummy entry to ensure that the tag does not
13198 point to some memory that is associated with some other object. In
13199 addition, remove all the old code that generated the assignments
13200 associated with the signature of the dispatch table and replace them
13201 by a call to the new subprogram Set_Signature.
13202 (Set_All_DT_Position): Change the algorithm because now we have a
13203 separate dispatch table associated with predefined primitive operations.
13204 (Expand_Interface_Conversion): In case of non-static offset_to_top
13205 add explicit dereference to get access to the object after the call
13206 to displace the pointer to the object.
13207 (Expand_Interface_Thunk): Modify the generation of the actual used
13208 in the calls to the run-time function Offset_To_Top to fulfil its
13210 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
13212 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13214 * exp_dist.adb (Copy_Specification): For access parameters, copy
13215 Null_Exclusion flag, which will have been set for stream subprograms
13218 2006-02-13 Pascal Obry <obry@adacore.com>
13220 * expect.c (__gnat_expect_portable_execvp): New implementation. The
13221 previous implementation was using the C runtime spawnve routine but
13222 the corresponding wait was using directly the Win32 API. This was
13223 causing some times a lock when waiting for an event using
13224 WaitForSingleObject in __gnat_waitpid. This new implementation uses
13225 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
13226 API fixes this problem.
13228 2006-02-13 Robert Dewar <dewar@adacore.com>
13230 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
13233 2006-02-13 Thomas Quinot <quinot@adacore.com>
13235 * exp_pakd.ads: Fix typos in comments.
13237 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
13238 array reference that is an explicit dereference, mark the converted
13239 (packed) array reference as analyzed to prevent a forthcoming
13240 reanalysis from resetting its type to the original (non-packed) array
13243 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13244 Javier Miranda <miranda@adacore.com>
13245 Eric Botcazou <ebotcazou@adacore.com>
13247 * exp_util.ads, exp_util.adb (Find_Prim_Op,
13248 Is_Predefined_Primitive_Operation): When
13249 searching for the predefined equality operator, verify that operands
13250 have the same type.
13251 (Is_Predefined_Dispatching_Operation): Remove the code that looks
13252 for the last entity in the list of aliased subprograms. This code
13253 was wrong in case of renamings.
13254 (Set_Renamed_Subprogram): New procedure
13255 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
13256 Exp_Type constant computed when entering this subprogram.
13257 (Known_Null): New function
13258 (OK_To_Do_Constant_Replacement): New function
13259 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
13260 (Side_Effect_Free): An attribute reference 'Input is not free of
13261 side effect, unlike other attributes that are functions. (from code
13263 (Remove_Side_Effects): Expressions that involve packed arrays or records
13264 are copied at the point of reference, and therefore must be marked as
13265 renamings of objects.
13266 (Is_Predefined_Dispatching_Operation): Return false if the operation is
13267 not a dispatching operation.
13270 (Remove_Side_Effects): Lift enclosing type conversion nodes for
13271 elementary types in all cases.
13273 2006-02-13 Javier Miranda <miranda@adacore.com>
13275 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
13276 task types when accessing to the corresponding record type.
13277 Remove '!' in warning message.
13279 2006-02-13 Olivier Hainque <hainque@adacore.com>
13281 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
13282 to avoid useless and space inefficient overalignments on targets where
13283 Max_Alignment is larger than 16.
13285 2006-02-13 Pascal Obry <obry@adacore.com>
13287 * g-catiio.adb (Sec_Number): New type used to compute the number of
13288 seconds since 1-1-1970.
13289 (Image) [Natural]: The parameter was an Integer, as we can't deal with
13290 negative numbers (years, months...) it is better to have a Natural here.
13292 (Image) [Number]: Change parameter from Long_Integer to Number.
13293 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
13294 overflow for dates past year 2038.
13296 2006-02-13 Matthew Heaney <heaney@adacore.com>
13298 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
13301 2006-02-13 Arnaud Charlet <charlet@adacore.com>
13303 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
13305 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that

13310 * gnatcmd.adb (Rules_Switches): New table
13311 (Add_To_Rules_Switches): New procedure
13312 (GNATCmd): For command CHECK, put all options following "-rules" in the
13313 Rules_Switches table. Append these -rules switches after the -cargs
13316 2006-02-13 Robert Dewar <dewar@adacore.com>
13318 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
13319 These two cases were generating incorrect output, and if this unit
13320 was built with checks on, generated a discriminant mismatch constraint
13323 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13324 Robert Dewar <dewar@adacore.com>
13326 * lib-xref.adb (Get_Type_Reference): For a private type whose full
13327 view is an array type, indicate the component type as well, for
13328 navigation purposes.
13329 (Generate_Reference): Don't consider array ref on LHS to be a case
13330 of violating pragma Unreferenced.
13331 Do not give Ada 2005 warning except on real reference.
13333 2006-02-13 Vincent Celier <celier@adacore.com>
13335 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
13336 main source, add switch -mdebug-main=_ada_ so that the executable can
13337 be debugged by the standard VMS debugger.
13338 (Gnatmake): Set No_Main_Subprogram to True when there is no main
13339 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
13340 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
13341 of the last source, as the binding and linking phases are never
13343 Set all executable obsolete when rebuilding a library.
13345 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
13348 2006-02-13 Javier Miranda <miranda@adacore.com>
13351 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
13352 code to improve the error message reported when the program has
13353 declarations of abstract interface types and it is not compiled with
13354 the -gnat05 switch.
13355 (P_Access_Definition): Reorganize the code to improve the error
13356 message reported when the new Ada 2005 syntax for anonymous
13357 access types is used and the program is not compiled with the

13380 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
13381 unknown, use the location of the project to report the error.
13382 (When_No_Sources): New global variable
13383 (Report_No_Ada_Sources): New procedure
13384 (Check): New parameter When_No_Sources. Set value of global variable
13386 (Find_Sources): Call Report_No_Ada_Sources when appropriate
13387 (Get_Sources_From_File): Ditto
13388 (Warn_If_Not_Sources): Better warning messages indicating the unit name
13391 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
13392 Call Prj.Proc.Process with parameter When_No_Sources.
13394 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
13395 Call Recursive_Check with parameter When_No_Sources.
13396 (Recursive_Check): New parameter When_No_Sources. Call itself and
13397 Prj.Nmsc.Check with parameter When_No_Sources.
13398 (Process): New parameter When_No_Sources. Call Check with parameter
13400 (Copy_Package_Declarations): New procedure to copy renamed parameters
13401 and setting the location of the declared attributes to the location
13402 of the renamed package.

13408 * prj-makr.adb (Make): Preserve the comments from the original project
13410 When removing nodes (attributes Source_Dirs, Source_Files,
13411 Source_List_File and package Naming), save the comments and attach the
13412 saved comments to the newly created nodes.
13413 Do not add a with clause for the naming package if one already exists.
13415 2006-02-13 Javier Miranda <miranda@adacore.com>

13421 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
13422 aliased entities to look for the overriden abstract interface
13424 (Is_Interface_Subprogram): Complete documentation.
13425 (Check_Dispatching_Operation): Do not generate code to register the
13426 operation in the dispatch table if the source is compiled with
13427 restriction No_Dispatching_Calls.
13428 (Override_Dispatching_Operation): Check for illegal attempt to override
13429 No_Return procedure with procedure that is not No_Return
13430 (Check_Dispatching_Call): Suppress the check for an abstract operation
13431 when the original node of an actual is a tag-indeterminate attribute
13432 call, since the attribute, which must be 'Input, can never be abstract.
13433 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
13434 call to the Input attribute (even when rewritten).
13435 (Propagate_Tag): Augment comment to indicate the possibility of a call
13436 to an Input attribute.
13438 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
13439 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
13441 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
13442 No_Wide_Characters is no longer partition-wide
13443 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
13446 2006-02-13 Douglas Rupp <rupp@adacore.com>
13448 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
13450 2006-02-13 Javier Miranda <miranda@adacore.com>
13452 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
13453 handles default-initialized components to keep separate the management
13454 of this feature but also avoid the unrequired resolution and
13455 expansion of components that do not have partially initialized
13457 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
13458 (Check_Bounds): Likewise.
13459 (Check_Length): Likewise.
13461 2006-02-13 Javier Miranda <miranda@adacore.com>
13462 Ed Schonberg <schonberg@adacore.com>
13464 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
13465 abstract interface type call analyze_and_resolve to expand the type
13466 conversion into the corresponding displacement of the
13467 reference to the base of the object.
13468 (Eval_Attribute, case Width): For systems where IEEE extended precision
13469 is supported, the maximum exponent occupies 4 decimal digits.
13470 (Accessibility_Message): Add '\' in 2-line warning message.
13471 (Resolve_Attribute): Likewise.
13472 (case Attribute_Access): Significantly revise checks
13473 for illegal access-to-subprogram Access attributes to properly enforce
13474 the rules of 3.10.2(32/2).
13475 Diagnose use of current instance with an illegal attribute.
13477 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
13479 (Enclosing_Generic_Unit): New function to return a node's innermost
13480 enclosing generic declaration node.
13481 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
13482 (Type_Access_Level): The accessibility level of anonymous acccess types
13483 associated with discriminants is that of the current instance of the
13484 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
13485 (Compile_Time_Constraint_Error): Handle case of conditional expression.
13486 (Kill_Current_Values_For_Entity): New function
13487 (Enter_Name): Change formal type to Entity_Id
13489 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
13490 Ed Schonberg <schonberg@adacore.com>
13491 Gary Dismukes <dismukes@adacore.com>
13493 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
13494 Analyze_Compilation_Unit.
13495 Detect and warn on redundant with clauses detected in a package spec
13496 and/or body when -gnatwr is used.
13497 (Analyze_Context): Analyze config pragmas before other items
13498 (Install_Context_Items): Don't analyze config pragmas here
13499 (Install_Limited_Withed_Unit): Set limited entity of package in
13500 with_clause so that cross-reference information or warning messages on
13501 unused packages can be properly generated
13502 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
13503 has Error_Posted set. Prevent infinite loops in illegal programs.
13504 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
13505 to the point of the error test requiring the current unit to be private.
13506 This ensures that private with clauses are not exempted from the basic
13507 checking for being a descendant of the same library unit parent as a
13508 withed private descendant unit.
13509 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
13510 handle private with clauses properly, as well as to account for cases
13511 where the withed unit is a public descendant of a private ancestor
13512 (in which case the current unit must be a descendant of the private
13513 ancestor's parent). The spec comments were updated accordingly. Also,
13514 the old error message in this subprogram was replaced with error
13515 messages that mirror the errors tested and reported by
13516 Check_Private_Child_Unit.
13517 Parameter and variable names improved for readability.
13518 (Install_Limited_Context_Clauses): Remove test for a withed unit being
13519 private as the precondition for calling
13520 Check_Private_Limited_Withed_Unit since that subprogram has been
13521 revised to test public units as well as private units.

13526 Javier Miranda <miranda@adacore.com>
13528 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
13529 that Scope_Stack.First = 1.
13530 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13531 were not always properly handled previously.
13532 (Formal_Entity): Complete rewrite, to handle properly some complex case
13533 with multiple levels of parametrization by formal packages.
13534 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
13535 to the corresponding derived type declaration for proper semantics.
13537 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
13538 (Check_Component): Enforce restriction on components of
13539 unchecked_unions: a component in a variant cannot contain tasks or
13541 (Unchecked_Union): Allow nested variants and multiple discriminants, to
13543 Add pragma Ada_2005 (synonym for Ada_05)
13544 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13545 were not always properly handled previously.
13546 Document that pragma Propagate_Exceptions has no effect
13547 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
13548 (Set_Convention_From_Pragma): Check that if a convention is
13549 specified for a dispatching operation, then it must be
13550 consistent with the existing convention for the operation.
13551 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
13552 longer required to specify an vtable-ptr component in the record. For
13553 compatibility reasons we leave the support for the previous definition.
13554 (Analyze_Pragma, case No_Return): Allow multiple arguments
13556 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
13557 non-overrideen inherited operation with a controlling result as
13558 illegal only its implicit declaration comes from the derived type
13559 declaration of its result's type.
13560 (Check_Possible_Deferred_Completion): Relocate the object definition
13561 node of the subtype indication of a deferred constant completion rather
13562 than directly analyzing it. The analysis of the generated subtype will
13563 correctly decorate the GNAT tree.
13564 (Record_Type_Declaration): Check whether this is a declaration for a
13565 limited derived record before analyzing components.
13566 (Analyze_Component_Declaration): Diagnose record types not explicitly
13567 declared limited when a component has a limited type.
13568 (Build_Derived_Record_Type): Code reorganization to check if some of
13569 the inherited subprograms of a tagged type cover interface primitives.
13570 This check was missing in case of a full-type associated with a private
13572 (Constant_Redeclaration): Check that the subtypes of the partial and the
13573 full view of a constrained deferred constant statically match.
13574 (Mentions_T): A reference to the current type in an anonymous access
13575 component declaration must be an entity name.
13576 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
13577 class_wide type to refer to full type, not to the incomplete one.
13578 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
13579 available. Required to give support to the certified run-time.
13580 (Analyze_Component_Declaration): In case of anonymous access components
13581 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
13582 (Process_Discriminants): For an access discriminant, use the
13583 discriminant specification as the associated_node_for_itype, to
13584 simplify accessibility checks.
13586 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13587 Javier Miranda <miranda@adacore.com>
13589 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
13590 abstract interpretations on an operator, remove interpretations that
13591 yield Address or a type derived from it, if one of the operands is an
13593 (Try_Object_Operation.Try_Primitive_Operation,
13594 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
13595 location when creating the new reference to a primitive or class-wide
13596 operation as a part of rewriting a subprogram call.
13597 (Try_Primitive_Operations): If context requires a function, collect all
13598 interpretations after the first match, because there may be primitive
13599 operations of the same type with the same profile and different return
13600 types. From code reading.
13601 (Try_Primitive_Operation): Use the node kind to choose the proper
13602 operation when a function and a procedure have the same parameter
13604 (Complete_Object_Operation): If formal is an access parameter and prefix
13605 is an object, rewrite as an Access reference, to match signature of
13606 primitive operation.
13607 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
13608 by an expanded name with prefix Standard, when the operands are of an
13609 anonymous access type.
13610 (Remove_Abstract_Operations): If the operation is abstract because it is
13611 inherited by a user-defined type derived from Address, remove it as
13612 well from the set of candidate interpretations of an overloaded node.
13613 (Analyze_Membership_Op): Membership test not applicable to cpp-class
13616 2006-02-13 Bob Duff <duff@adacore.com>
13618 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
13619 redundant use clauses.
13620 In particular, if the scope of two use clauses overlaps, but one is not
13621 entirely included in the other, we should not warn. This can happen
13622 with nested packages.
13623 (Analyze_Subprogram_Renaming): Protect the compiler against previously
13624 reported errors. The bug was reported when the compiler was built
13625 with assertions enabled.
13626 (Find_Type): If the node is a 'Class reference and the prefix is a
13627 synchronized type without a corresponding record, return the type
13630 2006-02-13 Javier Miranda <miranda@adacore.com>
13632 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
13633 if this is the full-declaration associated with a private declaration
13634 that implement interfaces, then the private type declaration must be
13636 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
13637 as aliased. The use of the 'access attribute is not available for such
13638 object (for this purpose the object should be explicitly marked as
13639 aliased, but being an anonymous type this is not possible).
13641 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13642 Robert Dewar <dewar@adacore.com>
13644 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
13645 compilation unit is an elaboration scope.
13646 (Add_Task_Proc): Add '\' in 2-line warning message.
13647 (Activate_All_Desirable): Deal with case of unit with'ed by parent
13649 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13650 Javier Miranda <miranda@adacore.com>
13652 * sem_type.adb (Write_Overloads): Improve display of candidate
13654 (Add_One_Interp): Do not add to the list of interpretations aliased
13655 entities corresponding with an abstract interface type that is an
13656 immediate ancestor of a tagged type; otherwise we have a dummy
13657 conflict between this entity and the aliased entity.
13658 (Disambiguate): The predefined equality on universal_access is not
13659 usable if there is a user-defined equality with the proper signature,
13660 declared in the same declarative part as the designated type.
13661 (Find_Unique_Type): The universal_access equality operator defined under
13662 AI-230 does not cover pool specific access types.
13663 (Covers): If one of the types is a generic actual subtype, check whether
13664 it matches the partial view of the other type.
13666 2006-02-13 Thomas Quinot <quinot@adacore.com>
13668 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
13669 line. This is necessary to allow In_Extended_Main_Unit to provide
13670 correct results for itypes while writing out expanded source.
13671 (Close_File): No need to update the source_index_table here since it's
13672 now done for each line.
13674 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13675 Robert Dewar <dewar@adacore.com>
13677 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
13678 preserve the source unit where the itype is declared, and prevent a
13680 (Note_Implicit_Run_Time_Call): New procedure
13681 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
13684 * sprint.ads: Document use of $ for implicit run time routine call

13688 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
13691 2006-02-13 Bob Duff <duff@adacore.com>
13693 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
13694 Scan_Unsigned, so we do not scan leading blanks and sign twice.
13695 Integer'Value("- 5") and Integer'Value("-+5") now correctly
13696 raise Constraint_Error.
13698 * s-vallli.adb (Scan_Long_Long_Integer): Call
13699 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
13700 do not scan leading blanks and sign twice.
13701 Integer'Value("- 5") and Integer'Value("-+5") now correctly
13702 raise Constraint_Error.
13704 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
13705 Scan_Long_Long_Unsigned): Split out most of the processing from
13706 Scan_Long_Long_Unsigned out into
13707 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
13708 This prevents scanning leading blanks and sign twice.
13709 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
13712 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
13713 out most of the processing from Scan_Unsigned out into
13714 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
13715 This prevents scanning leading blanks and sign twice.
13717 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
13718 use with Modular'Value attribute.
13719 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

13917 * a-taster.ads, a-taster.adb: New files.
13919 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
13920 link to the version that does nothing. This way the task termination
13921 routine is not executed twice for the environment task when finishing
13922 because of an unhandled exception.
13924 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
13925 handler because of an unhandled exception.
13927 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

13933 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
13934 non-tasking version of the soft link for task termination. We do
13935 nothing since if we are using the non-tasking version it
13936 means that the task termination functionality is not used.
13937 (Null_Finalize_Global_List): Add this null version for the procedure
13938 in charge of finalizing the global list for controlled objects.
13939 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
13940 instead for handling run-time termination in a more flexible way.
13941 (Adafinal_NT): This new procedure will take care of finalizing the
13942 global list for controlled objects if needed, but no tasking
13945 * s-tarest.adb (Task_Lock): Do not try to lock again the
13946 Global_Task_Lock if we already own it. Otherwise, we get blocked in
13947 some run-time operations.
13948 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
13949 until all nested locks have been released.
13950 (Task_Wrapper): Call the fall-back task termination handler. It
13951 applies to all tasks but the environment task.
13952 (Finalize_Global_Tasks): Add the call for the task termination
13953 procedure for the environment task.
13954 (Task_Wrapper): suppress warnings around declaration of
13955 Secondary_Stack_Address.

