3845 clauses for inherited components of a type extension.
3846 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for

3979 subprogram body that acts as its own spec may not have a non-private
3980 WITH clause on a private sibling.
3981 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
3982 child unit is a renaming, create an implicit with_clause on that
3983 parent, and not on the unit it renames, to prevent visibility errors

4085 perform subtype conformance between the formals of the current entry
4086 and those of the target interface primitive.
4087 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
4088 Timed_Entry_Call): Analyze the triggering statement as the first step of
4089 the processing. If this is a dispatching select, postpone the analysis
4090 of all select statements until the Expander transforms the select. This

4092 replicated some of the select statements. In case the Expander is
4093 disabled, perform regular analysis.
4094 (Check_Triggering_Statement): New routine.
4095 (Analyze_Requeue): Exclude any interpretations that are not entries when
4096 checking overloaded names in a requeue. Also test type conformance for

4710 additional management on these nodes in Expand_Interface_Actuals.
4712 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
4713 that handles use of 'Access and 'Unchecked_Access applied to

4806 association for an access component, add an association with null as
4807 the expression. Remove testing for array subtypes and the setting in

4809 inclusion of an association for null-initialized arrays. Collapse
4810 condition that tests for array subtypes into just a test of
4811 Is_Partially_Initialized_Type (which already covers arrays anyway).

4828 * sem_ch4.adb: Minor code and comment reformatting.
4829 (Analyze_Allocator): When the designated type of an unconstrained

4959 files instead of units to gigi.
4960 * gigi.h (struct File_Info_Type): New.
4961 (gigi): Rename and change type of number_units parameter, change
4962 type of file_info_ptr parameter.
4963 * trans.c (number_files): New global variable.
4964 (gigi): Rename and change type of number_units parameter, change
4965 type of file_info_ptr parameter.
4966 If mapped location support is enabled, create the isomorphic mapping
4967 between source files and line maps.
4968 (Sloc_to_locus): If mapped location support is enabled, translate
4969 source location into mapped location.
4970 (annotate_with_node): Rename into set_expr_location_from_node.

4996 * a-calend-vms.adb, a-calend.adb:
4997 Add a section on leap seconds control along with two entities used to
4998 enable and disable leap seconds support. The array Leap_Second_Times is
4999 now constant and contains hard time values pre-generated. Remove
5000 all elaboration code used to populate the table of leap seconds.
5003 Add entity Leap_Seconds_Support to the list of global run-time variables
5004 along with a comment on its usage and values.

5019 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
5020 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
5022 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
5024 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
5025 function which can be called by the debugger to interrupt the tasks of
5026 an Ada application asynchronously, as needed on VxWorks.
5027 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
5029 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,

5060 2007-09-26 Javier Miranda <miranda@adacore.com>
5061 Eric Botcazou <ebotcazou@adacore.com>
5064 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
5065 indirection added to the HT_Link component of the TSD. This is required
5066 to statically allocate the TSD.
5069 Minor reordering of the declarations in the private part. Required to
5070 add a level of indirection to the contents of the TSD component HT_Link.
5071 This is required to statically allocate the TSD.
5073 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
5074 Is_Statically_Allocated set from constant objects.
5075 Do not make exported constants created by the compiler volatile.
5076 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
5079 * trans.c (Identifier_to_gnu): For constants, unshare initializers
5080 before returning them.
5082 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
5083 public part of the package.
5084 (Make_DT): Move HT_Link component out of the TSD record. For this
5085 purpose Make_DT now declares a separate object that stores the
5086 HT_Link value, and initializes the TSD component with the address
5087 of this new object. The addition of this level of indirection is
5088 required to statically allocate the TSD because the TSD cannot
5089 have variable components.
5090 (Expand_Interface_Conversion): Improve the expanded code.
5091 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
5093 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
5094 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
5095 if we are building static dispatch tables then we must not generate
5096 extra code to register the primitive because the dispatch table will
5097 be built at the end of the library package; otherwise we notify that
5098 we cannot build the static dispatch table.
5100 2007-09-26 Robert Dewar <dewar@adacore.com>
5102 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

5117 for thunks associated with interface types.
5119 * einfo.ads: Improve documentatation of Is_Internal
5120 (Is_Thunk): New attribute applicable to subprograms. True for thunks
5121 associated with interface types.
5122 Extensive comment fixes regarding flags that appear in all entities. The
5123 documentation is now consistent for all such flags (there were a number
5124 of errors in the documentation in this regard).
5126 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
5128 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
5129 of these procedures are passed a function call that already has
5130 build-in-place actuals (testing new flag
5131 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
5132 the case where processing continues.
5133 (Expand_Call): If the call is generated from a thunk body then we
5134 propagate the extra actuals associated with the accessibility
5135 level of the access type actuals.
5137 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
5138 of each extra formal of a protected operation to reference the
5139 corresponding extra formal of the subprogram denoted by the
5140 operation's Protected_Body_Subprogram.
5142 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
5143 N_Function_Call nodes.
5145 2007-09-26 Robert Dewar <dewar@adacore.com>
5147 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
5149 * debug.adb: Add d.s flag.

5153 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
5154 debug variable so that it won't be initialized when pragma
5155 Initialize_Scalars is in effect.
5157 2007-09-26 Gary Dismukes <dismukes@adacore.com>
5159 * freeze.adb (Freeze_Entity): Remove check for preelaborable
5160 initialization of a full view. This is moved to
5161 Analyze_Package_Specification.
5163 * sem_ch7.adb (Analyze_Package_Specification): Add check for
5164 preelaborable initialization of a full view in entity loop.
5165 (Uninstall_Declarations): If entity is a use-visible compilation unit,
5166 its child units are use-visible only if they are visible child units.
5168 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
5169 whether an expression can be used within a type declaration that
5170 requires preelaborable init.
5171 (Check_Components): Replace inline code that does partial checking for
5172 preelaborable default expressions with call to
5173 Is_Preelaborable_Expression.
5174 (Has_Preelaborable_Initialization): In the case of a generic actual
5175 subtype, (that is, Is_Generic_Actual is True), return the result of
5176 applying Has_Preelaborable_Initialization to the generic actual's base
5179 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
5181 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
5182 call to Jan_1_Day _Of_Week to optimize its performance.
5183 (Is_Leap): Move the routine to the scope of Week_In_Year.
5184 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
5185 weekday on which January 1 falls of Year - 1 and Year + 1. This function
5186 avoids calling Time_Of and Split, thus making it more efficent.
5187 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
5189 * g-calend.ads (Week_In_Year): Change comment to reflect new
5192 2007-09-26 Emmanuel Briot <briot@adacore.com>

5195 Command_Line): New types
5196 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
5197 support for defining how switches can be grouped on a command line (as
5198 is the case for -gnatw... for GNAT), and how simple switches can be
5199 used as aliases for more complex switches (-gnatwa is same as
5201 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
5202 (Start, Current_*): New subprograms
5203 Added support for parsing an array of strings in addition to the real
5205 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
5206 be moved from the body to the private part of the spec.
5207 (*): All subprograms now have an extra parameter with default value to
5208 specify which parser should be used. For backward compatibility, it
5209 defaults to parsing the command line of the application. They were also
5210 modified to properly handle cases where each of the argument does not
5211 start at index 1 (which is always true for Ada.Command_Line, but not
5212 when processing any Argument_List).
5213 (Free): New subprogram
5214 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
5215 Argument): New subprograms
5216 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
5217 special characters like ':', '=',... are now handled in a single place,
5218 which makes the code more extensible eventually.
5219 (Getopt, Full_Switch): When the switch was returned as part of the
5220 special character '*', make sure it is prepended by the switch character
5221 ('-' in general), so that the application knows whether "foo" or "-foo"
5222 was specified on the command line.
5224 2007-09-26 Florian Villoing <villoing@adacore.com>
5226 * g-dirope.adb (Remove_Dir): In case we are removing directories
5227 recursively, make sure that if an exception is raised during the
5228 processing, the current working directory is reset to its initial
5229 value before propagating the exception.
5231 2007-09-26 Vincent Celier <celier@adacore.com>
5233 * gnatbind.adb: If there are several ALI files specified and there is
5234 a main program to bind, the first ALI is expected to contain the main
5235 subprogram and the names of the binder generated files will be derived
5236 from the first ALI file name.
5237 (Gnatbind): Fix insertion character in invocation of Error_Msg
5239 2007-09-26 Vincent Celier <celier@adacore.com>
5241 * gnatcmd.adb (Check_Files): Do not include sources that have been
5242 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
5244 2007-09-26 Ed Schonberg <schonberg@adacore.com>
5246 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
5247 information about each of its index types, following the type
5248 reference for its component type.
5250 2007-09-26 Vincent Celier <celier@adacore.com>
5252 * make.adb: (Kill): New procedure (__gnat_kill imported)

5254 were previously local to procedure Compile_Sources.
5255 (Sigint_Intercepted): Send signal SIGINT to all outstanding
5256 compilation processes.

5259 sources, so that the correct paths will be found.
5261 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
5263 2007-09-26 Vincent Celier <celier@adacore.com>
5265 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
5267 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
5268 Replace components Compiler_Min_Options and Binder_Min_Options with
5269 Compiler_Required_Switches and Binder_Required_Switches in record
5271 Remove components Default_Language and Config in Project_Tree_Data,
5274 * prj-attr.adb: New attributes Required_Switches (<language>) in
5275 packages Compiler and Binder.
5277 * prj-nmsc.adb: Major rewrite of the processing of configuration
5278 attributes for gprbuild. No impact on GNAT tools.
5280 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
5281 process configuration attributes: this is done in Prj.Nmsc.Check.

5286 (Process): Implementation now uses the two new procedures
5288 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
5289 from the project config, not the tree config that no longer exists.
5291 2007-09-26 Vincent Celier <celier@adacore.com>

5315 ancestor of the derived type, the operations are inherited from the
5316 primary dispatch table of the parent.
5317 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
5318 when the context is an explicit type conversion.

5620 potentially be called.
5621 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
5622 body for 'Output when the type is abstract (only the creation of the
5623 body for 'Input is excluded when the type is abstract).
5624 (Stream_Operation_OK): Add an additional condition in the return
5625 statement, so that False will be returned for TTS_Stream_Input if the
5626 associated tagged type is an abstract extension. Add comments for
5628 (Expand_N_Object_Declaration): For the case of a shared passive
5629 variable, insert init proc call only after the shared variable
5630 procedures have been processed, because the IP call needs to undergo
5631 shared passive variable reference expansion, which requires these
5632 procedures to be available (and elaborated).

5643 and the value of the discriminant is the discriminant of the enclosing
5644 type, retrieve its value from the aggregate itself, where it must have
5647 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
5648 to remove other spurious ambiguities on arithmetic operations involving
5649 literals and addresses, on systems where Address is a visible integer
5650 type, when the operator is called in functional notation.
5651 (Try_Primitive_Operation): Within an instance, a call in prefixed form
5652 is legal when the types match, even if the operation is currently

5657 * sem_ch12.adb (Build_Local_Package): A formal package with no
5658 associations is legal if all formals have defaults. It is not

5845 (Write_String_Table_Entry): If the string to be printed is very long,
5846 just print the first few characters, followed by the length. Otherwise,
5847 doing "pn(n)" in the debugger can take an extremely long time.
5849 * sem_prag.adb (Process_Interface_Name): Replace loop doing
5850 Store_String_Char with Store_String_Chars.
5852 2007-08-31 Vincent Celier <celier@adacore.com>
5854 * prj-attr.adb: Add new attribute Excluded_Source_Files

5864 clauses of subunits, ignore limited_with_clauses that are illegal and
5865 have not been fully analyzed.
5867 2007-08-31 Ed Schonberg <schonberg@adacore.com>
5869 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
5870 flag, for effiency. It is called when analyzing arithmetic operators
5871 and also for actuals in calls that are universal_integers. The flag is
5872 set for the predefined type address, and for any type or subtype
5875 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
5876 Universal_Integer, when the formal is a descendent of address and the
5877 call appears in user code.
5878 (Analyze_Selected_Component): if the prefix is a private extension, the
5879 tag component is visible.
5881 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
5884 2007-08-31 Robert Dewar <dewar@adacore.com>
5886 * s-fileio.adb (Open): Normalize file name to lower case in non-case
5887 sensitive file name systems to avoid unexpected mismatch in Vista.

5915 Documentation cleanup only.
5917 2007-08-31 Sergey Rybin <rybin@adacore.com>
5919 * vms_data.ads: Add new qualifier /STMT_NAME_ON_NEW_LINE for the new
5920 gnatpp '--separate-stmt-name' option.

5924 * gnat_ugn.texi: Add description for the new gnatpp
5925 '--separate-stmt-name' and '--use-on-new-line' options.

5938 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
5940 * misc.c (gnat_type_max_size): Constify.
5942 2007-08-16 Gary Dismukes <dismukes@adacore.com>
5944 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
5945 associated with Standard_Debug_Renaming_Type, to be used as the type of
5946 the special variables whose names provide debugger encodings for
5947 renaming declarations.
5949 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
5950 (Set_Debug_Renaming_Link): Change to set Node25.
5951 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
5952 (Write_Field25_Name): Add case for E_Variable to output
5953 "Debug_Renaming_Link".
5954 (Write_Field23_Name): Correct the output string for "Limited_View".
5956 * exp_dbug.adb: Add with and use of Tbuild.
5957 (Debug_Renaming_Declaration): Replace creation of an enumeration type
5958 and literal with creation of a variable of type
5959 Standard_Debug_Renaming_Type whose name encodes both the renamed object
5960 and the entity of the renaming declaration.
5961 (Qualify_Entity_Name): Add the delayed qualification of the entity name
5962 part of the name of a variable that has a Debug_Renaming_Link.
5964 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
5965 special type to be associated with variables that provide debugger
5966 encodings for renaming declarations.

5969 Ed Schonberg <schonberg@adacore.com>
5970 Javier Miranda <miranda@adacore.com>
5972 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
5973 ancestor part given by an aggregate to test for an unchecked conversion,
5974 since this can occur in some cases when the ancestor part is a function
5975 call, and we don't want to fall into the recursive call to this
5976 procedure in that case.
5978 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
5979 stream attributes on limited types to account for user-specified
5980 attributes as well as whether Input (resp. Output) becomes available
5981 due to Read (resp. Write) being available for the type. Change Boolean
5982 variable to the more accurate name
5983 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
5984 double-"not" predicate at beginning of return statement to more
5985 understandable form.
5987 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
5988 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
5989 in a block statement and use that as the first statement of the
5990 expanded return rather than incorrectly using the handled sequence as
5991 the first statement.
5993 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
5994 operation, generate an explicit freeze node for it rather than
5995 generating extra formals, to ensure that gigi has the proper order of
5996 elaboration for anonymous subtypes in the signature of the subprograms.
5997 (Build_In_Place_Formal): Move assertion to beginning of loop.
5998 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
5999 applied to a function call (occurs for some cases of 'Input).
6000 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
6001 applied to a function call (occurs for some cases of 'Input).
6003 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
6004 2005, generate an extended return statement enclosing the result object
6007 * freeze.adb (Freeze_Record_Type): Extend the current management of
6008 components that are access type with an allocator as default value: add
6009 missing support to the use of qualified expressions of the
6010 allocator (which also cause freezing of the designated type!)
6011 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
6012 dispatching operation, since extra formals may be needed by calls to
6013 build-in-place functions (such as stream 'Input).
6015 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
6016 formals for 'Constrained and accessibility level in the case of a
6017 predefined dispatching operation.
6019 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
6020 point, no need to find the parent node.
6022 2007-08-16 Javier Miranda <miranda@adacore.com>
6024 * exp_attr.adb (Attribute_Priority): Add missing support for entries
6027 2007-08-16 Javier Miranda <miranda@adacore.com>
6029 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
6030 is not really required and can introduce regression with the debugger.
6031 The original problem is fixed with the patch written for checks.adb.
6033 2007-08-16 Thomas Quinot <quinot@adacore.com>
6035 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
6036 Range_Check on Allocated_Table.

6040 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
6041 Including_Non_Switch set to False.
6042 (Gnatmake): For the compiler, call Test_If_Relative_Path with
6043 Including_Non_Switch set to False.
6045 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
6046 parameter Including_Non_Switch, defaulted to True. When
6047 Including_Non_Switch is False, options that are not switches and
6048 appear as relative path are not converted to absolute paths.
6050 2007-08-16 Nicolas Roche <roche@adacore.com>
6052 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
6055 * Make-lang.in: Update dependencies

6060 currently inspected is a selected component, retrieve the entity of
6062 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
6063 from the immediate ancestor of Main_Unit_Entity.
6064 (Install_Limited_Withed_Unit): Do not install the limited view of
6065 package P if P is reachable through an ancestor chain from package C
6066 and C also has a with clause for P in its body.
6067 (Has_Limited_With_Clause): New routine.
6068 (Has_With_Clause): New routine.
6070 2007-08-16 Ed Schonberg <schonberg@adacore.com>
6072 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
6073 generic for an enclosing instance is a global reference, even though
6074 its scope is the enclosing instance.
6076 2007-08-16 Gary Dismukes <dismukes@adacore.com>
6077 Javier Miranda <miranda@adacore.com>
6079 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
6080 initialize a limited object.
6081 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
6083 Make sure Has_Complex_Representation is inherited by derived type.

6087 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
6090 2007-08-16 Ed Schonberg <schonberg@adacore.com>
6092 * sem_disp.adb (Check_Dispatching_Operation): If the operation
6093 implements an operation inherited from a progenitor interface, verify
6094 that they are subtype-conformant.
6096 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
6097 Bob Duff <duff@adacore.com>
6098 Nicolas Setton <setton@adacore.com>
6100 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
6101 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
6102 the statement which is being resolved comes from a predefined library
6103 unit, all non-predefined library interpretations are skipped.
6104 (Resolve_Op_Concat): If string concatenation was folded in the parser,
6105 but the "&" is user defined, give an error, because the folding would
6108 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
6109 the parser has folded a long sequence of concatenations of string
6112 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
6113 and "JMP_BUF" variables as artificial.
6114 (N_String_Literal): Do not use alloca for very long string literals. Use
6115 xmalloc/free instead. Otherwise the stack might overflow.
6117 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
6120 2007-08-16 Vincent Celier <celier@adacore.com>
6122 * vms_conv.adb (Process_Argument): Ensure that project related options
6123 are not put in the -cargs section when using GNAT COMPILE.
6125 2007-08-16 Robert Dewar <dewar@adacore.com>
6127 * gnat_ugn.texi: Add note on preprocessing (output file not written)
6129 2007-08-16 Thomas Quinot <quinot@adacore.com>

6153 s-osinte-solaris.adb, s-osinte-solaris.ads,
6154 s-osinte-freebsd.ads, s-osinte-freebsd.adb: Minor reformatting.

6157 switch -gnatyS. Enable -gnatyS in GNAT style check mode
6159 2007-08-14 Robert Dewar <dewar@adacore.com>
6160 Ed Schonberg <schonberg@adacore.com>
6162 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
6163 Suppress unmodified in-out parameter warning in some cases
6164 This patch is a also fairly significant change to the way suppressible
6167 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
6168 needed for access to concurrent record types generated by the expander.
6169 (Generate_Range_Check): When generating a temporary to capture the
6170 value of a conversion that requires a range check, set the type of the
6171 temporary before rewriting the node, so that the type is always
6172 properly placed for back-end use.
6173 (Apply_Float_Conversion_Check): Handle case where the conversion is
6175 (Get_Discriminal): Code reformatting. Climb the scope stack looking
6176 for a protected type in order to examine its discriminants.
6178 2007-08-14 Robert Dewar <dewar@adacore.com>
6179 Gary Dismukes <dismukes@adacore.com>
6180 Ed Schonberg <schonberg@adacore.com>
6181 Thomas Quinot <quinot@adacore.com>
6183 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
6184 a-stwisu.adb, a-strsup.adb: Fix warnings for range
6185 tests optimized out.
6187 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
6188 (Get_Allocator_Final_List): For the case of an anonymous access type
6189 that has a specified Associated_Final_Chain, do not go up to the
6191 (Expand_N_Type_Conversion): Test for the case of renamings of access
6192 parameters when deciding whether to apply a run-time accessibility
6194 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
6195 aggregate code before allocator, and ahead of declaration for
6196 temporary, to prevent access before elaboration when the allocator is
6197 an actual for an access parameter.
6198 (Expand_N_Type_Conversion): On an access type conversion involving an
6199 access parameter, do not apply an accessibility check when the
6200 operand's original node was an attribute other than 'Access. We now
6201 create access conversions for the expansion of 'Unchecked_Access and
6202 'Unrestricted_Access in certain cases and clearly accessibility should
6203 not be checked for those.
6205 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
6206 includes a type conversion of a packed component that has been expanded,
6207 recover the original expression for the object, and use this expression
6208 in the post-call assignment statement, so that the assignment is made
6209 to the object and not to a back-end temporary.
6210 (Freeze_Subprogram): In case of primitives of tagged types not defined
6211 at the library level force generation of code to register the primitive
6212 in the dispatch table. In addition some code reorganization has been
6213 done to leave the implementation clear.
6214 (Expand_Call): When expanding an inherited implicit conversion,
6215 preserve the type of the inherited function after the intrinsic
6216 operation has been expanded.
6218 * exp_ch2.ads, exp_ch2.adb
6219 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
6220 of an entry formal appearing in an assignment statement does not assign
6222 (Expand_Current_Value): Instead of calling a routine to determine
6223 whether the prefix of an attribute reference should be optimized or
6224 not, prevent the optimization of such prefixes all together.
6226 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
6227 component whose prefix is known to be of an access type is an implicit
6228 dereference and does not assign to the prefix.
6230 2007-08-14 Ed Schonberg <schonberg@adacore.com>
6231 Robert Dewar <dewar@adacore.com>
6233 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
6234 itype is visited, make an entry into table to link associated node and
6236 Add comments and correct harmless error in Build_NCT_Hash_Tables
6237 (Array_Aggr_Subtype): Associate each itype created for an index type to
6238 the corresponding range construct, and not to the aggregate itself. to
6239 maintain a one-to-one correspondence between itype and its associated
6240 node, to prevent errors when complex expression is copied.
6241 Fix mishandling of multiple levels of parens
6243 * sem_aggr.adb: Create a limited view of an incomplete type, to make
6244 treatment of limited views uniform for all visible declarations in a
6245 limited_withed package.
6246 (New_Copy_Tree): If hash table is being used and itype is visited,
6247 make an entry into table to link associated node and new itype.
6248 (Resolve_Record_Aggregate): Do not add an others box association for a
6249 discriminated record component that has only discriminants, when there
6250 is a box association for the component itself.
6252 * par-ch4.adb: Fix mishandling of multiple levels of parens
6254 2007-08-14 Robert Dewar <dewar@adacore.com>
6256 * comperr.adb: Fix problem with suppressing warning messages from gigi

6259 errout.adb (Write_Eol): Remove trailing spaces before writing the line
6260 (Write_Eol_Keep_Blanks): New procedure to write a line, including
6261 possible trailing spaces.
6262 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
6263 Fix problem with suppressing warning messages from back end
6264 Improve handling of deleted warnings
6267 Fix problem with suppressing warning messages from back end
6268 Handle setting of Static_Dispatch_Tables flag.

6287 Javier Miranda <miranda@adacore.com>
6288 Gary Dismukes <dismukes@adacore.com>
6290 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
6291 to make treatment of limited views uniform for all visible declarations
6292 in a limited_withed package.
6293 Improve warnings for in out parameters
6294 (Set_Related_Interaface/Related_Interface): Allow the use of this
6295 attribute with constants.
6296 (Write_Field26_Name): Handle attribute Related_Interface in constants.
6297 Warn on duplicate pragma Preelaborable_Initialialization
6299 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
6300 generation of a freezing node to ensure proper management of null
6301 excluding access types in the backend.
6302 (Create_Extra_Formals): Test base type of the formal when checking for
6303 the need to add an extra accessibility-level formal. Pass the entity E
6304 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
6305 originally being done in a couple of cases), to ensure that the
6306 Extra_Formals list gets set on the entity E when the first entity is
6308 (Conforming_Types): Add missing calls to Base_Type to the code that
6309 handles anonymous access types. This is required to handle the
6310 general case because Process_Formals builds internal subtype entities
6311 to handle null-excluding access types.
6312 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
6313 functions that need it, even when not marked Requires_Overriding.
6314 Improve warnings for in out parameters
6315 (Analyze_Function_Return): Warn for disallowed null return
6316 Warn on return from procedure with unset out parameter
6317 Ensure consistent use of # in error messages
6318 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
6319 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
6320 the implicit conversion of the expression done for anonymous access
6321 types. This is required to generate the code of the null excluding
6322 check (if required).
6324 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
6325 A formal parameter is never publicly referenceable outside of its body.
6326 (Check_References): For an unreferenced formal parameter in an accept
6327 statement, use the same warning circuitry as for subprogram formal
6329 (Warn_On_Unreferenced_Entity): New subprogram, taken from
6330 Output_Unreferenced_Messages, containing the part of that routine that
6331 is now reused for entry formals as described above.
6332 (Goto_Spec_Entity): New function
6333 (Check_References): Do not give IN OUT warning for dispatching operation
6334 Improve warnings for in out parameters
6335 (Test_Ref): Check that the entity is not undefinite before calling
6336 Scope_Within, in order to avoid infinite loops.
6337 Warn on return from procedure with unset out parameter
6338 Improved warnings for unused variables

6344 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
6345 (Expand_N_Attribute_Reference): Further unify the handling of the
6346 three forms of access attributes, using common code now for all three
6347 cases. Add a test for the case of applying an access attribute to
6348 an explicit dereference when the context is an access-to-interface
6349 type. In that case we need to apply the conversion to the prefix
6350 of the explicit dereference rather than the prefix of the attribute.
6351 (Attribute_Version, UET_Address): Set entity as internal to ensure
6352 proper dg output of implicit importation.
6353 (Expand_Access_To_Type): Removed.
6354 (Expand_N_Attribute_Reference): Merge the code from the three cases
6355 of access attributes, since the processing is largely identical for
6356 these cases. The substantive fix here is to process the case of a

6363 Robert Dewar <dewar@adacore.com>
6365 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
6366 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
6367 type that is an anonymous access to controlled object, establish
6368 an associated finalization chain to avoid corrupting the global
6369 finalization list when a dynamically allocated object designated
6370 by such a component is deallocated.

6392 (Freeze_Array_Type): Generate init proc for packed array if either
6393 Initialize or Normalize_Scalars is set.
6394 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
6395 constructing the new profile, copy the null_exclusion indicator for each
6396 parameter, to ensure full conformance of the new body with the spec.
6398 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
6399 Create wrappers for constructor functions that need it, even when not
6400 marked Requires_Overriding.

6433 types declared in the declarative part of a nested package body or in
6434 the proper body of a stub.

6440 output of implicit importation and exportation.
6441 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
6442 first formal of the thunk is always associated with the controlling
6443 type. In addition perform the following code cleanup: remove formal
6444 Thunk_Alias which is no longer required, cleanup evaluation of the
6445 the controlling type, and update the documentation.
6446 Replace occurrence of Default_Prim_Op_Count by

6458 (Make_Tags): New subprogram that generates the entities associated with
6459 the primary and secondary tags of Typ and fills the contents of Access_
6460 Disp_Table. In case of library-level tagged types imports the forward
6461 declaration of the primary tag that will be declared later by Make_DT.
6462 (Expand_Interface_Conversion): In case of access types to interfaces
6463 replace an itype declaration by an explicit type declaration to avoid
6464 problems associated with the scope of such itype in transient blocks.