13958 moved to the Common_ATCB record.
13959 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
13960 Common_ATCB record.
13961 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
13962 Common_ATCB record.
13964 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
13965 Fall_Back_Handler, and Specific_Handler.

13968 defined in Ada.Task_Termination, to avoid circular dependencies.
13969 (Termination_Handler): Redefine this type here, alredy defined in
13970 Ada.Task_Termination, for avoiding circular dependencies.
13971 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
13972 for storing task termination handlers. In addition,
13973 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
13974 Common_ATCB because it is used by both the regular and the restricted
13976 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
13977 Common_ATCB because it is used by both the regular and the restricted
13979 (Common_ATCB): Added a dynamic task analyzer field.
13981 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
13982 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

13984 tasks but the environment task.
13985 (Finalize_Global_Tasks): Call the task termination procedure for the
13986 environment task. The call to Finalize_Global_List is now performed
13987 using the soft links mechanism.
13988 (Task_Wrapper): added dynamic stack analysis.
13990 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
13991 potentially blocking operations has been moved from
13992 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
13993 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
13994 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
13995 this run-time check.
13997 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
13998 of task termination procedure.
13999 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

14041 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
14042 to the specification because the frontend generates code that uses this
14044 (Set_Interface_Table): Add missing assertion.
14045 Update documentation describing the run-time structure.
14046 (Displace): New subprogram that displaces the pointer to the object
14047 to reference one of its secondary dispatch tables.
14048 (IW_Membership): Modified to use the new table of interfaces.
14049 (Inherit_TSD): Modified to use the new table of interfaces.
14050 (Register_Interface_Tag): Use the additional formal to fill the
14051 contents of the new table of interfaces.
14052 (Set_Interface_Table): New subprogram that stores in the TSD the

14067 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
14068 in all the calls to Expand_Interface_Thunk. Instead of referencing the
14069 record component containing the tag of the secondary dispatch table we
14070 have to use the Offset_To_Top run-time function to get this information;
14071 otherwise if the pointer to the base of the object has been displace
14072 we get a wrong value if we use the 'position attribute.
14074 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
14075 all the calls to Expand_Interface_Thunk.
14076 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
14077 interfaces; hence the call to Set_Interface_Table was clearly wrong.

14079 ensure that the interfaces implemented by the ancestors are placed
14080 at the header of the generated list.
14081 (Expand_Interface_Conversion): Handle the case in which the displacement
14082 associated with the interface conversion is not statically known. In
14083 this case we generate a call to the new run-time subprogram Displace.

14085 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
14086 Get_Tagged_Kind and Set_Tagged_Kind.
14087 (Tagged_Kind): New function that determines the tagged kind of a type
14088 with respect to limitedness and concurrency and returns a reference to

14091 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
14092 primary dispatch table for a type.

14094 secondary dispatch table respectively of a tagged type.
14096 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.

14108 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
14109 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
14110 RE_TK_Tagged, RE_TK_Task.
14112 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
14113 Init_Secondary_Tags_Internal to allow its use with interface types and
14114 also to generate the code for the new additional actual required
14115 by Set_Offset_To_Top.
14116 (Build_Init_Statements): In case of components associated with abstract
14117 interface types there is no need to generate a call to its IP.
14118 (Freeze_Record_Type): Generate Select Specific Data tables only for
14120 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
14121 the bodies and specifications of the predefined primitive operations
14122 dealing with dispatching selects and abort, 'Callable, 'Terminated only
14123 for concurrent types.
14125 * exp_sel.ads, exp_sel.adb: New files.
14127 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
14128 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
14129 properly protected objects and attach handler in the case of the
14130 restricted profile.
14131 Move embeded package Select_Expansion_Utilities into a separate external
14133 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
14134 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
14135 (Build_K, Build_S_Assignment): New subprograms, part of the select
14136 expansion utilities.

14139 where the trigger is a dispatching procedure of a limited tagged type.
14141 2005-12-09 Olivier Hainque <hainque@adacore.com>
14143 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
14144 pointer initialization values. Make a SAVE_EXPR instead. Add comments
14145 about the use and expansion of SAVE_EXPRs in the various possible
14146 renaming handling cases.
14147 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
14148 abusing DECL_FCONTEXT.

14241 the iterator is quitting iteration on parent directory.
14243 2005-12-09 Javier Miranda <miranda@adacore.com>
14245 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
14246 and the assignment to a class-wide object, before the assignment we
14247 generate a run-time check to ensure that the tag of the Target is
14248 covered by the tag of the source.
14250 2005-12-09 Robert Dewar <dewar@adacore.com>
14252 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

14267 component associated with the secondary table of an abstract interface
14268 type, return the entity associated with such abstract interface type.
14269 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
14270 base type to create anonymous subtype, because entity may be a locally
14271 declared subtype or generic actual.
14272 (Find_Interface): New subprogram that given a tagged type and one of its
14273 component associated with the secondary table of an abstract interface
14274 type, return the entity associated with such abstract interface type.
14276 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
14277 conversion cannot be handled at compile time. In this case we pass this
14278 information to the expander to generate the appropriate code.

14313 copied component does not have a known static Esize, then reset
14314 the size and positional fields of the new component.
14315 (Analyze_Component_Declaration): A limited component is
14316 legal within a protected type that implements an interface.
14317 (Collect_Interfaces): Do not add to the list the interfaces that
14318 are implemented by the ancestors.
14319 (Derived_Type_Declaration): If the parent of the full-view is an
14320 interface perform a transformation of the tree to ensure that it has
14321 the same parent than the partial-view. This simplifies the job of the
14322 expander in order to generate the correct object layout, and it is
14323 needed because the list of interfaces of the full-view can be given in
14325 (Process_Full_View): The parent of the full-view does not need to be
14326 a descendant of the parent of the partial view if both parents are
14328 (Analyze_Private_Extension_Declaration): If declaration has an explicit
14329 "limited" the parent must be a limited type.

14343 (Process_Full_View): Improve the check for the "no hidden interface"
14344 rule as defined by AI-396.
14346 2005-12-09 Robert Dewar <dewar@adacore.com>
14348 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
14349 types, not on record subtypes.
14350 (Freeze_Entity): Code cleanup. Add barrier to the loop
14351 that generates the references for primitive operations. This allows to
14352 remove an unnecessary exception handler.

14403 available user-specified stream attributes on limited parameters to
14404 also test the type directly rather than only its underlying type (for
14405 Ada 95) and, in the case of Ada 2005, to check that the user-specified
14406 attributes are visible at the point of the subprogram declaration.
14407 For Ada 2005, the error message is modified to indicate that the
14408 type's stream attributes must be visible (again, only for -gnat05).

14440 types use the corresponding record type. This was not needed before
14441 the implementation of Ada 2005 synchronized types because
14442 concurrent types were never tagged types in Ada 95.

14570 * socket.c: Add extern int h_errno for rtems since networking header
14571 files are not available at this point in a tool bootstrap. Newlib

14575 Roger Sayle <roger@eyesopen.com>
14578 * misc.c (internal_error_function): Don't use vsprintf to format
14579 the error message text, instead use pp_format_text and the new

14590 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
14591 a temporary if taking the address of something that is neither
14592 reference, declaration, or constant, since the gimplifier
14593 can't handle that case.
14595 2005-11-17 Laurent GUERBY <laurent@guerby.net>
14598 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

14665 * gen-soccon.c: Complete value expansion should not be performed on
14666 TARGET, as it has the form of a math expression, and some components
14667 may be platform-defined macros.
14668 For VxWorks, generate the OK and ERROR values.
14669 New constants giving the sizes of the components of C struct timeval.

14675 * types.ads: Include All_Checks in Suppress_Array
14677 * checks.adb (Check_Needed): Remove kludge for a/=b rewritten as
14678 not(a=b), since we no longer do this rewriting, and hence it is not
14680 (Elaboration_Checks_Suppressed): Add special casing to
14681 deal with different cases of static and dynamic elaboration checks (all
14682 checks does not count in the first case, but does in the second).
14683 (Expr_Known_Valid): Do not assume that the result of any arbitrary
14684 function call is valid, since this is not the case.
14685 (Ensure_Valid): Do not apply validity check to a real literal
14686 in a universal or fixed context
14688 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
14689 elementary types using the operator in standard. It is cleaner not to
14690 modify the programmers intent, especially in the case of floating-point.
14691 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
14692 it did not matter because we always rewrote a/=b to not(a=b).
14693 (Expand_Allocator_Expression): For an allocator expression whose nominal
14694 subtype is an unconstrained packed type, convert the expression to its
14695 actual constrained subtype.
14696 Implement warning for <= or >= where < or > not possible
14697 Fix to Vax_Float tests (too early in many routines, causing premature
14698 Vax_Float expansions.
14700 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
14701 to be used with packages and generic packages as well as with
14703 (Suppress): Set All_Checks, but not Elaboration_Check, for case
14704 of pragma Suppress (All_Checks)
14705 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
14706 a string literal for precise control over warnings.
14707 Avoid raise of pragma in case of unrecognized pragma and just return
14710 * sem_prag.ads: Minor reformatting
14712 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
14713 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter
14714 Switch. Do not handle any exception.
14715 Include -gnatwx as part of -gnatg (warn on redundant parens)
14716 Allow optional = after -gnatm
14717 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
14718 longer sets Elaboration_Checks.
14719 Code to set warning mode moved to Sem_Warn
14720 so that it can be shared by pragma processing.
14722 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
14725 * s-taprop-solaris.adb:
14726 Change some <= to =, to avoid new warning

14734 * exp_vfpt.adb: Handle /= case
14735 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

14743 Increase default priority on Lynx from 15 to 17, and meet the Ada
14744 requirement that Default_Priority be ((Priority'First +
14745 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

14847 we are not defining the type.
14848 <E_Record_Type>: Likewise.
14849 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
14850 to get advantage of the new maybe_stabilize_reference interface, to
14851 ensure that what we reference is indeed stabilized instead of relying
14852 on assumptions on what the stabilizer does.
14853 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
14854 type imported through a limited_with clause, use its non-limited view.
14855 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
14857 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
14858 of #if sections + explicit comparisons of convention identifiers.

14860 before early-returning for certain types when code generation is
14862 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
14863 nullification of gnu_expr we do for objects with address clause and
14864 that we are not defining.
14865 (elaborate_expression_1): Do not create constants when creating
14866 variables needed by the debug info: the dwarf2 writer considers that
14867 CONST_DECLs is used only to represent enumeration constants, and emits
14869 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
14870 object with an address clause into an indirect reference, drop the
14871 initializing expression.
14873 (STACK_CHECK_BUILTIN): Delete.
14874 (STACK_CHECK_PROBE_INTERVAL): Likewise.

14883 subtype to build an actual type with bounds template.
14884 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
14885 is provided by the front-end, use that subtype to compute the size of
14886 the deallocated object.

14888 check for a potential violation of a No_Elaboration_Code restriction.

14893 maybe_stabilize, for common uses without restriction on lvalues and
14894 without need to check for the success indication.
14895 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
14896 pass false instead of 0 as the FORCE argument which is a bool.
14897 (Identifier_to_gnu): Remove checks ensuring that an renamed object
14898 attached to a renaming pointer has been properly stabilized, as no such
14899 object is attached otherwise.
14900 (call_to_gnu): Invoke create_var_decl to create the temporary when the
14901 function uses the "target pointer" return mechanism.
14902 Reinstate conversion of the actual to the type of the formal
14903 parameter before any other specific treatment based on the passing
14904 mechanism. This turns out to be necessary in order for PLACEHOLDER
14905 substitution to work properly when the latter type is unconstrained.

14909 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
14910 with extra arguments to control whether to recurse through non-values
14911 and to let the caller know if the stabilization has succeeded.
14913 * utils2.c (gnat_build_constructor): Only sort the fields for possible
14914 static output of record constructor if all the components are constant.
14915 (gnat_build_constructor): For a record type, sort the list of field
14916 initializers in increasing bit position order.
14917 Factor common code to build a storage type for an unconstrained object
14918 from a fat or thin pointer type and a constrained object type.
14919 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
14920 types variants, and process special cases of VIEW_CONVERT expressions
14921 as their NOP_EXPR counterpart to ensure we get to the
14922 CORRESPONDING_VARs associated with CONST_DECls.
14923 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
14924 on the right-hand side.
14926 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring

14929 are converting back to its original type.
14930 (convert) <JM input>: Fallthrough regular conversion code instead of
14931 extracting the object if converting to a type variant.
14932 (create_var_decl): When a variable has an initializer requiring code
14933 generation and we are at the top level, check for a potential violation
14934 of a No_Elaboration_Code restriction.
14935 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
14936 SIZE and SIZE_UNIT which we need for later back-annotations.

14939 is an unchecked union.

14941 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
14942 main variant, just replace the VIEW_CONVERT_EXPR.

15078 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
15079 for task component, in the case of a limited aggregate. The enclosed

15118 and related): For a prefix that is an explicit dereference of an
15119 access to unconstrained packed array type, annotate the dereference
15120 with an actual subtype so GIGI can make a correct size computation.
15121 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
15122 'Unrestricted_Access, if the designated type is an interface we
15123 add a type conversion to force the displacement of the pointer
15124 to the secondary dispatch table.
15125 Use Universal_Real instead of Long_Long_Float when we need a high
15126 precision float type for the generated code (prevents gratuitous
15127 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
15128 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
15129 'Terminated for task interface class-wide objects. Generate a call to
15130 the predefined dispatching routine used to retrieve the _task_id from
15131 a task corresponding record.

15156 if-statement that has elsif_parts, recompute the Current_Value node
15157 for any entity whose value is known from the condition of the first
15159 (Expand_N_Return_Statement): When returning a mutable record, convert
15160 the return value into its actual subtype in order to help the backend
15161 to return the actual size instead of the maximum. This is another
15162 aftermath of not returning mutable records on the sec-stack anymore.

15165 handling of error msg for suspicious reverse range iteration.

15181 a process handle, not need to convert.
15182 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.
15184 * g-expect.adb: (Kill): Document the new close parameter.
15185 (Close): Do not release the process handle in the kill there as

15189 2005-11-14 Robert Dewar <dewar@adacore.com>
15191 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

15193 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
15196 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we

15493 leave it more clear.
15494 (Analyze_Type_Declaration): If type has previous incomplete tagged

15551 whose default is abstract because the object type itself is abstract.
15552 (Find_Type): If the type is incomplete and appears as the prefix of a
15553 'Class reference, it is tagged, and its list of primitive operations
15554 must be initialized properly.

15584 statement to inhibit warning.
15585 (Resolve_Unary_Op): Do not produce a warning when
15586 processing an expression of the form -(A mod B)
15587 Use Universal_Real instead of Long_Long_Float when we need a high

16428 Move all target-specific file inclusions and macro definitions to
16429 gsocket.h, in order to ensure that any C code in socket.c will see a set
16430 of constants that is consistent with the contents of g-soccon.ads.
16431 This change also makes gen-soccon self-contained (removing dependencies
16432 upon GCC internal headers).
16434 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
16436 (To_Inet_Addr): Now a procedure instead of a function, more efficient.
16438 * socket.c: Minor reformatting.

16570 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
16571 from object notation, the original node is unanalyzed and carries no
16572 semantic information, so that accessiblity checks must be performed on
16573 the type of the actual itself.
16574 (Expand_N_Subprogram_Declaration): Change last actual parameter for
16575 compatibility with Build_Protected_Sub_Specification.
16576 (Check_Overriding_Inherited_Interfaces): Add suport to handle

16628 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
16629 position set is provided, we compute one in order to reduce the maximum
16630 length of the keys. This computation first selects a character
16631 position between 1 and the minimum length of the keys in order to
16632 avoid reducing one of the keys to an empty string.
16633 (Initialize, Compute): When the ratio V to K is too low, the algorithm
16634 does not converge. The initialization procedure now comes with a
16635 maximum number of iterations such that when exceeded, an exception is
16636 raised in Compute. The user can initialize this ratio to another value
16638 Reformating and updated headers.

16642 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
16643 that given an entity T creates and returns an Itype that duplicates the
16644 contents of T. The returned Itype has the null-exclusion
16645 attribute set to True, and its Etype attribute references T
16646 to keep the association between the two entities.

16745 New pragma Debug_Policy
16747 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
16749 Switch -gnata also sets Debug_Pragmas_Enabled
16751 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
16752 handle an explicit -gnata when compiling predefined files.
16754 2005-09-01 Vincent Celier <celier@adacore.com>
16756 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
16757 directories of projects that have no Ada sources.

16767 2005-09-01 Thomas Quinot <quinot@adacore.com>
16768 Ed Schonberg <schonberg@adacore.com>
16769 Robert Dewar <dewar@adacore.com>
16771 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
16772 'Address attribute reference with an overloaded prefix, use the
16773 location of the prefix (not the location of the attribute reference) as
16774 the error location.
16775 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
16776 a function renaming thereof, is a valid prefix for 'Size (where it is
16777 intepreted as a function call).
16778 (Statically_Denotes_Entity): New predicate to determine whether the
16779 prefix of an array attribute can be considered static.
16782 (Eval_Attr): Fix failure to evaluate Component_Size for

16793 Ed Schonberg <schonberg@adacore.com>
16795 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
16796 become local to the whole package.
16797 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
16798 the package was already analyzed the new algorithm "replaces" the
16799 real entities by the shadow ones. This is required to ensure that
16800 the order of these entities in the homonym chains does not change;
16801 otherwise we can have undefined references at linking time because
16802 in case of conflicts the external name of the entities will have
16803 a suffix that depends on the order of the entities in the chain.
16804 (Remove_Limited_With_Clause): Complementary code that completes the
16805 new algorithm and replaces the shadow entities by the real ones.
16806 (Install_Limited_Withed_Unit): When unchaining entities before the
16807 installation of the shadow entities, only regular entities of the
16808 public part must be taken into account. This is required to
16809 keep this routine in synch with the work done by Remove_Limited_
16811 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
16812 even if unit is analyzed, because the analysis of the unit is
16813 idempotent in any case, and the limited view of the unit may have to
16814 be installed for proper visibility.
16815 (Expand_Limited_With_Clause): Even if the unit in the implicit
16816 with_clause has been analyzed already, a limited view of the package
16817 must be built for the current context, if it does not exist yet.

16820 Javier Miranda <miranda@adacore.com>
16821 Gary Dismukes <dismukes@adacore.com>
16823 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
16824 defining entity for the instance body, make a new defining identifier
16825 rather than copying the entity of the spec, to prevent accidental
16826 sharing of the entity list.
16827 (Check_Private_View): When exchanging views of private types, build the
16828 list of exchanged views as a stack, to ensure that on exit the exchanges
16829 are undone in the proper order.
16830 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
16831 Restore the compilation environment in case of instantiation_error.
16832 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
16833 for an anonymous access result.
16834 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
16835 (Formal_Entity): Handle properly the case of a formal package that
16836 denotes a generic package renaming.
16838 2005-09-01 Thomas Quinot <quinot@adacore.com>
16840 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
16841 clause if the array aggregate is surrounded by parentheses.
16843 2005-09-01 Cyrille Comar <comar@adacore.com>
16844 Gary Dismukes <dismukes@adacore.com>
16845 Ed Schonberg <schonberg@adacore.com>
16846 Javier Miranda <miranda@adacore.com>
16848 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
16850 to check if a type is Constrained in cases related to code generation
16851 (rather than semantic checking) since otherwise we do not generate
16852 similar code for mutable private types depending if their
16853 discriminants are visible or not.
16854 (Check_Abstract_Overriding): Do not complain about failure to override
16855 the primitive operations used in dispatching selects since they will
16856 always be overriden at the freeze point of the type.
16857 (Access_Definition): Separate out handling for resetting the scope
16858 of an anonymous access function result type. Retrieve the scope
16859 of the associated function rather than using Current_Scope, which
16860 does not have a consistent value (depends on whether we're in the
16861 middle of analyzing formal parameters). Add ??? comment about
16862 finding a cleaner way to handle the special cases of scope setting.
16863 (Process_Incomplete_Dependents): A protected operation is never a
16864 dispatching operation (only its wrapper may be).
16865 (Build_Derived_Record_Type): In case of tagged private types that
16866 implement interfaces add derivation of predefined primitive
16868 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
16869 by two parameters that are used in case of derivation from abstract
16870 interface types: No_Predefined_Prims is used to avoid the derivation
16871 of predefined primitives from the interface, and Predefined
16872 Prims_Only is used to complete the derivation predefined primitives
16873 in case of private tagged types implementing interfaces.
16874 Fix typo in comments
16875 (Find_Interface_In_Descendant): Protect the frontend against
16876 wrong code with large circularity chains.
16877 (Is_Private_Overriding): Add support for entities overriding interface
16878 subprograms. The test failed because Entities associated with overriden
16879 interface subprograms are always marked as hidden (and used to build
16880 the secondary dispatch table); in this case the overriden entity is
16881 available through the field abstract_interface_alias (cf. override_
16882 dispatching_operation)
16883 (Access_Definition): Set the scope of the type to Current_Scope for the
16884 case of a function with an anonymous access result type.
16885 (Access_Subprogram_Declaration): Handle creation of the type entity for
16886 an access-to-function type with an anonymous access result.
16887 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
16888 in handling for N_Access_Function_Definition.
16889 (Analyze_Subtype_Declaration): Modify the text of error message.
16890 (Derived_Type_Declaration): Modify the text of error message.
16891 (Process_Subtype): Modify the text of error message plus cleanup
16892 of one redundant error message.
16893 (Analyze_Component_Declaration): Code cleanup.
16894 (Analyze_Object_Declaration): Code cleanup.
16895 (Analyze_Subtype_Declaration): Propagate the null-exclusion
16896 attribute in case of access types. Code cleanup.
16897 (Array_Type_Declaration): Code cleanup.
16898 (Process_Discriminants): Create the new null-excluding itype
16899 if required. Code cleanup.
16900 (Process_Subtype): Create the new null-excluding itype if
16901 required. Code cleanup.
16902 (Build_Derived_Record_Type): Code cleanup to avoid calling
16903 twice the subprogram derive_subprograms in case of private
16904 types that implement interfaces. In this particular case the
16905 subprogram Complete_Subprograms_Derivation already does the
16906 job associated with the second call.
16908 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
16909 conversion to the full view when generating an operation for a
16910 discriminant whose type may currently be private.
16912 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16913 Javier Miranda <miranda@adacore.com>
16915 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
16916 V (Obj.F), the rewriting does not involve the indexed component, but
16917 only the selected component itself.
16918 Do not apply the transformation if the analyzed node is an actual of a
16919 call to another subprogram.
16920 (Complete_Object_Operation): Retain the entity of the
16921 dispatching operation in the selector of the rewritten node. The
16922 entity will be used in the expansion of dispatching selects.
16923 (Analyze_One_Call): Improve location of the error message associated
16925 (Analyze_Selected_Component): No need to resolve prefix when it is a
16926 function call, resolution is done when parent node is resolved, as
16928 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
16929 when attempting to resolve a call transformed from its object notation.
16930 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
16931 of the argument list for each interpretation of the operation.
16932 (Try_Object_Operation): The designated type of an access parameter may
16933 be an incomplete type obtained through a limited_with clause, in which
16934 case the primitive operations of the type are retrieved from its full
16936 (Analyze_Call): If this is an indirect call, and the return type of the
16937 access_to_subprogram is incomplete, use its full view if available.
16939 2005-09-01 Javier Miranda <miranda@adacore.com>
16940 Gary Dismukes <dismukes@adacore.com>
16942 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
16943 access types the null-exclusion and access-to-constant attributes must
16945 (Analyze_Return_Statement): When the result type is an anonymous access
16946 type, apply a conversion of the return expression to the access type
16947 to ensure that appropriate accessibility checks are performed.
16948 (Analyze_Return_Type): For the case of an anonymous access result type,
16949 generate the Itype and set Is_Local_Anonymous_Access on the type.
16950 Add ??? placeholder for check to disallow returning a limited object
16951 in Ada 2005 unless it's an aggregate or a result of a function call.
16952 Change calls from Subtype_Mark to Result_Definition.
16953 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
16954 Result_Definition in call to Make_Function_Specification.
16955 (Build_Body_To_Inline): Change Set_Subtype_Mark to
16956 Set_Result_Definition.
16957 (Make_Inequality_Operator): Change formal Subtype_Mark to
16958 Result_Definition in call to Make_Function_Specification.
16959 (Process_Formals): Create the new null-excluding itype if required.
16960 (New_Overloaded_Entity): For an entity overriding an interface primitive
16961 check if the entity also covers other abstract subprograms in the same
16962 scope. This is required to handle the general case, that is, overriding
16963 other interface primitives and overriding abstract subprograms inherited
16964 from some abstract ancestor type.
16965 (New_Overloaded_Entity): For an overriding entity that comes from
16966 source, note the operation that it overrides.
16967 (Check_Conformance, Type_Conformant): Addition of one new formal
16968 to skip controlling formals in the analysis. This is used to
16969 handle overloading of abstract interfaces.
16970 (Base_Types_Match): Add missing case for types imported from
16971 limited-with clauses
16972 (New_Overloaded_Entity): Add barrier to protect the use of
16973 the "alias" attribute.
16975 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16977 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
16978 verify that the procedure and the entry are mode conformant.
16979 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
16980 as a different operator, which is often a cut-and-paste error.
16982 2005-09-01 Javier Miranda <miranda@adacore.com>
16983 Ed Schonberg <schonberg@adacore.com>
16985 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
16986 used in controlling parameters exclude null because it is necessary to
16987 read the tag to dispatch, and null has no tag.
16988 (Override_Dispatching_Operation): If the previous operation is inherited
16989 from an interface, it becomes hidden and does not participate in later
16992 2005-09-01 Javier Miranda <miranda@adacore.com>
16993 Ed Schonberg <schonberg@adacore.com>
16994 Gary Dismukes <dismukes@adacore.com>
16996 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
16997 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
16998 the expander will generate the corresponding run-time check to evaluate
17000 (Resolve_Call): Check for legal type of procedure name or prefix that
17001 appears as a trigger in a triggering alternative.
17002 (Valid_Conversion): If expression is ambiguous and the context involves
17003 an extension of System, remove System.Address interpretations.
17004 (Resolve_Qualified_Expression): Reject the case of a specific-type
17005 qualification applied to a class-wide argument. Enhance comment
17006 to explain checking of Original_Node.
17007 (Resolve_Type_Conversion): The location of the error message was not
17008 general enough to handle the general case and hence it has been removed.
17009 In addition, this patch improves the text of the message.
17010 (Resolve_Type_Conversion): Add missing support for access to interface
17012 (Resolve_Type_Conversion): If the target is a class-wide interface type,
17013 do not expand if the expression is the actual in a call, because proper
17014 expansion will take place when the call itself is expanded.
17015 (Resolve_Allocator): If the context is an unchecked conversion, the
17016 allocator inherits its storage pool, if any, from the target type of
17019 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17020 Javier Miranda <miranda@adacore.com>
17022 * sem_type.adb (Add_One_Interp): If a candidate operation is an
17023 inherited interface operation that has an implementation, use the
17024 implementation to avoid spurious ambiguities.
17025 (Interface_Present_In_Ancestor): In case of concurrent types we can't
17026 use the Corresponding_Record_Typ attribute to look for the interface
17027 because it is set by the expander (and hence it is not always
17028 available). For this reason we traverse the list of interfaces
17029 (available in the parent of the concurrent type).
17030 (Interface_Present_In_Ancestor): Handle entities from the limited view
17032 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17034 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
17035 from the list of required components.
17036 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
17037 primitive procedure of a limited interface with a controlling first
17039 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
17041 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
17042 capture if it is generated in the second operand of a short-circuit
17044 Do not capture values for variables with address clauses.
17045 (Is_Object_Reference): Treat a function call as an object reference only
17046 if its type is not Standard_Void_Type.
17048 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17050 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
17051 to a variable that is statically known to be constant.

17068 Document new treatment of wide characters in max line length
17070 Remove -gnatL/-gnatZ switches, no longer used.
17071 Add note on pragmas Assertion_Policy and Debug_Policy in discussion

17075 Float_Representation.
17076 Add documentation for pragma No_Strict_Aliasing

17833 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
17834 longer protected objects. They have been replaced by lower-level
17835 suspension objects made up by a mutex and a condition variable (or
17836 their equivalent given a particular OS) plus some internal data to
17837 reflect the state of the suspension object.
17838 (Initialize, Finalize): Add this initialization procedure for
17839 Suspension_Object, which is a controlled type.
17840 (Finalize): Add the finalization procedure for Suspension_Object,
17841 which is a controlled type.
17843 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

17860 set the environment task mask here.
17861 (Current_State): Add this function that returns the state of the
17863 (Set_False): Add this procedure that sets the state of the suspension
17865 (Set_True): Add this procedure that sets the state of the suspension
17866 object to True, releasing the task that was suspended, if any.
17867 (Suspend_Until_True): Add this procedure that blocks the calling task
17868 until the state of the object is True. Program_Error is raised if
17869 another task is already waiting on that suspension object.
17870 (Initialize): Add this procedure for initializing the suspension
17871 object. It initializes the mutex and the condition variable which are
17872 used for synchronization and queuing, and it sets the internal state
17874 (Finalize): Add this procedure for finalizing the suspension object,
17875 destroying the mutex and the condition variable.

17880 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
17881 which provides a low-level abstraction (using operating system
17882 primitives) for Ada.Synchronous_Task_Control.
17883 This object is made up by a mutex (for ensuring mutual exclusion), a
17884 condition variable (for queuing threads until the condition is
17885 signaled), a Boolean (State) indicating whether the object is open,
17886 and a Boolean (Waiting) reflecting whether there is a task already
17887 suspended on this object.

18152 type derivation of private tagged types implementing interfaces.
18153 In this case some interface primitives may have been overriden

18243 * i-cpp.ads, i-cpp.adb:
18244 This package has been left available for compatibility with previous
18245 versions of the frontend. As part of the new layout this is now a
18246 dummy package that uses declarations available at a-tags.ads
18248 * par-ch3.adb (P_Identifier_Declarations): Give an error for use of

18299 access to subprograms must be recursive.
18300 (Is_Unchecked_Conversion): Improve the test that recognizes
18301 instantiations of Unchecked_Conversion, and allows them in bodies that
18302 are to be inlined by the front-end. When the body comes from an

18326 Prevent the special checks for conversions of access discriminants in
18327 the case where the discriminant belongs to a nonlimited type, since
18328 such discriminants have their accessibility level defined in the same
18329 way as a normal component of an anonymous access type.
18330 (Resolve_Allocator): When an allocator's designated type is a class-wide
18331 type, check that the accessibility level of type given in the
18332 allocator's expression or subtype indication is not statically deeper

18351 constant-folded, there is nothing to check.
18352 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
18353 check on possible violation of restriction No_Direct_Boolean_Operators

18657 the "simple_choice" member in a variant record, in accordance with the
18658 description in the package spec: the information output for a constant
18659 should be "S number", not "SS number".
18660 (Get_Encoded_Name): Return at once if not generating code. Avoids name

19360 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

19363 error messages if expansion has been disabled due to previous
19364 (unrelated) errors).
19366 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
19367 is disabled, the entity denoted by the argument is the access type

19379 denotes a type in the class.
19380 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
19381 of Name_Generic_Dispatching_Constructor.
19383 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

19399 generic formal subprogram association for an abstract formal subprogram.
19400 Check that the attribute is a primitive stream attribute (and not
19401 a class-wide stream attribute) and then rewrite the attribute name
19402 as the name of the appropriate compiler-generated stream primitive.

19406 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

19414 itype whose parent is controlled and not yet frozen, do not create a
19415 freeze node for the itype if expansion is disabled.
19417 2005-03-29 Vincent Celier <celier@adacore.com>
19419 * make.adb (Gnatmake): Don't fail if the main project file is declared

20122 Update documentation on Must_Be_Byte_Aligned for new spec
20124 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
20125 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
20126 uses of the Access_Disp_Table attribute to reference the first dispatch
20127 table associated with a tagged type. As
20128 part of the implementation of abstract interface types,
20129 Access_Disp_Table has been redefined to contain a list of dispatch
20130 tables (rather than a single dispatch table).
20131 Similarly, upgrade all the references to Tag_Component by the
20132 new attribute First_Tag_Component.
20133 (Find_Inherited_TSS): Moved to exp_tss.