6467 Ed Schonberg <schonberg@adacore.com>
6468 Javier Miranda <miranda@adacore.com>
6470 * exp_util.ads, exp_util.adb:
6471 This patch replaces a number of occurrences of explicit tests for N_Null
6472 with calls to Known_Null. This improves tracking of null values, since
6473 Known_Null also catches null constants, and variables currently known to
6474 be null, so we get better tracking.
6475 (Ensure_Defined): create an itype reference only in the scope of the
6477 (Side_Effect_Free): A selected component of an access type that
6478 denotes a component with a rep clause must be treated as not
6479 side-effect free, because if it is part of a linked structure its
6480 value may be affected by a renaming.
6481 (Expand_Subtype_From_Expr): For limited objects initialized with build
6482 in place function calls, do nothing; otherwise we prematurely introduce
6483 an N_Reference node in the expression initializing the object, which
6484 breaks the circuitry that detects and adds the additional arguments to
6485 the called function. Bug found working in the new patch for statically
6486 allocated dispatch tables.
6487 (Is_Library_Level_Tagged_Type): New subprogram.
6488 (Remove_Side_Effects): If the expression of an elementary type is an
6489 operator treat as a function call.
6490 (Make_Literal_Range): If the index type of the array is not integer, use
6491 attributes properly to compute the constraint on the resulting aggregate
6494 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
6495 class-wide type whose base type is an incomplete private type, leave
6496 class-wide type unfrozen so that freeze nodes can be generated
6497 properly at a later point.
6498 (Freeze_Entity, array case): Handle case of pragma Pack and component
6499 size attributre clause for same array.

7148 operations in Derive_Subprograms.
7149 (Collect_Previous_Instances): new procedure within of
7150 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
7151 unit being loaded, to ensure that the generation of global symbols is
7152 consistent in different compilation modes.
7153 (Is_Tagged_Ancestor): New function testing the ancestor relation that
7154 takes progenitor types into account.
7155 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
7156 traversing over the primitives of the formal and actual types to locate
7157 any abstract subprograms of the actual type that correspond to a
7158 nonabstract subprogram of the formal type's ancestor type(s), and issue
7159 an error if such is found.
7160 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
7161 Instantiate_Package_Body, Instantiate_Subprogram_Body):
7162 Remove bogus guard around calls to Inherit_Context.

7172 parameter to determine whether operation applies to the prefix.
7173 (Complete_Object_Operation): If actual has an access type and
7174 controlling formal is not an in_parameter, reject the actual if it is
7175 an access_to_constant type.
7176 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
7177 type, the candidate operations are found in the scope of declaration of
7178 the type, because the type has no primitive subprograms.
7179 (Analyze_Selected_Component): If prefix is class-wide, and root type is
7180 a private extension, only examine visible components before trying to
7181 analyze as a prefixed call.
7182 Change Entity_List to Type_To_Use, for better readability.
7183 (Has_Fixed_Op): Use base type when checking whether the type of an
7184 operator has a user-defined multiplication/division
7185 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
7186 user-defined operators are available for fixed-point types.

7191 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
7192 formal At_Any_Place indicating, when True, that we want to test for
7193 availability of the stream attribute at any place (as opposed to the
7194 current visibility context only).
7195 (Missing_Read_Write_Attributes): A stream attribute is missing for the
7196 purpose of enforcing E.2.2(8) only if it is not available at any place.
7197 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
7198 when checking the legality of an extension aggregate in a preelaborable
7199 package. Treat the literal null as a valid default expression in a
7200 component declaration for a type with preelaborable initialization.
7201 A limited interface is a legal progenitor for the designated type of a
7202 remote access to class-wide type.

7215 (Find_Selected_Component, Has_Components): Handle properly non-limited
7216 views that are themselves incomplete types.
7217 Handle interfaces visible through limited-with clauses.
7218 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
7219 subprogram generic actual for which we have generated a renaming.
7220 Warn when the renaming introduces a homonym of
7221 the renamed entity, and the renamed entity is directly visible.

7227 appear in the subtree to the current allocator if it is not a static
7229 (Resolve_Allocator): Perform cleanup if resolution has determined that
7230 the allocator is not a coextension.
7231 (Resolve): Skip an interpretation hidden by an abstract operator only
7232 when the type of the interpretation matches that of the context.
7233 (Resolve): When looping through all possible interpretations of a node,
7234 do not consider those that are hidden by abstract operators.
7235 (Resolve_Actuals): When verifying that an access to class-wide object
7236 is an actual for a controlling formal, ignore anonymous access to
7237 subprograms whose return type is an access to class_wide type.
7238 (Resolve_Slice): If the prefix of the slice is a selected component
7239 whose type depends on discriminants, build its actual subtype before
7240 applying range checks on the bounds of the slice.
7241 (Valid_Conversion): In an instance or inlined body, compare root types,
7242 to prevent anomalies between private and public views.
7243 (Resolve): Improve error message for ambiguous fixed multiplication
7244 expressions that involve universal_fixed multiplying operations.

7261 typecode parameters for a union (in a variant record), remove
7262 extraneous layer of Any wrapping for member label.
7263 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
7264 elabration statements, register the package with the name server
7265 at the beginning, not at the end, of the elaboration statements so
7266 that they can create remote access to subprogram values that designate
7267 remote subprograms from the package.
7269 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
7271 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
7272 values to compute the number of seconds since the Unix Epoc in order to
7273 account for Daylight Savings Time. Perform special processing for dates
7274 that are earlier than the Unix Epoc to obtain a negative number.

8359 System_Restrictions and initialization of the data unless there is
8360 some use of System.Restrictions in the partition.

8393 (Get_E_Length): Protect against bomb in case scope is standard
8394 (Selected_Range_Checks): If the node to be checked is a conversion to

8396 bounds of the slice to construct the required constraint checks.
8397 Improve NOT NULL error messages
8398 (Apply_Constraint_Check): If the context is a null-excluding access
8399 type, diagnose properly the literal null.

8414 Eric Botcazou <ebotcazou@adacore.com>
8415 Arnaud Charlet <charlet@adacore.com>
8417 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
8418 applicable to types that have the With_Type flag set. Returns the
8419 non-limited view of the type, if available, otherwise the type itself.
8420 For class-wide types, there is no direct link in the tree, so we have
8421 to retrieve the class-wide type of the non-limited view of the Etype.
8422 New attributes Static_Initialization and Static_Elaboration_Desired.
8423 Remove the pragma Thread_Body, and the associated flag
8424 Is_Thread_Body in entities, and all related code.
8425 (Suppress_Value_Tracking_On_Call): New flag

8433 (Related_Interface): New attribute. Present in dispatch table pointer
8434 components of records. Set to point to the entity of the corresponding
8436 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
8437 (Original_Access_Type): Remove, not needed.
8438 (Root_Type): Handle properly subtypes of class-wide-types.
8441 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
8442 class-wide types visible through limited-with clauses.
8443 (Try_Primitive_Operation): When examining all primitive operations of a
8444 tagged type, do not consider subprograms labeled as hidden unless they
8445 belong to a private generic type with a tagged parent.
8446 (Try_Object_Operation): Extensive rewriting, to handle properly various
8447 overloading cases, when several ancestors may have class-wide operations
8448 that are possible candidates, and when the overloaded functions return
8449 array types and have defaulted parameters so that the call may be
8450 interpreted as an indexing.
8451 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
8452 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
8453 successive actuals before analyzing the call itself.
8454 (Try_Primitive_Operation): A primitive operation is compatible with the
8455 prefix if the prefix has a synchronized type and the type of the formal
8456 is its corresponding record, as can be the case when the primitive
8457 operation is declared outside of the body of the type.
8458 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
8459 perform homonym traversal, looking for class-wide operation matches
8460 (formerly done in statements of Try_Class_Wide_Operation). Matches on
8461 access parameters are now restricted to anonymous access types.
8462 (Mark_Allocator): An allocator with a discriminant association parent is
8464 (Try_One_Prefix_Interpretation): If the type of the object is
8465 incomplete, as can be happen when it is a limited view obtained through
8466 a limited_with_clause, the selected component is not part of a prefixed
8468 (Complete_Object_Operation): Diagnose properly an object that is not
8469 aliased when the corresponding controlling formal is an access
8471 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
8472 ambiguous calls in prefixed notation, where two primitives differ only
8473 in that the controlling argument of one is an access parameter.
8475 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
8476 whether a function that returns an unconstrained type can be inlined.
8477 (Process_Formals): Diagnose properly the illegal use of an incomplete
8478 type in the profile of an access_to_subprogram declaration.
8479 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
8480 operations are attached to the corresponding record.
8481 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
8482 When processing a primitive of a concurrent type which implements an
8483 interface change the type of all controlling formals to that of the
8484 corresponding record type.
8485 (Check_Synchronized_Overriding): Relax the conditional logic when trying
8486 to determine the tagged type to which a primitive belongs.
8487 (Check_Conventions): Capture condition to ignore a primitive operation
8488 (which is shared between the loop in Check_Conventions and the one in
8489 Check_Convention) in a new local function Skip_Check.
8490 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
8491 confusion with Check_Conventions' own Prim_Op local variable.
8492 (Create_Extra_Formals): Test for a tagged result type rather than a
8493 controlling result when determining whether to add a BIP_Alloc_Form
8494 formal and a BIP_Final_List formal to the function.
8495 (Check_Conformance); For parameters that are anonymous access types,
8496 subtype conformance requires that the not null and the constant
8497 indicators must match
8498 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
8499 to retrieve the appropriate type when processing a concurrent type
8500 declared within a generic. Minor comment reformatting. Change invocation
8501 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
8503 (Analyze_Subprogram_Body): If the return type of a function is an
8504 anonymous access to the limited view of a class-wide type, and the
8505 non-limited view of the type is available, update the type of the
8506 function so that code can be generated.
8507 (Process_Formals): In case of access-subtype itype whose designated
8508 type is also an itype (situation that happens now with access to
8509 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
8510 attribute to avoid backend problems.
8511 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
8512 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
8513 anonymous types' designated types are same before testing
8514 Subtypes_Statically_Match.
8515 (Create_Extra_Formals): Test for a named access parameter that is a
8516 controlling formal as an additional condition for adding an
8517 accessibility level formal. This can occur in the subp type created for
8518 dispatching calls in Expand_Dispatching_Call, and allows calling
8519 Create_Extra_Formals from that procedure rather than special-casing the
8520 extra formals there.
8521 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
8522 when the function has a controlling result.
8523 (Check_Returns): Add much more knowledge of the optimization of local
8524 raise statements to gotos, to retain proper warnings in this case.
8525 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
8526 nodes when looking for last statement.
8528 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
8529 class-wide types visible through limited with clauses.
8530 (Add_One_Interp): If the operands are anonymous access types, the
8531 predefined operator on universal_access is immediately visibles
8532 (Find_Unique_Type): Handle anonymous access to subprogram types just as
8533 other anonymous access types.
8534 (Disambiguate): Take into account CIL convention.
8535 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
8537 2007-06-06 Robert Dewar <dewar@adacore.com>
8539 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
8540 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
8541 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
8542 Fix lower bound of tables.
8545 * nlists.adb: Ditto.
8546 (Prev_Node, Next_Node): Change index type to Int so that it properly
8547 covers the range First_Node_Id - 1 up.

8551 Bob Duff <duff@adacore.com>
8552 Hristian Kirtchev <kirtchev@adacore.com>
8554 * exp_aggr.ads, exp_aggr.adb:
8555 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
8556 in extension aggregates.
8557 (Flatten): Other conditions being met, an aggregate is static if the
8558 low bound given by component associations is different from the low
8559 bound of the base index type.
8560 (Packed_Array_Aggregate_Handled): If the component type is itself a
8561 packed array or record, the front-end must expand into assignments.
8562 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
8563 Init_Pr, instead of Ancestor_Is_Expression.
8564 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
8565 coextension chain root, either generate a list controller or use the
8566 already existing one.
8567 (Static_Array_Aggregate): New procedure to construct a positional
8568 aggregate that can be handled by the backend, when all bounds and
8569 components are compile-time known constants.
8570 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
8571 types covering interface types into assignments.
8572 (Replace_Type): move to Build_Record_Aggr_Code.
8573 (Expand_Record_Aggr_Code): if the target of the aggregate is an
8574 interface type, convert to the definite type of the aggregate itself,
8575 so that needed components are visible.
8576 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
8577 components and the context is an extended return statement do not
8578 create a transient block for it, to prevent premature finalization
8579 before the return is executed.
8580 (Gen_Assign): Do not generate a call to deep adjust routine if the
8581 component type is itself an array of controlled (sub)-components
8582 initialized with an inner aggregate.
8583 (Component_Check): New name for Static_Check. This name is now more
8584 appropriate, and documentation is added which was missing.
8585 (Component_Check): Add test for bit aligned component value
8586 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
8587 Tagged_Comps, name is more appropriate given added function below.
8588 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

8591 Javier Miranda <miranda@adacore.com>
8592 Robert Dewar <dewar@adacore.com>
8594 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
8595 Terminated: Add unchecked type conversion from System.Address to
8596 System.Tasking.Task_Id when calling the predefined primitive
8598 Disable new Ada 05 accessibility check for JVM.NET targets, which
8599 cannot be implemented in a practical way.
8600 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
8601 the sources always references the tag of the actual object. Therefore,
8602 if 'Tag is applied in the sources to class-wide interface objects we
8603 generate code that displaces "this" to reference the base of the object.
8604 (Expand_N_Attribute_Reference, case Size): Return specified size if
8606 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
8607 has code that displaces the pointer of the object to manage interface
8608 types. However this code must not be executed when the prefix is a
8609 subprogram. This bug caused the wrong expansion of the internally
8610 generated assignment that fills the dispatch table when the primitive
8611 is a function returning a class-wide interface type.
8612 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
8613 Set_Attribute_Name for Name_Unaligned_Valid.
8615 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8616 Gary Dismukes <dismukes@adacore.com>
8618 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
8619 If the initialization is the equivalent aggregate of the initialization
8620 procedure of the type, do not remove it.
8621 (Expand_N_Attribute_Definition_Clause): Exclude access variables
8622 initialized to null from having their expression reset to empty and
8623 note this exception in the comment.

8628 Gary Dismukes <dismukes@adacore.com>
8630 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
8631 Add "with" and "use" clauses for Sem_Attr.
8632 (Expand_Current_Value): Do not replace occurences of attribute
8633 references where the prefix must be a simple name.
8635 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for

8637 Attribute_Requires_Simple_Name_Prefix.
8638 (Name_Modifies_Prefix): Body of new function.
8639 (Requires_Simple_Name_Prefix): Body of new function.
8640 (Resolve_Attribute, case Access): Improve error message for case of
8641 mismatched conventions.
8642 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
8644 (Analyze_Attribute, case 'Access): If the type of the prefix is a
8645 constrained subtype for a nominal unconstrained type, use its base type
8646 to check for conformance with the context.
8647 (Resolve_Attribute): Remove test of the access type being associated
8648 with a return statement from condition for performing accessibility
8649 checks on access attributes, since this case is now captured by
8650 Is_Local_Anonymous_Access.
8651 (Analyze_Access_Attribute): Set Address_Taken on entity
8652 (Analyze_Attribute, case Address): Set Address_Taken on entity
8653 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
8654 validating an access attribute whose prefix is a current instance.
8655 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
8656 applied to dispatching operations, if freezing is required then we set
8657 the attribute Has_Delayed_Freeze in the prefix's entity.
8658 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
8659 current scope if access of local subprogram taken
8660 (Analyze_Access_Attribute): Check legality of self-reference even if the
8661 expression comes from source, as when a single component association in
8662 an aggregate has a box association.
8663 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
8664 the prefix if it is a protected operation and the attribute is
8665 Unrestricted_Access.
8666 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
8667 reference to the base type of the context, to force a constraint check
8668 when the context is an access subtype with an explicit constraint.
8669 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
8670 node is rewritten as an interface conversion. leave unanalyzed after
8671 resolution, to ensure that type checking against the context will take

8675 Javier Miranda <miranda@adacore.com>
8676 Robert Dewar <dewar@adacore.com>
8678 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
8679 wrapper when the full view of the controlling type of an inherited
8680 function that dispatches on result implements interfaces.
8681 (Expand_N_Object_Declaration): In cases where the type of the
8682 declaration is anonymous access, create finalization list for it.
8683 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
8684 if the object has no explicit initialization, to match description of
8685 functionality of pragam Persistent_BSS.
8686 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
8687 new function to build static aggregates, to replace initialization call
8688 when static initialization is desired.
8689 (Freeze_Type): Generate a list controller for an access type whenever
8690 its designated type has controlled anonymous access discriminants.
8691 (Build_Equivalent_Aggregate): New procedure to compute a static
8692 aggregate to be used as default initialization for composite types,
8693 instead of a generating a call to the initialization procedure for the
8695 (Build_Initialization_Call): When available, replace a call to the
8696 initialization procedure with a copy of the equivalent static aggregate
8698 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
8699 declarations for objects of a class-wide interface type, rather than
8700 just identifiers, to prevent visibility problems.
8701 (Expand_N_Object_Declaration): When expanding the declaration for an
8702 object of a class-wide interface type, preserve the homonym chain of
8703 the original entity before exchanging it with that of the generated
8704 renaming declaration.
8705 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
8706 active, because there is no way to handle the exception.
8707 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
8708 to do a minimum decoration of the Access_Disp_Table list.
8709 (Expand_Record_Controller): Avoid the addition of the controller between
8710 the component containing the tag of a secondary dispatch table and its
8711 adjacent component that stores the offset to the base of the object.
8712 This latter component is only generated when the parent type has
8713 discriminants ---documented in Add_Interface_Tag_Components).
8714 (Apply_Array_Size_Check): Removed, no longer needed.
8715 (Expand_N_Full_Type_Declaration): If the type has anonymous access
8716 components, create a Master_Entity for it only if it contains tasks.
8717 (Build_Init_Procedure): Suppress the tag assignment compiling under
8719 (Freeze_Record_Type): Remove code associated with creation of dispatch
8721 (Init_Secondary_Tags): Update type of actuals when generating calls to
8722 Ada.Tags.Set_Offset_To_Top
8723 (Stream_Operation_OK): Disable use of streams compiling under no
8725 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
8726 if Has_Init_Expression set.
8727 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
8728 Register_Primitive, which provides the same functionality.
8729 (Requires_Init_Proc): Return false in case of interface types.
8730 (Add_Secondary_Tables): Use the new attribute Related_Interface to
8732 (Predefined_Primitive_Freeze): Do not assume that an internal entity
8733 is always associated with a predefined primitive because the internal
8734 entities associated with interface types are not predefined primitives.
8735 Therefore, the call to Is_Internal is replaced by a call to the
8736 function Is_Predefined_Dispatching_Operation.
8737 (Make_Eq_If): When generating the list of comparisons for the
8738 components of a given variant, omit the controller component that is
8739 present if the variant has controlled components.
8741 2007-06-06 Javier Miranda <miranda@adacore.com>
8742 Hristian Kirtchev <kirtchev@adacore.com>
8743 Bob Duff <duff@adacore.com>
8745 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
8746 handle the creation of finalization lists and calls for nested
8747 coextensions when the root of the chains is part of a return statement.
8748 (Inside_A_Return_Statement): New function inside Complete_Coextension_
8750 (Expand_Record_Equality): Skip components that are interface types.
8751 (Displace_Allocator_Pointer): Add missing support for interface subtypes
8752 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
8753 with Rewrite_Coextension. Change the condition for detecting coextension
8755 (Is_Local_Access_Discriminant): Removed.
8756 (Rewrite_Coextension): New routine which rewrites a static coextension
8757 as a temporary and uses its unrestricted access in the construction of
8759 (Complete_Coextension_Finalization): New routine. Generate finalization
8760 attachment calls to all delayed coextensions.
8761 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
8762 the allocator is not a coextension itself and has delayed coextensions.
8763 If the current allocator is controlled, but also a coextension, delay
8764 the generation of the finalization attachment call.
8765 Rename local variable "Node" to "Nod" in order to avoid confusion with
8767 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
8768 limited types that are not inherently limited. Such an allocator is
8769 illegal, but is generated by the expander for a return statement, to
8770 copy the result onto the secondary stack. This is the only case where a
8771 limited object can be copied. Generate code to displace the pointer
8772 to the object if the qualified expression is a class-wide interface
8773 object. Such displacement was missing and hence the copy of the object
8775 (Apply_Accessibility_Check): Handle allocated objects initialized in
8777 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
8778 and Expand_Allocator_Expression. Allocating class-wide interface objects
8779 this routine displaces the pointer to the allocated object to reference
8780 the component referencing the corresponding secondary dispatch table.
8781 Expand_Allocator_Expression): Add missing support to allocate class-wide
8782 interface objects initialized with a qualified expression.
8783 (Get_Allocator_Final_List): Test for an anonymous access type that is a
8784 function result type, and use the finalization list associated with the
8785 function scope in that case (such an anonymous type should not be
8786 treated like an access parameter's type).
8788 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8789 Gary Dismukes <dismukes@adacore.com>
8790 Javier Miranda <miranda@adacore.com>
8792 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
8793 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
8794 required exception handler.
8795 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
8796 properly the case of a function whose return type is a limited
8797 class-wide interface type. Modify the code of the accessibility
8798 check to handle class-wide interface objects. In this case we need to
8799 displace "this" to reference the primary dispatch table to get access
8800 to the TSD of the object (to evaluate its accessibility level).
8801 (Expand_N_Extended_Return_Statement): Test for a tagged result type
8802 rather than a controlling result as one of the conditions for
8803 generating tests of the implicit BIP_Alloc_Form formal. The
8804 initialization assignment is also handled according to whether the
8805 result is tagged instead of controlling.
8806 In the case where the init assignment is inserted in the "then" part of
8807 the allocation conditional, rewrite the target to be a dereference of
8808 the implicit BIP_Object_Access formal.
8809 If the returned value is unconstrained and created on the secondary
8810 stack, mark the enclosing block and function so that the secondary
8811 stack is not reclaimed on return.
8812 Treat returns from functions with controlling results similarly to
8813 returns from functions with unconstrained result subtypes.
8814 If the object returned is unconstrained, and an allocator must be
8815 created for it, analyze the allocator once the block for the extended
8816 return is installed, to ensure that finalizable components
8817 of the expression use the proper finalization list. Guard the call to
8818 Move_Final_List with a check that there is something to finalize.
8819 (Make_Tag_Ctrl_Assignment): Use "old" handling
8820 of controlled type assignment for virtual machines, since new code uses
8821 unsupported features (such as direct access to bytes in memory).
8823 2007-06-06 Gary Dismukes <dismukes@adacore.com>
8824 Ed Schonberg <schonberg@adacore.com>
8826 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
8827 accessibility actual, check for the case of an aliased object that has
8828 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
8829 we fall into processing for the attribute rather than the name of the
8831 (Expand_Inline_Call): If an actual is a literal, and the corresponding
8832 formal has its address taken in the body, create a temporary to capture
8833 value. If the return type is a limited interface, do not treat the
8834 return value as Controlled.
8835 (Is_In_Place_Function): If the return type is a limited interface,
8836 treat as returning in place. The actual returned object may not always
8837 be limited, but the caller has to assume that it is returned in place.
8838 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
8839 context of an allocator, use the correct finalization chain (that is,
8840 the chain belonging to the access type, rather than the chain belonging
8841 to the current scope).
8842 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
8843 result type rather than a controlling result as a precondition for
8844 adding an allocation form actual to a build-in-place call.
8845 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
8846 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
8847 primitive in the dispatch tables. This work is now done by Make_DT when
8849 (Register_Predefined_DT_Entry): Removed.
8850 (Add_Return): If end label is not present, use sloc of last statement
8851 for generated return statement in procedure, for better gdb behavior
8853 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
8854 object address nodes to ensure proper processing by routines like
8856 (Expand_Call): Fix generation of validity check for parameter
8857 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
8858 the allocation form parameter if the result subtype is constrained,
8859 except when the function has a controlling result.
8860 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
8861 rather than Is_Controlled and Has_Controlled_Component, since we want to
8862 include class-wide result types in this treatment. Also test for a
8863 controlling result, since that also requires passing a finalization
8865 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
8866 even when the result subtype is constrained, to handle calls involving
8867 controlling results.
8868 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
8869 is now called even when the result subtype is constrained, to handle
8870 calls involving controlling results.
8871 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
8872 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
8873 now performs the test).
8874 (Make_Build_In_Place_Call_In_Object_Declaration):
8875 Add_Alloc_Form_Actual_* is now called even when the result subtype is
8876 constrained, to handle calls involving controlling results.
8877 (Add_Return): Accomodate rewritten pattern from local raise to goto
8878 transformation, so that we still recognize an transfer statement
8879 and do the right thing here in that case.
8880 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
8881 and end of subprogram code.
8882 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
8883 support for primitives that are functions (without formals) with a
8885 (Inherited_From_Formal): If the actual subtype has not generic parent
8886 type, it is not an actual for a formal derived type, and there is no
8887 operation to inherit from the formal.
8889 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8890 Thomas Quinot <quinot@adacore.com>
8892 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
8893 inserted cleanup code appropriately for GDB use.
8894 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
8895 exception handler for Deep_Adjust or Deep_Finalize.
8896 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
8897 Raise_From_Controlled_Operation is available, use a call to that
8898 subprogram instead of a plain "raise Program_Error" node to raise
8899 Program_Error if an exception is propagated from an Adjust or Finalize
8901 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
8902 appears in the optional statement list of a triggering alternative, the
8903 scope actions can be inserted directly there, and not in the list that
8904 includes the asynchronous select itself.
8906 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8907 Robert Dewar <dewar@adacore.com>
8908 Hristian Kirtchev <kirtchev@adacore.com>
8910 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
8911 generated exception handler appropriately when debugging generated code.
8912 Deal properly with No_Exception_Propagation restriction mode.
8913 (Expand_N_Abort_Statement): Add an unchecked type conversion from
8914 System.Address to System.Tasking.Task_Id when processing the result of
8915 the predefined primitive _disp_get_task_id.
8916 (Expand_N_Asynchronous_Select): Clarify comment.
8917 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
8918 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
8919 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
8920 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
8921 privals and for generated call to Complete_Entry_Body, for better gdb
8923 (Copy_Result_Type): Utility to construct a parameter and result profile
8924 for protected functions whose return type is an anonymous access to
8926 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
8928 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
8929 point when the local-raise-to-goto transformation has taken place.