20141 Bit packed array ops are only called if operands are known to be
20143 (Component_Equality): When returning an N_Raise_Program_Error statement,
20144 ensure that its Etype is set to Empty to avoid confusing GIGI (which
20145 expects that only expressions have a bona fide type).
20146 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
20147 determine the amount of data to be copied.
20149 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
20150 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):

20177 (Task_Body_Procedure): Removed.
20178 (Set_Task_Body_Procedure): Removed.
20179 These subprogram have been removed because the attribute
20180 Task_Body_Procedure has been moved to the corresponding task type
20181 or task subtype entity to leave a field free to store the list
20182 of interfaces implemented by a task (for AI-345)
20183 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
20184 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
20185 expression flag Do_Range_Check

20201 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
20202 attribute Task_Body_Procedure rather than the old semantic field that
20203 was available in the task_type_declaration node.
20205 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
20206 interface type definitions.
20207 (P_Formal_Derived_Type_Definition): Modified to handle the list of
20210 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a

20247 expression to the type of the object when the object is constant.
20248 Reverse defer_debug_incomplete_list before traversing it, so that trees
20249 are processed in the order at which they were added to the list. This
20250 order is important when using the stabs debug format.
20251 If we are deferring the output of debug information, also defer this
20252 output for a function return type.
20253 When adding fields to a record, prevent emitting debug information
20254 for incomplete records, emit the information only when the record is
20256 (components_to_record): New parameter defer_debug.

20293 Expansion_Delayed and handle case when it's inside an
20294 N_Qualified_Expression.
20296 * sem_ch3.adb (Derived_Type_Declaration): New predicate
20297 Comes_From_Generic, to recognize accurately that the parent type in a
20298 derived type declaration can be traced back to a formal type, because
20299 it is one or is derived from one, or because its completion is derived
20301 (Constrain_Component_Type): If component comes from source and has no
20302 explicit constraint, no need to constrain in in a subtype of the
20304 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
20305 Minor change to propagate Is_Ada_2005 flag

20312 function returns "by target", dereference the target pointer using the
20313 type of the actual return value.
20314 <all>: Be prepared for a null gnu_result.
20315 (processed_inline_subprograms): Check flag_really_no_inline

20328 System.Pack_nn unit.
20330 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
20332 Needed now that we do some processing for IN parameters as well. This
20333 may well fix some unrelated errors.
20334 (Expand_Call): Handle case of unaligned objects (in particular those
20335 that come from packed arrays).
20336 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
20337 renamed entity is an inherited operation, re-expand the call using the
20338 original operation, which is the one to call.
20339 Detect attempt to inline parameterless recursive subprogram.
20340 (Represented_As_Scalar): Fix to work properly with private types
20341 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
20342 accurate estimate. Yields True in far fewer cases than before,
20343 improving the quality of code that depends on this test.
20345 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
20346 over both visible and private declarations to remove them from tree,
20347 and mark subprograms declared in package as eliminated, to prevent
20348 spurious use in subsequent compilation of generic units in the context.
20350 * exp_util.ads: Minor cleanup in variable names
20352 * sem_eval.ads, sem_eval.adb: Minor reformatting

20359 of an initialization call.
20361 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20363 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
20364 that appears in the instantiation rather than the internal subtype
20365 generated in the wrapper package, to avoid anomalies in gigi when the
20366 target is derived from a private type whose full view is an access type.
20368 2005-03-15 Robert Dewar <dewar@adacore.com>
20370 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,

20378 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
20379 here from exp_attr so it can be shared between exp_attr and exp_dist.
20380 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
20381 all TSS names, not a subset thereof, and the previous name introduced
20382 an unnecessarily confusion that a distinction might exist between
20383 "OK" TSS names and some "not OK" TSS names.
20385 2005-03-15 Doug Rupp <rupp@adacore.com>
20387 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
20390 2005-03-15 Pascal Obry <obry@adacore.com>
20391 Eric Botcazou <ebotcazou@adacore.com>
20395 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
20396 when IN_RTS. This is to work around a bootstrap path problem.
20398 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
20399 table and pass it to __gnat_install_SEH_handler().
20400 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.

20407 Arnaud Charlet <charlet@adacore.com>
20410 This change works fine when gnatlib is built from the gcc directory,
20411 but does not work when using the libada Makefile, since GCC_FOR_TARGET
20412 is not passed to ada/Makefile.in, so more work is needed by a
20413 Makefile/configure expert.
20415 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
20416 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
20417 Setup gnatlink switch -M for x86_64 linux, as it is already setup
20419 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
20420 Run ranlib on libgccprefix.a
20421 Define PREFIX_OBJS for Darwin, to build libgccprefix.
20422 (ADA_INCLUDE_SRCS): Split Ada packages.
20424 2005-03-15 Robert Dewar <dewar@adacore.com>
20426 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
20428 * impunit.adb: Add GNAT.UTF_32
20430 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
20432 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
20433 now uses GNAT.UTF_32).
20435 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
20436 capabilities for categorizing characters using Unicode categories
20438 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20440 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
20441 instantiation that has been rewritten as a package body, retrieve spec
20442 to generate proper name for implicit_with_clause.
20443 (Install_Parents): Recognize a parent that is an instantiation but has
20444 been rewritten as a package declaration during analysis.
20446 2005-03-15 Javier Miranda <miranda@adacore.com>
20447 Ed Schonberg <schonberg@adacore.com>
20449 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
20450 parameter reported some error we immediately return. This improves the
20451 behaviour of the frontend in case of errors.
20452 (Install_Parent, Remove_Parent): Introduce new flag
20453 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
20454 ancestor of a generic child unit, when the child is being instantiated.
20455 (Inline_Instance_Body): If we are compiling the private
20456 part or the body of a child unit, restore the proper visibility of the
20457 parents after compiling the instance body.
20459 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20460 Javier Miranda <miranda@adacore.com>
20463 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
20464 of a private type, in which case it is underlying_type that denotes
20465 the proper task. Also modified to use the new entity attribute
20466 that is directly available in the task type and task subtype entities
20467 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
20468 arrays when other dimensions than the first are constrained by
20469 discriminants of an enclosing record.
20470 (Insert_Explicit_Dereference): If the prefix is an indexed component or
20471 a combination of indexed and selected components, find ultimate entity
20472 and generate the appropriate reference for it, to suppress spurious
20474 (Note_Possible_Modification): If an entity name has no entity, return.
20475 (Is_Variable): A function call never denotes a variable.
20476 (Requires_Transient_Scope): For record types, recurse only on
20477 components, not on internal subtypes that may have been generated for
20478 constrained components.
20480 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20482 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
20483 Eliminated as candidates for resolution. Both efficient, and avoids
20484 anomalies with operators declared in deleted code.
20485 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
20486 expansion is disabled (as when compiling a generic) to prevent spurious
20487 warnings on prefixes of selected components.
20489 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20491 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
20492 attached to a list before checking whether it appears in the private
20493 declarations of the current package.
20494 (Make_Inequality_Operator): Insert declaration in proper declarative
20495 list rather than just setting the Parent field, so that
20496 Is_Private_Declaration can handle it properly.
20498 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20500 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
20501 a renaming a body, check that the renamed subprogram in not intrinsic.
20502 (Find_Direct_Name): If several use_visible entities hide
20503 each other, and the context is a predefined file compiled through
20504 rtsfind, keep only the entity that comes from a predefined file.
20506 2005-03-15 Geert Bosch <bosch@adacore.com>
20508 * s-fatgen.adb (Valid): Extend special exceptions to account for long
20509 long float padding to also cover AMD64 and IA64.
20511 2005-03-15 Gary Dismukes <dismukes@adacore.com>

20895 (Unit_Declaration_Node): Ditto.
20896 (Is_Variable_Prefix): For the case of an indexed component whose prefix
20897 has a packed array type, the prefix has been rewritten into a type

20903 * stringt.ads, stringt.adb: Handle full UTF-32 range.
20904 Remove ["0A"] from comment, since it can look like a line terminator.
20905 Currently we don't permit this, but this is under discussion by the
20906 ARG, and it is easy enough to use a different example.
20908 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
20909 handling UTF-32 encoding for wide wide character.

20928 wrong null-exclusion value by a warning message.
20929 (Enable_Range_Check): Do range check if the prefix is an

20967 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
20968 describing the new layout.
20969 (Dispatch_Table): The expander computes the actual array size, allocates
20970 the Dispatch_Table record accordingly, and generates code that displaces
20971 the base of the record after the Typeinfo_Ptr component. The access to
20972 these components is done by means of local functions.
20973 (Offset_To_Top): New function.
20974 (Typeinfo_Ptr): New function.
20975 (Get_TSD): Modified to access the new position of the TSD.
20976 (Set_TSD): Modified to save the TSD in its new position.

20986 N_Formal_Subtype_Declaration (which is now a subtype).
20987 (Analyze_Formal_Subprogram): Add handling for

20989 dispatching, setting the controlling status of the formal parameters
20990 and result, and issuing an error if there is no controlling type for
20991 the formal subprogram.
20992 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
20993 which is an unclean use of that field, we set the new field
20994 Corresponding_Formal_Spec to make the formal subprogram available to

21002 abstract formal subprograms in error check for functions returning
21003 abstract types. Set scope of new designator for

21005 body for nested subprograms, before full analysis of said body.
21006 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
21007 subprogram only if inner one comes from source.
21008 (Analyze_Function_Call): If the call is given in object notation, the

21010 argument list. After analyzing the name, if the call has been rewritten
21011 and the result type is set, no further analysis is needed.
21012 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
21013 mark in function specification, in a context where the formals are
21014 visible and hide outer homographs.
21016 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
21017 as the tagged type for the cases of abstract formal subprograms and
21018 renamings of those. Clean up spec comments.
21019 (Check_Dispatching_Context): Add error message to indicate "abstract
21020 procedure", covering the case of a call to a formal abstract procedure
21021 that has statically tagged operands.
21022 (Check_Dispatching_Call): Check for the case of an actual given by
21023 a tag-indeterminate function call whose type is an ancestor of the
21024 containing call's associated tagged type. This situation can occur
21025 for inherited primitives with function defaults. In this case we
21026 use the tagged type's tag directly as the controlling argument for
21028 (Expand_Call): Name change on call to Expand_Dispatch_Call.
21030 * sprint.adb (Sprint_Node_Actual): Split
21031 N_Formal_Subprogram_Declaration into two alternatives for the new

21107 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
21108 on the field if Pragma Component_Alignment (Storage_Unit).
21109 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
21110 side-effects as if it were a constant; also make SAVE_EXPR to protect

21130 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
21131 component of an array of arrays in an assignment context, and the
21132 aggregate has component associations that require sliding on
21133 assignment, force reanalysis of the aggregate to generate a temporary
21134 before the assignment.
21135 (Must_Slide): Make global to the package, for use in Gen_Assign.
21137 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21139 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
21140 unchecked union with no inferable discriminants, return a
21141 Raise_Program_Error node, rather than inserting it at the point the
21143 (Expand_Record_Equality, Component_Equality): Handle properly the case
21144 where some subcomponent is an unchecked union whose generated equality
21145 code raises program error.

21153 Arnaud Charlet <charlet@adacore.com>
21155 * init.c (__gnat_initialize): Add a new parameter eh which contains the
21156 address of the exception registration. The Win32 version of this
21157 routine calls __gnat_install_SEH_handler() to initialize the SEH
21158 (Structured Exception Handling) handler.
21159 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
21160 SEH (Structured Exception Handling) now.
21161 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
21162 (__gnat_initialize for ppc-vxworks): Adjust comments and the
21163 preprocessor condition protecting the call to the extra eh setup
21164 subprogram, which is only available for the ppc target.
21165 (__gnat_clear_exception_count): replaced reference to
21166 variable taskIdCurrent by call to taskIdSelf(), cleaner.
21168 * seh_init.c: New file.

21171 (GNATBIND_OBJS): Idem.
21173 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
21174 routine takes a new parameter (a pointer to the exception registration
21175 for the SEH (Structured Exception Handling) support.
21177 * raise.h: (__gnat_install_SEH_handler): New prototype.
21178 Update copyright notice.
21180 * s-tassta.adb (Task_Wrapper): Declare the exception registration

21210 2005-02-09 Vincent Celier <celier@adacore.com>
21212 * prj-makr.adb (Process_Directory): Put file name in canonical case
21213 before matching against the patterns.
21214 If gnatname has been invoked as <prefix>-gnatname
21215 then invoke the compiler as <prefix>-gcc, not just "gcc".
21217 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21219 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
21220 with expansion disabled. The actual subtype is needed among other
21221 places when the selected component appears in the context of a loop
21222 bound, and denotes a packed array.
21223 (Operator_Check): Always use the first subtype in the
21224 error message, to avoid the appearance of internal base types.
21225 (Transform_Object_Operation): Copy each actual in full
21226 to the parameter associations of the constructed call, rather than
21227 using the shallow copy mechanism of New_Copy_List. This ensures that
21228 the chaining of named associations is done properly.
21229 (Complete_Object_Operation): Rewrite node, rather than
21230 replacing it, so that we can trace back to the original selected
21233 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
21234 and calls that use object notation, if the called function is not
21235 declared in a withed unit, place the elaboration constraint on the
21236 unit in the context that makes the function accessible.
21237 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
21238 imposes an elaboration constraint between two packages.
21240 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21242 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
21243 views of a private type after handling its private dependents, to
21244 maintain proper stack discipline between entry and exit from the

21265 Slight fix to documentation of -gnaty with no parameters
21267 * xr_tabls.ads: Add ??? comment for missing overall comment
21269 * xsinfo.adb: Make default file name be sinfo.h, since this is what
21270 we now use by default.
21272 * xsnames.adb: Adjust end of file test to look for five space followed
21273 by '#' instead of six spaces. The format of xsnames.adb was modified
21274 in the last update.
21276 * a-numeri.ads: Add reference to AI-388 for greek letter pi
21279 * clean.adb: Minor reformatting.
21281 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
21282 gnatname.adb: Minor reformatting
21283 Add 2005 to copyright output when utility is run
21285 * csets.adb: Eliminate obsolete comment
21287 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
21290 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
21292 2005-02-09 Sergey Rybin <rybin@adacore.com>
21294 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
21295 the difference between compact and incompact layout and add the record
21296 representation clause to the example illustrating different layouts.
21297 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
21298 component clauses").
21300 2005-02-09 Florian Villoing <villoing@adacore.com>
21302 * gnat_ugn.texi: Fix typos.
21303 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
21305 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
21306 in the generated documentation.

21345 Use a pragma Elaborate_Body in the spec file instead.
21346 Noticed by code reading.
21348 2005-02-09 Thomas Quinot <quinot@adacore.com>
21350 * exp_util.ads: Minor correction in comment.
21352 2005-02-09 Arnaud Charlet <charlet@adacore.com>
21354 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
21355 since this procedure is now too complex to be worth inlining.

21605 is to check if two function signatures for a call-site and a callee are
21606 compatible enough for the call to be valid. The underlying purpose is
21607 to check if a call to a mapped builtin is using the right interface.
21608 The current code actually does not check antyhing - this a placeholder

21660 structure of GARLIC and PolyORB RPC receivers.
21661 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
21663 Simplify elaboration code for RCI packages.
21665 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

21775 note that it applies to obsolete GNAT features, which was previously
21776 omitted. Second we contrast the behavior with that of the new
21777 Ada 2005 AI-368 restriction No_Obsolescent_Features.
21778 Preliminary rewriting of GNAT & libraries chapter in order to take
21779 into account default project locations & new project manager

22011 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
22012 fields claimed addressable still have to be bitfields. Use
22013 value_factor_p instead of a raw binop construction to check for the
22014 position's alignment.

22021 Ed Schonberg <schonberg@adacore.com>
22023 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
22024 with an implicit dereference as its prefix, use
22025 Insert_Explicit_Dereference instead of merely rewriting the prefix into

22027 prefix is generated, if appropriate.
22029 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
22030 dereference is rewritten to an explicit one, generate a reference to

22033 access value, if appropriate.
22035 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
22036 emitting 'assigned but never read' warning on a variable on the basis

22050 an external name, to be handled by the back end.
22052 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
22053 subprogram which is Imported with convention Intrinsic if an
22054 External_Name argument is specified.
22055 (Process_Import_Or_Interface): Properly diagnose link name argument.

22112 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
22113 and the Has_Pragma_Unreferenced flag for each formal before analyzing
22114 the body, to ensure that warnings are properly emitted for each accept
22115 statement of a given task entry.