8932 Nicolas Setton <setton@adacore.com>
8934 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
8935 functionality when the backend is generating code.
8936 Otherwise any serious error
8937 reported by the backend calling the frontend routine Error_Msg
8938 changes the Compilation_Mode to Check_Semantics, disables the
8939 functionality of this routine and causes the generation of
8940 spureous additional errors.
8942 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
8943 debugging information now generated by the compiler for fat-pointer
8945 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
8947 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
8949 2007-06-06 Thomas Quinot <quinot@adacore.com>

8952 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
8953 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
8954 For a remote call to a function with a classwide return type, apply an
8955 E.4(18) check to the returned value.
8956 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
8957 stream attributes of the designated type of an RACW, as they are not
8958 dispatching primitive operations.
8960 2007-06-06 Geert Bosch <bosch@adacore.com>
8962 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
8964 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
8966 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
8967 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
8969 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
8971 2007-06-06 Javier Miranda <miranda@adacore.com>
8973 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
8974 attribute compiling package Ada.Tags under No_Run_Time_Mode.
8976 2007-06-06 Javier Miranda <miranda@adacore.com>
8978 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
8979 deallocation of class-wide interface objects.
8980 (Expand_Dispatching_Constructor_Call): Take into account that if the
8981 result of the dispatching constructor is an interface type, the
8982 function returns a class-wide interface type; otherwise the returned
8983 object would be actual. The frontend previously accepted returning
8984 interface types because Expand_Interface_Actuals silently performed
8985 the management of the returned type "as if" it were a class-wide
8987 (Expand_Dispatching_Constructor_Call): Replace call to
8988 Make_DT_Access_Action by direct call to Make_Function_Call.
8990 2007-06-06 Robert Dewar <dewar@adacore.com>
8991 Ed Schonberg <schonberg@adacore.com>
8993 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
8994 compute masking constant, since we now set Esize properly to the
8996 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
8997 to match the alignment.
8998 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
8999 packed arrays of 8 bits or less.
9001 * freeze.adb (Freeze_Entity): When freezing the formals of a
9002 subprogram, freeze the designated type of a parameter of an access type
9003 only if it is an access parameter.
9004 Increase size of C convention enumeration object
9005 (Freeze_Entity, array type case): Make sure Esize value is properly
9006 adjusted for the alignment if it is known.
9007 (Freeze_Entity, array type case): When checking bit packed arrays for
9008 the size being incorrect, check RM_Size, not Esize.
9009 (Freeze_Record_Type): Check for bad discriminated record convention
9010 (In_Exp_Body): Return true if the body is generated for a subprogram
9011 renaming, either an attribute renaming or a renaming as body.
9012 (Check_Itype): If the designated type of an anonymous access component
9013 is a non-protected subprogram type, indicate that it is frozen, to
9014 prevent out-of-scope freeze node at some subsequent call.
9015 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
9016 only if the subprogram is neither imported nor exported, as well as the
9017 NCA descriptor class if the subprogram is exported.

9024 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
9025 default initialization on an imported object, when there is no
9026 initialization call generated for it.
9027 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
9030 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
9031 Static_Elaboration_Desired.

9033 Implement a new pragma No_Body
9034 Removes the Explicit_Overriding pragma
9035 Remove Optional_Overriding pragma

9037 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
9038 Pragma_CIL_Constructor): New names.
9040 * sem_cat.adb (Validate_Object_Declaration): An initialization that
9041 uses the equivalent aggregate of a type must be treated as an implicit
9043 (Get_Categorization): Check a unit for pragma Preelaborate only if it
9044 has none of the other categories.
9045 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
9046 to apply Import to an object renaming declaration.
9048 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
9049 from a C++ class should be declared as limited and that it will be
9050 considererd limited.
9051 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
9052 should be declared as limited and that it will be considererd limited.
9053 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
9054 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
9055 (Analyze_Pragma): Deal with Universal_Aliasing.
9056 (Sig_Flags): Likewise.
9057 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
9058 (Overflow_Checks_Unsuppressed): New flag.
9059 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
9060 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
9061 case of JVM or .NET targets, and compiling user code.
9062 Add debugging convenience routine rv

9066 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
9068 (Build_Elementary_Input_Call): For floating-point use right type in the
9069 absence of strange size or stream size clauses.
9070 (Build_Elementary_Write_Call): Same fix
9071 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
9072 set to value that does not match base type size.
9074 2007-06-06 Ed Schonberg <schonberg@adacore.com>
9076 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
9077 object of a limited type can be initialized with a call to a function
9078 that returns in place. If the limited type has unknown discriminants,
9079 and the underlying type is a constrained composite type, build an actual
9080 subtype from the function call, as is done for private types.
9081 (Side_Effect_Free): An expression that is the renaming of an object or
9082 whose prefix is the renaming of a object, is not side-effect free
9083 because it may be assigned through the renaming and its value must be
9084 captured in a temporary.
9085 (Has_Controlled_Coextensions): New routine.
9086 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
9087 as is done for other limited types.
9088 (Non_Limited_Designated_Type): new predicate.
9089 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
9091 Remove all handling of with_type clauses.
9093 * par-ch10.adb: Remove all handling of with_type clauses.
9095 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
9096 checksum if the main source could not be parsed.
9097 (Loat_Unit): When processing a child unit, determine properly whether
9098 the parent unit is a renaming when the parent is itself a child unit.
9099 Remove handling of with_type clauses.
9101 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

10712 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
10714 (Resolve_Actuals): If an actual is an allocator for an access parameter,
10715 the master of the created object is the innermost enclosing statement.
10716 (Remove_Conversions): For a binary operator, check if type of second

10951 "X'Unrestricted_Access = Y'Access" and so forth to match.

10959 attempt to derive from a synchronized tagged type.
10960 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
10961 type, inherit the class-wide type already created, because it may
10962 already have been used in a self-referential anonymous access component.
10963 (Mentions_T): Recognize self-referential anonymous access components
10964 that use (a subtype of) the class-wide type of the enclosing type.

10986 with abstract interfaces.
10987 (Analyze_Subtype_Indication): Resolve the range with the given subtype

11018 as the second switch, after -c.
11019 (Compile_Sources): Allow compilation of Annex J renames without -a
11020 (Is_In_Object_Directory): Check if the ALI file is in the object
11021 even if there is no project extension.
11022 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
11023 gnatbind if the ALI file effectively exists.
11024 (Initialize): Add the directory where gnatmake is invoked in front of
11025 the path if it is invoked from a bin directory, even without directory

11050 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
11051 when -gnatg is not specified.

11081 (Convert_Aggr_In_Allocator): If the allocator is for an access
11082 discriminant and the type is controlled. do not place on a finalization
11083 list at this point. The proper list will be determined from the

11086 initialize record controller if needed, before the components, to ensure
11087 that they are properly finalized.

11102 succeed in that case, even when the expression originates from a
11103 parameter of the containing subprogram.
11104 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
11105 under No_Dispatching_Calls restriction. During the semantic analysis
11106 we already notified such violation.
11107 (Tagged_Membership): Constant folding. There is no need to check
11108 the tag at run-time if the type of the right operand is non
11109 class-wide abstract.

11124 initialize most the TSD components by means of an aggregate.
11125 Modify the declaration of the object containing the TSD
11126 because we now expand code that has a higher level of abstraction.
11127 The TSD has a discriminant containing the Inheritance Depth Level,
11128 value that is used in the membership test but also to fix the size
11129 of the table of ancestors.
11130 (Expand_Interface_Conversion): Insert function body at the closest place
11131 to the conversion expression, to prevent access-before-elaboration
11132 errors in the backend.

11158 (Expand_Dispatching_Call): Replace generation of call to the run-time
11159 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
11160 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
11162 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
11163 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

11168 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
11171 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
11172 First (Parameter_Associations ()) with the call to First_Actual that
11173 returns an actual parameter expression for both named and positional

11177 check violation of restriction No_Dispatching_Calls.
11178 (Check_Controlling_Type): A formal of a tagged incomplete type is a
11179 controlling argument.

11182 First/Next_Component_Or_Discriminant
11183 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
11184 (Find_Implemented_Interface): Removed. All the calls to this subprogram
11185 specify Any_Limited_Interface, and this functionality is already
11186 provided by the function Has_Abstract_Interfaces.
11187 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
11188 support concurrent types implementing interfaces.
11189 (Find_Implemented_Interface): Removed. All the calls to this subprogram
11190 specify kind Any_Limited_Interface, and this functionality is already

11193 CW_Or_Controlled_Type whenever the issue is related to
11194 using or not the secondary stack.

11210 anonymous, use finalization list of enclosing dynamic scope.
11211 (Expand_N_Package_Declaration): For a library package declaration
11212 without a corresponding body, generate RACW subprogram bodies in the
11213 spec (just as we do for the task activation call).
11214 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
11215 Is_Abstract_Type. Make sure these are called only when appropriate.
11216 Remove all code for DSP option

11234 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
11235 a protected version of an operation declared in the private part of
11236 a protected object, because they may be invoked through a callback.
11237 (Set_Privals): If the type of a private component is an anonymous access
11238 type, do not create a new itype for each protected body.
11239 If the body of a protected operation creates
11240 controlled types (including allocators for class-widetypes), the
11241 body of the corresponding protected subprogram must include a

11248 for a possible overriding candidate.
11249 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
11250 hold an actual parameter value since its initialization is separated

11255 Pablo Oliveira <oliveira@adacore.com>
11257 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
11258 Do an Unchecked_Conversion to handle the passage from the Underlying

11260 Build_From_Any_Call.
11261 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
11262 E_Constant, depending upon Variable formal.
11263 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,

11268 the unit being compiled is the one that contains the stub type.
11269 Change primitive operation name for the RACW associated with a RAS
11270 from Call to _Call so it cannot clash with any legal identifier.
11271 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
11273 (Append_RACW_Bodies): New subprogram.
11274 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
11275 Add_Receiving_Stubs_To_Declarations functions.
11276 When expanding a package body, this list correspond to the

11281 registering the receiving stubs at the end of the 'Stmts' list.
11282 (RCI_Package_Locator): Pass the new Version generic formal when
11283 instantiating a RCI_Locator package.
11284 (Build_From_Any_Function): To compute the High bound for an
11285 unconstrained array actual, we add the Low bound with the length.
11286 Thus we must convert the low bound and the length to an appropriate
11287 type before doing the sum.
11288 (Build_Subprogram_Receiving_Stubs, PolyORB):
11289 * Retrieve the extra formals parameters at the
11290 end of the parameter stream.
11291 * Use Move_Any_Value to write back out parameters
11292 after executing the request as it is more efficient
11293 than Copy_Any_Value.
11294 * Build the any containing Extra Formals with the
11295 appropriate typecode.
11296 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
11297 empty Component_List.

11310 function with the first not implicit parent type.
11311 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
11312 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
11313 typecode from the Etype. Therefore we retrieve the correct typecode
11314 with a call to Get_Any_Type.
11315 (Copy_Specification): Do controlling formal type substitution based on
11316 Is_Controlling_Formal flag, instead of caller-provided object type.
11317 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
11318 a RACW primitive operation, we might get a subprogram declaration for an
11319 ancestor of the RACW designated type (not for the designated type
11320 itself), in the case where this operation is inherited. In this case we
11321 have no easy means of determining the original tagged type for which
11322 the primitive was declared, so instead we now rely on
11323 Copy_Specification to use the Is_Controlling_Formal flag to determine
11324 which formals require type substitution.

11332 handler unsuitable as a target for a local raise statement.
11333 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
11334 run-time subprogram CW_Membership by call to Build_CW_Membership.
11335 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
11336 by a function call, a temporary must be created before expanding the
11337 Constructor_Call itself, to prevent out-of-order elaboration in the
11338 back-end when stack checking is enabled..

11414 to be checked by gnatstack, which are the naming and the stack packages.
11415 (Check_Files): If no .ci files were specified for gnatstack we add all
11416 the .ci files belonging to the projects, including binder generated
11418 (Non_VMS_Usage): Document that gnatstack accept project file switches.
11419 (GNATCmd): Update the B_Start variable if we are in a VMS environment.
11420 Add gnatstack to the list of commands that use project file related
11421 switches, and get the single attribute Switches from the stack package
11422 in a project file when calling gnatstack. Parse the -U flag for
11423 processing files belonging to all projects in the project tree.
11424 Remove all processing for command Setup

11467 standard 8bits encoding.
11468 (WS2SU): As above but converting from wide-sring to string.
11469 This is needed as it is necessary to have access to both versions in the
11470 runtime for the form parameter encoding support.
11471 This set of patch add support for the encoding form parameter.
11472 (S2WS): Improve implementation to handle cases where the filename is not
11473 UTF-8 encoded. In this case we default to using the current code page
11474 for the conversion.
11476 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
11477 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

11521 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
11522 __gnat_adjust_context_for_raise.
11523 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
11524 implementation of floating point operations as native x86 targets.
11525 So the FPU should be initialized in the same way using finit. Fix
11526 floating point operations accuracy issues.
11527 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
11528 member in struct sigaction, so as to avoid warning for incompatible

11546 * lib-xref.ads, lib-xref.adb:
11547 Modify the loop that collects type references, to include interface
11548 types that the type implements. List each of these interfaces when
11549 building the entry for the type.
11550 (Generate_Definition): Initialize component Def and Typ of new entry
11551 in table Xrefs, to avoid to have these components unitialized.
11552 (Output_References): Split Is_Abstract flag into
11553 Is_Abstract_Subprogram and Is_Abstract_Type.
11554 (Generate_Reference): Add barrier to do not generate the warning
11555 associated with Ada 2005 entities with entities generated by the

11597 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
11598 it no longer destroys the contents of Name_Buffer or Name_Len and
11599 non-standard and invalid names are handled better.
11600 (Get_Decoded_Name_String): Improve performance by using
11601 Name_Has_No_Encodings flag in the name table.
11602 (Is_Valid_Name): New function to determine whether a Name_Id is valid.

11607 Bob Duff <duff@adacore.com>
11609 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
11610 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
11611 there is no need to generate always a record_definition_node in case
11612 of synchronized interface types.
11613 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
11614 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
11615 illegal in Ada 95, in cases where it is legal. Change the warnings to
11616 errors in other cases. Don't give the error unless the "not null"
11617 parses properly. Correct the source position at which the error occurs.
11618 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
11619 P_Null_Exclusion, to suppress "not null" warnings.

11671 Entry for pragma Unreferenced_Objects
11673 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
11674 switches, without repetition of "eD". Make sure that last character of
11675 -gnatep= switch is not taken as -gnat switch character.
11676 Complete rewrite of circuit for handling saving compilation options

11695 the default project path, initially done during elaboration of the
11697 If the prefix returned by Sdefault is null, get the prefix from a call
11698 to Executable_Prefix_Path.
11699 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
11702 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
11703 canonical directory name to open the directory from which files are
11705 (Record_Other_Sources): Idem.
11706 (Locate_Directory): Add the possibility to create automatically missing
11707 directories when Setup_Projects is True.

11710 library source copy dir and exec dir.
11712 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
11715 2007-04-06 Robert Dewar <dewar@adacore.com>

11755 Expand_Limited_With_Clause): Use a new copy of selector name in the
11756 call to Make_With_Clause. This fixes the tree structure for ASIS
11757 purposes. Nothing is changed in the compiler behaviour.
11758 (Process_Body_Clauses): Handle properly use clauses whose prefix is
11759 a package renaming.
11760 (Install_Limited_With_Clauses): Do not install non-limited view when it
11761 is still incomplete.
11763 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11764 Gary Dismukes <dismukes@adacore.com>
11766 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
11767 when capturing size information, instead of base type, which for a
11768 formal array type will be the unconstrained type.
11769 (Analyze_Formal_Object_Declaration): Add check for illegal default
11770 expressions for a formal in object of a limited type.
11771 (Instantiate_Object): Ditto.
11772 (Check_Formal_Package_Instance): Skip entities that are formal objects,
11773 because they were defaulted in the formal package and no check applies
11775 (Check_Formal_Package_Instance): Extend conformance check to other
11776 discrete types beyond Integer.
11777 (Process_Default): Copy directly the unmatched formal. A generic copy
11778 has already been performed in Analyze_Formal_Package.
11779 (Analyze_Associations): If a formal subprogram has no match, check for
11780 partial parametrization before looking for a default, to prevent
11782 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
11783 not set the instantiation environment before analyzing the actuals.
11784 Fixes regression on 8515-003 with implementation of AI-133.
11785 Set_Instance_Env checks whether the generic unit is a predefined
11786 unit, in which case the instance must be analyzed with the latest Ada
11787 mode. This setting must take place after analysis of the actuals,
11788 because the actuals must be analyzed and frozen in the Ada mode extant
11789 outside of the current instantiation.
11790 (Save_Env, Restore_Env): Preserve and restore the configuration
11791 parameters so that predefined units can be compiled in the proper Ada
11793 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
11794 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
11795 and Is_Abstract_Type.
11796 (Analyze_Formal_Package): For better error recovery, Add exception
11797 handler to catch Instantion_Error, which can be raised in
11798 Analyze_Associations

11801 Bob Duff <duff@adacore.com>
11802 Gary Dismukes <dismukes@adacore.com>
11804 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
11805 prefix type is a discriminated subtype of the type of the formal.
11806 (Analyze_Allocator): Collect all coextensions regardless of the context.
11807 Whether they can be allocated statically is determined in exp_ch4.
11808 (Analyze_Selected_Component): If the prefix is a limited view and the
11809 non-limited view is available, use the non-limited one.
11810 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
11811 therefore illegal), suggest a qualified expression rather than a type
11812 conversion, because a type conversion would be illegal in this context.
11813 (Anayze_Allocator): Trace recursively all nested allocators so that all
11814 coextensions are on the corresponding list for the root. Do no mark
11815 coextensions if the root allocator is within a declaration for a stack-
11816 allocated object, because the access discriminants will be allocated on
11818 (Analyze_Call): Remove restriction on calls to limited functions for the
11819 cases of generic actuals for formal objects, defaults for formal objects
11820 and defaults for record components.
11821 (Analyze_Allocator): Before analysis, chain coextensions on the proper
11822 element list. Their expansion is delayed until the enclosing allocator
11823 is processed and its finalization list constructed.
11824 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
11825 for an operation with the given name among the primitive operations of
11826 the corresponding record type.
11827 (Analyze_Selected_Component): If the prefix is a task type that
11828 implements an interface, and there is no entry with the given name,
11829 check whether there is another primitive operation (e.g. a function)
11831 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
11832 properly the indexing of a function call written in prefix form, where
11833 the function returns an array type, and all parameters of the function
11834 except the first have defaults.
11835 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
11836 the original operands, rather than relocating them, for efficiency and
11837 to work properly when an operand is overloaded.
11838 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
11839 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
11840 (Analyze_Selected_Component): If the prefix is a private extension, only
11841 scan the visible components, not those of the full view.
11842 (Try_Primitive_Operation): If the operation is a procedure, collect all
11843 possible interpretations, as for a function, because in the presence of
11844 classwide parameters several primitive operations of the type can match
11845 the given arguments.

11856 Thomas Quinot <quinot@adacore.com>
11858 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move

11876 a RAS as Comes_From_Source to get proper view switching when installing
11877 private declarations.
11878 Provite a placeholder nested package body along with the nested spec
11879 to have a place for Append_RACW_Bodies to generate the calling stubs
11880 and stream attributes.

11911 object O, use the access level of O.
11912 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
11913 rather than local Same_Formal_Type, to check whether protected operation
11914 overrides an inherited one.
11915 (Same_Formal_Type): New predicate, used when matching signatures of
11916 overriding synchronized operations, to handle the case when a formal
11917 has a type that is a generic actual.
11918 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
11919 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.

11935 same result than Is_Ancestor.
11936 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
11937 (Collect_Synchronized_Interfaces): Removed because the subprogram
11938 Collect_Abstract_Interfaces provides this functionality.

11940 concurrent types and thus avoid undesired code duplication.
11941 (Get_Subprogram_Entity): Handle entry calls.

11984 high bound is constant and the slice is empty. Tidy.
11985 (tree_transform, case N_Op_Not): Handle properly the case where the
11986 operation applies to a private type whose full view is a modular type.
11987 (Case_Statement_To_gnu): If an alternative is an E_Constant with an

11989 representing the choice value to ensure the corresponding GCC tree is
11990 of the proper kind.
11991 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
11992 instead of just the operands, as the base GCC stabilize_reference does.
11993 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
11994 requested; otherwise fail.
11995 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

12255 (mainly static expression evaluation).
12256 Reword some continuation messages
12257 Add some \\ sequences to continuation messages
12258 (Resolve_Call): Refine infinite recursion case. The test has been

12274 Valid_Conversion, to incorporate accessibility checks for arrays of
12275 anonymous access types.
12276 (Valid_Conversion): For a conversion to a numeric type occurring in an
12277 instance or inlined body, no need to check that the operand type is
12278 numeric, since this has been checked during analysis of the template.

12744 (__gnat_set_globals): Now a dummy function.
12745 (__gnat_handle_vms_condition): Feed adjust_context_for_raise with
12746 mechargs instead of sigargs, as the latter can be retrieved from the

12793 sem_util and renamed as Collect_All_Abstract_Interfaces.
12794 (Set_All_DT_Position): Hidden entities associated with abstract
12795 interface primitives are not taken into account in the check for

12798 interfacing with CPP by default.
12799 (Expand_Interface_Conversion): Add missing support for static conversion

12807 alias of a predefined dispatching primitive.
12808 (Make_DT): If the ancestor of the type is a CPP_Class and we are
12809 compiling under full ABI compatibility mode we avoid the generation of
12810 calls to run-time services that fill the dispatch tables because under
12811 this mode we currently inherit the dispatch tables in the IP subprogram.
12812 (Write_DT): Emit an "is null" indication for a null procedure primitive.
12813 (Expand_Interface_Conversion): Use an address as the type of the formal
12814 of the internally built function that handles the case in which the

12865 we request a discriminal value only in case of discriminants.
12866 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
12867 assignments where the target subtype is unconstrained and the target
12868 object is a parameter or dereference (other aliased cases are known

12985 are build-in-place function calls.
12986 (Replace_Self_Reference): New subsidiary of
12987 Make_OK_Assignment_Statement, to replace an access attribute that is a
12988 self-reference into an access to the appropriate component of the
12989 target object. Generalizes previous mechanism to handle self-references
12990 nested at any level.
12991 (Is_Self_Referential_Init): Remove, not needed.

12998 default initialization.
12999 (Make_OK_Assignment_Statement): If the expression is of the form
13000 Typ'Acc, where Acc is an access attribute, the expression comes from a
13001 default initialized self-referential component.
13002 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
13003 that has been derived from several abstract interfaces we must also

13012 (Expand_Access_To_Protected_Op): If the context indicates that an access
13013 to a local operation may be transfered outside of the object, create an
13014 access to the wrapper operation that must be used in an external call.
13015 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
13016 target, pass the Valid attribute applied to a floating-point prefix on
13017 to the back end without expansion.

13032 subcomponent's enclosing variable is aliased with a constrained subtype.
13033 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
13034 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
13035 an aliased prefix must be known to be constrained in order to use True
13036 for the attribute value, and now it's possible for some aliased views
13037 to be unconstrained.

13056 required to report the correct error message.
13057 (Expand_N_Subtype_Indication): Do validity checks on range
13058 (Clean_Task_Names): If an initialization procedure includes a call to

13067 call to build-in-place function and apply Make_Build_In_Place_Call_In_
13068 Object_Declaration to the call.
13069 (Freeze_Type): When the designated type of an RACW was not frozen at the
13070 point where the RACW was declared, validate the primitive operations
13071 with respect to E.2.2(14) when it finally is frozen.
13072 (Build_Initialization_Call,Expand_Record_Controller): Rename
13073 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
13074 return-by-reference has no meaning in Ada 2005.

13076 to register tag of the immediate ancestor interfaces in the
13077 run-time structure.

13079 initialization of extension aggregates with abstract interfaces.
13080 (Build_Master_Renaming): Make public, for use by function declarations
13081 whose return type is an anonymous access type.
13082 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
13083 Insert_List_Before_And_Analyze after the generation of the specs
13084 associated with null procedures.

13086 (Init_Secondary_Tags): Update documentation.
13087 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
13088 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
13089 then generate code to inherit the contents of the dispatch table
13090 directly from the ancestor.
13091 (Expand_Record_Controller): Insert controller component after tags of
13092 implemented interfaces.
13093 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to

13097 declarations for overriding null primitives inherited from interfaces.
13098 (Is_Null_Interface_Procedure): New function in
13099 Make_Null_Procedure_Specs.
13100 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
13101 immediate ancestor of a tagged type is an abstract interface type we
13102 must generate the specification of the predefined primitives associated
13103 with controlled types (because the dispatch table of the ancestor is
13104 null and hence these entries cannot be inherited). This is required to
13105 elaborate well the dispatch table.

13119 the maximum for type T.
13120 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
13121 when the allocator is initialized by a build-in-place call, since the
13122 allocator is already rewritten as a reference to the function result,
13123 and this prevents an unwanted duplication of the function call.
13124 Add with and use of Exp_Ch6.
13125 (Expand_Allocator_Expresssion): Check for an allocator whose expression
13126 is a call to build-in-place function and apply
13127 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
13128 untagged designated types).
13129 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
13130 optimization if source or target is biased.
13131 (Expand_N_Allocator): Add comments for case of an allocator within a

13144 (Expand_N_Assignment_Statement): Call
13145 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a

13149 in order to alleviate the upward compatibility introduced by AI-318.

13151 return object as a build-in-place result.
13152 (Expand_Non_Function_Return): Implement simple return statements nested
13153 within an extended return.
13154 (Enable_New_Return_Processing): Turn on the new processing of return
13156 (Expand_Non_Function_Return): For a return within an extended return,

13164 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
13165 validity checking of assignments to elementary record components.
13166 (Expand_N_Return_Statement): return Class Wide types on the secondary
13167 stack independantly of their controlled status since with HIE runtimes,
13168 class wide types are not potentially controlled anymore.
13170 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
13173 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
13174 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
13175 it expects a block, procedure, or task. The return statement will get
13176 turned into a block, and Expand_Cleanup_Actions will happen then.