22143 (Remove_Next): Same cleanup
22145 2004-12-07 Thomas Quinot <quinot@adacore.com>
22147 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
22148 used to record an implicit dereference as a read operation on its
22149 prefix when operating under -gnatc. Necessary to avoid spurious
22150 'variable assigned but never read' warnings in that mode.
22151 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
22152 is a non-overloaded implicit dereference, call the above subprogram to
22153 ensure proper recording of references.
22155 2004-12-07 Gary Dismukes <dismukes@adacore.com>
22157 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

22207 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
22208 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
22209 and -eit to -ept. Added qualifier
22210 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
22212 2004-11-27 Andreas Schwab <schwab@suse.de>

22218 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
22219 internal implementation unit GNAT.Sockets.Thin,
22220 as their usage for sockets is non-portable (using the read and write
22221 functions from the system runtime library is fine on UNIX but won't

22278 new Others_Value and All_Others_Value objects.
22279 (struct attrib): Rename "arg" component as "args", since GCC expects a
22280 list of arguments in there.
22282 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
22283 corresponding objects exported by a-exexpr, instead of hardcoded dummy
22286 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
22287 others_decl and all_others_decl instead of hardcoded dummy addresses
22288 to represent "others" and "all others" choices, which is cleaner and
22289 more flexible with respect to the possible eh pointer encoding policies.
22291 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
22292 (process_attributes): Account for the naming change of the "args"
22293 attribute list entry component.
22295 * decl.c (build_attr_list): Rename into prepend_attributes to allow
22296 cumulating attributes for different entities into a single list.
22297 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
22298 attributes for the current entity and propagate first subtype
22299 attributes to other subtypes.
22300 <E_Procedure>: Attribute arguments are attr->args and not
22301 attr->arg any more.
22302 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
22303 argument provided, as this is what GCC expects. Use NULL_TREE instead
22306 2004-11-18 Robert Dewar <dewar@adacore.com>
22308 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

22341 (First_RCI_Subprogram_Id): Document this constant.
22342 (Add_RAS_Access_TSS): Correct the setting of the Etype of the

22345 replaced with calls to Get_Library_Unit_Name_String. Previously there
22346 were several instances of the same code in different locations in the
22347 compiler; this checkin completes the replacement of all of these
22348 instances with calls to a common subprogram.
22349 Minor reformatting.
22351 * sem_dist.adb: Remove comment noting that RPC receiver generation
22352 should be disabled for RACWs that implement RASs.
22353 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
22355 * sem_util.ads, sem_util.adb (Has_Stream): New function
22356 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
22357 qualified name of a library unit into the name buffer.
22358 (Note_Possible_Modification): Generate a reference only
22359 if the context comes from source.
22361 * snames.ads (PCS_Names): New subtype corresponding to names of
22362 supported implementations of the Partition Communication Subsystem
22363 (PCS) (i.e. the runtime library support modules for the distributed
22366 2004-11-18 Robert Dewar <dewar@adacore.com>
22367 Ed Schonberg <schonberg@adacore.com>
22369 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
22370 (Has_Rep_Pragma): New function
22371 (Has_Attribute_Definition_Clause): New function
22372 (Record_Rep_Pragma): Moved here from sem_ch13.adb
22373 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
22375 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
22377 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
22378 (Expand_Pragma_Psect_Object): New procedure
22379 These procedures contain the revised and cleaned up processing for
22380 these two pragmas. This processing was formerly in Sem_Prag, but
22381 is more appropriately moved here. The cleanup involves making sure
22382 that the pragmas are properly attached to the tree, and that no
22383 nodes are improperly shared.
22385 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
22386 pragmas to Exp_Prag, which is more appropriate.
22387 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
22388 check for duplicates Remove use of Is_Psected flag, no longer needed.
22389 Use new Make_String_Literal function with string.
22391 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
22392 that are functions return universal values, that have to be converted
22393 to the context type.
22394 Use new Make_String_Literal function with string.
22395 (Get_Stream_Convert_Pragma): New function, replaces the use of
22396 Get_Rep_Pragma, which had to be kludged to work in this case.
22398 * freeze.adb: Use new Has_Rep_Pragma function
22400 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
22401 function with string.
22402 Use new Has_Rep_Pragma function.
22404 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
22407 2004-11-18 Robert Dewar <dewar@adacore.com>
22409 * errout.ads, errout.adb: (First_Sloc): New function
22411 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
22412 check (-gnatyx) instead of being included as a redundant construct
22415 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
22416 Style_Check_Order_Subprograms.
22418 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
22419 stylesw.adb: Add Style_Check_Xtra_Parens
22421 * usage.adb: Add line for -gnatyx (check extra parens)
22423 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
22425 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22426 Robert Dewar <dewar@adacore.com>
22428 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
22429 discriminant of a constrained subtype, analyze the copy of the
22430 corresponding constraint, because in some cases it may be only
22431 partially analyzed.
22432 Removes long-lived ??? comments.
22434 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
22435 handled controlled or secondary-stack expressions within the
22436 iteration_scheme of a loop.
22438 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
22439 bounds that may contain functions calls, to prevent memory leaks when
22440 the bound contains a call to a function that uses the secondary stack.
22441 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
22442 generate temporaries for loop bounds that might contain function calls
22443 that require secondary stack and/or finalization actions.
22445 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
22446 selected component and the selector is overloadable (not just a
22447 function) treat as function call, Analyze_Call will disambiguate if
22449 (Analyze_Selected_Component): Do not generate an actual subtype for the
22450 selected component if expansion is disabled. The actual subtype is only
22451 needed for constraint checks.
22452 (Analyze_Allocator): If restriction No_Streams is set, then do
22453 not permit objects to be declared of a stream type, or of a
22454 composite type containing a stream.
22456 * restrict.ads: Remove the a-stream entry from Unit_Array, since
22457 No_Streams no longer prohibits with'ing this package.
22459 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
22460 discriminants, but the parent base has unknown discriminants, there is
22461 no discriminant constraint to inherit. Such a discrepancy can arise
22462 when the actual for a formal type with unknown discriminants is a
22463 similar private type whose full view has discriminants.
22464 (Analyze_Object_Declaration): If restriction No_Streams is set, then
22465 do not permit objects to be declared of a stream type, or of a
22466 composite type containing a stream.
22468 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22470 * exp_dbug.ads: Update documentation to reflect simpler encoding for
22471 protected operations.
22473 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
22474 generated name, it complicates decoding in gdb and hinders debugging
22475 of protected operations.
22476 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
22477 flag for the protected entry barrier function.
22478 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
22479 flag for the protected entry function.
22481 2004-11-18 Nicolas Setton <setton@adacore.com>
22483 * expect.c: Define __unix__ when __APPLE__ is defined.
22485 * Makefile.in: Inform the value of the variable GMEM_LIB in the
22486 Darwin-specific section.
22488 * lang-specs.h: Change the placement of the %1 marker.
22489 Works around the fact that gcc adds -fPIC by default under Darwin.
22491 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22493 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
22494 type of the object with the packed array type, set the Analyzed flag
22495 on the object if it is an entity or simple indexed component, to avoid
22496 spurious type errors.
22498 2004-11-18 Gary Dismukes <dismukes@adacore.com>
22500 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
22501 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
22502 separate line from the version message.
22504 2004-11-18 Ed Falis <falis@adacore.com>
22506 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
22508 (init_float): Eliminate initialization of floating point status for
22509 AE653. The instructions have no effect for vThreads.
22511 2004-11-18 Vincent Celier <celier@adacore.com>
22513 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
22514 gnatbind is invoked with -shared.
22516 2004-11-18 Jose Ruiz <ruiz@adacore.com>
22518 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
22519 for Detect_Blocking which is redundant with the check done within the
22520 procedure Protected_Single_Entry_Call.
22521 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
22522 Detect_Blocking which is redundant with the check done within the
22523 procedure Protected_Single_Entry_Call.
22525 2004-11-18 Vincent Celier <celier@adacore.com>
22527 * makegpr.adb (Compile): Put the compiling switches (in package
22528 Compiler and on the command line) immediately after "-c", instead of
22529 at the end of the command line invocation of the compiler, when
22530 compiling a non-Ada file.
22531 (Build_Global_Archive): When there is no need to rebuild the archive,
22532 set Global_Archive_Exists, so that the archive is passed to the linker
22535 2004-11-18 Robert Dewar <dewar@adacore.com>
22536 Sergey Rybin <rybin@adacore.com>
22539 Remove extra paren check from list of checks for redundant constructs
22540 Add documentation of new -gnatyx style check (check extra parens)
22541 Remove paragraph about gnatelim debug options.
22543 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
22544 objects rather than forbidding dependencies on the package Ada.Streams.
22546 * sinfo.ads: Add ??? note that we should document pragmas passed to
22549 * g-expect.ads: Fix a few typos in the comments.
22551 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
22553 * misc.c (gnat_handle_option): Use %< and %> for quoting in
22556 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
22558 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
22560 2004-11-07 Andreas Schwab <schwab@suse.de>
22562 * Makefile.in (install-gnatlib): Remove spurious hyphen.
22564 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
22567 * Makefile.in (darwin): Set soext to .dylib.
22569 2004-10-26 Vincent Celier <celier@gnat.com>
22570 Thomas Quinot <quinot@act-europe.fr>
22572 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
22573 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
22574 there is no use of GNAT.Sockets.Constants.
22575 Remove remaining pragma Import for C_Write
22576 Remove C_Read and C_Write from internal implementation unit
22577 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
22578 the read and write functions from the system runtime library is fine
22579 on UNIX but won't work under Windows).
22581 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
22582 (Check_Selector): Use C_Recv instead of C_Read.
22583 Selectors are the GNAT.Sockets abstraction to perform a select()
22584 call on a set of descriptors. To allow abortion of an ongoing
22585 select operation, some data is written to a dedicated socket that
22586 is always monitored.
22587 Under Windows, the write and read library functions cannot operate
22588 on sockets, so we need to use send and recv instead, which is portable
22589 across all supported platforms.
22591 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
22592 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
22593 (using the read and write functions from the system runtime library is
22594 fine on UNIX but won't work under Windows).
22596 2004-10-26 Nicolas Setton <setton@act-europe.fr>
22598 * mlib-tgt-darwin.adb: New file.
22600 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
22601 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
22602 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
22603 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
22606 * Makefile.in: Add support for building shared libraries under Darwin.
22607 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
22608 the low level EH init subprogram to be called from __gnat_initialize.
22610 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
22611 indicates which options to pass to the archive indexer.
22613 * mlib-utl.adb: Add support for calling ranlib with additional
22614 options. This is needed for instance under Mac OS X.
22615 (Ranlib_Options): New global variable, used to store the potential
22616 options to pass to ranlib.
22617 (Ar): Use Ranlib_Options when spawning ranlib.
22618 (Initialize): Set the value of ranlib option.
22620 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
22622 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
22623 instead of 8K, to reflect the real potential needs for stack-checking
22626 2004-10-26 Pascal Obry <obry@gnat.com>
22628 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
22630 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
22631 Windows only the initial thread stack size can be set so it is good to
22632 start we a low stack size.
22633 The OS will adjust the size as needed.
22635 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
22636 Nicolas Setton <setton@act-europe.fr>
22638 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
22639 "__unix__" instead of "unix".
22640 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
22641 sections were just mistakenly ignored. The former is
22642 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
22643 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
22644 of hpux. This prevents an unwanted definition of the symbol
22645 convert_addresses in adaint.o.
22647 2004-10-26 Gary Dismukes <dismukes@gnat.com>
22649 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
22650 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
22652 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22654 * a-filico.ads, a-filico.adb: fix incorrect header.
22656 2004-10-26 Javier Miranda <miranda@gnat.com>
22658 * a-ststio.ads: Fix typo in identifier
22660 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22662 * sem_ch4.adb: Minor reformatting.
22664 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22666 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
22667 enabled, check the result of unary and binary operations when the
22668 expression is the right-hand side of an assignment.
22670 2004-10-26 Vincent Celier <celier@gnat.com>
22672 * clean.adb (Delete): Do not output warnings when in quiet output and
22673 not in verbose mode.
22674 (Force_Deletions): New Boolean flag, defaulted to False
22675 (Delete): Only delete a file if it is writable, and when
22676 Force_Deletions is True.
22677 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
22678 (Usage): Line for new switch -f
22679 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
22682 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
22684 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
22685 JM type only if its size matches that of the wrapper. When a size is
22686 prescribed and the field is not aliased, remove the wrapper of a JM
22687 type only if the size is not greater than that of the packed array.
22688 (gnat_to_gnu_entity): Change the extension of packed array wrappers
22691 2004-10-26 Geert Bosch <bosch@gnat.com>
22693 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
22694 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
22695 (Pred): Implement in terms of Succ.
22697 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22699 * exp_aggr.adb (Safe_Component): An aggregate component that is an
22700 unchecked conversion is safe for in-place use if the expression of the
22701 conversion is safe.
22702 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
22703 be expandable in place even if the aggregate does not come from source.
22704 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
22705 designated object of an allocator in place, rather than building it
22706 first on the stack. The previous scheme forces a full copy of the array,
22707 and may be altogether unsusable if the size of the array is too large
22708 for stack allocation.
22710 2004-10-26 Robert Dewar <dewar@gnat.com>
22712 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
22713 compares if the component is atomic.
22715 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
22716 array assignment if the component type is atomic.
22718 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22719 Eric Botcazou <ebotcazou@act-europe.fr>
22721 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
22722 is aliased and is a by_reference type, do not pass by copy.
22723 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
22724 detect whether the call is in the right side of an assignment or
22725 the expression of an object declaration. Recurse on component
22726 association within aggregates.
22727 Call it in the condition that determines whether the temporary is
22728 necessary for correct stack-checking.
22730 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22732 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
22733 RACW_Type, used in the PolyORB version.
22734 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
22735 version and the GARLIC version.
22737 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
22738 Rename RCI_Info to RCI_Locator for better consistency between the
22739 GARLIC and PolyORB versions of the distributed systems annex.
22740 (DSA_Implementation_Name): This enumeration lists the possible
22741 implementations of the Partition Communication Subsystem for the
22742 Distributed Systems Annex (DSA). The three available implementations
22743 are the dummy stub implementation (No_DSA), and two versions based on
22744 two different distribution runtime libraries: GARLIC and PolyORB. Both
22745 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
22747 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
22750 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
22751 between the GARLIC and PolyORB versions of the distributed systems
22753 Remove RE_Unbounded_Reclaim_Pool since it is unused.
22755 2004-10-26 Gary Dismukes <dismukes@gnat.com>
22757 * gnat1drv.adb: Suppress calling the back end when
22758 Frontend_Layout_On_Target is true.
22760 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22762 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
22763 Set_Read_Only): New subprograms.
22764 These new routines allow the user to set or unset the Owner execute
22765 and Owner write permission flags on a file.
22767 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
22768 GNAT.OS_Lib.Set_Executable instead of rolling our own.
22770 2004-10-26 Matthew Gingell <gingell@gnat.com>
22772 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
22774 2004-10-26 Pascal Obry <obry@gnat.com>
22776 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
22777 memory before the faulting page we properly test the process read
22778 access for this address using appropriate Win32 routine.
22779 (HPUX sections): guard with "__hpux__" instead of "hpux".
22781 2004-10-26 Robert Dewar <dewar@gnat.com>
22783 * lib-xref.adb (Generate_Reference): Don't complain about reference to
22784 entry parameter if pragma Unreferenced set, since we do not properly
22785 handle the case of multiple parameters.
22787 2004-10-26 Vincent Celier <celier@gnat.com>
22789 * prj-env.adb: (Contains_ALI_Files): New Boolean function
22790 (Ada_Objects_Path.Add): For a library project, add to the object path
22791 the library directory only if there is no object directory or if the
22792 library directory contains ALI files.
22793 (Set_Ada_Paths.Add.Recursive_Add): Ditto
22795 2004-10-26 Vincent Celier <celier@gnat.com>
22797 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
22798 extension of library projects.
22800 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
22801 path defaults to ".:<prefix>/lib/gnat".
22802 (Parse): For an extending all project, allow direct import of a project
22803 that is virtually extended.
22805 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
22806 the specified name is directly imported, return its ID. Otherwise, if
22807 an extension of this project is imported, return the ID of the
22810 2004-10-26 Robert Dewar <dewar@gnat.com>
22812 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
22813 (Sub3): New procedure, used by Scaled_Divide
22814 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
22815 correct more than one instance of failure to propagate carries
22817 (Double_Divide): Handle overflow case of largest negative number
22818 divided by minus one.
22820 * s-arit64.ads (Double_Divide): Document that overflow can occur in
22821 the case of a quotient value out of range.
22824 2004-10-26 Robert Dewar <dewar@gnat.com>
22826 * s-bitops.adb (Bit_Eq): Remove redundant check.
22828 * s-bitops.ads: Minor comment updates
22829 Change some occurrences of Address to System.Address
22831 * s-carsi8.ads: Fix minor cut-and-paste error in comments
22833 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22835 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
22836 accessibility check to prefix that is a protected operation.
22838 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22840 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is

22844 Javier Miranda <miranda@gnat.com>
22846 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
22847 current instance appears within a unit that is directly in the context
22849 Used to determine whether the body of the instance should be analyzed
22850 immediately after its spec, to make its subprogram bodies available
22851 for front-end inlining.
22852 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
22853 constraint is not allowed on the component type (AARM 12.5.3(3))
22855 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22857 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
22858 'Storage_Pool): enhance, document & limit detection of non-sharable
22861 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
22863 * s-pooglo.ads: Add more documentation now that this pool is properly
22866 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22868 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
22869 or protected type with discriminants, do not constrain the
22870 corresponding record type if the subtype declaration has no
22871 discriminant constraints. This can be the case in source code, or in
22872 the subtype declaration created to rename an actual type within an
22875 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22877 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
22878 different kind of stub (possibly wrong name for file), do not check
22880 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
22881 includes call to some function that returns an unconstrained type, do
22884 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22886 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
22887 appear in the code for the main unit. Dependencies among units in the
22888 context of the main unit are established when those other units are
22889 compiled. Otherwise spurious elaboration constraints can generate
22890 incorrect elaboration circularities.
22892 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22893 Ed Schonberg <schonberg@gnat.com>
22895 * sem_util.adb (Is_Aliased_View): Defend against the case where this
22896 subprogram is called with a parameter that is not an object name. This
22897 situation arises for some cases of illegal code, which is diagnosed
22898 later, and in this case it is wrong to call Is_Aliased, as that might
22899 cause a compiler crash.
22900 (Explain_Limited_Type): Refine previous fix to include
22901 inherited components of derived types, to provide complete information.
22903 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
22904 is the prival for a protected object.
22905 It is necessary to mark this entity as a variable, in addition to
22906 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
22907 modified to avoid checking the Aliased flag on entities that are not
22908 objects. (Checking that flag for non-objects is erroneous and could
22909 lead to a compiler crash).
22911 2004-10-26 Robert Dewar <dewar@gnat.com>
22913 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
22914 X_Frac = 0.5, then we know that the number X must be positive.
22915 (Succ): Remove the same redundant test, and also fix the primary test
22916 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
22918 (Decompose): Add fuller comments to spec
22920 2004-10-26 Pascal Obry <obry@gnat.com>
22922 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
22923 validity (process must have read access). Set to 0 in all other cases.
22924 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
22925 violation on Win32.
22926 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
22927 segmentation violation.
22929 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
22931 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
22932 whose type is a constructed subtype of an aliased object with an
22933 unconstrained nominal subtype, convert the actual to the constructed
22934 subtype before taking its address.
22936 2004-10-26 Vincent Celier <celier@gnat.com>
22938 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
22939 (Is_Path_Name_Case_Sensitive): New function
22941 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
22942 (Base_Name, Simple_Name, Current_Directory, Compose,
22943 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
22946 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22947 Vasiliy Fofanov <fofanov@act-europe.fr>
22948 Vincent Celier <celier@gnat.com>
22950 * gnat_ugn.texi: Generalize "finding memory problems" section into a
22951 "memory management issues" section and document some of the useful
22952 memory pools provided as part of the GNAT library.
22953 Remove "virtual" from declaration of A::method2 in
22954 the simple example of Ada/C++ mixed system.
22955 Library Projects may be virtually extended: their virtual extensions
22956 are not Library Projects.
22957 Added section on extending project hierarchies.
22959 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
22961 * adaint.c (__gnat_get_libraries_from_registry): Cast value
22963 (__gnat_portable_spawn): Remove const.
22965 * mingw32.h (MAXPATHLEN): Check for previous definition.
22967 2004-10-17 Matthias Klose <doko@debian.org>
22969 * gnatvsn.ads: Set gnat library version to 4.0.
22971 2004-10-05 Vincent Celier <celier@gnat.com>
22973 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
22975 2004-10-04 Laurent GUERBY <laurent@guerby.net>
22978 * Makefile.in: Define and use RANLIB_FLAGS.
22980 2004-10-04 Pascal Obry <obry@gnat.com>
22982 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
22983 other x86 platforms).
22985 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
22987 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
22988 in general and triggers stack alignment adjustment for thread entry
22989 points on targets where this is necessary.
22991 2004-10-04 Bernard Banner <banner@gnat.com>
22994 * Makefile.in: Add section for powerpc linux
22995 Add variant i-vxwork-x86.ads
22997 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
22999 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
23001 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
23002 table registration calls when need be. Ensures no reference to the crt
23003 ctors symbol are issued in the SJLJ case, which avoids possible
23004 undefined symbol errors in the case of modules to be statically linked
23007 2004-10-04 Javier Miranda <miranda@gnat.com>
23009 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
23010 in-line the code corresponding to subprogram Analyze_Actuals. In
23011 addition, analyze the actuals only in case of subprogram call.
23013 2004-10-04 Ed Falis <falis@gnat.com>
23015 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
23017 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
23019 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
23020 in the documentation.
23022 2004-10-04 Robert Dewar <dewar@gnat.com>
23024 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
23026 (Analyze_Block_Statement): Add circuitry to detect following dead code
23027 (Check_Unreachable_Code): Handle case of block exit
23029 2004-10-04 Robert Dewar <dewar@gnat.com>
23031 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
23032 (XMatchD): Avoid warning for Logic_Error call
23034 2004-10-04 Robert Dewar <dewar@gnat.com>
23036 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
23037 consider expressions buried within a procedure actual to be an actual.
23038 This caused some blowups with uses of packed slices within a procedure
23041 2004-10-04 Robert Dewar <dewar@gnat.com>
23043 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
23044 longer need to be initialized to zero.
23045 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
23046 initialized to zero.
23048 * checks.adb (Expr_Known_Valid): Packed arrays are now always
23049 considered valid, even if the representation is modular. That's correct
23050 now that we no longer initialize packed modular arrays to zero.
23052 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
23053 suffixes. These are now documented as the only cases in which the
23054 debugger ignores outer records.
23055 Previously, the spec allowed arbitrary suffixes for this purpose.
23056 Change name of LJM to JM for packed array pad records
23057 Create separate section on packed array handling, and add a whole new
23058 set of comments to this section describing the situation with packed
23059 modular types and justification requirements depending on endianness.
23061 2004-10-04 Robert Dewar <dewar@gnat.com>
23063 * a-except.adb: Add a comment for last change
23065 * einfo.ads: Minor spelling correction in comment
23067 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
23069 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
23072 * sem_util.ads: Minor comment update
23074 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23076 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
23077 Inline_Always when in Configurable_Run_Time mode.
23079 * sem_prag.adb (Process_Convention): If entity is an inherited
23080 subprogram, apply convention to parent subprogram if in same scope.
23081 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
23082 when in Configurable_Run_Time mode.
23084 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23086 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
23087 class_wide type after component list has been inherited.
23089 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23091 * sem_ch12.adb (Check_Generic_Actuals): New predicate
23092 Denotes_Previous_Actual, to handle properly the case of a private
23093 actual that is also the component type of a subsequent array actual.
23094 The visibility status of the first actual is not affected when the
23095 second is installed.
23096 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
23097 make fully recursive the treatment of formals of packages declared
23099 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
23100 the above on exit from an instantiation.
23101 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
23102 current instantiation which is now complete.
23103 (Analyze_Package_Instantiation): No instantiated body is needed if the
23104 main unit is generic. Efficient, and avoid anomalies when a instance
23105 appears in a package accessed through rtsfind.
23107 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23109 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
23110 do not generate a declaration for a temporary if the call is part of a
23111 library-level instantiation.
23113 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23115 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
23116 searching for a limited component to flag.
23118 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
23119 expansion of Input, to account for the fact that the implicit call
23120 generated by the attribute reference must freeze the user-defined
23121 stream subprogram. This is only relevant to 'Input, because it can
23122 appear in an object declaration, prior to the body of the subprogram.
23124 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
23125 expansion can proceed and further errors uncovered.
23126 (Minor clean up): Fix cases of using | instead of \ for continuation
23129 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
23131 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
23133 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
23134 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
23135 Use gcc_assert and gcc_unreachable.
23137 * decl.c (gnat_to_gnu_entity, case object): Check and process a
23138 specified alignment before validating size.
23139 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
23140 stripped-down declaration for the type of the inner field when making
23143 * utils.c (finish_record_type): Do not compute the size in units
23144 incrementally. Instead compute it once for the rep clause case.
23145 Use gcc_assert and gcc_unreachable.
23147 2004-10-04 Vincent Celier <celier@gnat.com>
23149 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
23151 (Is_Valid_Path_Name): Take '/' as a directory separator.
23153 2004-10-04 Vincent Celier <celier@gnat.com>
23155 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
23156 (Extended_Project) only if Extended_Project is defined, to avoid
23158 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
23160 (Parse_Single_Project): Ditto.
23162 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
23163 Add_To_Project_Path for virtual projects.
23165 2004-10-04 Vincent Celier <celier@gnat.com>
23167 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
23168 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
23169 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
23170 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
23171 parameter Options_2.
23173 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
23174 Build_Dynamic_Library with an empty Options_2.
23176 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
23179 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
23180 directory separator, if any.
23181 (Gprmake): Do not allow mains on the command line for library projects.
23182 Do not attempt to link when the project is a library project.
23183 (Library_Opts): New table to store Library_Options.
23184 (Build_Library): If Library_Options is specified, pass these options
23185 when building a shared library.
23187 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
23189 * s-tposen.adb (Service_Entry): The object must be always unlocked at
23190 the end of this procedure now that the unlock operation was inserted
23193 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
23195 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
23196 corresponding to the Preallocated_Stacks flags in System.
23197 (Get_Target_Parameters): Including the processing for
23198 Preallocated_Stacks.
23200 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
23201 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,
23202 system-freebsd-x86.ads, system-lynxos-ppc.ads, system-lynxos-x86.ads,

23208 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
23209 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
23210 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
23211 used to signal whether the compiler creates the required stacks and
23212 descriptors for the different tasks (when True) or it is done by the
23213 underlying operating system at run time (when False).
23214 It is initially set to False in all targets.
23216 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
23217 if it is supported by the target.
23218 (Make_Task_Create_Call): Pass the stack address if it has been
23219 previously created. Otherwise pass a Null_Address.
23221 * snames.adb: Add _stack.
23223 * snames.ads: Add Name_uStack. Required to allow the expander to
23224 statically allocated task stacks.
23226 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
23227 Stack_Address argument.
23228 Check that its value is equal to Null_Address because this target does
23229 not support the static stack allocation.
23231 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
23233 * usage.adb: Change "pragma inline" to "pragma Inline" in information
23236 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
23238 * exp_dist.adb: Split declaration of asynchronous flag out of
23239 Add_RACW_Read_Attribute.
23240 Minor reformatting for better alignment with PolyORB version.
23241 Store the entity for the asynchronous flag of an RACW, rather than the
23242 expression, in the asynchronous flags table. This will allow this flag
23243 to be used in other subprograms beside Add_RACW_Read_Attribute.
23245 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
23247 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
23248 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
23249 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
23250 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
23251 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
23252 sockets constant MSG_NOSIGNAL (Linux-specific).
23253 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
23254 all Send operations.
23255 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
23256 from trigerring SIGPIPE.
23257 Rename components to avoid clash with Ada 2005 possible reserved
23259 (Check_Selector): When the select system call returns with an error
23260 condition, propagate Socket_Error to the caller.
23262 2004-10-01 Jan Hubicka <jh@suse.cz>
23264 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
23266 2004-09-23 Robert Dewar <dewar@gnat.com>
23269 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
23270 instead do this at freeze time (we won't do it if there is an address
23272 Change "pragma inline" to "pragma Inline" in information and error
23274 Minor reformatting.
23276 * freeze.adb (Check_Address_Clause): Remove previous change, not the
23277 right way of doing things after all.
23278 (Freeze_Entity): For object, set Is_Public for imported entities
23279 unless there is an address clause present.
23281 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
23283 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
23284 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
23285 ensures proper handling of types with rep clauses, which might have
23286 their TYPE_SIZE set already.
23288 2004-09-21 Robert Dewar <dewar@gnat.com>
23290 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
23291 packed array types in both little- and big-endian cases. This change
23292 ensures that we no longer count on the unused bits being initialized
23293 for such types (and in particular ensures that equality testing will
23294 only read the relevant bits).
23295 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
23296 These changes mean that we no longer need to initialize small packed
23298 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
23299 optimization to an LJM field as to its parent field.
23301 * ada-tree.h, trans.c, utils.c, utils2.c:
23302 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
23304 2004-09-20 Jan Hubicka <jh@suse.cz>
23306 * utils.c (gnat_finalize): Remove.
23307 (end_subprog_body): Directly call cgraph_finalize_function;
23308 do not lower the nested functions.
23310 2004-09-20 Robert Dewar <dewar@gnat.com>
23313 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
23314 if an address clause is present, since that means that the Import
23317 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
23319 * 5tsystem.ads: Removed, no longer used.
23321 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
23322 Zack Weinberg <zack@codesourcery.com>
23324 * ada-tree.def: Use tree_code_class enumeration constants
23325 instead of code letters.
23326 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
23327 Update for new tree-class enumeration constants.
23329 2004-09-17 Vincent Celier <celier@gnat.com>
23331 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
23332 capabilities of the general project manager.
23334 2004-09-09 Vincent Celier <celier@gnat.com>
23336 * a-direct.ads: Add pragma Ada_05

23426 raise Program_Error if called from a protected operation.
23428 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
23429 the protected action nesting level.
23430 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
23431 protected action nesting level.
23432 (Unlock): When pragma Detect_Blocking is active decrease the protected
23433 action nesting level.
23435 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
23436 Protected_Action_Nesting.
23438 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
23439 Common_ATCB record. It contains the dynamic level of protected action
23440 nesting for each task. It is needed for checking whether potentially
23441 blocking operations are called from protected operations.
23442 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
23443 Detect_Blocking is active or not in the partition.
23445 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

23479 contains the required machinery for handling that.
23481 * sem_util.ads: Change comment associated to procedure
23482 Check_Potentially_Blocking_Operation.
23483 This procedure does not insert a call for raising the exception because
23484 that is currently done by the run time.
23486 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
23488 * init.c: Add the global variable __gl_detect_blocking that indicates
23489 whether pragma Detect_Blocking is active (1) or not (0). Needed for
23490 making the pragma available at run time.
23491 (__gnat_set_globals): Pass and update the detect_blocking parameter.

23498 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
23499 DB is found in the ali file. Any unit compiled with pragma
23500 Detect_Blocking active forces its effect in the whole partition.
23502 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
23503 Detect_Blocking is active and delay is called from a protected
23506 * bindgen.adb (Gen_Adainit_Ada): When generating the call to

23520 (Register_Receiving_Stub): Add Subp_Info formal parameter.
23521 Update API in placeholder implemetation of s-parint to reflect changes
23522 in distribution runtime library.
23524 * sem_ch3.adb (Expand_Derived_Record): Rename to
23525 Expand_Record_Extension.
23527 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
23528 primitive operations of potentially distributed object types that have
23529 non-controlling anonymous access formals.
23531 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
23533 New implementation of expansion for remote access-to-subprogram types,
23534 based on the RACW infrastructure.
23535 This version of sem_dist is compatible with PolyORB/DSA as well as
23538 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
23539 Asynchrronous that applies to a remote access-to-subprogram type, mark
23540 the underlying RACW type as asynchronous.
23542 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
23543 __gnat_using_gnu_linker to 1.

23554 (Build_Record_Init_Proc.Build_Assignment): The default expression in
23555 a component declaration must remain attached at that point in the
23556 tree so New_Copy_Tree copies it if the enclosing record type is derived.
23557 It is therefore necessary to take a copy of the expression when building
23558 the corresponding assignment statement in the init proc.
23559 As a side effect, in the case of a derived record type, we now see the
23560 original expression, without any rewriting that could have occurred
23561 during expansion of the ancestor type's init proc, and we do not need
23562 to go back to Original_Node.
23564 * exp_ch3.ads (Expand_Derived_Record): Rename to
23565 Expand_Record_Extension.
23567 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

23572 subprogram. The proxy object is used as the designated object
23573 for RAS values on the same partition (unless All_Calls_Remote applies).
23574 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
23575 System.Partition_Interface.Get_Unique_Remote_Pointer.

23580 New implementation of expansion for remote access-to-subprogram types,
23581 based on the RACW infrastructure.
23583 * exp_dist.ads (Copy_Specification): Update comment to note that this
23584 function can copy the specification from either a subprogram
23585 specification or an access-to-subprogram type definition.
23587 2004-09-09 Ed Schonberg <schonberg@gnat.com>
23589 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
23590 in an instance, between an explicit subprogram an one inherited from a
23591 type derived from an actual.
23593 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
23594 add a polling call if the subprogram is to be inlined by the back-end,
23595 to avoid repeated calls with multiple inlinings.
23597 * checks.adb (Apply_Alignment_Check): If the expression in the address
23598 clause is a call whose name is not a static entity (e.g. a dispatching
23599 call), treat as dynamic.

23603 * g-trasym.ads: Minor reformatting
23605 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

23614 2004-09-09 Pascal Obry <obry@gnat.com>
23616 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
23617 enable map file generation. Add the right option to generate the map
23618 file if Map_File is set to True.
23620 * gnatdll.adb (Gen_Map_File): New variable.
23621 (Syntax): Add info about new -m (Map_File) option.

23649 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
23650 of variable length temporaries for function return now that the
23651 back-end and gigi support it.