13185 (Expand_Inlined_Call): Tagged types are by-reference types, and
13186 therefore should be replaced by a renaming declaration in the expanded
13187 body, as is done for limited types.
13188 (Expand_Call): If this is a call to a function with dispatching access
13189 result, propagate tag from context.
13190 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
13192 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
13193 build-in-place when the right-hand side of an assignment is a
13194 build-in-place function call.
13195 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
13196 of the explicit dereference of the allocator to the result subtype of
13197 the build-in-place function. This is needed to satisfy type checking
13198 in cases where the caller's return object is created by an allocator for
13199 a class-wide access type and the type named in the allocator is a
13201 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
13202 conversion of the reference to the declared object to the result subtype
13203 of the build-in-place function. This is needed to satisfy type checking
13204 in cases where the declared object has a class-wide type. Also, in the
13205 class-wide case, change the type of the object entity to the specific
13206 result subtype of the function, to avoid passing a class-wide object
13207 without explicit initialization to the back end.
13208 (Register_Interface_DT_Entry): Moved outside the body of
13209 Freeze_Subprogram because this routine is now public; it is called from
13210 Check_Dispatching_Overriding to handle late overriding of abstract
13211 interface primitives.
13212 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
13213 adding an implicit access actual on a call to a build-in-place function.
13214 (Expand_Actuals): Test for an actual parameter that is a call to a
13215 build-in-place function and apply
13216 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
13217 (Is_Build_In_Place_Function): New function to determine whether an
13218 entity is a function whose calls should be handled as build-in-place.
13219 (Is_Build_In_Place_Function_Call): New function to determine whether an
13220 expression is a function call that should handled as build-in-place.
13221 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
13222 calls to build-in-place functions as the initialization of an allocator.
13223 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
13224 handling calls to build-in-place functions in contexts that do not
13225 involve init of a separate object (for example, actuals of subprogram
13227 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
13228 handling calls to build-in-place functions as the initialization of an
13229 object declaration.
13230 (Detect_Infinite_Recursion): Add explicit parameter Process to
13231 instantiation of Traverse_Body to avoid unreferenced warning.
13232 (Check_Overriding_Inherited_Interfaces): Removed.
13233 (Register_Interface_DT_Entry): Code cleanup.
13234 (Register_Predefined_DT_Entry): Code cleanup.
13235 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
13236 inlined statements if within a transient scope.
13237 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
13238 formal parameters with occurrences of actuals in inlined body, establish
13239 visibility on the proper view of the actual's subtype for the body's
13241 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
13242 compatibility mode and we have an imported CPP subprogram because
13243 for now we assume that imported CPP primitives correspond with
13244 objects whose constructor is in the CPP side (and therefore we
13245 don't need to generate code to register them in the dispatch table).
13246 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
13247 aligned selected component.
13248 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
13249 the actual of an in-mode parameter is a type conversion.
13250 (Expand_Actuals): If the call does not come from source and the actual
13251 is potentially misaligned, let gigi handle it rather than rejecting the
13252 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
13253 Class Wide types as returning by reference independantly of their
13254 controlled status since with HIE runtimes class wide types are not
13255 potentially controlled anymore.
13257 2006-10-31 Ed Schonberg <schonberg@adacore.com>
13259 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
13260 references that are private components of the protected object.
13261 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
13262 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
13263 instantiation to deal with warnings.
13264 (Initialize_Protection): If expression for priority is non-static, use
13265 System_Priority as its expected type, in case the expression has not
13268 2006-10-31 Robert Dewar <dewar@adacore.com>
13270 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
13271 initialization of Homonym_Len.
13272 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
13273 names from fully qualified name. Fixes problem of duplicate
13274 external names differing only in the presence of such a block name.
13276 2006-10-31 Thomas Quinot <quinot@adacore.com>
13277 Pablo Oliveira <oliveira@adacore.com>
13279 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
13280 subprogram Ids, even if they are not yet assigned.
13281 (Build_Subprogram_Id): It is now this function that will take care of
13282 calling Assign_Subprogram_Ids if necessary.
13283 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
13284 should be done only once they are assigned.
13285 (Build_From_Any_Function, case of tagged types): Add missing call to
13287 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
13288 type for an RACW type.
13289 (Add_RACW_Features): When processing an RACW declaration for which the
13290 designated type is already frozen, enforce E.2.2(14) rules immediately.
13291 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
13292 special reordering of controlling formals.
13294 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
13295 associated stub type for an RACW type.
13297 2006-10-31 Ed Schonberg <schonberg@adacore.com>
13299 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
13300 fixed-point operations in an integer context, i.e. as operands of a
13301 conversion to an integer type, indicate that result must be rounded.
13303 2006-10-31 Robert Dewar <dewar@adacore.com>
13305 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
13306 cases, pass the encoding method, since it is now required by the run
13309 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
13310 assumption that Str'First = 1.
13311 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
13312 it on to the Value_Wide_Wide_Character call.
13313 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
13314 properly handles a string of the form quote-encoded_wide_char-quote.
13316 * s-wchcnv.adb: Minor reformatting
13318 2006-10-31 Javier Miranda <miranda@adacore.com>
13320 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
13321 run-time membership test to ensure that the constructed object
13322 implements the target abstract interface.
13324 2006-10-31 Robert Dewar <dewar@adacore.com>
13326 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
13327 Machine_Attribute pragma internally to implement the user pragma.
13328 Add processing for pragma Interface so that it is now completely
13329 equivalent to pragma Import.
13331 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
13332 so that it can be applied to all entities, including record components
13333 and enumeration literals.
13334 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
13335 priority ranges are correct, verify compatibility against task
13336 dispatching and locking policies, and if everything is correct an entry
13337 is added to the table containing priority specific dispatching entries
13338 for this compilation unit.
13339 (Delay_Config_Pragma_Analyze): Delay processing
13340 Priority_Specific_Dispatching pragmas because when processing the
13341 pragma we need to access run-time data, such as the range of
13342 System.Any_Priority.
13343 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
13344 Allow pragma Unreferenced as a context item
13345 Add pragma Preelaborable_Initialization
13346 (Analyze_Pragma, case Interface): Interface is extended so that it is
13347 now syntactically and semantically equivalent to Import.
13348 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
13349 insertion characters.
13350 Add handling for Pragma_Wide_Character_Encoding
13351 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
13352 never supercedes a real restriction, and that a real restriction
13353 always supercedes a warning.
13354 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
13357 2006-10-31 Bob Duff <duff@adacore.com>
13358 Ed Schonberg <schonberg@adacore.com>
13359 Robert Dewar <dewar@adacore.com>
13361 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
13362 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
13363 Is_Inherently_Limited_Type, because return-by-reference has no meaning
13365 (Find_Node_To_Be_Wrapped): Use new method of determining the result
13366 type of the function containing a return statement, because the
13367 Return_Type field was removed. We now use the Return_Applies_To field.
13369 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
13370 (Build_Task_Image_Decl): If procedure is not called from an
13371 initialization procedure, indicate that function that builds task name
13372 uses the sec. stack. Otherwise the enclosing initialization procedure
13373 will carry the indication.
13374 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
13375 N_Object_Declaration instead.
13376 (Kill_Dead_Code): New interface to implement -gnatwt warning for
13377 conditional dead code killed, and change implementation accordingly.
13378 (Insert_Actions): Add N_Return_Object_Declaration case.
13379 Correct comment to mention N_Extension_Aggregate node.
13380 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
13381 attempts to save information for global variables which cannot be
13383 (Get_Current_Value_Condition): Handle conditions the other way round
13384 (constant on left). Also handle right operand of AND and AND THEN
13385 (Set_Current_Value_Condition): Corresponding changes
13386 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
13387 (Get_Current_Value_Condition): Handle simple boolean operands
13388 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
13389 (Get_Current_Value_Condition): If the variable reference is within an
13390 if-statement, does not appear in the list of then_statments, and does
13391 not come from source, treat it as being at unknown location.
13392 (Get_Current_Value_Condition): Enhance to allow while statements to be
13393 processed as well as if statements.
13394 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
13396 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
13397 of loop. This is safe now that we fixed Kill_Current_Values.
13398 (OK_To_Do_Constant_Replacement): Check whether current scope is
13399 Standard, before examining outer scopes.
13401 2006-10-31 Vincent Celier <celier@adacore.com>
13403 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
13404 When True, apply VMS treatment to children of packages A, G, I and S.
13407 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
13409 2006-10-31 Robert Dewar <dewar@adacore.com>
13410 Ed Schonberg <schonberg@adacore.com>
13412 * freeze.adb: Add handling of Last_Assignment field
13413 (Warn_Overlay): Supply missing continuation marks in error msgs
13414 (Freeze_Entity): Add check for Preelaborable_Initialization
13416 * g-comlin.adb: Add Warnings (Off) to prevent new warning
13418 * g-expect.adb: Add Warnings (Off) to prevent new warning
13420 * lib-xref.adb: Add handling of Last_Assignment field
13421 (Generate_Reference): Centralize handling of pragma Obsolescent here
13422 (Generate_Reference): Accept an implicit reference generated for a
13423 default in an instance.
13424 (Generate_Reference): Accept a reference for a node that is not in the
13425 main unit, if it is the generic body corresponding to an subprogram
13428 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
13430 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
13432 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
13434 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
13435 use clauses, to avoid messages on packages used to qualify, and also
13436 to avoid messages from obsolescent units.
13437 (Warn_On_Useless_Assignments): Don't generate messages for imported
13438 and exported variables.
13439 (Warn_On_Useless_Assignments): New procedure
13440 (Output_Obsolescent_Entity_Warnings): New procedure
13441 (Check_Code_Statement): New procedure
13443 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
13444 Change name Is_Ada_2005 to Is_Ada_2005_Only
13445 (Last_Assignment): New field for useless assignment warning
13447 2006-10-31 Olivier Hainque <hainque@adacore.com>
13449 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
13450 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
13452 2006-10-31 Bob Duff <duff@adacore.com>
13453 Robert Dewar <dewar@adacore.com>
13454 Ed Schonberg <schonberg@adacore.com>
13456 * g-awk.adb (Default_Session, Current_Session): Compile this file in
13457 Ada 95 mode, because it violates the new rules for AI-318.
13459 * g-awk.ads: Use overloaded subprograms in every case where we used to
13460 have a default of Current_Session. This makes the code closer to be
13461 correct for both Ada 95 and 2005.
13463 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
13464 code, relying on the fact that the compiler generates a warning
13465 instead of an error in -gnatg mode.
13467 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
13468 E_Return_Statement entity kind.
13469 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
13471 * par.adb (P_Interface_Type_Definition): Addition of one formal to
13472 report an error if the reserved word abstract has been previously found.
13473 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
13475 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
13476 parenthesized range attribute usage
13477 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
13479 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
13480 in the syntax for extended_return_statement. This is not in the latest
13481 RM, but the ARG is expected to issue an AI allowing this.
13482 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
13483 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
13484 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
13485 P_Return_Statement): Parse the new syntax for extended_return_statement.
13487 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
13488 Output_End_Missing): Add error-recovery code for the new
13489 extended_return_statement syntax; that is, the new E_Return entry on
13492 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
13493 limited to nonlimited, because otherwise we violate the new Ada 2005
13494 rules about returning limited types in function Create_AST_Handler in
13497 * sem.adb (Analyze): Add cases for new node kinds
13498 N_Extended_Return_Statement and N_Return_Object_Declaration.
13500 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
13501 type is in the same category as type of context before applying check,
13502 to prevent anomalies in instantiations.
13503 (Resolve_Aggregate): Remove test for limited components in aggregates.
13504 It's unnecessary in Ada 95, because if it has limited components, then
13505 it must be limited. It's wrong in Ada 2005, because limited aggregates
13507 (Resolve_Record_Aggregate): Move check for limited types later, because
13508 OK_For_Limited_Init requires its argument to have been resolved.
13509 (Get_Value): When copying the component default expression for a
13510 defaulted association in an aggregate, use the sloc of the aggregate
13511 and not that of the original expression, to prevent spurious
13512 elaboration errors, when the expression includes function calls.
13513 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
13514 were missing. We also didn't handle qualified expressions. Now also
13515 allow function calls. Use new common routine OK_For_Limited_Init.
13516 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
13517 with space can upper case letter).
13519 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
13520 Has_Static_Discriminants flag
13521 (Record_Type_Declaration): Diagnose an attempt to declare an interface
13522 type with discriminants.
13523 (Process_Range_Expr_In_Decl): Do validity checks on range
13524 (Build_Discriminant_Constraints): Use updated form of
13525 Denotes_Discriminant.
13526 (Process_Subtype): If the subtype is a private subtype whose full view
13527 is a concurrent subtype, introduce an itype reference to prevent scope
13529 (Build_Derived_Record_Type, Collect_Interface_Primitives,
13530 Record_Type_Declaration): The functionality of the subprograms
13531 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
13532 is now performed by a single routine.
13533 (Build_Derived_Record_Type): If the type definition includes an explicit
13534 indication of limitedness, then the type must be marked as limited here
13535 to ensure that any access discriminants will not be treated as having
13536 a local anonymous access type.
13537 (Check_Abstract_Overriding): Issue a detailed error message when an
13538 abstract subprogram was not overridden due to incorrect mode of its
13540 (Analyze_Private_Extension_Declaration): Add support for the analysis of
13541 synchronized private extension declarations. Verify that the ancestor is
13542 a limited or synchronized interface or in the generic case, the ancestor
13543 is a tagged limited type or synchronized interface and all progenitors
13544 are either limited or synchronized interfaces.
13545 Derived_Type_Declaration): Check for presence of private extension when
13546 dealing with synchronized formal derived types.
13547 Process_Full_View): Enchance the check done on the usage of "limited" by
13548 testing whether the private view is synchronized.
13549 Verify that a synchronized private view is completed by a protected or
13551 (OK_For_Limited_Init_In_05): New function.
13552 (Analyze_Object_Declaration): Move check for limited types later,
13553 because OK_For_Limited_Init requires its argument to have been resolved.
13554 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
13555 in order to alleviate the upward compatibility introduced by AI-318.
13556 (Constrain_Corresponding_Record): If the constraint is for a component
13557 subtype, mark the itype as frozen, to avoid out-of-scope references to
13558 discriminants in the back-end.
13559 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
13560 this subprogram against wrong sources.
13561 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
13562 discriminant of limited type completed with a protected type, when the
13563 discriminant is used to constrain a private component of the type, and
13564 expansion is disabled.
13565 (Find_Type_Of_Object): Do not treat a return subtype that is an
13566 anonymous subtype as a local_anonymous_type, because its accessibility
13567 level is the return type of the enclosing function.
13568 (Check_Initialization): In -gnatg mode, turn the error "cannot
13569 initialize entities of limited type" into a warning.
13570 (OK_For_Limited_Init): Return true for generated nodes, since it
13571 sometimes violates the legality rules.
13572 (Make_Incomplete_Declaration): If the type for which an incomplete
13573 declaration is created happens to be the currently visible entity,
13574 preserve the homonym chain when removing it from visibility.
13575 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
13576 inherited subprograms.
13577 (Access_Definition): If this is an access to function that is the return
13578 type of an access_to_function definition, context is a type declaration
13579 and the scope of the anonymous type is the current one.
13580 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
13581 incomplete subtype to the set of private dependents of the original
13583 (Constrain_Discriminated_Type): Emit an error message whenever an
13584 incomplete subtype is being constrained.
13585 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
13586 corresponding subtype of the full view of the original incomplete type.
13587 (Check_Incomplete): Properly detect invalid usage of incomplete types
13590 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
13592 * g-catiio.ads, g-catiio.adb (Value): New function.
13593 Given an input String, try and parse a valid Time value.
13595 2006-10-31 Vincent Celier <celier@adacore.com>
13597 * g-debpoo.adb (Is_Valid): Correctly compute Offset using
13598 Integer_Address arithmetic, as in Set_Valid.
13600 2006-10-31 Arnaud Charlet <charlet@adacore.com>
13601 Robert Dewar <dewar@adacore.com>
13603 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
13604 handling executable extension manually and duplicating code.
13606 * make.adb: Implement new -S switch
13607 (Gnatmake): Use new function Osint.Executable_Name instead
13608 of handling executable extension manually.
13610 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
13611 is specified, the executable name ends with this suffix.
13612 Take advantage of Osint.Executable_Name instead of duplicating code.
13614 * switch-m.adb: Recognize new gnatmake -S switch
13616 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
13618 (Get_Target_Parameters): Set Executable_Extension_On_Target if
13621 * makeusg.adb: Add line for gnatmake -S switch
13623 2006-10-31 Vincent Celier <celier@adacore.com>
13625 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
13626 call it with -static-libgcc, as there are some platforms, such as
13627 Darwin, where one of these two switches is compulsory to link.
13629 2006-10-31 Vincent Celier <celier@adacore.com>
13631 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
13632 instead of ADA_PROJECT_PATH, for the project path.
13633 (Gnatls): When displaying the project path directories, use host dir
13636 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
13637 names in the project path, as absolute paths may correspond to
13638 multi-valued VMS logical names.
13640 2006-10-31 Vincent Celier <celier@adacore.com>
13642 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
13643 absolute path name.
13644 (Locate_Regular_File): Ditto
13645 (Change_Dir): Remove, no longer used
13646 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
13647 on Windows. Get it calling Get_Current_Dir.
13648 (OpenVMS): Remove imported boolean, no longer needed.
13649 (Normalize_Pathname)[VMS]: Do not resolve directory names.
13650 (Pid_To_Integer): New function to convert a Process_Id to Integer

13667 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
13669 2006-10-31 Robert Dewar <dewar@adacore.com>
13671 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
13673 (Layout_Variant_Record): Retrieve the discriminants from the entity
13674 rather than from the type definition, because in the case of a full
13675 type for a private type we need to take the discriminants from the
13677 (Layout_Component_List): When applying the Max operator to variants with
13678 a nonstatic size, check whether either operand is static and scale that
13679 operand from bits to storage units before applying Max.
13680 (Layout_Type): In VMS, if a C-convention access type has no explicit
13681 size clause (and does not inherit one in the case of a derived type),
13682 then the size is reset to 32 from 64.
13684 2006-10-31 Vincent Celier <celier@adacore.com>
13686 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
13687 its file has already been loaded, according to the unit being loaded,
13688 not to the current value of Multiple_Unit_Index.
13690 2006-10-31 Thomas Quinot <quinot@adacore.com>
13691 Eric Botcazou <ebotcazou@adacore.com>
13692 Arnaud Charlet <charlet@adacore.com>
13694 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
13695 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
13697 (a-except.o): Pass it to the compiler.
13698 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.

13706 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
13708 * Make-lang.in: Remove all references to gt-ada-decl.h.
13709 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
13711 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.

13718 * mlib-utl.adb (Initialized): Remove, no longer used
13719 (Initialize): Remove, no longer used
13720 (Ar): If Ar_Exec is null, get the location of the archive builder and,

13723 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
13726 2006-10-31 Ed Schonberg <schonberg@adacore.com>
13728 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
13729 Process_Body_Clauses): If the context of a body includes a use clause
13730 for P.Q then a with_clause for P in the same body is not redundant,
13731 even if the spec also has a with_clause on P.
13732 Add missing continuation mark to error msg
13733 (Build_Limited_Views): A limited view of a type is tagged if its
13734 declaration includes a record extension.
13735 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
13736 node, even if the subunit has errors. This avoids malfunction by
13737 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
13738 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
13739 generation of obsolescent messages for with statements (cannot do
13740 this too early, or we cannot implement avoiding the messages in the
13741 case of obsolescent units withing obsolescent units).
13742 (Install_Siblings): If the with_clause is on a remote descendant of
13743 an ancestor of the current compilation unit, find whether there is
13744 a sibling child unit that is immediately visible.
13745 (Remove_Private_With_Clauses): New procedure, invoked after completing
13746 the analysis of the private part of a nested package, to remove from
13747 visibility the private with_clauses of the enclosing package
13749 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
13750 now centralized in Generate_Reference.
13751 (Install_Limited_Context_Clauses): Remove superfluous error
13752 message associated with unlimited view visible through use
13753 and renamings. In addition, at the point in which the error
13754 is reported, we add the backslash to the text of the error
13755 to ensure that it is reported as a single error message.
13756 Use new // insertion for some continuation messages
13757 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
13758 to create implicit with_clause for parent unit mentioned in original
13759 limited_with_clause.
13760 (Install_Limited_With_Unit): Set entity of parent identifiers if the
13761 unit is a child unit. For ASIS queries.
13762 (Analyze_Subunit): If the subunit appears within a child unit, make all
13763 ancestor child units directly visible again.

13778 a formal object declaration with an access definition or a subtype mark
13779 with a null exclusion.
13780 (P_Generic_Association): Handle association with box, and others_choice
13781 with box, to support Ada 2005 partially parametrized formal packages.
13783 2006-10-31 Robert Dewar <dewar@adacore.com>
13784 Javier Miranda <miranda@adacore.com>
13786 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
13787 (P_Type_Declaration): Remove barrier against the reserved word "limited"
13788 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
13789 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
13790 private extensions.
13791 (P_Type_Declaration): Add the new actual Abstract_Present to every call
13792 to P_Interface_Type_Definition.

13794 if the reserved word abstract has been previously found.
13795 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
13796 object renaming declaration with an access definition or subtype mark
13797 with a possible null exclusion.

13816 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
13819 2006-10-31 Vincent Celier <celier@adacore.com>
13821 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
13822 on VMS, change "__" to '.' before checking the name.
13823 (Record_Ada_Source): Always add the source file name in the list of
13824 of sources, even if it is not the first time, as it is for another
13826 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
13827 dot, instead of replacing only the first '_'.
13829 * prj-part.adb (Parse): Convert project file path to canonical form
13831 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
13832 extended, the project id of the project extending it is recorded in its
13833 data, even when it has already been processed as an imported project.
13835 2006-10-31 Robert Dewar <dewar@adacore.com>
13837 * repinfo.adb (List_Entities): Don't list entities from renaming
13840 2006-10-31 Arnaud Charlet <charlet@adacore.com>
13841 Robert Dewar <dewar@adacore.com>
13843 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
13844 only a restriction warning is active for the given restriction. This is
13845 desirable because we do not want to modify code in the case where only
13847 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
13848 causes overriding of real restrictions.
13849 Take advantage of new No_Restrictions constant.
13851 * raise.h: (__gnat_set_globals): Change profile.
13853 2006-10-31 Arnaud Charlet <charlet@adacore.com>
13855 * rtsfind.adb: Remove s-polint from comment as it exists no more.
13858 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
13859 Move all the entities in obsolete package System.PolyORB_Interface to
13860 System.Partition_Interface.

13875 Javier Miranda <miranda@adacore.com>
13876 Gary Dismukes <dismukes@adacore.com>
13878 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
13879 properly an attempt to apply Unchecked_Access to a protected operation.
13880 (OK_Self_Reference): New subprogram to check the legality of an access
13881 attribute whose prefix is the type of an enclosing aggregate.
13882 Generalizes previous mechanism to handle attribute references nested
13883 arbitrarily deep within the aggregate.
13884 (Analyze_Access_Attribute): An access attribute whose prefix is a type
13885 can appear in an aggregate if this is a default-initialized aggregate
13886 for a self-referential type.
13887 (Resolve_Attribute, case Access): Ditto.
13888 Add support for new implementation defined attribute Stub_Type.
13889 (Eval_Attribute, case Attribute_Stub_Type): New case.
13890 (Analyze_Attribute, case Attribute_Stub_Type): New case.
13891 (Stream_Attribute_Available): Implement using new subprogram from

13893 Has_Specified_Stream_Attribute flag.
13894 Disallow Storage_Size and Storage_Pool for access to subprogram
13895 (Resolve_Attribute, case 'Access et al): Take into account anonymous
13896 access types of return subtypes in extended return statements. Remove
13897 accessibility checks on anonymous access types when Unchecked_Access is
13899 (Analyze_Attribute): Add support for the use of 'Class to convert
13900 a class-wide interface to a tagged type.
13901 Add support for the attribute Priority.
13902 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
13903 whether the designated type is discriminated with a constrained partial
13904 view and require static matching in that case.
13905 Add local variable Des_Btyp. The Designated_Type
13906 of an access to incomplete subtype is either its non-limited view if
13907 coming from a limited with or its etype if regular incomplete subtype.
13909 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
13910 Fix predicate to identify and allow cases of (expander-generated)
13911 references to tag of designated object of a RACW.
13912 (Validate_Static_Object_Name): In Ada 2005, a formal object is
13913 non-static, and therefore cannot appear as a primary in a preelaborable
13915 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
13916 Has_Read_Write_Attributes.
13917 (Has_Read_Write_Attributes): Reimplement in termes of
13918 Has_Stream_Attribute_Definition.
13919 (Missing_Read_Write_Attributes): When checking component types in a
13920 record, unconditionally call Missing_Read_Write_Attributes recursively
13921 (remove guard checking for Is_Record_Type / Is_Access_Type).
13923 2006-10-31 Robert Dewar <dewar@adacore.com>
13925 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
13926 useless assignments here and conditionalize it on absence of exception
13928 (Analyze_Exception_Handlers): Small code reorganization of error
13929 detection code, for new handling of formal packages.
13931 2006-10-31 Ed Schonberg <schonberg@adacore.com>
13932 Hristian Kirtchev <kirtchev@adacore.com>
13934 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
13935 that has been constant-folded, preserve information of original tree,
13937 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
13938 generated private extension declaration if the formal derived type is
13939 synchronized. Carry synchronized present over to the generated private
13941 (Validate_Derived_Type_Instance): Ensure that the actual of a
13942 synchronized formal derived type is a synchronized tagged type.
13943 (Instantiate_Formal_Package): When creating the instantiation used to
13944 validate the actual package of a formal declared without a box, check
13945 whether the formal itself depends on a prior actual.
13946 (Instantiate_Formal_Subprogram): Create new entities for the defining
13947 identifiers of the formals in the renaming declaration, for ASIS use.
13948 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
13949 a renaming declaration or a subtype declaration for an actual in an
13950 instance, capture location information of declaration in generic, for
13952 (Instantiate_Formal_Package): Add comments on needed additional tests.
13953 AI-317 (partial parametrization) is fully implemented.
13954 (Validate_Private_Type_Instance): Add check for actual which
13955 must have preelaborable initialization
13956 Use new // insertion for some continuation messages
13957 (Analyze_Formal_Object_Declaration): Change usage of Expression to
13958 Default_Expression. Add type retrieval when the declaration has an
13959 access definition. Update premature usage of incomplete type check.
13960 (Check_Access_Definition): New subsidiary routine. Check whether the
13961 current compilation version is Ada 05 and the supplied node has an
13963 (Instantiate object): Alphabetize local variables. Handle the creation
13964 of new renaming declarations with respect to the kind of definition
13965 used - either an access definition or a subtype mark. Guard against
13966 unnecessary error message in the context of anonymous access types after
13967 they have been resolved. Add check for required null exclusion in a
13968 formal object declaration.
13969 (Switch_View): A private subtype of a non-private type needs to be
13970 switched (the base type can have been switched without its private
13971 dependents because of the last branch of Check_Private_View.
13972 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
13974 (Instantiate_Type): Emit an error message whenever a class-wide type of
13975 a tagged incomplete type is used as a generic actual.
13976 (Find_Actual_Type): Extend routine to handle a component type in a child
13977 unit that is imported from a formal package in a parent.
13978 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
13979 agree on constrainedness, rather than checking against ultimate ancestor
13980 (Instantiate_Subprogram_Body): Create a cross-reference link to the
13981 generic body, for navigation purposes.
13983 2006-10-31 Robert Dewar <dewar@adacore.com>
13984 Thomas Quinot <quinot@adacore.com>
13986 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
13988 (New_Stream_Subprogram): When processing an attribute definition clause
13989 for a stream-oriented subprogram, record an entity node occurring at
13990 the point of clause to use for checking the visibility of the clause,
13991 as defined by 8.3(23) as amended by AI-195.
13992 (New_Stream_Subprogram): New procedure, factoring behaviour from both
13993 New_Stream_Function and New_Stream_Procedure.
13994 (New_Stream_Function, New_Stream_Procedure): Removed.
13995 (Analyze_Attribute_Definition_Clause, case Address): Check new
13996 Alignment_Check check

13999 Javier Miranda <miranda@adacore.com>
14000 Robert Dewar <dewar@adacore.com>
14002 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
14003 generate the same errors compiling under -gnatc.
14004 (Try_Object_Operation): If no candidate interpretation succeeds, but
14005 there is at least one primitive operation with the right name, report
14006 error in call rather than on a malformed selected component.
14007 (Analyze_Selected_Component): If the prefix is an incomplete type from
14008 a limited view, and the full view is available, use the full view to
14009 determine whether this is a prefixed call to a primitive operation.
14010 (Operator_Check): Verify that a candidate interpretation is a binary
14011 operation before checking the type of its second formal.
14012 (Analyze_Call): Add additional warnings for function call contexts not
14014 (Analyze_Allocator): Move the check for "initialization not allowed for
14015 limited types" after analyzing the expression. This is necessary,
14016 because OK_For_Limited_Init looks at the structure of the expression.
14017 Before analysis, we don't necessarily know what sort of expression it
14018 is. For example, we don't know whether F(X) is a function call or an
14019 indexed component; the former is legal in Ada 2005; the latter is not.
14020 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
14021 were missing. We also didn't handle qualified expressions. Now also
14022 allow function calls. Use new common routine OK_For_Limited_Init.
14023 (Analyze_Type_Conversion): Do not perform some legality checks in an
14024 instance, because the error message will be redundant or spurious.
14025 (Analyze_Overloaded_Selected_Component): Do not do style check when
14026 setting an entity, since we do not know it is the right entity yet.
14027 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
14028 (Analyze_Overloaded_Selected_Component): Same change
14029 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
14030 since regular incomplete subtypes are transformed into corresponding
14031 subtypes of their full views.
14032 (Complete_Object_Operation): Treat name of transformed subprogram call
14033 as coming from source, for browsing purposes.
14034 (Try_Primitive_Operation): If formal is an access parameter, compare
14035 with base type of object to determine whether it is a primitive
14037 (Operator_Check): If no interpretation of the operator matches, check
14038 whether a use clause on any candidate might make the operation legal.
14039 (Try_Class_Wide_Operation): Check whether the first parameter is an
14040 access type whose designated type is class-wide.

14047 warn on infinite loops.
14048 Add \\ to some continuation messages
14049 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
14050 (Process_Bounds): If the bounds are integer literals that result from
14051 constant-folding, and they carry a user-defined type, preserve that type
14052 rather than treating this as an integer range.
14053 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
14054 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
14055 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
14056 left hand side of assignment.
14057 (Analyze_Assignment): Add suport to manage assigments to the attribute
14058 priority of a protected object.
14059 (Check_Possible_Current_Value_Condition): Allow fully qualified names
14060 not just identifiers.
14061 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
14062 or AND THEN for possible tracking.
14063 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
14064 case of while loops so we can track values in the loop body.

14067 Hristian Kirtchev <kirtchev@adacore.com>
14068 Bob Duff <duff@adacore.com>
14070 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
14071 procedure cannot be a protected operation (it is a basic_declaration,
14072 not a subprogram_declaration).
14073 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
14074 Subp. Add logic for entry processing.
14075 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
14076 Determine whether an entry or subprogram of a protected or task type
14077 override an inherited primitive of an implemented interface.
14078 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
14079 Update the actual used in calls to Check_Overriding_Indicator.
14080 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
14081 generate the proper reference to the parent unit, for cross-reference.
14082 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
14084 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
14085 (Add_Extra_Formal): Revise procedure to allow passing in associated
14086 entity, scope, and name suffix, and handle setting of the new
14087 Extra_Formals field.
14088 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
14089 pass new parameters. Add support for adding the new extra access formal
14090 for functions whose calls are treated as build-in-place.
14091 (Analyze_A_Return_Statement): Correct casing in error message.
14092 Move Pop_Scope to after Analyze_Function_Return, because an extended
14093 return statement really is a full-fledged scope. Otherwise, visibility
14094 doesn't work right. Correct use of "\" for continuation messages.
14095 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
14096 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
14097 the node doesn't get properly marked as analyzed.
14098 (Analyze_Subprogram_Body): If subprogram is a function that returns
14099 an anonymous access type that denotes a task, build a Master Entity
14101 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
14102 proper usage of null exclusion in a result definition.
14103 (Process_Formals): Code cleanup and new error message.

14109 base type is an access subtype. This case arrises with null exclusions.
14110 (New_Overloaded_Entity): Do not remove the overriden entity from the
14111 homonym chain if it corresponds with an abstract interface primitive.
14112 (Process_Formals): Replace membership test agains Incomplete_Kind with a
14113 call to the synthesized predicate Is_Incomplete_Type.
14114 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
14116 (Analyze_Subprogram_Declaration): Check that abstract interface
14117 primitives are abstract or null.
14118 (Analyze_Subprogram_Specification): Remove previous check for abstract
14119 interfaces because it was not complete.
14120 (Has_Interface_Formals): Removed.

14125 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
14126 of Analyze_Package_Body, to create Itype references for anonymous
14127 access types created in the package declaration, whose designated types
14128 may have only a limited view.
14129 (Analyze_Package_Specification): For the private part of a nested
14130 package, install private_with_clauses of enclosing compilation unit if
14131 we are in its visible part.
14132 (Declare_Inherited_Private_Subprograms): Complete barrier
14133 to ensure that the primitive operation has an alias to some parent
14134 primitive. This is now required because, after the changes done for the
14135 implementation of abstract interfaces, the contents of the list of
14136 primitives has entities whose alias attribute references entities of
14137 such list of primitives.
14138 (Analyze_Package_Specification): Simplify code that handles parent units
14139 of instances and formal packages.
14140 (Uninstall_Declarations): Check the convention consistency among
14141 primitive overriding operations of a tagged record type.

14155 as potentially use-visible.
14156 (Find_Type): Handle the case of an attribute reference for
14157 implementation defined attribute Stub_Type (simply let the analysis of
14158 the attribute reference rewrite it).
14159 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
14160 type that appears in a Use_Type clause.
14161 (Analyze_Object_Renaming): Add support for renaming of the Priority

14166 (Analyze_Object_Renaming): Introduce checks for required null exclusion
14167 in a formal object declaration or in a subtype declaration.
14168 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
14169 (Check_Null_Exclusion): New local routine to
14170 Analyze_Subprogram_Renaming. Check whether the formals and return
14171 profile of a renamed subprogram have required null exclusions when
14172 their counterparts of the renaming already impose them.
14173 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
14174 Determine whether an entity is inside a generic scope.
14175 (In_Open_Scope): First pass of documentation update.
14176 (Find_Expanded_Name): Add support for shadow entities associated with
14177 limited withed packages. This is required to handle nested packages.
14178 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
14179 that makes a renaming of a limited withed package illegal.
14181 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
14182 Ed Schonberg <schonberg@adacore.com>
14184 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
14185 Check_Overriding_Indicator.
14186 (Analyze_Task_Definition): Ditto.
14187 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
14188 (Check_Overriding_Indicator): To find overridden interface operation,
14189 examine only homonyms that have an explicit subprogram declaration, not
14190 inherited operations created by an unrelated type derivation.
14191 (Check_Overriding_Indicator): When checking for the presence of "null"
14192 in a procedure, ensure that the queried node is a procedure
14194 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
14195 type when the formal is an access to variable.
14196 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
14197 (Analyze_Task_Type): Same addition
14198 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
14199 provide navigation capabilities for entries.

14206 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
14207 inherited from an interface ancestor by another interface in the
14208 context of an instance as 'late'.
14209 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
14210 of a call to a function that dispatches on access result.
14211 (Check_Dispatching_Operation): In case of late overriding of a primitive
14212 that covers abstract interface subprograms we register it in all the
14213 secondary dispatch tables associated with abstract interfaces.
14214 (Check_Dispatching_Call): Add check that a dispatching call is not made
14215 to a function with a controlling result of a limited type. This is a
14216 current implementation restriction.
14217 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
14218 (Check_Dispatching_Operation): Do no emit a warning if the controlling
14219 argument is an interface type that is a generic formal.
14220 (Is_Interface_Subprogram): Removed.
14221 (Check_Dispatching_Operation): If the subprogram is not a dispatching
14222 operation, check the formals to handle the case in which it is
14223 associated with an abstract interface type.

14240 Hristian Kirtchev <kirtchev@adacore.com>
14241 Javier Miranda <miranda@adacore.com>
14243 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
14244 subprogram type to provide better diagnostics in case of ambiguity.
14245 (Covers): Handle coverage of formal and actual anonymous access types in
14246 the context of generic instantiation.
14247 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
14248 abstract interface types; this is required to handle concurrent types
14249 with discriminants and abstract interface types.

14263 Add missing continuation marks in error msgs
14264 (Unqualify): New function for removing zero or more levels of
14265 qualification from an expression. There are numerous places where this
14266 ought to be used, but we currently only deal properly with zero or one
14268 (In_Instance); The analysis of the actuals in the instantiation of a
14269 child unit is not within an instantiation, even though the parent
14270 instance is on the scope stack.

14273 (Check_Obsolescent): Removed
14274 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

14292 (Has_Compatible_Alignment): New function
14293 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
14294 objects to handle the Ada 2005 case, where aliasedness no longer implies

14352 (N_Extended_Return_Statement): New node for extended_return_statement
14354 (N_Return_Object_Declaration): New node for part of

14380 N_Extended_Return_Statement. Alphabetize the cases.
14381 Add cases for new nodes N_Extended_Return_Statement and
14382 N_Return_Object_Declaration. The code is not yet written.

14436 2006-10-31 Olivier Hainque <hainque@adacore.com>
14438 * s-stchop.ads: make this unit preelaborate. This is desirable in

14440 is itself preelaborate.
14442 * s-stchop-vxworks.adb (Set_Stack_Info, Task_Descriptor type): Add
14443 Td_Events component.

14528 * a-rttiev.ads, a-rttiev.adb:
14529 This is a significant redesign primarily for the sake of automatic
14530 timer task termination but also to fix a design flaw.
14531 Therefore we are now using an RTS lock, instead of a protected
14532 object, to provide mutual exclusion to the queue of pending events
14533 and the type Timing_Event is no longer a protected type.

15381 other basic tools. The full version that includes the Ada 2005 stuff
15382 is in separate files a-except-2005.ads/adb. The reason is that we do
15383 not want to cause bootstrap problems with compilers not recognizing

15705 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
15706 Remove 0-9 as debug flag character possibilities
15707 -d is now controlling the primary stack size when its value is a
15708 positive. Also add checks against invalid values, and support for kb,
15709 mb. Ditto for -D switch.

15712 Serguei Rybin <rybin@adacore.com>
15714 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
15715 save/restore routines.
15716 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

15718 Since we are changing the tree format anyway, also get rid of the
15719 junk obsolete Immediate_Errors flag.
15720 (Tree_Read): Change the way of reading Tree_Version_String - now we
15721 read the version string from the tree even if its length is not the
15722 same as the length of the version string computed from Gnatvsn.
15723 (Search_Directory_Present): New Boolean flag for the compiler.
15724 Define Tree_Version_String as a dynamic string.

15749 (Is_Limited_Type): A type whose ancestor is an interface is limited if
15750 explicitly declared limited.

15752 entities. Only used for component marked Is_Tag. If present it stores
15753 the Offset_To_Top function used to provide this value in tagged types
15754 whose ancestor has discriminants.
15756 * exp_ch2.adb: Update status of new Is_Known_Null flag
15758 * sem_ch7.adb: Maintain status of new Is_Known_Null flag

15781 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
15782 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
15783 does not exist in the Ada RM.
15784 (Compatible_Int_Bounds): Determine whether two integer range bounds
15785 are of equal length and have the same start and end values.
15786 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
15787 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
15788 aggregate when it is part of an object declaration.
15789 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
15790 constrains discriminants of its parent, add explicitly the discriminant
15791 constraints of the ancestor by retrieving them from the
15792 stored_constraint of the parent.
15794 2006-02-13 Robert Dewar <dewar@adacore.com>
15796 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
15797 attribute Mechanism_Code is applied to renamed subprogram, modify
15798 prefix to point to base subprogram.
15799 Max/Min attributes now violate Restriction No_Implicit_Conditionals
15801 * sinfo.ads: Document that Mechanism_Code cannot be applied to
15802 renamed subprograms so that the front-end must replace the prefix

15806 Gary Dismukes <dismukes@adacore.com>
15808 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
15809 availability of RE_Interface_Tag.
15810 (Build_Initialization_Call): Fix wrong access to the discriminant value.
15811 (Freeze_Record_Type): Do not generate the tables associated with
15812 timed and conditional dispatching calls through synchronized
15813 interfaces if compiling under No_Dispatching_Calls restriction.
15814 When compiling for Ada 2005, for a nonabstract
15815 type with a null extension, call Make_Controlling_Function_Wrappers
15816 and insert the wrapper function declarations and bodies (the latter
15817 being appended as freeze actions).
15818 (Predefined_Primitive_Bodies): Do not generate the bodies of the
15819 predefined primitives associated with timed and conditional
15820 dispatching calls through synchronized interfaces if we are
15821 compiling under No_Dispatching_Calls.
15822 (Build_Init_Procedure): Use RTE_Available to check if a run-time
15823 service is available before generating a call.
15824 (Make_Controlling_Function_Wrappers): New procedure.
15825 (Expand_N_Full_Type_Declaration): Create a class-wide master for
15826 access-to-limited-interfaces because they can be used to reference
15827 tasks that implement such limited interface.
15828 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
15829 procedure spec and body of the Offset_To_Top function that is generated
15830 when the parent of a type with discriminants has secondary dispatch
15832 (Init_Secondary_Tags): Handle the case in which the parent of the type
15833 containing secondary dispatch tables has discriminants to generate the
15834 correct arguments to call Set_Offset_To_Top.
15835 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
15837 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
15838 Add Wide_[Wide_]Expanded_Name.
15839 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
15840 the same functionality of Get_Prim_Op_Address but applied to predefined
15841 primitive operations because the pointers to the predefined primitives
15842 are now saved in a separate table.
15843 (Parent_Size): Modified to get access to the separate table of primitive
15844 operations or the parent type.
15845 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
15846 functionality of Set_Prim_Op_Address but applied to predefined primitive
15848 (Set_Signature): New subprogram used to store the signature of a DT.
15849 (Displace): If the Offset_To_Top value is not static then call the
15850 function generated by the expander to get such value; otherwise use
15851 the value stored in the table of interfaces.
15852 (Offset_To_Top): The type of the actual has been changed to Address to
15853 give the correct support to tagged types with discriminants. In this
15854 case this value is stored just immediately after the tag field.
15855 (Set_Offset_To_Top): Two new formals have been added to indicate if the
15856 offset_to_top value is static and hence pass this value to the run-time
15857 to store it in the table of interfaces, or else if this value is dynamic
15858 and then pass to the run-time the address of a function that is
15859 generated by the expander to provide this value for each object of the
15862 * rtsfind.ads (Default_Prin_Op_Count): Removed.
15863 (Default_Prim_Op_Count): New entity

15869 Ed Schonberg <schonberg@adacore.com>
15871 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
15872 Make_Adjust_Call done for a newly-allocated object.
15874 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
15875 in a subprogram are wrapped in a cleanup block, indicate that the
15876 subprogram contains an inner block with an exception handler.
15877 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
15878 Adjust call is for a newly-allocated object. In that case we must not
15879 assume that the finalization list chain pointers are correct (since they
15880 come from a bit-for-bit copy of the original object's pointers) so if
15881 the attach level would otherwise be zero (no change), we set it to 4
15882 instead to cause the pointers to be reset to null.
15884 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
15885 reset chain pointers to null.
15887 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15889 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
15890 string, and the context requires a loop for the assignment (e.g.
15891 because the left-hand side is packed), generate a unique name for the
15892 temporary that holds the string, to prevent spurious name clashes.
15894 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15895 Javier Miranda <miranda@adacore.com>
15896 Robert Dewar <dewar@adacore.com>
15897 Gary Dismukes <dismukes@adacore.com>
15899 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
15900 return unconstrained arrays.
15902 (Expand_Call): An indirect call through an access parameter of a
15903 protected operation is not a protected call.
15904 Add circuit to raise CE in Ada 2005 mode following call
15905 to Raise_Exception.
15906 (Register_DT_Entry): Do nothing if
15907 the run-time does not give support to abstract interfaces.
15908 (Freeze_Subprogram): In case of dispatching operations, do not generate
15909 code to register the operation in the dispatch table if the source
15910 is compiled with No_Dispatching_Calls.
15911 (Register_Predefined_DT_Entry): Generate code that calls the new
15912 run-time subprogram Set_Predefined_Prim_Op_Address instead of
15913 Set_Prim_Op_Address.
15915 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
15916 on array assignments if the right-hand side is a function call that has
15917 been inlined. Check is performed on the assignment in the block.
15918 (Process_Bounds): If bounds and range are overloaded, apply preference
15919 rule for root operations to disambiguate, and diagnose true ambiguity.
15920 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
15921 a tag-indeterminate right-hand side even when Expander_Active is True.
15922 Needed to ensure that dispatching calls to T'Input are allowed and
15923 get the tag of the target class-wide object.
15925 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
15926 an inherited primitive operation that already overrides several
15927 abstract interface primitives. For transitivity, the new entity must
15928 also override all the abstract interface primitives covered by the
15929 inherited overriden primitive.
15930 Emit warning if new entity differs from homograph in same scope only in
15931 that one has an access parameter and the other one has a parameter of
15932 a general access type with the same designated type, at the same
15933 position in the signature.
15934 (Make_Inequality_Operator): Use source locations of parameters and
15935 subtype marks from corresponding equality operator when creating the
15936 tree structure for the implicit declaration of "/=". This does not
15937 change anything in behaviour except that the decoration of the
15938 components of the subtree created for "/=" allows ASIS to get the
15939 string images of the corresponding identifiers.
15940 (Analyze_Return_Statement): Remove '!' in warning message.
15941 (Check_Statement_Sequence): Likewise.
15942 (Analyze_Subprogram_Body): For an access parameter whose designated type
15943 is an incomplete type imported through a limited_with clause, use the
15944 type of the corresponding formal in the body.
15945 (Check_Returns): Implicit return in No_Return procedure now raises
15946 Program_Error with a compile time warning, instead of beging illegal.
15947 (Has_Single_Return): Function returning unconstrained type cannot be
15948 inlined if expression in unique return statement is not an identifier.
15949 (Build_Body_To_Inline): It is possible to inline a function call that
15950 returns an unconstrained type if all return statements in the function
15951 return the same local variable. Subsidiary procedure Has_Single_Return
15952 verifies that the body conforms to this restriction.
15954 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
15955 same type, and one of them is of an anonymous access type, convert
15956 the other operand to it, so that this is a valid binary operation for
15958 (Resolve_Type_Conversion): Handle subtypes of protected types and
15959 task types when accessing to the corresponding record type.
15960 (Resolve_Allocator): Add '\' in 2-line warning message.
15961 Remove '!' in warning message.
15962 (Resolve_Call): Add '\' in 2-line warning message.
15963 (Valid_Conversion): Likewise.
15964 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
15965 resulting type may be an access type with an implicit dereference.
15966 Obtain the proper component from the designated type.
15967 (Make_Call_Into_Operator): Handle properly a call to predefined equality
15968 given by an expanded name with prefix Standard, when the operands are
15969 of an anonymous access type.
15970 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
15971 Explicit_Dereference and Resolve_Selected_Component, to verify that the
15972 prefix of the expression is not of an incomplete type. Allows full
15973 diagnoses of all semantic errors.
15974 (Resolve_Actuals): If the actual is an allocator whose directly
15975 designated type is a class-wide interface we build an anonymous
15976 access type to use it as the type of the allocator. Later, when
15977 the subprogram call is expanded, if the interface has a secondary
15978 dispatch table the expander will add a type conversion to force
15979 the displacement of the pointer.
15980 (Resolve_Call): If a function that returns an unconstrained type is
15981 marked Inlined_Always and inlined, the call will be inlined and does
15982 not require the creation of a transient scope.
15983 (Check_Direct_Boolean_Op): Removed
15984 (Resolve_Comparison_Op): Remove call to above
15985 (Resolve_Equality_Op): Remove call to above
15986 (Resolve_Logical_Op): Inline above, since this is only call.
15987 (Valid_Conversion): Handle properly conversions between arrays of
15988 convertible anonymous access types.
15991 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
15992 the literal in an unchecked conversion, because GCC 4.x needs a static
15993 value for a string bound.
15995 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15996 Hristian Kirtchev <kirtchev@adacore.com>
15998 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
15999 components of the corresponding record, take into account component
16000 definitions that are access definitions.
16001 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
16002 procedure is not considered a dispatching call and will be expanded
16005 2006-02-13 Javier Miranda <miranda@adacore.com>
16007 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
16008 controlling argument of the dispatching call is an abstract interface
16009 class-wide type then we use it directly.
16010 Check No_Dispatching_Calls restriction.
16011 (Default_Prim_Op_Position): Remove the code that looks for the last
16012 entity in the list of aliased subprograms. This code was wrong in
16014 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
16015 when the source is compiled with the No_Dispatching_Calls restriction.
16016 (Init_Predefined_Interface_Primitives): No need to inherit primitives
16017 if we are compiling with restriction No_Dispatching_Calls.
16018 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
16019 subprograms if we are compiling under No_Dispatching_Calls restriction.
16020 (Make_DT): Generate a dispatch table with a single dummy entry if
16021 we are compiling with the No_Dispatching_Calls restriction. In
16022 addition, in this case we don't generate code that calls to the
16023 following run-time subprograms: Set_Type_Kind, Inherit_DT.
16024 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
16025 of this subprogram if compiling with the No_Dispatching_Calls
16027 (Expand_Type_Conversion): Instead of using the actual parameter,
16028 the argument passed as parameter to the conversion function was
16029 erroneously referenced by the expander.
16030 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
16031 Set_Predefined_Primitive_Op_Address and Set_Signature.
16032 (Expand_Dispatching_Call): Generate call to
16033 Get_Predefined_Prim_Op_Address for predefined primitives.
16034 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
16035 predefined primitives.
16036 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
16037 primitives we reserve one dummy entry to ensure that the tag does not
16038 point to some memory that is associated with some other object. In
16039 addition, remove all the old code that generated the assignments
16040 associated with the signature of the dispatch table and replace them
16041 by a call to the new subprogram Set_Signature.
16042 (Set_All_DT_Position): Change the algorithm because now we have a
16043 separate dispatch table associated with predefined primitive operations.
16044 (Expand_Interface_Conversion): In case of non-static offset_to_top
16045 add explicit dereference to get access to the object after the call
16046 to displace the pointer to the object.
16047 (Expand_Interface_Thunk): Modify the generation of the actual used
16048 in the calls to the run-time function Offset_To_Top to fulfil its
16050 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

16054 * exp_dist.adb (Copy_Specification): For access parameters, copy
16055 Null_Exclusion flag, which will have been set for stream subprograms
16058 2006-02-13 Pascal Obry <obry@adacore.com>
16060 * expect.c (__gnat_expect_portable_execvp): New implementation. The
16061 previous implementation was using the C runtime spawnve routine but
16062 the corresponding wait was using directly the Win32 API. This was
16063 causing some times a lock when waiting for an event using
16064 WaitForSingleObject in __gnat_waitpid. This new implementation uses
16065 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
16066 API fixes this problem.
16068 2006-02-13 Robert Dewar <dewar@adacore.com>
16070 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

16078 array reference that is an explicit dereference, mark the converted
16079 (packed) array reference as analyzed to prevent a forthcoming
16080 reanalysis from resetting its type to the original (non-packed) array
16083 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16084 Javier Miranda <miranda@adacore.com>
16085 Eric Botcazou <ebotcazou@adacore.com>
16087 * exp_util.ads, exp_util.adb (Find_Prim_Op,
16088 Is_Predefined_Primitive_Operation): When
16089 searching for the predefined equality operator, verify that operands
16090 have the same type.
16091 (Is_Predefined_Dispatching_Operation): Remove the code that looks
16092 for the last entity in the list of aliased subprograms. This code
16093 was wrong in case of renamings.
16094 (Set_Renamed_Subprogram): New procedure
16095 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
16096 Exp_Type constant computed when entering this subprogram.

16098 (OK_To_Do_Constant_Replacement): New function
16099 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
16100 (Side_Effect_Free): An attribute reference 'Input is not free of
16101 side effect, unlike other attributes that are functions. (from code
16103 (Remove_Side_Effects): Expressions that involve packed arrays or records
16104 are copied at the point of reference, and therefore must be marked as
16105 renamings of objects.
16106 (Is_Predefined_Dispatching_Operation): Return false if the operation is
16107 not a dispatching operation.
16110 (Remove_Side_Effects): Lift enclosing type conversion nodes for
16111 elementary types in all cases.
16113 2006-02-13 Javier Miranda <miranda@adacore.com>

16116 task types when accessing to the corresponding record type.
16117 Remove '!' in warning message.
16119 2006-02-13 Olivier Hainque <hainque@adacore.com>
16121 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
16122 to avoid useless and space inefficient overalignments on targets where
16123 Max_Alignment is larger than 16.
16125 2006-02-13 Pascal Obry <obry@adacore.com>
16127 * g-catiio.adb (Sec_Number): New type used to compute the number of
16128 seconds since 1-1-1970.
16129 (Image) [Natural]: The parameter was an Integer, as we can't deal with
16130 negative numbers (years, months...) it is better to have a Natural here.
16132 (Image) [Number]: Change parameter from Long_Integer to Number.
16133 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
16134 overflow for dates past year 2038.
16136 2006-02-13 Matthew Heaney <heaney@adacore.com>
16138 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
16141 2006-02-13 Arnaud Charlet <charlet@adacore.com>
16143 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
16145 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
16146 finalization can occur normally.
16148 2006-02-13 Vincent Celier <celier@adacore.com>
16150 * gnatcmd.adb (Rules_Switches): New table
16151 (Add_To_Rules_Switches): New procedure
16152 (GNATCmd): For command CHECK, put all options following "-rules" in the
16153 Rules_Switches table. Append these -rules switches after the -cargs
16156 2006-02-13 Robert Dewar <dewar@adacore.com>
16158 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
16159 These two cases were generating incorrect output, and if this unit
16160 was built with checks on, generated a discriminant mismatch constraint
16163 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16164 Robert Dewar <dewar@adacore.com>
16166 * lib-xref.adb (Get_Type_Reference): For a private type whose full
16167 view is an array type, indicate the component type as well, for
16168 navigation purposes.
16169 (Generate_Reference): Don't consider array ref on LHS to be a case
16170 of violating pragma Unreferenced.
16171 Do not give Ada 2005 warning except on real reference.
16173 2006-02-13 Vincent Celier <celier@adacore.com>
16175 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
16176 main source, add switch -mdebug-main=_ada_ so that the executable can
16177 be debugged by the standard VMS debugger.
16178 (Gnatmake): Set No_Main_Subprogram to True when there is no main
16179 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
16180 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
16181 of the last source, as the binding and linking phases are never
16183 Set all executable obsolete when rebuilding a library.
16185 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
16188 2006-02-13 Javier Miranda <miranda@adacore.com>
16191 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
16192 code to improve the error message reported when the program has
16193 declarations of abstract interface types and it is not compiled with
16194 the -gnat05 switch.
16195 (P_Access_Definition): Reorganize the code to improve the error
16196 message reported when the new Ada 2005 syntax for anonymous
16197 access types is used and the program is not compiled with the

16214 the standard naming data.
16216 2006-02-13 Vincent Celier <celier@adacore.com>
16218 * prj.ads (Error_Warning): New enumeration type
16220 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
16221 unknown, use the location of the project to report the error.
16222 (When_No_Sources): New global variable
16223 (Report_No_Ada_Sources): New procedure
16224 (Check): New parameter When_No_Sources. Set value of global variable
16226 (Find_Sources): Call Report_No_Ada_Sources when appropriate
16227 (Get_Sources_From_File): Ditto
16228 (Warn_If_Not_Sources): Better warning messages indicating the unit name
16231 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
16232 Call Prj.Proc.Process with parameter When_No_Sources.
16234 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
16235 Call Recursive_Check with parameter When_No_Sources.
16236 (Recursive_Check): New parameter When_No_Sources. Call itself and
16237 Prj.Nmsc.Check with parameter When_No_Sources.
16238 (Process): New parameter When_No_Sources. Call Check with parameter
16240 (Copy_Package_Declarations): New procedure to copy renamed parameters
16241 and setting the location of the declared attributes to the location
16242 of the renamed package.

16250 When removing nodes (attributes Source_Dirs, Source_Files,
16251 Source_List_File and package Naming), save the comments and attach the
16252 saved comments to the newly created nodes.
16253 Do not add a with clause for the naming package if one already exists.

16261 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
16262 aliased entities to look for the overriden abstract interface
16264 (Is_Interface_Subprogram): Complete documentation.
16265 (Check_Dispatching_Operation): Do not generate code to register the
16266 operation in the dispatch table if the source is compiled with
16267 restriction No_Dispatching_Calls.