23728 consistent treatment of entity references contained within the
23729 enclosed procedure call.
23731 2004-09-01 Vincent Celier <celier@gnat.com>
23733 * bindgen.adb: (Set_EA_Last): New procedure

23820 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
23821 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
23822 option and not mdll anymore. Update comment.
23824 2004-08-16 Pascal Obry <obry@gnat.com>

23908 returning C.int, to avoid using a derived boolean type.
23910 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

25793 2004-06-07 Thomas Quinot <quinot@act-europe.fr>
25795 * bindgen.adb (Set_Unit_Number): Units is an instance of Table, and so
25796 the index of the last element is Units.Last, not Units.Table'Last

25798 storage for the table).
25800 * exp_ch4.adb (Insert_Dereference_Action): Change predicate that
25801 determines whether to generate a call to a checked storage pool

25835 hand side. Warnings are now properly emitted when variables or prefixes
25836 are assigned but not read.
25838 * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
25839 left hand side referenced variables. Private access types do not

25863 interpretations for rewritten right operand.
25864 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

26290 * sem_ch4.adb (Analyze_Selected_Component): If prefix is a protected
26291 subtype, check visible entities in base type.
26293 * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
26294 actions if the object is a renaming.
26296 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
26297 Check_Formal_Package_Instance, to determine more precisely when the
26298 formal and the actual denote the same entity.
26300 2004-05-14 Javier Miranda <miranda@gnat.com>
26302 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
26304 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
26305 corresponding to a private_with must be removed from visibility; it
26306 will be made visible later, just before we analyze the private part of
26308 (Check_Private_Child_Unit): Allow private_with clauses in public
26310 (Install_Siblings): Make visible the private entities of private-withed
26312 (Install_Withed_Unit): Do not install the private withed unit if we
26313 are compiling a package declaration and the Private_With_OK flag was
26314 not set by the caller. These declarations will be installed later,
26315 just before we analyze the private part of the package.
26317 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
26318 during the evaluation of the expression that initializes the object,
26319 decorate it with the expected type to avoid cascade errors.
26322 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
26323 subprogram we have to install the private_with clauses after its
26324 specification has been analyzed (as documented in AI-262.TXT).
26326 * sem_ch8.adb (Has_Private_With): New function. Determines if the
26327 current compilation unit has a private with on a given entity.
26328 (Find_Direct_Name): Detect the Beaujolais problem described in
26331 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
26332 provides the functionality of the function Is_Ancestor that was
26333 previously available in sem_ch10. It has been renamed to avoid
26336 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
26338 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26340 * utils.c (build_vms_descriptor): Use SImode pointers.

26500 Merge from tree-ssa-20020619-branch.
26502 * config-lang.in (boot_language, build_by_default): Set

26519 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
26522 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
26524 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
26526 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
26527 Fixes undefined symbols in IA64 gnatlib.
26529 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
26531 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
26532 Short_Address). This will be moved to system.auxdec.

26536 * sem_util.adb: Replace test for presence of a node that is always
26537 present with a call to Discard_Node.
26539 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
26540 Analyze on the library unit node after generation of distribution stub
26541 constructs. The call was a no-op because Unit_Node has already been
26542 Analyzed, and the tree fragments for the distribution stubs are
26543 analyzed as they are inserted in Exp_Dist.
26544 Update comment regarding to distribution stubs to reflect that we
26545 do not generate stub in separate files anymore.
26547 * einfo.ads: Clarify the fact that a tagged private type has the
26548 E_Record_Type_With_Private Ekind.
26550 * erroutc.adb: Minor reformatting
26552 * erroutc.ads (Max_Msg_Length): Increase to cover possible larger
26553 values if line length is increased using -gnatyM (noticed during code

26559 2004-05-10 Ed Schonberg <schonberg@gnat.com>
26562 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
26563 has been rewritten as an explicit dereference, retrieve type of
26564 original node to check for possibly unconstrained record type.
26566 2004-05-10 Ed Schonberg <schonberg@gnat.com>
26568 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
26569 overriding, use the operation of the parent unconditionally.
26571 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
26572 operation when either operand is a literal, to avoid further
26575 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
26576 overridden by a previous explicit declaration, mark the previous entity
26579 * sem_disp.adb (Check_Dispatching_Operation): New predicate
26580 Is_Visibly_Controlled, to determine whether a declaration of a
26581 primitive control operation for a derived type overrides an inherited
26582 one. Add warning if the explicit declaration does not override.
26584 2004-05-10 Vincent Celier <celier@gnat.com>
26586 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
26587 some cases when the sources are no longer present.
26589 * make.adb (Collect_Arguments): Fail if an external source, not part
26590 of any project need to be compiled, when switch -x has not been
26593 * makeusg.adb: Document new switch -x
26595 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
26596 defaulted to False.
26598 * switch-m.adb (Scan_Make_Switches): New switch -x
26600 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
26601 gnatmake switch -x.
26603 * gnat_ugn.texi: Document new gnatmake switch -x
26605 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
26607 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
26609 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
26610 (process_attributes): Likewise.
26612 2004-05-10 Joel Brobecker <brobecker@gnat.com>
26614 * s-inmaop.ads: Fix spelling mistake in one of the comments.
26616 2004-05-10 Robert Dewar <dewar@gnat.com>
26618 * gnat_ugn.texi: Document that for config pragma files, the maximum
26619 line length is always 32767.
26621 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
26622 literals is now allowed.
26624 * gnat-style.texi: Remove statement about splitting long lines before
26625 an operator rather than after, since we do not follow this rule at all.
26626 Clarify rule (really lack of rule) for spaces around exponentiation
26628 * sem_elim.adb: Allow concatenation of string literals as well as a
26629 single string literal for pragma arguments.
26631 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
26633 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
26634 written for append case.
26636 * frontend.adb: Changes to avoid checking max line length in config
26639 * g-os_lib.ads: Minor reformatting
26641 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
26642 wrong in any case. Instead use standard value. Noticed during code

27713 * sem_prag.adb (Set_Exported): Warn about making static as result of
27714 export only when the export is coming from source. This may be not
27715 be true e.g. on VMS where we expand export pragmas for exception codes
27716 together with imported or exported exceptions, and we don't want the
27717 user to be warned about something he didn't write.
27719 2004-04-08 Thomas Quinot <quinot@act-europe.fr>
27721 * sem_util.adb (Note_Possible_Modification): Reorganize to remove code
27722 duplication between normal entities and those declared as renamings.

27725 * s-fileio.ads (Form): Remove pragma Inline, as we cannot currently
27726 inline functions returning an unconstrained result.

27822 specified radix_digits is greater or equal to machine_mantissa.
27824 2004-04-05 Javier Miranda <miranda@gnat.com>
27826 * par-ch3.adb: Complete documentation of previous change
27827 Correct wrong syntax documentation of the OBJECT_DECLARATION rule

27832 * par-ch6.adb: Complete documentation of previous change.
27834 * sinfo.ads: Fix typo in commment.
27836 2004-04-05 Ed Schonberg <schonberg@gnat.com>
27838 * sem_ch3.adb (Inherit_Components): If derived type is private and has

27840 as is done for non-private derived record types.
27842 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
27843 Ada 2005 AI-310: an abstract non-dispatching operation is not a
27844 candidate interpretation in an overloaded call.

27847 expression is Null and target type is not an access type (e.g. a

27852 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
27853 statement whose right-hand side is an inlined call, save a copy of the
27854 original assignment subtree to preserve enough consistency for
27855 Analyze_Assignment to proceed.
27857 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
27858 complete assignment subtree which is now unnecessary, as the expansion
27859 of inlined call has been improved to preserve a consistent assignment
27860 tree. Note_Possible_Modification must be called only
27861 after checks have been applied, or else unnecessary checks will
27864 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
27865 of explicit dereferences that do not Come_From_Source:
27866 - be selective on cases where we must go back to the dereferenced
27867 pointer (an assignment to an implicit dereference must not be
27868 recorded as modifying the pointer);
27869 - do not rely on Original_Node being present (Analyze_Assignment
27870 calls Note_Possible_Modification on a copied tree).
27872 * sem_warn.adb (Check_References): When an unset reference to a pointer
27873 that is never assigned is encountered, prefer '<pointer> may be null'
27874 warning over '<pointer> is never assigned a value'.

27943 a string literal, create a temporary for it, constant folding only
27944 handles scalars here.
27946 2004-04-01 Vincent Celier <celier@gnat.com>

28130 2004-03-29 Ed Schonberg <schonberg@gnat.com>
28132 * exp_ch6.adb (Expand_Call): A call to a function declared in the
28133 current unit cannot be inlined if it appears in the body of a withed
28134 unit, to avoid order of elaboration problems in gigi.
28136 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
28137 information for protected (wrapper) operation as well, to simplify gdb
28140 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
28141 protected body, indicate that the entity for the generated spec comes

28183 a classwide type (for which Is_Object_Reference holds), but it can
28184 also be a value conversion for an access-to-classwide type. In the
28185 latter case, there is an implicit dereference, and the original node
28186 for the prefix does not verify Is_Object_Reference.

28262 case when the source contains only comments.
28264 2004-03-22 Ed Schonberg <schonberg@gnat.com>
28266 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
28267 declaration for a child subprogram body that acts as a spec, indicate
28268 that the entity in the declaration needs debugging information.
28270 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
28271 full view if the subtype is created for a constrained record component;
28272 gigi has enough information to construct the record, and there is no
28273 place in the tree for the declaration.
28275 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
28276 serial number for the dummy body that is built for analysis, to avoid
28277 inconsistencies in the generation of internal names when compiling
28280 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
28282 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
28285 2004-03-22 GNAT Script <nobody@gnat.com>
28287 * Make-lang.in: Makefile automatically updated
28289 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28291 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.

28316 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
28318 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
28319 as regular exception objects and not as mere integers representing the
28320 condition code. The latter approach required some dynamics to mask off
28321 severity bits, which did not fit well into the GCC table based model.
28322 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
28323 exception data objects. We don't it and it would conflict with the other
28324 external symbol we have to generate for such exceptions.
28326 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
28327 the special code for VMS exceptions, since these are now represented
28328 as regular exceptions objects.
28330 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28332 * decl.c (debug_no_type_hash): Remove.

28336 2004-03-19 Laurent Guerby <laurent@guerby.net>
28338 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
28339 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
28341 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28343 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.

28363 * adaint.c: Update comments.
28365 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
28366 GNATLIB_SHARED for FreeBSD.
28368 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
28370 * init.c [VxWorks]: Do not fix the stack size for the environment task.
28371 When needed (stack checking) the stack size is retrieved
28372 from the VxWorks kernel.
28374 * Makefile.in: Flag -nostdinc is required when building the run time
28375 for avoiding looking for files in the base compiler.
28376 Add the VxWorks specific version of the package body for
28377 System.Stack_checking.Operations (5zstchop.adb).
28379 * Make-lang.in: Add the object file for
28380 System.Stack_Checking.Operations.
28382 * Makefile.rtl: Add object file for the package
28383 System.Stack_Checking.Operations.

28387 * s-stache.ads, s-stache.adb: Move the operations related to stack
28388 checking from this package to package System.Stack_Checking.Operations.
28389 This way, stack checking operations are only linked in the final
28390 executable when using the -fstack-check flag.
28392 2004-03-18 Doug Rupp <rupp@gnat.com>
28394 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

28404 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
28405 the procedures Add_To_Path_File.
28406 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
28407 making sure that each directory is present only once and, for object
28408 dirs, when a directory already present is added, the duplicate is
28409 removed and the directory is always put as the last in the table.
28410 Write the path files at the end of these accumulations.
28412 * prj-nmsc.adb (Record_Source): Add source file name in hash table
28413 Files_Htable for all sources.
28415 * prj-proc.adb (Process): Remove restrictions between not directly
28416 related extending projects.

28424 parameter Trusted_Mode.
28426 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
28428 * scn.adb (Determine_License): Take into account a degenerated case
28429 when the source contains only comments.
28431 2004-03-18 Ed Schonberg <schonberg@gnat.com>
28433 * sem_warn.adb (Check_References): For a warning on a selected
28434 component that does not come from source, locate an uninitialized
28435 component of the record type to produce a more precise error message.
28437 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
28439 * 3zsoccon.ads: Fix multicast options.
28441 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
28444 2004-03-15 Robert Dewar <dewar@gnat.com>
28446 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
28447 pragma used for a private type.
28449 * lib-xref.adb (Generate_Reference): Do not generate warning if
28450 reference is in a different unit from the pragma Unreferenced.
28452 * 5vtpopde.adb: Minor reformatting
28453 Fix casing of To_Task_ID
28455 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
28456 flag if we have an unchecked conversion to an access type in the same
28459 2004-03-15 Geert Bosch <bosch@gnat.com>
28461 * a-ngcoty.adb (Modulus): In alternate formula for large real or
28462 imaginary parts, use Double precision throughout.
28464 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
28465 we want to be able to compile run-time with -gnata for testing, but
28466 this may also be instantiated in user code that is compiled with -gnata.
28468 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
28470 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
28471 codes. Having a separate type for this is useful to enforce consistency
28472 throughout the various run-time units.
28473 (Exception_Data): Use Exception_Code for Import_Code.
28475 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
28476 Natural and Integer in various places.

28478 with the severity bits masked off.
28479 (Register_VMS_Exception): Handle the additional exception data pointer

28483 component, now reflected by an exported accessor.
28484 (is_handled_by): New routine to compute whether the propagated
28485 occurrence matches some handler choice specification. Extracted out of
28486 get_action_description_for, and expanded to take care of the VMS
28488 (get_action_description_for): Use is_handled_by instead of an explicit
28489 complex condition to decide if the current choice at hand catches the
28490 propagated occurrence.
28492 * raise.h (Exception_Code): New type for C.
28494 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
28495 System.Standard_Library.Exception_Code, to allow references from the
28496 pragma import/export expander.
28498 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
28499 New accessors to allow easy access to GNAT exception data
28501 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
28502 redundant Handled_By_Others component, helper for the personality
28503 routine which will now be able to call the appropriate exception data
28506 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
28507 component of Standard_Exception_Type to be the closest possible to
28508 Exception_Code in System.Standard_Library, that we cannot get at this
28509 point. Expand a ??? comment to notify that this type node should
28510 probably be rewritten later on.
28512 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
28513 registration call to include a pointer to the exception object in the
28516 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
28517 instead of int and explicit bitmasks.
28519 2004-03-15 Vincent Celier <celier@gnat.com>
28521 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
28522 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
28524 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
28525 longer needed now that it is in the spec of
28526 System.Tasking.Task_Attributes.
28528 * adaint.h, adaint.c: (__gnat_create_output_file): New function
28530 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
28532 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
28534 * make.adb (Gnatmake): Do not check the executable suffix; it is being
28535 taken care of in Scan_Make_Arg.
28536 (Scan_Make_Arg): Add the executable suffix only if the argument
28537 following -o, in canonical case, does not end with the executable
28538 suffix. When in verbose mode and executable file name does not end
28539 with executable suffix, output the executable name, in canonical case.
28541 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
28542 to avoid warnings when instantiating Ada.Task_Attributes.
28545 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
28546 in the correct order.
28548 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

28553 directory, instead of the Value.
28554 (Find_Source_Dirs): Remove useless code & comments.
28556 2004-03-15 Ed Schonberg <schonberg@gnat.com>
28558 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
28559 tagged type is inherited, and the parent operation is not frozen yet,
28560 force generation of a freeze node for the inherited operation, so the
28561 corresponding dispatch entry is properly initialized.
28562 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
28563 when looking for user-defined equality operation.
28565 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
28566 boolean when locating primitive equality of tagged component.
28568 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

28570 a temporary before expanding assignment into a loop.
28572 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
28573 priority in full, to ensure that any expanded subepxressions of it are
28574 elaborated in the scope of the init_proc.
28576 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
28577 after object declaration, skipping over code that may have been
28578 generated for validity checks.
28580 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
28581 discriminants, ignore the known discriminants of its full view, if
28582 any, to check legality.
28584 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
28585 component if type has unknown discriminants.
28586 (Analyze_Private_Extension_Declaration): Discriminant constraint is
28587 null if type has unknown discriminants.
28589 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
28590 for end label when present.
28592 * s-fileio.adb (Open): When called with a C_Stream, use given name for
28593 temporary file, rather than an empty string.
28595 2004-03-15 Ed Falis <falis@gnat.com>
28597 * s-thread.adb: Removed, no longer used.
28599 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

28619 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
28620 Insert_Dereference_Action when rewriting an implicit dereference into
28621 an explicit one, this will be taken care of during expansion of the
28622 explicit dereference.
28623 (Expand_N_Slice): Same. Always do the rewriting, even for the case
28624 of non-packed slices, since the dereference action generated by
28625 expansion of the explicit dereference is needed in any case.
28626 (Expand_N_Selected_Component): When rewriting an implicit dereference,
28627 analyze and resolve the rewritten explicit dereference so it is seen
28629 (Insert_Dereference_Action): This procedure is now called only for the
28630 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
28631 dereferences that do not come from source (including explicit
28632 dereferences resulting from rewriting implicit ones), but do not
28633 recursively insert a check for the dereference nodes contained within
28635 (Insert_Dereference_Action): Clarify and correct comment.