16269 No_Return procedure with procedure that is not No_Return
16270 (Check_Dispatching_Call): Suppress the check for an abstract operation
16271 when the original node of an actual is a tag-indeterminate attribute
16272 call, since the attribute, which must be 'Input, can never be abstract.
16273 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
16274 call to the Input attribute (even when rewritten).
16275 (Propagate_Tag): Augment comment to indicate the possibility of a call
16276 to an Input attribute.
16278 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
16279 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
16281 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
16282 No_Wide_Characters is no longer partition-wide
16283 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
16286 2006-02-13 Douglas Rupp <rupp@adacore.com>
16288 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
16290 2006-02-13 Javier Miranda <miranda@adacore.com>
16292 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
16293 handles default-initialized components to keep separate the management
16294 of this feature but also avoid the unrequired resolution and
16295 expansion of components that do not have partially initialized
16297 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
16298 (Check_Bounds): Likewise.
16299 (Check_Length): Likewise.
16301 2006-02-13 Javier Miranda <miranda@adacore.com>
16302 Ed Schonberg <schonberg@adacore.com>
16304 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
16305 abstract interface type call analyze_and_resolve to expand the type
16306 conversion into the corresponding displacement of the
16307 reference to the base of the object.
16308 (Eval_Attribute, case Width): For systems where IEEE extended precision
16309 is supported, the maximum exponent occupies 4 decimal digits.
16310 (Accessibility_Message): Add '\' in 2-line warning message.
16311 (Resolve_Attribute): Likewise.
16312 (case Attribute_Access): Significantly revise checks
16313 for illegal access-to-subprogram Access attributes to properly enforce
16314 the rules of 3.10.2(32/2).
16315 Diagnose use of current instance with an illegal attribute.
16317 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
16319 (Enclosing_Generic_Unit): New function to return a node's innermost
16320 enclosing generic declaration node.
16321 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
16322 (Type_Access_Level): The accessibility level of anonymous acccess types
16323 associated with discriminants is that of the current instance of the
16324 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
16325 (Compile_Time_Constraint_Error): Handle case of conditional expression.
16326 (Kill_Current_Values_For_Entity): New function
16327 (Enter_Name): Change formal type to Entity_Id
16329 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
16330 Ed Schonberg <schonberg@adacore.com>
16331 Gary Dismukes <dismukes@adacore.com>
16333 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
16334 Analyze_Compilation_Unit.
16335 Detect and warn on redundant with clauses detected in a package spec
16336 and/or body when -gnatwr is used.

16338 (Install_Context_Items): Don't analyze config pragmas here
16339 (Install_Limited_Withed_Unit): Set limited entity of package in
16340 with_clause so that cross-reference information or warning messages on
16341 unused packages can be properly generated
16342 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
16343 has Error_Posted set. Prevent infinite loops in illegal programs.
16344 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
16345 to the point of the error test requiring the current unit to be private.
16346 This ensures that private with clauses are not exempted from the basic
16347 checking for being a descendant of the same library unit parent as a
16348 withed private descendant unit.
16349 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
16350 handle private with clauses properly, as well as to account for cases
16351 where the withed unit is a public descendant of a private ancestor
16352 (in which case the current unit must be a descendant of the private
16353 ancestor's parent). The spec comments were updated accordingly. Also,
16354 the old error message in this subprogram was replaced with error
16355 messages that mirror the errors tested and reported by
16356 Check_Private_Child_Unit.
16357 Parameter and variable names improved for readability.
16358 (Install_Limited_Context_Clauses): Remove test for a withed unit being
16359 private as the precondition for calling
16360 Check_Private_Limited_Withed_Unit since that subprogram has been
16361 revised to test public units as well as private units.

16368 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
16369 that Scope_Stack.First = 1.
16370 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
16371 were not always properly handled previously.
16372 (Formal_Entity): Complete rewrite, to handle properly some complex case
16373 with multiple levels of parametrization by formal packages.
16374 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
16375 to the corresponding derived type declaration for proper semantics.
16377 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
16378 (Check_Component): Enforce restriction on components of
16379 unchecked_unions: a component in a variant cannot contain tasks or
16381 (Unchecked_Union): Allow nested variants and multiple discriminants, to
16383 Add pragma Ada_2005 (synonym for Ada_05)
16384 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
16385 were not always properly handled previously.
16386 Document that pragma Propagate_Exceptions has no effect
16387 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
16388 (Set_Convention_From_Pragma): Check that if a convention is
16389 specified for a dispatching operation, then it must be
16390 consistent with the existing convention for the operation.
16391 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
16392 longer required to specify an vtable-ptr component in the record. For
16393 compatibility reasons we leave the support for the previous definition.
16394 (Analyze_Pragma, case No_Return): Allow multiple arguments
16396 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
16397 non-overrideen inherited operation with a controlling result as
16398 illegal only its implicit declaration comes from the derived type
16399 declaration of its result's type.
16400 (Check_Possible_Deferred_Completion): Relocate the object definition
16401 node of the subtype indication of a deferred constant completion rather
16402 than directly analyzing it. The analysis of the generated subtype will
16403 correctly decorate the GNAT tree.
16404 (Record_Type_Declaration): Check whether this is a declaration for a
16405 limited derived record before analyzing components.
16406 (Analyze_Component_Declaration): Diagnose record types not explicitly
16407 declared limited when a component has a limited type.
16408 (Build_Derived_Record_Type): Code reorganization to check if some of
16409 the inherited subprograms of a tagged type cover interface primitives.
16410 This check was missing in case of a full-type associated with a private
16412 (Constant_Redeclaration): Check that the subtypes of the partial and the
16413 full view of a constrained deferred constant statically match.
16414 (Mentions_T): A reference to the current type in an anonymous access
16415 component declaration must be an entity name.
16416 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
16417 class_wide type to refer to full type, not to the incomplete one.
16418 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
16419 available. Required to give support to the certified run-time.
16420 (Analyze_Component_Declaration): In case of anonymous access components
16421 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
16422 (Process_Discriminants): For an access discriminant, use the
16423 discriminant specification as the associated_node_for_itype, to
16424 simplify accessibility checks.

16427 Javier Miranda <miranda@adacore.com>
16429 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
16430 abstract interpretations on an operator, remove interpretations that
16431 yield Address or a type derived from it, if one of the operands is an
16433 (Try_Object_Operation.Try_Primitive_Operation,
16434 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
16435 location when creating the new reference to a primitive or class-wide
16436 operation as a part of rewriting a subprogram call.
16437 (Try_Primitive_Operations): If context requires a function, collect all
16438 interpretations after the first match, because there may be primitive
16439 operations of the same type with the same profile and different return
16440 types. From code reading.
16441 (Try_Primitive_Operation): Use the node kind to choose the proper
16442 operation when a function and a procedure have the same parameter
16444 (Complete_Object_Operation): If formal is an access parameter and prefix
16445 is an object, rewrite as an Access reference, to match signature of
16446 primitive operation.
16447 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
16448 by an expanded name with prefix Standard, when the operands are of an
16449 anonymous access type.
16450 (Remove_Abstract_Operations): If the operation is abstract because it is
16451 inherited by a user-defined type derived from Address, remove it as
16452 well from the set of candidate interpretations of an overloaded node.
16453 (Analyze_Membership_Op): Membership test not applicable to cpp-class
16456 2006-02-13 Bob Duff <duff@adacore.com>
16458 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
16459 redundant use clauses.
16460 In particular, if the scope of two use clauses overlaps, but one is not
16461 entirely included in the other, we should not warn. This can happen
16462 with nested packages.
16463 (Analyze_Subprogram_Renaming): Protect the compiler against previously
16464 reported errors. The bug was reported when the compiler was built
16465 with assertions enabled.
16466 (Find_Type): If the node is a 'Class reference and the prefix is a
16467 synchronized type without a corresponding record, return the type
16470 2006-02-13 Javier Miranda <miranda@adacore.com>
16472 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
16473 if this is the full-declaration associated with a private declaration
16474 that implement interfaces, then the private type declaration must be
16476 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
16477 as aliased. The use of the 'access attribute is not available for such
16478 object (for this purpose the object should be explicitly marked as
16479 aliased, but being an anonymous type this is not possible).
16481 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16482 Robert Dewar <dewar@adacore.com>
16484 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
16485 compilation unit is an elaboration scope.
16486 (Add_Task_Proc): Add '\' in 2-line warning message.
16487 (Activate_All_Desirable): Deal with case of unit with'ed by parent
16489 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16490 Javier Miranda <miranda@adacore.com>
16492 * sem_type.adb (Write_Overloads): Improve display of candidate
16494 (Add_One_Interp): Do not add to the list of interpretations aliased
16495 entities corresponding with an abstract interface type that is an
16496 immediate ancestor of a tagged type; otherwise we have a dummy
16497 conflict between this entity and the aliased entity.
16498 (Disambiguate): The predefined equality on universal_access is not
16499 usable if there is a user-defined equality with the proper signature,
16500 declared in the same declarative part as the designated type.
16501 (Find_Unique_Type): The universal_access equality operator defined under
16502 AI-230 does not cover pool specific access types.
16503 (Covers): If one of the types is a generic actual subtype, check whether
16504 it matches the partial view of the other type.
16506 2006-02-13 Thomas Quinot <quinot@adacore.com>
16508 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
16509 line. This is necessary to allow In_Extended_Main_Unit to provide
16510 correct results for itypes while writing out expanded source.
16511 (Close_File): No need to update the source_index_table here since it's
16512 now done for each line.
16514 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16515 Robert Dewar <dewar@adacore.com>
16517 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
16518 preserve the source unit where the itype is declared, and prevent a
16520 (Note_Implicit_Run_Time_Call): New procedure
16521 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
16524 * sprint.ads: Document use of $ for implicit run time routine call
16526 2006-02-13 Quentin Ochem <ochem@adacore.com>
16528 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
16531 2006-02-13 Bob Duff <duff@adacore.com>
16533 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
16534 Scan_Unsigned, so we do not scan leading blanks and sign twice.
16535 Integer'Value("- 5") and Integer'Value("-+5") now correctly
16536 raise Constraint_Error.
16538 * s-vallli.adb (Scan_Long_Long_Integer): Call
16539 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
16540 do not scan leading blanks and sign twice.
16541 Integer'Value("- 5") and Integer'Value("-+5") now correctly
16542 raise Constraint_Error.
16544 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
16545 Scan_Long_Long_Unsigned): Split out most of the processing from
16546 Scan_Long_Long_Unsigned out into
16547 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
16548 This prevents scanning leading blanks and sign twice.
16549 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
16552 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
16553 out most of the processing from Scan_Unsigned out into
16554 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
16555 This prevents scanning leading blanks and sign twice.
16557 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
16558 use with Modular'Value attribute.
16559 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
16562 2006-02-13 Robert Dewar <dewar@adacore.com>
16564 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
16566 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>

16569 (PPC VxWorks): Likewise.
16570 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
16571 (forced_callee): Make non-inlinable and non-pure.
16572 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

16687 ({declaraction},Delete_Binder_Generated_Files,{initialization}): Change
16688 Ada bind file prefix on VMS from b$ to b__.
16690 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in

16692 (Gnatlink): Call Get_Target_Parameters in mainline.
16693 Initialize standard packages for Targparm.
16694 Change some Hostparm.OpenVMS checks to Targparm.OpenVMS_On_Target.

16714 (../../vxaddr2line): gnatlink with targext.o.
16715 (TOOLS_LIBS): Move targext.o to precede libgnat.
16716 (init.o, initialize.o): Minor clean up in dependencies.

16754 Quentin Ochem <ochem@adacore.com>
16755 Florian Villoing <villoing@adacore.com>
16757 * a-taster.ads, a-taster.adb: New files.
16759 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
16760 link to the version that does nothing. This way the task termination
16761 routine is not executed twice for the environment task when finishing
16762 because of an unhandled exception.
16764 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
16765 handler because of an unhandled exception.
16767 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
16768 System.Tasking.Utilities instead of that in System.Tasking.Stages.
16770 * s-finimp.adb (initialization code): Modify the soft link for the
16771 finalization of the global list instead of Adafinal.
16773 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
16774 non-tasking version of the soft link for task termination. We do
16775 nothing since if we are using the non-tasking version it
16776 means that the task termination functionality is not used.
16777 (Null_Finalize_Global_List): Add this null version for the procedure
16778 in charge of finalizing the global list for controlled objects.
16779 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
16780 instead for handling run-time termination in a more flexible way.
16781 (Adafinal_NT): This new procedure will take care of finalizing the
16782 global list for controlled objects if needed, but no tasking
16785 * s-tarest.adb (Task_Lock): Do not try to lock again the
16786 Global_Task_Lock if we already own it. Otherwise, we get blocked in
16787 some run-time operations.
16788 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
16789 until all nested locks have been released.
16790 (Task_Wrapper): Call the fall-back task termination handler. It
16791 applies to all tasks but the environment task.
16792 (Finalize_Global_Tasks): Add the call for the task termination
16793 procedure for the environment task.
16794 (Task_Wrapper): suppress warnings around declaration of
16795 Secondary_Stack_Address.
16797 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
16798 moved to the Common_ATCB record.
16799 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
16800 Common_ATCB record.
16801 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
16802 Common_ATCB record.
16804 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
16805 Fall_Back_Handler, and Specific_Handler.
16807 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
16808 defined in Ada.Task_Termination, to avoid circular dependencies.
16809 (Termination_Handler): Redefine this type here, alredy defined in
16810 Ada.Task_Termination, for avoiding circular dependencies.
16811 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
16812 for storing task termination handlers. In addition,
16813 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
16814 Common_ATCB because it is used by both the regular and the restricted
16816 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
16817 Common_ATCB because it is used by both the regular and the restricted
16819 (Common_ATCB): Added a dynamic task analyzer field.
16821 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
16822 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
16823 (Task_Wrapper): Call the task termination handler. It applies to all
16824 tasks but the environment task.
16825 (Finalize_Global_Tasks): Call the task termination procedure for the
16826 environment task. The call to Finalize_Global_List is now performed
16827 using the soft links mechanism.
16828 (Task_Wrapper): added dynamic stack analysis.
16830 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
16831 potentially blocking operations has been moved from
16832 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
16833 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
16834 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
16835 this run-time check.
16837 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
16838 of task termination procedure.
16839 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
16840 link for the task termination procedure.
16842 * bindusg.adb: (Bindusg): Added documentation for -u option.
16844 * bindgen.adb (Get_Main_Ada) Added handling of dynamic stack analysis.
16845 (Get_Main_C): Add handling of dynamic stack analysis.
16846 (Gen_Output_File_C): Add external functions for dynamic stack analysis.

16852 * opt.ads: Added flags used by dynamic stack measurement.
16853 (Max_Line_Length): Remove (not used anymore)
16855 * s-io.ads, s-io.adb (Standard_Error): new subprogram
16856 (Standart_Output): new subprogram
16857 (Set_Output): new subprogram
16858 (Put): now uses the value of Current_Out to know if the output has to be
16859 send to stderr or stdout.
16861 * s-stausa.ads: Complete implementation.
16863 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
16865 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
16866 list of Ada 05 files.
16867 (GNAT Library Units): Add AltiVec files.
16869 * g-allein.ads, g-alleve.adb, g-alleve.ads, g-altcon.adb,
16870 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
16871 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
16873 2005-12-09 Nicolas Setton <setton@adacore.com>
16875 * adaint.c (__gnat_locate_regular_file): Return immediately if
16876 file_name is empty.
16878 2005-12-09 Javier Miranda <miranda@adacore.com>
16879 Hristian Kirtchev <kirtchev@adacore.com>
16881 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
16882 to the specification because the frontend generates code that uses this
16884 (Set_Interface_Table): Add missing assertion.
16885 Update documentation describing the run-time structure.
16886 (Displace): New subprogram that displaces the pointer to the object
16887 to reference one of its secondary dispatch tables.
16888 (IW_Membership): Modified to use the new table of interfaces.
16889 (Inherit_TSD): Modified to use the new table of interfaces.
16890 (Register_Interface_Tag): Use the additional formal to fill the
16891 contents of the new table of interfaces.
16892 (Set_Interface_Table): New subprogram that stores in the TSD the
16893 pointer to the table of interfaces.
16894 (Set_Offset_To_Top): Use the additional formal to save copy of
16895 the offset value in the table of interfaces.
16896 Update structure of GNAT Primary and Secondary dispatch table diagram.
16897 Add comment section on GNAT dispatch table prologue.
16898 (Offset_To_Signature): Update the constant value of the Signature field.
16899 (Dispatch_Table): Update comment on hidden fields in the prologue.
16900 (Get_Entry_Index, Get_Prim_Op_Kind, Get_Offset_Index, OSD,
16901 Set_Entry_Index, Set_Offset_Index, Set_Prim_Op_Kind, SSD, TSD): Change
16902 the type of formal parameter T to Tag, introduce additional assertions.
16903 (Get_Num_Prim_Ops, Set_Num_Prim_Ops): Remove an unnecessary type
16905 (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
16907 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
16908 in all the calls to Expand_Interface_Thunk. Instead of referencing the
16909 record component containing the tag of the secondary dispatch table we
16910 have to use the Offset_To_Top run-time function to get this information;
16911 otherwise if the pointer to the base of the object has been displace
16912 we get a wrong value if we use the 'position attribute.
16914 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
16915 all the calls to Expand_Interface_Thunk.
16916 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
16917 interfaces; hence the call to Set_Interface_Table was clearly wrong.
16918 (Collect_All_Interfaces): Modify the internal subprogram Collect to
16919 ensure that the interfaces implemented by the ancestors are placed
16920 at the header of the generated list.
16921 (Expand_Interface_Conversion): Handle the case in which the displacement
16922 associated with the interface conversion is not statically known. In
16923 this case we generate a call to the new run-time subprogram Displace.
16924 (Make_DT): Generate and fill the new table of interfaces.
16925 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
16926 Get_Tagged_Kind and Set_Tagged_Kind.
16927 (Tagged_Kind): New function that determines the tagged kind of a type
16928 with respect to limitedness and concurrency and returns a reference to
16930 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
16931 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
16932 primary dispatch table for a type.

17156 legal within a protected type that implements an interface.
17157 (Collect_Interfaces): Do not add to the list the interfaces that
17158 are implemented by the ancestors.
17159 (Derived_Type_Declaration): If the parent of the full-view is an
17160 interface perform a transformation of the tree to ensure that it has
17161 the same parent than the partial-view. This simplifies the job of the
17162 expander in order to generate the correct object layout, and it is
17163 needed because the list of interfaces of the full-view can be given in
17165 (Process_Full_View): The parent of the full-view does not need to be
17166 a descendant of the parent of the partial view if both parents are

17183 (Process_Full_View): Improve the check for the "no hidden interface"
17184 rule as defined by AI-396.
17186 2005-12-09 Robert Dewar <dewar@adacore.com>

17243 available user-specified stream attributes on limited parameters to
17244 also test the type directly rather than only its underlying type (for
17245 Ada 95) and, in the case of Ada 2005, to check that the user-specified
17246 attributes are visible at the point of the subprogram declaration.
17247 For Ada 2005, the error message is modified to indicate that the
17248 type's stream attributes must be visible (again, only for -gnat05).

17280 types use the corresponding record type. This was not needed before
17281 the implementation of Ada 2005 synchronized types because
17282 concurrent types were never tagged types in Ada 95.

17410 * socket.c: Add extern int h_errno for rtems since networking header
17411 files are not available at this point in a tool bootstrap. Newlib

17528 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for

17687 we are not defining the type.
17688 <E_Record_Type>: Likewise.
17689 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
17690 to get advantage of the new maybe_stabilize_reference interface, to

17693 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
17694 type imported through a limited_with clause, use its non-limited view.
17695 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others

17704 that we are not defining.
17705 (elaborate_expression_1): Do not create constants when creating
17706 variables needed by the debug info: the dwarf2 writer considers that
17707 CONST_DECLs is used only to represent enumeration constants, and emits
17709 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
17710 object with an address clause into an indirect reference, drop the

17725 is provided by the front-end, use that subtype to compute the size of
17726 the deallocated object.

17734 without need to check for the success indication.
17735 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
17736 pass false instead of 0 as the FORCE argument which is a bool.
17737 (Identifier_to_gnu): Remove checks ensuring that an renamed object
17738 attached to a renaming pointer has been properly stabilized, as no such
17739 object is attached otherwise.
17740 (call_to_gnu): Invoke create_var_decl to create the temporary when the
17741 function uses the "target pointer" return mechanism.
17742 Reinstate conversion of the actual to the type of the formal
17743 parameter before any other specific treatment based on the passing

17754 static output of record constructor if all the components are constant.
17755 (gnat_build_constructor): For a record type, sort the list of field
17756 initializers in increasing bit position order.

17758 from a fat or thin pointer type and a constrained object type.
17759 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
17760 types variants, and process special cases of VIEW_CONVERT expressions

17762 CORRESPONDING_VARs associated with CONST_DECls.
17763 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
17764 on the right-hand side.

17771 extracting the object if converting to a type variant.
17772 (create_var_decl): When a variable has an initializer requiring code
17773 generation and we are at the top level, check for a potential violation
17774 of a No_Elaboration_Code restriction.
17775 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN

17918 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
17919 for task component, in the case of a limited aggregate. The enclosed
17920 object declaration will create it earlier. Otherwise, in the case of a
17921 nested aggregate, the object may appear in the wrong scope.
17922 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
17923 (Gen_Assign): If the component being assigned is an array type and the
17924 expression is itself an aggregate, wrap the assignment in a block to
17925 force finalization actions on the temporary created for each row of the
17927 (Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
17928 structures are initialized after all discriminants are set so that
17929 they can be accessed even when their offset is dynamic.

17957 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
17958 and related): For a prefix that is an explicit dereference of an

17960 with an actual subtype so GIGI can make a correct size computation.
17961 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
17962 'Unrestricted_Access, if the designated type is an interface we
17963 add a type conversion to force the displacement of the pointer
17964 to the secondary dispatch table.
17965 Use Universal_Real instead of Long_Long_Float when we need a high
17966 precision float type for the generated code (prevents gratuitous
17967 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
17968 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
17969 'Terminated for task interface class-wide objects. Generate a call to
17970 the predefined dispatching routine used to retrieve the _task_id from
17971 a task corresponding record.

17995 (Expand_N_If_Statement): When killing a dead then-branch in an
17996 if-statement that has elsif_parts, recompute the Current_Value node
17997 for any entity whose value is known from the condition of the first
17999 (Expand_N_Return_Statement): When returning a mutable record, convert
18000 the return value into its actual subtype in order to help the backend
18001 to return the actual size instead of the maximum. This is another
18002 aftermath of not returning mutable records on the sec-stack anymore.
18004 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
18005 handling of error msg for suspicious reverse range iteration.
18006 (Check_Possible_Current_Value_Condition): Move declaration from body to

18031 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we
18032 need a high precision float type for the generated code (prevents
18033 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
18036 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we

18051 attribute of the N_Free_Statement.
18052 Generate itype for classwide designated object in both cases of
18053 user-specified storage pool: specific and class-wide, not only in the
18055 Raise CE when trying to set a not null access type object to null.
18056 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
18057 an explicit loop, because freeze nodes make its position variable.

18294 scope against package Standard. Add comments and a ??? comment.
18295 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
18296 on a child instance parent to test that the parent equals

18317 (Build_Derived_Record_Type): Relax the condition that controls the
18318 execution of the check that verifies that the partial view and

18328 (Process_Full_View): Rename local subprogram Find_Interface_In_
18329 Descendant to Find_Ancestor_Interface to leave the code more clear.
18330 Remove wrong code that avoids the generation of an error message
18331 when the immediate ancestor of the partial view is an interface.
18332 In addition some minor reorganization of the code has been done to
18333 leave it more clear.
18334 (Analyze_Type_Declaration): If type has previous incomplete tagged
18335 partial view, inherit properly its primitive operations.
18336 (Collect_Interfaces): Make public, for analysis of formal

18349 be included in the interface list.
18350 (Access_Definition): If the designated type is an interface that may
18351 contain tasks, create Master_Id for it before analyzing the expression
18352 of the declaration, which may be an allocator.

18363 subprogram declaration.
18364 Change name Is_Package to Is_Package_Or_Generic_Package
18365 (Process_Formals): A non null qualifier on a non null named access
18366 type is not an error, and is a warning only if Redundant_Constructs

18380 Change name Is_Package to Is_Package_Or_Generic_Package
18381 (Preserve_Full_Attributes): For a synchronized type, the corresponding
18382 record is absent in a generic context, which does not indicate a
18385 2005-11-14 Ed Schonberg <schonberg@adacore.com>
18387 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
18388 not try to rewrite a renamed stream attribute, because the operations
18389 on the type may not have been generated.
18390 Handle properly a renaming_as_body generated for a stream operation
18391 whose default is abstract because the object type itself is abstract.
18392 (Find_Type): If the type is incomplete and appears as the prefix of a
18393 'Class reference, it is tagged, and its list of primitive operations
18394 must be initialized properly.
18395 (Chain_Use_Clauses): When chaining the use clauses that appear in the
18396 private declaration of a parent unit, prior to compiling the private
18397 part of a child unit, find on the scope stack the proper parent entity
18398 on which to link the use clause.
18399 (Note_Redundant_Use): Emit a warning when a redundant use clause is
18401 (Analyze_Object_Renaming): An attribute reference is not a legal object
18402 if it is not a function call.

18407 * sem_eval.adb: Implement d.f flag
18408 (Subtype_Statically_Match): A generic actual type has unknown
18409 discriminants when the corresponding actual has a similar partial view.
18410 If the routine is called to validate the signature of an inherited
18411 operation in a child instance, the generic actual matches the full view,

18418 * sem_res.adb (Resolve_Call): Provide a better error message whenever
18419 a procedure call is used as a select statement trigger and is not an
18420 entry renaming or a primitive of a limited interface.
18421 (Valid_Conversion): If the operand has a single interpretation do not
18422 remove address operations.
18423 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
18424 statement to inhibit warning.
18425 (Resolve_Unary_Op): Do not produce a warning when
18426 processing an expression of the form -(A mod B)
18427 Use Universal_Real instead of Long_Long_Float when we need a high
18428 precision float type for the generated code (prevents gratuitous
18429 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
18430 (Resolve_Concatenation_Arg): Improve error message when argument is an
18431 ambiguous call to a function that returns an array.
18432 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
18433 there is an implicit operator in the given scope if we are within an
18434 instance: legality check has been performed on the generic.
18435 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
18436 after resolving operand, to avoid false warnings on overloaded calls.

18439 Javier Miranda <miranda@adacore.com>
18442 * sem_type.adb (Covers): In an inlined body, a composite type matches
18443 a private type whose full view is a composite type.
18444 (Interface_Present_In_Ancestor): Protect the frontend against
18445 previously detected errors to ensure that its compilation
18446 with assertions enabled gives the same output that its
18447 compilation without assertions.
18448 (Interface_Present_In_Ancestor): Add support for private types.
18449 Change name In_Actual to In_Generic_Actual (clean up)
18450 (Disambiguate): New predicate In_Actual, to recognize expressions that
18451 appear in the renaming declaration generated for generic actuals, and
18452 which must be resolved in the outer context.

18466 for a parameterless procedure.
18467 (Enter_Name): Recognize renaming declarations created for private
18468 component of a protected type within protected operations, so that
18469 the source name of the component can be used in the debugger.

19118 entity of a primitive wrapper.
19119 (Write_Entity_Flags): Output the name and value of the
19120 Is_Primitive_Wrapper attribute.
19121 (Write_Field27_Name): Output the name and entity of the field Wrapped_
19123 (Underlying_Type): If we have an incomplete entity that comes from
19124 the limited view then we return the Underlying_Type of its non-limited
19125 view if it is already available.
19126 (Abstract_Interface_Alias): Flag applies to all subrogram kinds,
19127 including operators.
19128 (Write_Field26_Name): Add entry for Overridden_Operation

19132 predefined position in the dispatch table for the primitive operations
19133 used in dispatching selects.
19134 (Init_Predefined_Interface_Primitives): Remove the hardcoded number of
19135 predefined primitive operations and replace it with
19136 Default_Prim_Op_Count.

19138 Make_Disp_Get_Prim_Op_Kind_Spec, Make_Disp_Timed_Select_Spec): Update
19139 the names of the generated primitive operations used in dispatching
19141 (Init_Predefined_Interface_Primitives): No need to inherit primitives in

19145 ancestor interface for the elaboration of abstract interface types.
19146 The dispatch table will be inherited by the object implementing the

19153 the entries associated with predefined primitives of all the secondary
19155 (Build_Anonymous_Access_Type): Removed.
19156 (Expand_Interface_Actuals): With the previous cleanup there is no need
19157 to build an anonymous access type. This allows further cleanup in the
19158 code generated by the expander.
19159 (Expand_Interface_Conversion): If the actual is an access type then
19160 build an internal function to handle the displacement. If the actual
19161 is null this function returns null because no displacement is
19162 required; otherwise performs a type conversion that will be
19163 expanded in the code that returns the value of the displaced actual.
19164 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
19165 conversions that have no effect in the generated code because no
19166 displacement is required. Code cleanup; use local variables to
19167 avoid repeated calls to the subprogram directly_designated_type().

19175 (Build_Task_Image_Function): Change Subtype_Mark to Result_Definition.
19176 (Expand_Subtype_From_Expr): Do not build actual subtype if the
19177 expression is limited.
19178 (Find_Interface_Tag): Add code to handle class-wide types and
19179 entities from the limited-view.
19181 * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
19182 Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,
19183 POK_Protected_Entry, POK_Protected_Function, POK_Protected_Procedure,

19207 Move with clauses outside Warnings Off now that dependent units are
19209 (Initialize): Call Interrupt_Managemeent.Initialize to ensure proper
19210 initialization of this unit.
19211 (Specific): Add new procedures Initialize and Delete so that this
19212 package can be used for VxWorks 5.x and 6.x
19213 (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
19214 differences between VxWorks 5.x and 6.x
19215 Minor reformatting.
19216 (Timed_Delay): Remove calls to Defer/Undefer_Abort, now performed by

19236 * adaint.c: The wait.h header is not located in the sys directory on
19237 VxWorks when using RTPs.
19238 (__gnat_set_env_value): Use setenv instead of putenv on VxWorks when
19240 (__gnat_dup): dup is available on Vxworks when using RTPs.
19241 (__gnat_dup2): dup2 is available on Vxworks when using RTPs.
19243 * cal.c: Use the header time.h for Vxworks 6.0 when using RTPs.
19245 * expect.c: The wait.h header is not located in the sys directory on
19246 VxWorks when using RTPs.

19267 * gsocket.h: Code imported from gen-soccon.c:
19268 Move all target-specific file inclusions and macro definitions to
19269 gsocket.h, in order to ensure that any C code in socket.c will see a set
19270 of constants that is consistent with the contents of g-soccon.ads.
19271 This change also makes gen-soccon self-contained (removing dependencies
19272 upon GCC internal headers).
19274 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
19276 (To_Inet_Addr): Now a procedure instead of a function, more efficient.
19278 * socket.c: Minor reformatting.

19408 Javier Miranda <miranda@adacore.com>
19410 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
19411 from object notation, the original node is unanalyzed and carries no
19412 semantic information, so that accessiblity checks must be performed on
19413 the type of the actual itself.
19414 (Expand_N_Subprogram_Declaration): Change last actual parameter for
19415 compatibility with Build_Protected_Sub_Specification.
19416 (Check_Overriding_Inherited_Interfaces): Add suport to handle

19423 implements at least one interface.
19425 * lib.ads: Extend information in Load_Stack to include whether a given
19426 load comes from a Limited_With_Clause.
19428 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
19429 whether a potential circularity is harmless, because it includes units
19430 loaded through a limited_with clause. Extends previous treatment which
19431 did not handle properly arbitrary combinations of limited and
19432 non-limited clauses.
19434 2005-09-01 Nicolas Setton <setton@adacore.com>
19436 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
19437 to be encoded as typ___XBLU_lowerbound__upperbound instead of

19466 2005-09-01 Laurent Pautet <pautet@adacore.com>
19468 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
19469 position set is provided, we compute one in order to reduce the maximum
19470 length of the keys. This computation first selects a character
19471 position between 1 and the minimum length of the keys in order to
19472 avoid reducing one of the keys to an empty string.
19473 (Initialize, Compute): When the ratio V to K is too low, the algorithm
19474 does not converge. The initialization procedure now comes with a
19475 maximum number of iterations such that when exceeded, an exception is
19476 raised in Compute. The user can initialize this ratio to another value
19478 Reformating and updated headers.

19482 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
19483 that given an entity T creates and returns an Itype that duplicates the
19484 contents of T. The returned Itype has the null-exclusion
19485 attribute set to True, and its Etype attribute references T
19486 to keep the association between the two entities.
19487 Update copyright notice

19499 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
19502 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
19504 Call Set_Result_Definition instead of Set_Subtype_Mark.
19505 (P_Subprogram_Specification): Add parsing of anonymous access result
19506 plus null exclusions. Call Set_Result_Definition instead of
19509 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
19510 (P_Access_Type_Definition): Add parsing for an anonymous access result
19511 subtype, plus parsing for null exclusions. Call Set_Result_Definition
19512 instead of Set_Subtype_Mark.
19514 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
19515 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
19516 (Result_Definition): New function for N_Function_Specifications.
19517 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
19518 N_Function_Specification.
19519 (Set_Null_Exclusion_Present): Allow this flag for
19520 N_Function_Specification.
19521 (Set_Result_Definition): New procedure for N_Function_Specifications.
19522 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
19523 and N_Function_Specification.
19525 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
19526 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
19527 Add support for LIMITED NEW for Ada 2005 AI-419
19528 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
19529 syntax for anonymous access results.

19536 N_Access_Function_Definition.
19538 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
19539 Result_Definition for cases of N_Access_Function_Definition and
19540 N_Function_Specification.
19541 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
19543 2005-09-01 Vincent Celier <celier@adacore.com>
19545 * lib-writ.adb: Update Copyright notice
19546 (Write_With_Lines): On platforms where file names are case-insensitive,
19547 record the file names in lower case.
19548 (Write_ALI): For D lines, on platforms where file names are
19549 case-insensitive, record the file names in lower case.
19551 2005-09-01 Ed Schonberg <schonberg@adacore.com>

19567 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
19568 including those that are inherited.
19570 2005-09-01 Robert Dewar <dewar@adacore.com>
19572 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
19574 * par-prag.adb: Implement new pragma Debug_Policy
19576 * sem_prag.adb Implement new pragma Debug_Policy
19577 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
19578 Component_Size attribute specification. Give warning for ignored pragma
19581 * snames.h, snames.ads, snames.adb: Introduce entries in
19582 Preset_Names for Name_Disp_Asynchronous_Select,
19583 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
19584 Name_Disp_Timed_Select.
19585 New pragma Debug_Policy
19587 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
19589 Switch -gnata also sets Debug_Pragmas_Enabled
19591 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
19592 handle an explicit -gnata when compiling predefined files.
19594 2005-09-01 Vincent Celier <celier@adacore.com>
19596 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
19597 directories of projects that have no Ada sources.
19599 2005-09-01 Robert Dewar <dewar@adacore.com>
19601 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
19602 (makes a difference for wide characters)
19604 * widechar.adb, widechar.ads:
19605 Add Wide_Char_Byte_Count feature to count chars vs bytes
19607 2005-09-01 Thomas Quinot <quinot@adacore.com>
19608 Ed Schonberg <schonberg@adacore.com>
19609 Robert Dewar <dewar@adacore.com>
19611 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
19612 'Address attribute reference with an overloaded prefix, use the
19613 location of the prefix (not the location of the attribute reference) as
19614 the error location.
19615 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
19616 a function renaming thereof, is a valid prefix for 'Size (where it is
19617 intepreted as a function call).
19618 (Statically_Denotes_Entity): New predicate to determine whether the
19619 prefix of an array attribute can be considered static.
19622 (Eval_Attr): Fix failure to evaluate Component_Size for
19623 unconstrained arrays (resulted in wrong value in packed case, since
19624 back end cannot handle this case)
19626 2005-09-01 Robert Dewar <dewar@adacore.com>
19628 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
19629 error msgs for most common cases.
19630 Use new errout insertion char < (conditional warning)
19632 2005-09-01 Javier Miranda <miranda@adacore.com>
19633 Ed Schonberg <schonberg@adacore.com>
19635 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
19636 become local to the whole package.
19637 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
19638 the package was already analyzed the new algorithm "replaces" the
19639 real entities by the shadow ones. This is required to ensure that
19640 the order of these entities in the homonym chains does not change;
19641 otherwise we can have undefined references at linking time because
19642 in case of conflicts the external name of the entities will have
19643 a suffix that depends on the order of the entities in the chain.
19644 (Remove_Limited_With_Clause): Complementary code that completes the
19645 new algorithm and replaces the shadow entities by the real ones.
19646 (Install_Limited_Withed_Unit): When unchaining entities before the
19647 installation of the shadow entities, only regular entities of the
19648 public part must be taken into account. This is required to
19649 keep this routine in synch with the work done by Remove_Limited_
19651 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
19652 even if unit is analyzed, because the analysis of the unit is
19653 idempotent in any case, and the limited view of the unit may have to
19654 be installed for proper visibility.
19655 (Expand_Limited_With_Clause): Even if the unit in the implicit
19656 with_clause has been analyzed already, a limited view of the package
19657 must be built for the current context, if it does not exist yet.
19659 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19660 Javier Miranda <miranda@adacore.com>
19661 Gary Dismukes <dismukes@adacore.com>
19663 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
19664 defining entity for the instance body, make a new defining identifier
19665 rather than copying the entity of the spec, to prevent accidental
19666 sharing of the entity list.
19667 (Check_Private_View): When exchanging views of private types, build the
19668 list of exchanged views as a stack, to ensure that on exit the exchanges
19669 are undone in the proper order.
19670 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
19671 Restore the compilation environment in case of instantiation_error.
19672 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
19673 for an anonymous access result.
19674 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
19675 (Formal_Entity): Handle properly the case of a formal package that
19676 denotes a generic package renaming.
19678 2005-09-01 Thomas Quinot <quinot@adacore.com>
19680 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
19681 clause if the array aggregate is surrounded by parentheses.
19683 2005-09-01 Cyrille Comar <comar@adacore.com>
19684 Gary Dismukes <dismukes@adacore.com>
19685 Ed Schonberg <schonberg@adacore.com>
19686 Javier Miranda <miranda@adacore.com>
19688 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
19690 to check if a type is Constrained in cases related to code generation
19691 (rather than semantic checking) since otherwise we do not generate
19692 similar code for mutable private types depending if their
19693 discriminants are visible or not.
19694 (Check_Abstract_Overriding): Do not complain about failure to override
19695 the primitive operations used in dispatching selects since they will
19696 always be overriden at the freeze point of the type.
19697 (Access_Definition): Separate out handling for resetting the scope
19698 of an anonymous access function result type. Retrieve the scope
19699 of the associated function rather than using Current_Scope, which
19700 does not have a consistent value (depends on whether we're in the
19701 middle of analyzing formal parameters). Add ??? comment about
19702 finding a cleaner way to handle the special cases of scope setting.
19703 (Process_Incomplete_Dependents): A protected operation is never a
19704 dispatching operation (only its wrapper may be).
19705 (Build_Derived_Record_Type): In case of tagged private types that
19706 implement interfaces add derivation of predefined primitive
19708 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
19709 by two parameters that are used in case of derivation from abstract
19710 interface types: No_Predefined_Prims is used to avoid the derivation
19711 of predefined primitives from the interface, and Predefined
19712 Prims_Only is used to complete the derivation predefined primitives
19713 in case of private tagged types implementing interfaces.
19714 Fix typo in comments
19715 (Find_Interface_In_Descendant): Protect the frontend against
19716 wrong code with large circularity chains.
19717 (Is_Private_Overriding): Add support for entities overriding interface
19718 subprograms. The test failed because Entities associated with overriden
19719 interface subprograms are always marked as hidden (and used to build
19720 the secondary dispatch table); in this case the overriden entity is
19721 available through the field abstract_interface_alias (cf. override_
19722 dispatching_operation)
19723 (Access_Definition): Set the scope of the type to Current_Scope for the
19724 case of a function with an anonymous access result type.
19725 (Access_Subprogram_Declaration): Handle creation of the type entity for
19726 an access-to-function type with an anonymous access result.
19727 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
19728 in handling for N_Access_Function_Definition.
19729 (Analyze_Subtype_Declaration): Modify the text of error message.
19730 (Derived_Type_Declaration): Modify the text of error message.
19731 (Process_Subtype): Modify the text of error message plus cleanup
19732 of one redundant error message.
19733 (Analyze_Component_Declaration): Code cleanup.
19734 (Analyze_Object_Declaration): Code cleanup.
19735 (Analyze_Subtype_Declaration): Propagate the null-exclusion
19736 attribute in case of access types. Code cleanup.
19737 (Array_Type_Declaration): Code cleanup.
19738 (Process_Discriminants): Create the new null-excluding itype
19739 if required. Code cleanup.
19740 (Process_Subtype): Create the new null-excluding itype if
19741 required. Code cleanup.
19742 (Build_Derived_Record_Type): Code cleanup to avoid calling
19743 twice the subprogram derive_subprograms in case of private
19744 types that implement interfaces. In this particular case the
19745 subprogram Complete_Subprograms_Derivation already does the
19746 job associated with the second call.
19748 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
19749 conversion to the full view when generating an operation for a
19750 discriminant whose type may currently be private.
19752 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19753 Javier Miranda <miranda@adacore.com>
19755 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
19756 V (Obj.F), the rewriting does not involve the indexed component, but
19757 only the selected component itself.
19758 Do not apply the transformation if the analyzed node is an actual of a
19759 call to another subprogram.
19760 (Complete_Object_Operation): Retain the entity of the
19761 dispatching operation in the selector of the rewritten node. The
19762 entity will be used in the expansion of dispatching selects.
19763 (Analyze_One_Call): Improve location of the error message associated
19765 (Analyze_Selected_Component): No need to resolve prefix when it is a
19766 function call, resolution is done when parent node is resolved, as
19768 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
19769 when attempting to resolve a call transformed from its object notation.
19770 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
19771 of the argument list for each interpretation of the operation.
19772 (Try_Object_Operation): The designated type of an access parameter may
19773 be an incomplete type obtained through a limited_with clause, in which
19774 case the primitive operations of the type are retrieved from its full
19776 (Analyze_Call): If this is an indirect call, and the return type of the
19777 access_to_subprogram is incomplete, use its full view if available.
19779 2005-09-01 Javier Miranda <miranda@adacore.com>
19780 Gary Dismukes <dismukes@adacore.com>
19782 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
19783 access types the null-exclusion and access-to-constant attributes must
19785 (Analyze_Return_Statement): When the result type is an anonymous access
19786 type, apply a conversion of the return expression to the access type
19787 to ensure that appropriate accessibility checks are performed.
19788 (Analyze_Return_Type): For the case of an anonymous access result type,
19789 generate the Itype and set Is_Local_Anonymous_Access on the type.
19790 Add ??? placeholder for check to disallow returning a limited object
19791 in Ada 2005 unless it's an aggregate or a result of a function call.
19792 Change calls from Subtype_Mark to Result_Definition.
19793 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
19794 Result_Definition in call to Make_Function_Specification.
19795 (Build_Body_To_Inline): Change Set_Subtype_Mark to
19796 Set_Result_Definition.
19797 (Make_Inequality_Operator): Change formal Subtype_Mark to
19798 Result_Definition in call to Make_Function_Specification.
19799 (Process_Formals): Create the new null-excluding itype if required.
19800 (New_Overloaded_Entity): For an entity overriding an interface primitive
19801 check if the entity also covers other abstract subprograms in the same
19802 scope. This is required to handle the general case, that is, overriding
19803 other interface primitives and overriding abstract subprograms inherited
19804 from some abstract ancestor type.
19805 (New_Overloaded_Entity): For an overriding entity that comes from
19806 source, note the operation that it overrides.
19807 (Check_Conformance, Type_Conformant): Addition of one new formal
19808 to skip controlling formals in the analysis. This is used to
19809 handle overloading of abstract interfaces.
19810 (Base_Types_Match): Add missing case for types imported from
19811 limited-with clauses
19812 (New_Overloaded_Entity): Add barrier to protect the use of
19813 the "alias" attribute.
19815 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19817 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
19818 verify that the procedure and the entry are mode conformant.
19819 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
19820 as a different operator, which is often a cut-and-paste error.
19822 2005-09-01 Javier Miranda <miranda@adacore.com>
19823 Ed Schonberg <schonberg@adacore.com>
19825 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
19826 used in controlling parameters exclude null because it is necessary to
19827 read the tag to dispatch, and null has no tag.
19828 (Override_Dispatching_Operation): If the previous operation is inherited
19829 from an interface, it becomes hidden and does not participate in later
19832 2005-09-01 Javier Miranda <miranda@adacore.com>
19833 Ed Schonberg <schonberg@adacore.com>
19834 Gary Dismukes <dismukes@adacore.com>
19836 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
19837 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
19838 the expander will generate the corresponding run-time check to evaluate
19840 (Resolve_Call): Check for legal type of procedure name or prefix that
19841 appears as a trigger in a triggering alternative.
19842 (Valid_Conversion): If expression is ambiguous and the context involves
19843 an extension of System, remove System.Address interpretations.
19844 (Resolve_Qualified_Expression): Reject the case of a specific-type
19845 qualification applied to a class-wide argument. Enhance comment
19846 to explain checking of Original_Node.
19847 (Resolve_Type_Conversion): The location of the error message was not
19848 general enough to handle the general case and hence it has been removed.
19849 In addition, this patch improves the text of the message.
19850 (Resolve_Type_Conversion): Add missing support for access to interface
19852 (Resolve_Type_Conversion): If the target is a class-wide interface type,
19853 do not expand if the expression is the actual in a call, because proper
19854 expansion will take place when the call itself is expanded.
19855 (Resolve_Allocator): If the context is an unchecked conversion, the
19856 allocator inherits its storage pool, if any, from the target type of
19859 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19860 Javier Miranda <miranda@adacore.com>
19862 * sem_type.adb (Add_One_Interp): If a candidate operation is an
19863 inherited interface operation that has an implementation, use the
19864 implementation to avoid spurious ambiguities.
19865 (Interface_Present_In_Ancestor): In case of concurrent types we can't
19866 use the Corresponding_Record_Typ attribute to look for the interface
19867 because it is set by the expander (and hence it is not always
19868 available). For this reason we traverse the list of interfaces
19869 (available in the parent of the concurrent type).
19870 (Interface_Present_In_Ancestor): Handle entities from the limited view
19872 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19874 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
19875 from the list of required components.
19876 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
19877 primitive procedure of a limited interface with a controlling first
19879 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
19881 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
19882 capture if it is generated in the second operand of a short-circuit
19884 Do not capture values for variables with address clauses.
19885 (Is_Object_Reference): Treat a function call as an object reference only
19886 if its type is not Standard_Void_Type.
19888 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19890 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
19891 to a variable that is statically known to be constant.

19903 Document that bounds of result of Base_Name match the input index
19905 Add documentation on environment variable syntax for Expand_Path
19907 * gnat_ugn.texi: Update documentation to include mention of -m switches
19908 Document new treatment of wide characters in max line length
19910 Remove -gnatL/-gnatZ switches, no longer used.
19911 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
19914 * gnat_rm.texi: Add doc for two argument form of pragma
19915 Float_Representation.
19916 Add documentation for pragma No_Strict_Aliasing
19917 Add note that explicit component clause overrides pragma Pack.

20673 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
20674 longer protected objects. They have been replaced by lower-level
20675 suspension objects made up by a mutex and a condition variable (or
20676 their equivalent given a particular OS) plus some internal data to
20677 reflect the state of the suspension object.
20678 (Initialize, Finalize): Add this initialization procedure for
20679 Suspension_Object, which is a controlled type.
20680 (Finalize): Add the finalization procedure for Suspension_Object,
20681 which is a controlled type.
20683 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
20684 Ada.Synchronous_Task_Control because there is no longer a need for a
20685 VxWorks specific version of this package. Target dependencies
20686 has been moved to System.Task_Primitives.Operations.
20688 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
20690 (InitializeCriticalSection, EnterCriticalSection,
20691 LeaveCriticalSection, DeleteCriticalSection): Replace the type
20692 pCriticalSection by an anonymous access type so that we avoid problems
20693 of accessibility to local objects.

20699 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
20700 set the environment task mask here.
20701 (Current_State): Add this function that returns the state of the
20703 (Set_False): Add this procedure that sets the state of the suspension
20705 (Set_True): Add this procedure that sets the state of the suspension
20706 object to True, releasing the task that was suspended, if any.
20707 (Suspend_Until_True): Add this procedure that blocks the calling task
20708 until the state of the object is True. Program_Error is raised if
20709 another task is already waiting on that suspension object.
20710 (Initialize): Add this procedure for initializing the suspension
20711 object. It initializes the mutex and the condition variable which are
20712 used for synchronization and queuing, and it sets the internal state
20714 (Finalize): Add this procedure for finalizing the suspension object,
20715 destroying the mutex and the condition variable.

21164 in the case where the target type is an anonymous access type of an
21165 object or component (that is, when Is_Local_Anonymous_Access is true).
21166 Prevent the special checks for conversions of access discriminants in
21167 the case where the discriminant belongs to a nonlimited type, since
21168 such discriminants have their accessibility level defined in the same
21169 way as a normal component of an anonymous access type.
21170 (Resolve_Allocator): When an allocator's designated type is a class-wide
21171 type, check that the accessibility level of type given in the
21172 allocator's expression or subtype indication is not statically deeper

21184 (Resolve_Actuals): Enable full error reporting on view conversions
21185 between unrelated by_reference array types.
21186 The rule for view conversions of arrays with aliased components is
21187 weakened in Ada 2005.
21188 Call to obsolescent subprogram is now considered to be a violation of
21189 pragma Restrictions (No_Obsolescent_Features).

21230 both bound checks, rather than a conjunction.
21231 (Insert_Valid_Check): If the expression is an actual that is an indexed
21232 component of a bit-packed array, force expansion of the packed element
21233 reference, because it is specifically inhibited elsewhere.

21246 may be deallocated by Normalize_Arguments.
21247 (Collect_Arguments): Eliminate empty arguments
21249 * gnatcmd.adb (All_Projects): New Boolean flag, initialized to False,
21250 and set to True when -U is used for GNAT PRETTY or GNAT METRIC.

22200 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
22201 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
22202 analyzed if expansion is disabled (which could otherwise cause spurious
22203 error messages if expansion has been disabled due to previous
22204 (unrelated) errors).
22206 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
22207 is disabled, the entity denoted by the argument is the access type
22208 itself, not an underlying record type, so there is no need to go back
22209 to the Corresponding_Remote_Type.

22219 denotes a type in the class.
22220 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
22221 of Name_Generic_Dispatching_Constructor.
22223 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

22241 a class-wide stream attribute) and then rewrite the attribute name
22242 as the name of the appropriate compiler-generated stream primitive.

22254 itype whose parent is controlled and not yet frozen, do not create a
22255 freeze node for the itype if expansion is disabled.
22257 2005-03-29 Vincent Celier <celier@adacore.com>
22259 * make.adb (Gnatmake): Don't fail if the main project file is declared
22260 as having no Ada sources. Do not display message "no sources to

22281 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
22282 rather than proceed ahead using a junk attribute name.
22284 2005-03-29 Vincent Celier <celier@adacore.com>
22286 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
22288 * prj-part.adb (Parse_Single_Project): Set the location of a project
22289 on its defining identifier, rather than on the reserved word "project".
22291 * prj-proc.adb (Expression): Adapt to the fact that default of external
22292 references may be string expressions, not always literal strings.
22293 (Recursive_Process): Set Display_Name equal to Name
22294 when Location is No_Location, that is when there is no actual file.
22295 Get the Display_Name of the project from the source, when it is not a
22297 (Process): Use the Display_Name in error messages
22299 * prj-strt.adb (External_Reference): Allow default to be string
22300 expressions, not only literal strings.

22325 subtype if code is being pre-analyzed, to prevent un-expanded
22326 references to protected formals, among others.
22327 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
22328 interpretation that can be a call, include the result of the call as a
22329 possible interpretation of the dereference.
22331 * sem_ch5.adb (Process_Bounds): Determine type of range by
22332 pre-analyzing a copy of the original range, and then analyze the range
22333 with the expected type.
22335 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
22336 with an overloaded prefix where not all interpretations yield an
22337 access to subprogram, do not rewrite node as a call.
22338 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
22339 the node as a call once the context identifies the interpretation of
22340 the prefix whose call yields the context type.
22341 (Valid_Conversion): For the case of a conversion between
22342 local access-to-subprogram types, check subtype conformance using
22343 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more

22348 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
22349 indicator, indicate that the formal can never be null.
22350 (Process_Formals): If a formal has a non_null indicator, insert the
22351 resulting subtype immediately before the enclosing subprogram decl,
22352 and not at the beginning of the corresponding declarative part, to
22353 prevent access before elaboration (Ada2005).

22480 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
22481 Determine whether to generate a default implementation for each stream
22482 attribute separately, as this depends on the specific attribute.

23071 Ed Schonberg <schonberg@adacore.com>
23077 * decl.c (gnat_to_gnu_field): Reject aliased components with a
23078 representation clause that prescribes a size not equal to the rounded
23079 size of their types.
23080 (gnat_to_gnu_entity, case E_Component): Always look at
23081 Original_Record_Component if Present and not the entity.
23082 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
23083 of tagged extension types by not making field for components that are
23085 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
23086 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
23087 expression to the type of the object when the object is constant.
23088 Reverse defer_debug_incomplete_list before traversing it, so that trees
23089 are processed in the order at which they were added to the list. This
23090 order is important when using the stabs debug format.
23091 If we are deferring the output of debug information, also defer this
23092 output for a function return type.
23093 When adding fields to a record, prevent emitting debug information
23094 for incomplete records, emit the information only when the record is
23096 (components_to_record): New parameter defer_debug.
23097 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
23098 (gnat_to_gnu_field_decl): New function.
23099 (substitution_list, annotate_rep): Call it.
23100 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
23101 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
23102 No longer update discriminants to not be a COMPONENT_REF.
23103 (copy_alias_set): Strip padding from input type; also handle
23104 unconstrained arrays properly.
23106 * gigi.h (write_record_type_debug_info): New function.
23107 Convert to use ANSI-style prototypes. Remove unused
23108 declarations for emit_stack_check, elab_all_gnat and
23109 set_second_error_entity.
23110 (gnat_to_gnu_field_decl): New decl.
23112 * utils.c (write_record_type_debug_info): New function.
23113 (finish_record_type): Delegate generation of debug information to
23114 write_record_type_debug_info.
23115 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
23116 (update_pointer_to): Fix pasto.
23117 (convert) <UNION_TYPE>: Accept slight type variations when
23118 converting to an unchecked union type.
23120 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
23121 replace the N_Freeze_Entity with a null statement.
23123 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
23124 within a constrained subcomponent of an enclosing record, place the
23125 freeze nodes in the scope stack entry for the enclosing record.
23126 (Undelay_Type): New Subprogram.
23127 (Set_Small_Size): Pass T, the type to modify; all callers changed.
23128 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
23129 within records; allow them to have freeze nodes if their base types
23132 * exp_util.adb (Remove_Side_Effects): Properly test for
23133 Expansion_Delayed and handle case when it's inside an
23134 N_Qualified_Expression.
23136 * sem_ch3.adb (Derived_Type_Declaration): New predicate
23137 Comes_From_Generic, to recognize accurately that the parent type in a
23138 derived type declaration can be traced back to a formal type, because
23139 it is one or is derived from one, or because its completion is derived
23141 (Constrain_Component_Type): If component comes from source and has no
23142 explicit constraint, no need to constrain in in a subtype of the
23144 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
23145 Minor change to propagate Is_Ada_2005 flag
23147 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
23148 Expansion_Delayed is False.
23149 (assoc_to_constructor): Ignore fields that have a
23150 Corresponding_Discriminant.
23151 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
23152 function returns "by target", dereference the target pointer using the
23153 type of the actual return value.
23154 <all>: Be prepared for a null gnu_result.
23155 (processed_inline_subprograms): Check flag_really_no_inline
23156 instead of flag_no_inline.
23157 (set_second_error_entity): Remove unused function.