29852 * Makefile.in: map 86numaux to a-numaux for x86_64
29854 2004-01-12 Ed Schonberg <schonberg@gnat.com>
29856 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
29857 generated to rename a generic actual, go to the actual itself, the
29858 subtype is not a user-visible entity.
29860 * sem_ch7.adb (Uninstall_Declarations): If an entity in the visible
29861 part is a private subtype, reset the visibility of its full view, if
29862 any, to be consistent.
29865 * sem_ch12.adb (Analyze_Formal_Package): Diagnose properly an attempt
29866 to use a generic package G as a formal package for another generic

29898 2004-01-05 Robert Dewar <dewar@gnat.com>
29900 * 1ssecsta.ads: Default_Secondary_Stack is not a constant since it may
29901 be modified by the binder generated main program if the -D switch is
29904 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
29905 imported functions (since now we expect this to be done for imported
29908 * 5vtaprop.adb: Add several ??? for sections requiring more comments
29909 Minor reformatting throughout
29911 * 5zinit.adb: Minor reformatting
29912 Add 2004 to copyright date
29913 Minor changes to avoid -gnatwa warnings
29914 Correct some instances of using OR instead of OR ELSE (noted while
29915 doing reformatting)
29917 * sprint.adb: Minor updates to avoid -gnatwa warnings
29919 * s-secsta.ads, s-secsta.adb:
29920 (SS_Get_Max): New function to obtain high water mark for ss stack
29921 Default_Secondary_Stack is not a constant since it may be modified by
29922 the binder generated main program if the -D switch is used.
29924 * switch-b.adb: New -Dnnn switch for binder
29927 Make -gnatg imply all warnings currently in -gnatwa
29929 * vms_conv.adb: Minor reformatting
29930 Add 2004 to copyright notice

29953 lib-xref.adb, sem_ch5.adb, sem_ch7.adb, sem_ch8.adb:
29954 Minor reformatting and code clean ups.
29955 Minor changes to prevent -gnatwa warnings
29957 * ali.adb: Minor reformatting and cleanup of code
29958 Acquire new SS indication of secondary stack use from ali files
29960 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
29961 (since now we expect this to be done for imported functions)
29963 * bindgen.adb: Generate call to modify default secondary stack size if
29966 * bindusg.adb: Add line for new -D switch
29968 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
29969 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
29970 Add circuitry for both records and arrays to avoid gigi
29971 processing if the type involved has non-bit-aligned components
29973 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
29974 N_String_Literal node always references an E_String_Literal_Subtype
29975 entity. This may not be true in the future.
29976 (Possible_Bit_Aligned_Component): Move processing of
29977 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
29979 * exp_ch6.adb (Expand_Thread_Body): Pick up
29980 Default_Secondary_Stack_Size as variable so that we get value modified
29981 by possible -Dnnn binder parameter.
29983 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
29984 (Type_May_Have_Bit_Aligned_Components): New function.
29986 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

29994 importing constant atomic/volatile objects.
29995 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
29996 unless explicit Pure_Function pragma given, to avoid insidious bug of
29997 call to non-pure imported function getting eliminated.

30019 * rtsfind.adb (Load_Fail): Give full error message in configurable
30020 run-time mode if all_errors mode is set. This was not done in the case
30021 of a file not found, which was an oversight.
30022 Note if secondary stack unit is used by compiler.
30024 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
30025 ineffective elaborate all pragmas on non-visible packages (this
30026 happened when a renamed subprogram was called). Now the elaborate all
30027 always goes on the package containing the renaming rather than the one
30028 containing the renamed subprogram.
30030 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
30031 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
30033 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
30034 has an Etype that references an E_String_Literal.
30035 (Eval_String_Literal): Avoid assumption that N_String_Literal node
30036 always references an E_String_Literal_Subtype entity. This may not
30037 be true in the future.
30039 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
30042 * sem_res.adb (Resolve): Specialize msg for function name used in proc
30045 2004-01-05 Ed Falis <falis@gnat.com>
30047 * g-debuti.adb: Replaced direct boolean operator with short-circuit
30050 2004-01-05 Vincent Celier <celier@gnat.com>
30052 * bld.adb: Minor comment updates
30053 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
30056 * make.adb (Gnatmake): Special process for files to compile/check when
30057 -B is specified. Fail when there are only foreign mains in attribute
30058 Main of the project file and -B is not specified. Do not skip bind/link
30059 steps when -B is specified.
30061 * makeusg.adb: Document new switch -B
30063 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
30065 * switch-m.adb: (Scan_Make_Switches): Process -B switch
30067 * vms_data.ads: Add new GNAT PRETTY qualifier

30072 * trans.c (tree_transform, case N_Free_Statement): Handle thin pointer
30075 * misc.c (gnat_printable_name): If VERBOSITY is 2, call
30076 Set_Identifier_Casing.
30078 * decl.c (gnat_to_gnu_entity, E_Function): Give error if return type
30079 has size that overflows.
30081 2004-01-05 Gary Dismukes <dismukes@gnat.com>
30083 * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
30084 -gnatwa warning on static condition.
30086 2004-01-05 Doug Rupp <rupp@gnat.com>
30088 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
30090 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
30092 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
30093 all attributes, including read-only attribute.
30095 2004-01-05 Pascal Obry <obry@gnat.com>

30098 library naming scheme.
30100 * mlib-prj.adb (Build_Library): Generate different names for the static
30101 or dynamic version of the GNAT runtime. This is needed to support the
30102 new shared library naming scheme.
30103 (Process_Binder_File): Add detection of shared library in binder file
30104 based on the new naming scheme.
30106 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
30107 scheme for the shared runtime libraries.
30110 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
30112 (install-gnatlib): Do not create symlinks for shared libraries.
30113 (gnatlib-shared-default): Idem.
30114 (gnatlib-shared-dual-win32): New target. Not used for now as the
30115 auto-import feature does not support arrays/records.
30116 (gnatlib-shared-win32): Do not create copy for the shared libraries.
30117 (gnatlib-shared-vms): Fix shared runtime libraries names.
30119 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
30120 dependent runtime shared library name.
30122 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
30124 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
30127 2004-01-05 Ed Schonberg <schonberg@gnat.com>
30129 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
30130 protected objects when allocator has a subtype indication, not a
30131 qualified expression. Note that qualified expressions may have to be
30132 checked when limited aggregates are implemented.
30134 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
30135 pure, emit warning.
30136 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
30137 subprogram is imported, remove warning.
30139 2004-01-05 Geert Bosch <bosch@gnat.com>
30141 * s-poosiz.adb: Update copyright notice.
30142 (Allocate): Use Task_Lock to protect against concurrent access.
30143 (Deallocate): Likewise.
30145 2004-01-05 Joel Brobecker <brobecker@gnat.com>
30147 * s-stalib.adb (Elab_Final_Code): Add missing year in date inside ???

30165 * stamp-xgnatug: New stamp file.
30166 * Make-lang.in (stamp-xgnatug): New stamp file and comment.

30168 (ada/gnat_ug_unx.texi, ada/gnat_ug_vwx.texi, ada/gnat_ug_vms.texi
30169 ada/gnat_ug_wnt.texi): Update to depend on stamp-xgnatug.
30171 2003-12-17 Ed Falis <falis@gnat.com>
30173 * a-elchha.adb (Tailored_Exception_Information): made Info constant to

30177 Ada.Exceptions.Last_Chance_Handler.
30179 2003-12-17 Sergey Rybin <rybin@act-europe.fr>
30181 * cstand.adb (Create_Standard): Change the way how the declaration of
30182 the Duration type is created (making it the same way as it is for all
30183 the other standard types).
30185 2003-12-17 Robert Dewar <dewar@gnat.com>
30187 * s-crtl.ads: Fix header format
30188 Change Pure to Preelaborate
30190 2003-12-17 Ed Schonberg <schonberg@gnat.com>
30192 * checks.adb (Selected_Length_Checks): Generate an Itype reference for
30193 the expression type only if it is declared in the current unit.
30195 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
30196 are universal and already analyzed, as can occur in constrained
30197 subcomponents that depend on discriminants, when one constraint is a
30200 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
30201 type Any_Fixed is legal as the argument of a conversion, if only one
30202 fixed-point type is in context.
30204 2003-12-17 GNAT Script <nobody@gnat.com>

30213 2003-12-15 Vincent Celier <celier@gnat.com>
30215 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
30216 (Gnatchop): Do not set failure status when reporting the number of
30219 2003-12-15 Doug Rupp <rupp@gnat.com>
30221 * s-ctrl.ads: New file.
30223 * Makefile.rtl (GNAT_RTL_NONTASKING_OBJS): Add s-crtl$(objext).
30225 * Make-lang.in: (GNAT_ADA_OBJS): Add ada/s-crtl.o.
30226 (GNATBIND_OBJS): Add ada/s-crtl.o.
30228 * Makefile.in [VMS]: Clean up ifeq rules.
30230 * gnatlink.adb, 6vcstrea.adb, a-direio.adb, a-sequio.adb,

30239 2003-12-15 GNAT Script <nobody@gnat.com>
30241 * Make-lang.in: Makefile automatically updated
30243 2003-12-11 Ed Falis <falis@gnat.com>
30245 * 5zinit.adb: Clean up.
30247 * 5zintman.adb (Notify_Exception): replaced case statement with a call
30248 to __gnat_map_signal, imported from init.c to support
30249 signal -> exception mappings that depend on the vxWorks version.
30252 Created and exported __gnat_map_signal to support signal -> exception
30253 mapping that is dependent on the VxWorks version.

30263 __gnat_handler_installed, as done on all other platforms.
30264 Remove duplicated code.
30266 2003-12-11 Jerome Guitton <guitton@act-europe.fr>
30268 * Makefile.in (rts-zfp, rts-ravenscar): Create libgnat.a.
30270 2003-12-11 Thomas Quinot <quinot@act-europe.fr>
30272 * sinfo.ads: Fix inconsistent example code in comment.
30274 2003-12-11 Robert Dewar <dewar@gnat.com>
30276 * a-tiinau.adb: Add a couple of comments
30278 * sem_ch3.adb: Minor reformatting
30281 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
30282 Minor reformatting throughout
30284 2003-12-11 Ed Schonberg <schonberg@gnat.com>
30286 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
30287 bounds of a loop, create a separate block in order to generate proper
30288 cleanup actions to prevent memory leaks.
30290 * sem_res.adb (Resolve_Call): After a call to
30291 Establish_Transient_Scope, the call may be rewritten and relocated, in
30292 which case no further processing is needed.
30294 * sem_util.adb: (Wrong_Type): Refine previous fix.
30295 Fixes ACATS regressions.
30298 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
30301 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
30303 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
30304 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
30307 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
30310 2003-12-08 Robert Dewar <dewar@gnat.com>
30312 * 7sintman.adb: Minor reformatting
30314 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
30315 standard linker options to get standard libraries linked. We now plan
30316 to provide dummy versions of these libraries to match the appropriate
30317 configurable run-time (e.g. if a library is not needed at all, provide
30318 a dummy empty library).
30320 * targparm.ads: Configurable_Run_Time mode no longer affects linker
30321 options (-L parameters and standard libraries). What we plan to do is
30322 to provide dummy libraries where the libraries are not required.
30324 * gnatbind.adb: Minor comment improvement
30326 2003-12-08 Javier Miranda <miranda@gnat.com>
30328 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
30329 aggregate in the parent. Otherwise constants with limited aggregates
30330 are not supported. Add new formal to pass the component type (Ctype).
30331 It is required to call the corresponding IP subprogram in case of
30332 default initialized components.
30333 (Gen_Assign): In case of default-initialized component, generate a
30334 call to the IP subprogram associated with the component.
30335 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
30336 of aggregate with default initialized components.
30337 (Has_Default_Init_Comps): Improve implementation to recursively check
30338 all the present expressions.
30340 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
30341 to indicate that the initialization call corresponds to a
30342 default-initialized component of an aggregate.
30343 In case of default initialized aggregate with tasks this parameter is
30344 used to generate a null string (this is just a workaround that must be
30345 improved later). In case of discriminants, this parameter is used to
30346 generate a selected component node that gives access to the discriminant
30349 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
30350 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
30351 allocated aggregates with default-initialized components.
30353 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
30354 the box notation is used in positional aggregates.

32094 2003-10-22 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
32096 * tracebak.c (MAX): Avoid redefinition warning.
32098 * init.c [sgi] (__gnat_error_handler): Remove i, unused.
32099 Change msg to const char *.
32100 (__gnat_install_handler): Remove ss, unused.
32101 [sun && __SVR4 && !__vxworks] (__gnat_error_handler): Change msg
32103 * cstreams.c (__gnat_full_name): Declare p only when used.
32104 (__gnat_full_name) [sgi] Return buffer.
32106 2003-10-22 Arnaud Charlet <charlet@act-europe.fr>
32108 * mingw32.h: New file.
32109 * gnat_wrapper.adb: New file.
32111 2003-10-22 Jerome Roussel <roussel@act-europe.fr>
32113 * g-regpat.ads, g-regpat.adb (Match): new function, to know if a
32114 string match a pre compiled regular expression (the corresponding
32115 version of the function working on a raw regular expression)
32116 Fix typos in various comments
32117 Update copyright notice in spec
32119 2003-10-21 Gary Dismukes <dismukes@gnat.com>
32122 (Component_Needs_Simple_Initialization): Return False when the type is a
32123 packed bit array. Revise spec comments to document this case.
32126 (Expand_Pragma_Import): Set any expression on the imported object to
32127 empty to avoid initializing imported objects (in particular this
32128 covers the case of zero-initialization of bit arrays).
32129 Update copyright notice.
32131 2003-10-21 Ed Schonberg <schonberg@gnat.com>
32134 (Load_Parent_Of_Generic): If parent is compilation unit, stop search,
32135 a subunit is missing.
32136 (Instantiate_Subprogram_Body): If body of function is missing, set type
32137 of return expression explicitly in dummy body, to prevent cascaded
32138 errors when a subunit is missing.
32142 (Access_Subprogram_Declaration): Verify that return type is valid.
32146 (Check_Elab_Calls): Do not apply elaboration checks if the main unit is
32151 (Corresponding_Discriminant): If the scope of the discriminant is a
32152 private type without discriminant, use its full view.

34159 (general) Add @./@: where approriate, and two spaces after the
34160 full stop at the end of a sentence. Use @samp markup when
34161 referring concrete lexical entities (keywords, attribute names
34162 etc.), and @syntax for ARM grammar elements. Use @r for English

34177 * make.adb (Add_Switch): Make Generic_Position a procedure. The
34178 function approach did not work well because of a side effect (the
34179 function call could reallocate the table which was being indexed
34180 using its result). Fixes ada/4851.

34239 Add 2001 to copyright date
34241 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
34242 need to force universal inlining for these cases.

34273 the argument of an initialization procedure.
34275 * trans.c (tree_transform, case of arithmetic operators): If result
34276 type is private, the gnu_type is the base type of the full view,

34366 Above changes fix problem with length computation for supernull arrays
34367 where Max (Len, 0) wasn't getting applied due to the Unsigned
34368 conversion used by Compute_Length.

34458 When using a project file, fail if specified executable is relative
34459 path with directory information, and prepend executable, if not
34460 specified as an absolute path, with the exec directory. Make sure
34461 that only one -o switch is transmitted to the linker.
34463 * prj-attr.adb (Initialization_Data): Add project attribute Exec_Dir

34544 there could be a real problem here with an uninitialized reference
34545 to Hbound, but no actual example of failure has been found.
34547 2001-12-17 Laurent Pautet <pautet@gnat.com>
34550 Fix comment of Shutdown_Socket and Close_Socket. These functions
34551 should not fail silently because if they are called twice, this
34552 probably means that there is a race condition in the user program.
34553 Anyway, this behaviour is consistent with the rest of this unit.
34554 When an error occurs, an exception is raised with the error message
34555 as exception message.
34557 2001-12-17 Robert Dewar <dewar@gnat.com>

35889 instead of the previous simple checksum algorithm.
35890 (Time_Stamp_Mismatch): use CRC_Match for comparison.
35891 (Set_Source_Table): idem.
35894 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
35895 instead of simple checksum.
35896 (CRC_Match): new function.
35897 (CRC_Error): new constant.
35899 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
35900 a CRC now and not a simple checksum. A CRC uses lower-case hex
35901 letters, fixes ambiguity in parsing.
35903 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
35904 is what this variable will store.
35906 * bcheck.adb: Change reference to chechsum in comments by CRC.
35907 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
35908 rename All_Checksum_Match to All_CRC_Match. Change due to API
35909 renaming since now GNAT does not use a simple checksum but a
35910 CRC using GNAT.CRC32.
35912 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
35913 now and not anymore a simple checksum.
35915 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many

35950 Update comments for the CRC.
35952 * types.adb (Hex): Use lowercase for the letter part.
35954 * types.ads (Get_Hex_String): Returns the hexadecimal representation
35955 for a word. This is currently used only for CRC. In previous version,
35956 the checksum was using a representation with all letter being
35957 upper-case. With the new implementation (using CRC) we do not remove
35958 the 32th bit of the CRC, so we can have an upper-case starting letter
35959 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
35960 It is ambigous since the CRC was optional and could be followed by
35961 options like EB, EE. So now this routines uses lower-case letter for
35962 the hexadecimal representation. Strange enough only lower case letters
35963 where checked in Scan_ALI (even if this was not a possible case).
35965 * gnatvsn.ads (Library_Version): changed to 3.15a.
35967 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
35970 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version

35974 Add 2001 to copyright notice
35975 (Accumulate_Checksum): Modify to use System.CRC32.
35977 * ali-util.ads: Redo changes of previous revision to continue to use
35978 the word Checksum. Add 2001 to copyright notice.