23162 2005-03-15 Robert Dewar <dewar@adacore.com>
23163 Ed Schonberg <schonberg@adacore.com>
23164 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
23166 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
23167 Must_Be_Byte_Aligned for cases where we do not need to use a
23168 System.Pack_nn unit.
23170 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
23172 Needed now that we do some processing for IN parameters as well. This
23173 may well fix some unrelated errors.
23174 (Expand_Call): Handle case of unaligned objects (in particular those
23175 that come from packed arrays).
23176 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
23177 renamed entity is an inherited operation, re-expand the call using the
23178 original operation, which is the one to call.
23179 Detect attempt to inline parameterless recursive subprogram.
23180 (Represented_As_Scalar): Fix to work properly with private types
23181 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
23182 accurate estimate. Yields True in far fewer cases than before,
23183 improving the quality of code that depends on this test.
23185 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
23186 over both visible and private declarations to remove them from tree,
23187 and mark subprograms declared in package as eliminated, to prevent
23188 spurious use in subsequent compilation of generic units in the context.
23190 * exp_util.ads: Minor cleanup in variable names
23192 * sem_eval.ads, sem_eval.adb: Minor reformatting
23193 (Compile_Time_Known_Bounds): New function
23195 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23197 * exp_ch7.adb (Convert_View): Use base types of underlying types when
23198 determining whether an unchecked conversion is needed for the argument
23199 of an initialization call.
23201 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23203 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
23204 that appears in the instantiation rather than the internal subtype
23205 generated in the wrapper package, to avoid anomalies in gigi when the
23206 target is derived from a private type whose full view is an access type.
23208 2005-03-15 Robert Dewar <dewar@adacore.com>
23210 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
23212 Add documentation to replace the use of this flag
23213 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
23216 2005-03-15 Thomas Quinot <quinot@adacore.com>
23218 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
23219 here from exp_attr so it can be shared between exp_attr and exp_dist.
23220 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
23221 all TSS names, not a subset thereof, and the previous name introduced
23222 an unnecessarily confusion that a distinction might exist between
23223 "OK" TSS names and some "not OK" TSS names.
23225 2005-03-15 Doug Rupp <rupp@adacore.com>
23227 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
23230 2005-03-15 Pascal Obry <obry@adacore.com>
23231 Eric Botcazou <ebotcazou@adacore.com>
23235 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
23236 when IN_RTS. This is to work around a bootstrap path problem.
23238 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
23239 table and pass it to __gnat_install_SEH_handler().
23240 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
23242 * lang.opt: Fix specification of -fRTS=.
23244 2005-03-15 Doug Rupp <rupp@adacore.com>
23245 Bernard Banner <banner@adacore.com>
23246 Vincent Celier <celier@adacore.com>
23247 Arnaud Charlet <charlet@adacore.com>
23250 This change works fine when gnatlib is built from the gcc directory,
23251 but does not work when using the libada Makefile, since GCC_FOR_TARGET
23252 is not passed to ada/Makefile.in, so more work is needed by a
23253 Makefile/configure expert.
23255 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
23256 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
23257 Setup gnatlink switch -M for x86_64 linux, as it is already setup
23259 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
23260 Run ranlib on libgccprefix.a
23261 Define PREFIX_OBJS for Darwin, to build libgccprefix.
23262 (ADA_INCLUDE_SRCS): Split Ada packages.
23264 2005-03-15 Robert Dewar <dewar@adacore.com>
23266 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
23268 * impunit.adb: Add GNAT.UTF_32
23270 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
23272 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
23273 now uses GNAT.UTF_32).
23275 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
23276 capabilities for categorizing characters using Unicode categories
23278 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23280 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
23281 instantiation that has been rewritten as a package body, retrieve spec
23282 to generate proper name for implicit_with_clause.
23283 (Install_Parents): Recognize a parent that is an instantiation but has
23284 been rewritten as a package declaration during analysis.
23286 2005-03-15 Javier Miranda <miranda@adacore.com>
23287 Ed Schonberg <schonberg@adacore.com>
23289 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
23290 parameter reported some error we immediately return. This improves the
23291 behaviour of the frontend in case of errors.
23292 (Install_Parent, Remove_Parent): Introduce new flag
23293 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
23294 ancestor of a generic child unit, when the child is being instantiated.
23295 (Inline_Instance_Body): If we are compiling the private
23296 part or the body of a child unit, restore the proper visibility of the
23297 parents after compiling the instance body.
23299 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23300 Javier Miranda <miranda@adacore.com>
23303 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
23304 of a private type, in which case it is underlying_type that denotes
23305 the proper task. Also modified to use the new entity attribute
23306 that is directly available in the task type and task subtype entities
23307 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
23308 arrays when other dimensions than the first are constrained by
23309 discriminants of an enclosing record.
23310 (Insert_Explicit_Dereference): If the prefix is an indexed component or
23311 a combination of indexed and selected components, find ultimate entity
23312 and generate the appropriate reference for it, to suppress spurious
23314 (Note_Possible_Modification): If an entity name has no entity, return.
23315 (Is_Variable): A function call never denotes a variable.
23316 (Requires_Transient_Scope): For record types, recurse only on
23317 components, not on internal subtypes that may have been generated for
23318 constrained components.
23320 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23322 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
23323 Eliminated as candidates for resolution. Both efficient, and avoids
23324 anomalies with operators declared in deleted code.
23325 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
23326 expansion is disabled (as when compiling a generic) to prevent spurious
23327 warnings on prefixes of selected components.
23329 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23331 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
23332 attached to a list before checking whether it appears in the private
23333 declarations of the current package.
23334 (Make_Inequality_Operator): Insert declaration in proper declarative
23335 list rather than just setting the Parent field, so that
23336 Is_Private_Declaration can handle it properly.
23338 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23340 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
23341 a renaming a body, check that the renamed subprogram in not intrinsic.
23342 (Find_Direct_Name): If several use_visible entities hide
23343 each other, and the context is a predefined file compiled through
23344 rtsfind, keep only the entity that comes from a predefined file.
23346 2005-03-15 Geert Bosch <bosch@adacore.com>
23348 * s-fatgen.adb (Valid): Extend special exceptions to account for long
23349 long float padding to also cover AMD64 and IA64.
23351 2005-03-15 Gary Dismukes <dismukes@adacore.com>
23353 * s-imgwch.adb: Add with and use of Interfaces.
23354 (Img_Wide_Character): Change type of Val to Unsigned_16.
23355 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
23357 2005-03-15 Matthew Gingell <gingell@adacore.com>

23365 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
23367 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
23369 2005-03-15 Robert Dewar <dewar@adacore.com>

23393 procedures in the bug boxes for various GNAT builds.
23395 2005-03-15 Vincent Celier <celier@adacore.com>
23397 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

23400 Arnaud Charlet <charlet@adacore.com>
23401 Robert Dewar <dewar@adacore.com>
23402 Cyrille Comar <comar@adacore.com>
23403 Sergey Rybin <rybin@adacore.com>
23405 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
23406 too specific and long-winded to be appropriate for the GNAT User's
23408 Warn about use of GCC switches not documented in the GNAT User's Guide,
23409 as these may cause generated code to not conform to Ada semantics.
23410 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
23411 Add documentation for -gnat95 and -gnat05 switches
23412 Remove paragraph documenting obsolete way to refer to third party
23414 Add a few references to Ada_05 that were missing.
23415 Update documentation on -gnatZ/-gnatL.

23535 Clean up unused entity.
23537 * exp_ch3.ads, exp_ch3.adb: Fix various places where Wide_Wide_String
23538 was not taken into account.
23539 This includes proper initialization with Normalize_Scalars.
23540 (Get_Simple_Init_Val): Major rewrite for initialize scalars and
23541 normalize scalars cases (particularly the latter) to do a better job
23542 of finding invalid representations.

23831 the formal subprogram.
23832 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
23833 which is an unclean use of that field, we set the new field

23860 procedure", covering the case of a call to a formal abstract procedure
23861 that has statically tagged operands.

23863 a tag-indeterminate function call whose type is an ancestor of the

24031 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
24032 [VMS]: Add translations for g-enblsp.adb.

24059 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
24060 with expansion disabled. The actual subtype is needed among other
24061 places when the selected component appears in the context of a loop
24062 bound, and denotes a packed array.
24063 (Operator_Check): Always use the first subtype in the
24064 error message, to avoid the appearance of internal base types.
24065 (Transform_Object_Operation): Copy each actual in full
24066 to the parameter associations of the constructed call, rather than
24067 using the shallow copy mechanism of New_Copy_List. This ensures that
24068 the chaining of named associations is done properly.
24069 (Complete_Object_Operation): Rewrite node, rather than
24070 replacing it, so that we can trace back to the original selected
24073 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
24074 and calls that use object notation, if the called function is not
24075 declared in a withed unit, place the elaboration constraint on the
24076 unit in the context that makes the function accessible.
24077 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
24078 imposes an elaboration constraint between two packages.
24080 2005-02-09 Ed Schonberg <schonberg@adacore.com>
24082 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
24083 views of a private type after handling its private dependents, to
24084 maintain proper stack discipline between entry and exit from the
24087 2005-02-09 Cyrille Comar <comar@adacore.com>
24089 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

24104 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
24105 Slight fix to documentation of -gnaty with no parameters
24107 * xr_tabls.ads: Add ??? comment for missing overall comment
24109 * xsinfo.adb: Make default file name be sinfo.h, since this is what
24110 we now use by default.
24112 * xsnames.adb: Adjust end of file test to look for five space followed
24113 by '#' instead of six spaces. The format of xsnames.adb was modified
24114 in the last update.
24116 * a-numeri.ads: Add reference to AI-388 for greek letter pi
24119 * clean.adb: Minor reformatting.
24121 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
24122 gnatname.adb: Minor reformatting
24123 Add 2005 to copyright output when utility is run
24125 * csets.adb: Eliminate obsolete comment
24127 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
24130 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
24132 2005-02-09 Sergey Rybin <rybin@adacore.com>
24134 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
24135 the difference between compact and incompact layout and add the record
24136 representation clause to the example illustrating different layouts.
24137 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
24138 component clauses").
24140 2005-02-09 Florian Villoing <villoing@adacore.com>
24142 * gnat_ugn.texi: Fix typos.
24143 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
24145 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
24146 in the generated documentation.
24148 2005-02-09 Arnaud Charlet <charlet@adacore.com>
24150 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
24152 Update linker wrapper when linking with non GNU C++.

24190 * exp_util.ads: Minor correction in comment.
24192 2005-02-09 Arnaud Charlet <charlet@adacore.com>
24194 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
24195 since this procedure is now too complex to be worth inlining.

24199 * utils.c (gnat_define_builtin): Remove.
24200 (gnat_install_builtins): Use build_common_builtin_nodes.

24442 2005-01-03 Olivier Hainque <hainque@adacore.com>
24444 * decl.c (compatible_signatures_p): New function. The intended purpose
24445 is to check if two function signatures for a call-site and a callee are
24446 compatible enough for the call to be valid. The underlying purpose is
24447 to check if a call to a mapped builtin is using the right interface.
24448 The current code actually does not check antyhing - this a placeholder
24449 for future refinements.

24869 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
24870 dereference is rewritten to an explicit one, generate a reference to

24991 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
24992 is a non-overloaded implicit dereference, call the above subprogram to
24993 ensure proper recording of references.
24995 2004-12-07 Gary Dismukes <dismukes@adacore.com>
24997 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

25036 Sergey Rybin <rybin@adacore.com>
25038 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
25039 Files" with the new tool and package names.
25040 Reformatting to suppress most of the warnings for line too long
25041 Document the new section "Project Search Path:" in the output of
25043 Add gnatmetric section
25045 2004-12-07 Vincent Celier <celier@adacore.com>
25047 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
25048 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
25049 and -eit to -ept. Added qualifier
25050 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
25052 2004-11-27 Andreas Schwab <schwab@suse.de>
25054 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
25056 2004-11-25 Arnaud Charlet <charlet@adacore.com>
25058 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
25059 internal implementation unit GNAT.Sockets.Thin,
25060 as their usage for sockets is non-portable (using the read and write
25061 functions from the system runtime library is fine on UNIX but won't
25062 work under Windows).
25064 * mingw32.h: Update copyright notice.
25066 2004-11-25 Arnaud Charlet <charlet@adacore.com>
25068 * ada-tree.h: Minor reformatting of previous change to avoid lines
25069 longer than 79 characters.

25090 Style_Check_Order_Subprograms.
25092 2004-11-18 Arnaud Charlet <charlet@adacore.com>
25094 * adaint.h, adaint.c
25095 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
25097 Add also a cast to kill another warning.
25098 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
25099 parameter with the priority class of the parent process instead of
25100 always using the NORMAL_PRIORITY_CLASS.
25101 (__gnat_dup): New function.
25102 (__gnat_dup2): New function.
25103 (__gnat_is_symbolic_link): Enable the effective body of this
25104 function when __APPLE__ is defined.
25106 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
25109 2004-11-18 Olivier Hainque <hainque@adacore.com>
25111 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
25112 address of which may be used to represent "others" and "all others"
25113 choices in exception tables, instead of the current harcoded
25114 (void *)0 and (void *)1.
25115 (Setup_Exception): Do nothing in the GNAT SJLJ case.
25117 * gigi.h (others_decl, all_others_decl): New decls representing the
25118 new Others_Value and All_Others_Value objects.
25119 (struct attrib): Rename "arg" component as "args", since GCC expects a
25120 list of arguments in there.
25122 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
25123 corresponding objects exported by a-exexpr, instead of hardcoded dummy
25126 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
25127 others_decl and all_others_decl instead of hardcoded dummy addresses
25128 to represent "others" and "all others" choices, which is cleaner and
25129 more flexible with respect to the possible eh pointer encoding policies.
25131 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
25132 (process_attributes): Account for the naming change of the "args"
25133 attribute list entry component.
25135 * decl.c (build_attr_list): Rename into prepend_attributes to allow
25136 cumulating attributes for different entities into a single list.
25137 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
25138 attributes for the current entity and propagate first subtype
25139 attributes to other subtypes.
25140 <E_Procedure>: Attribute arguments are attr->args and not
25141 attr->arg any more.
25142 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
25143 argument provided, as this is what GCC expects. Use NULL_TREE instead
25146 2004-11-18 Robert Dewar <dewar@adacore.com>
25148 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
25149 Minor reformatting througout (including new function specs)
25150 Add ??? comments asking for clarification.
25152 2004-11-18 Thomas Quinot <quinot@adacore.com>
25154 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
25155 incomplete duplicate implementation of this subprogram from butil.
25157 2004-11-18 Thomas Quinot <quinot@adacore.com>
25159 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
25160 procedures factors the common processing for building an RPC receiver
25161 for an RCI package or an RACW type.
25162 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
25163 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
25164 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
25166 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
25168 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
25170 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
25171 distribution subprogram identifiers that are either subprogram numbers

25174 string distribution identifiers assigned to a given subprogram.
25175 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
25176 (Add_RAS_Dereference_TSS): Add comments.
25177 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
25178 is not referenced yet because it will be used by the PolyORB DSA
25180 (Insert_Partition_Check): Remove fossile code.
25181 (First_RCI_Subprogram_Id): Document this constant.
25182 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
25184 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
25185 replaced with calls to Get_Library_Unit_Name_String. Previously there
25186 were several instances of the same code in different locations in the
25187 compiler; this checkin completes the replacement of all of these
25188 instances with calls to a common subprogram.
25189 Minor reformatting.
25191 * sem_dist.adb: Remove comment noting that RPC receiver generation
25192 should be disabled for RACWs that implement RASs.
25193 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
25195 * sem_util.ads, sem_util.adb (Has_Stream): New function

25197 qualified name of a library unit into the name buffer.
25198 (Note_Possible_Modification): Generate a reference only
25199 if the context comes from source.
25201 * snames.ads (PCS_Names): New subtype corresponding to names of
25202 supported implementations of the Partition Communication Subsystem
25203 (PCS) (i.e. the runtime library support modules for the distributed

25213 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
25215 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
25217 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
25218 (Expand_Pragma_Psect_Object): New procedure
25219 These procedures contain the revised and cleaned up processing for
25220 these two pragmas. This processing was formerly in Sem_Prag, but
25221 is more appropriately moved here. The cleanup involves making sure
25222 that the pragmas are properly attached to the tree, and that no
25223 nodes are improperly shared.
25225 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
25226 pragmas to Exp_Prag, which is more appropriate.
25227 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
25228 check for duplicates Remove use of Is_Psected flag, no longer needed.
25229 Use new Make_String_Literal function with string.
25231 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
25232 that are functions return universal values, that have to be converted
25233 to the context type.
25234 Use new Make_String_Literal function with string.
25235 (Get_Stream_Convert_Pragma): New function, replaces the use of
25236 Get_Rep_Pragma, which had to be kludged to work in this case.
25238 * freeze.adb: Use new Has_Rep_Pragma function
25240 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
25241 function with string.
25242 Use new Has_Rep_Pragma function.
25244 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
25247 2004-11-18 Robert Dewar <dewar@adacore.com>
25249 * errout.ads, errout.adb: (First_Sloc): New function
25251 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
25252 check (-gnatyx) instead of being included as a redundant construct
25255 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
25256 Style_Check_Order_Subprograms.
25258 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
25259 stylesw.adb: Add Style_Check_Xtra_Parens
25261 * usage.adb: Add line for -gnatyx (check extra parens)
25263 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
25265 2004-11-18 Ed Schonberg <schonberg@adacore.com>
25266 Robert Dewar <dewar@adacore.com>
25268 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
25269 discriminant of a constrained subtype, analyze the copy of the
25270 corresponding constraint, because in some cases it may be only
25271 partially analyzed.
25272 Removes long-lived ??? comments.
25274 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
25275 handled controlled or secondary-stack expressions within the
25276 iteration_scheme of a loop.
25278 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
25279 bounds that may contain functions calls, to prevent memory leaks when
25280 the bound contains a call to a function that uses the secondary stack.
25281 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
25282 generate temporaries for loop bounds that might contain function calls
25283 that require secondary stack and/or finalization actions.
25285 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
25286 selected component and the selector is overloadable (not just a
25287 function) treat as function call, Analyze_Call will disambiguate if
25289 (Analyze_Selected_Component): Do not generate an actual subtype for the
25290 selected component if expansion is disabled. The actual subtype is only
25291 needed for constraint checks.
25292 (Analyze_Allocator): If restriction No_Streams is set, then do
25293 not permit objects to be declared of a stream type, or of a
25294 composite type containing a stream.
25296 * restrict.ads: Remove the a-stream entry from Unit_Array, since
25297 No_Streams no longer prohibits with'ing this package.
25299 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
25300 discriminants, but the parent base has unknown discriminants, there is
25301 no discriminant constraint to inherit. Such a discrepancy can arise
25302 when the actual for a formal type with unknown discriminants is a
25303 similar private type whose full view has discriminants.
25304 (Analyze_Object_Declaration): If restriction No_Streams is set, then
25305 do not permit objects to be declared of a stream type, or of a
25306 composite type containing a stream.
25308 2004-11-18 Ed Schonberg <schonberg@adacore.com>
25310 * exp_dbug.ads: Update documentation to reflect simpler encoding for
25311 protected operations.
25313 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
25314 generated name, it complicates decoding in gdb and hinders debugging
25315 of protected operations.
25316 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
25317 flag for the protected entry barrier function.
25318 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
25319 flag for the protected entry function.

25323 * expect.c: Define __unix__ when __APPLE__ is defined.
25325 * Makefile.in: Inform the value of the variable GMEM_LIB in the
25326 Darwin-specific section.
25328 * lang-specs.h: Change the placement of the %1 marker.
25329 Works around the fact that gcc adds -fPIC by default under Darwin.
25331 2004-11-18 Ed Schonberg <schonberg@adacore.com>
25333 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
25334 type of the object with the packed array type, set the Analyzed flag
25335 on the object if it is an entity or simple indexed component, to avoid
25336 spurious type errors.
25338 2004-11-18 Gary Dismukes <dismukes@adacore.com>
25340 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
25341 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
25342 separate line from the version message.
25344 2004-11-18 Ed Falis <falis@adacore.com>
25346 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
25348 (init_float): Eliminate initialization of floating point status for
25349 AE653. The instructions have no effect for vThreads.
25351 2004-11-18 Vincent Celier <celier@adacore.com>
25353 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
25354 gnatbind is invoked with -shared.
25356 2004-11-18 Jose Ruiz <ruiz@adacore.com>
25358 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
25359 for Detect_Blocking which is redundant with the check done within the
25360 procedure Protected_Single_Entry_Call.
25361 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
25362 Detect_Blocking which is redundant with the check done within the
25363 procedure Protected_Single_Entry_Call.
25365 2004-11-18 Vincent Celier <celier@adacore.com>
25367 * makegpr.adb (Compile): Put the compiling switches (in package
25368 Compiler and on the command line) immediately after "-c", instead of
25369 at the end of the command line invocation of the compiler, when
25370 compiling a non-Ada file.
25371 (Build_Global_Archive): When there is no need to rebuild the archive,
25372 set Global_Archive_Exists, so that the archive is passed to the linker
25375 2004-11-18 Robert Dewar <dewar@adacore.com>
25376 Sergey Rybin <rybin@adacore.com>
25379 Remove extra paren check from list of checks for redundant constructs
25380 Add documentation of new -gnatyx style check (check extra parens)
25381 Remove paragraph about gnatelim debug options.
25383 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
25384 objects rather than forbidding dependencies on the package Ada.Streams.
25386 * sinfo.ads: Add ??? note that we should document pragmas passed to
25389 * g-expect.ads: Fix a few typos in the comments.
25391 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
25393 * misc.c (gnat_handle_option): Use %< and %> for quoting in
25396 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
25398 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
25400 2004-11-07 Andreas Schwab <schwab@suse.de>
25402 * Makefile.in (install-gnatlib): Remove spurious hyphen.
25404 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
25407 * Makefile.in (darwin): Set soext to .dylib.
25409 2004-10-26 Vincent Celier <celier@gnat.com>
25410 Thomas Quinot <quinot@act-europe.fr>
25412 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
25413 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
25414 there is no use of GNAT.Sockets.Constants.
25415 Remove remaining pragma Import for C_Write
25416 Remove C_Read and C_Write from internal implementation unit
25417 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
25418 the read and write functions from the system runtime library is fine
25419 on UNIX but won't work under Windows).
25421 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
25422 (Check_Selector): Use C_Recv instead of C_Read.
25423 Selectors are the GNAT.Sockets abstraction to perform a select()
25424 call on a set of descriptors. To allow abortion of an ongoing
25425 select operation, some data is written to a dedicated socket that
25426 is always monitored.
25427 Under Windows, the write and read library functions cannot operate
25428 on sockets, so we need to use send and recv instead, which is portable
25429 across all supported platforms.
25431 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
25432 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
25433 (using the read and write functions from the system runtime library is
25434 fine on UNIX but won't work under Windows).
25436 2004-10-26 Nicolas Setton <setton@act-europe.fr>
25438 * mlib-tgt-darwin.adb: New file.
25440 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
25441 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
25442 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
25443 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
25446 * Makefile.in: Add support for building shared libraries under Darwin.
25447 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
25448 the low level EH init subprogram to be called from __gnat_initialize.
25450 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
25451 indicates which options to pass to the archive indexer.
25453 * mlib-utl.adb: Add support for calling ranlib with additional
25454 options. This is needed for instance under Mac OS X.
25455 (Ranlib_Options): New global variable, used to store the potential
25456 options to pass to ranlib.
25457 (Ar): Use Ranlib_Options when spawning ranlib.
25458 (Initialize): Set the value of ranlib option.
25460 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
25462 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
25463 instead of 8K, to reflect the real potential needs for stack-checking
25466 2004-10-26 Pascal Obry <obry@gnat.com>
25468 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
25470 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
25471 Windows only the initial thread stack size can be set so it is good to
25472 start we a low stack size.
25473 The OS will adjust the size as needed.
25475 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
25476 Nicolas Setton <setton@act-europe.fr>
25478 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
25479 "__unix__" instead of "unix".
25480 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
25481 sections were just mistakenly ignored. The former is
25482 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
25483 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
25484 of hpux. This prevents an unwanted definition of the symbol
25485 convert_addresses in adaint.o.
25487 2004-10-26 Gary Dismukes <dismukes@gnat.com>
25489 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
25490 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
25492 2004-10-26 Cyrille Comar <comar@act-europe.fr>
25494 * a-filico.ads, a-filico.adb: fix incorrect header.
25496 2004-10-26 Javier Miranda <miranda@gnat.com>
25498 * a-ststio.ads: Fix typo in identifier
25500 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25502 * sem_ch4.adb: Minor reformatting.
25504 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25506 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
25507 enabled, check the result of unary and binary operations when the
25508 expression is the right-hand side of an assignment.
25510 2004-10-26 Vincent Celier <celier@gnat.com>
25512 * clean.adb (Delete): Do not output warnings when in quiet output and
25513 not in verbose mode.
25514 (Force_Deletions): New Boolean flag, defaulted to False
25515 (Delete): Only delete a file if it is writable, and when
25516 Force_Deletions is True.
25517 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
25518 (Usage): Line for new switch -f
25519 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
25522 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
25524 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
25525 JM type only if its size matches that of the wrapper. When a size is
25526 prescribed and the field is not aliased, remove the wrapper of a JM
25527 type only if the size is not greater than that of the packed array.
25528 (gnat_to_gnu_entity): Change the extension of packed array wrappers
25531 2004-10-26 Geert Bosch <bosch@gnat.com>
25533 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
25534 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
25535 (Pred): Implement in terms of Succ.
25537 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25539 * exp_aggr.adb (Safe_Component): An aggregate component that is an
25540 unchecked conversion is safe for in-place use if the expression of the
25541 conversion is safe.
25542 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
25543 be expandable in place even if the aggregate does not come from source.
25544 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
25545 designated object of an allocator in place, rather than building it
25546 first on the stack. The previous scheme forces a full copy of the array,
25547 and may be altogether unsusable if the size of the array is too large
25548 for stack allocation.
25550 2004-10-26 Robert Dewar <dewar@gnat.com>
25552 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
25553 compares if the component is atomic.
25555 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
25556 array assignment if the component type is atomic.
25558 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25559 Eric Botcazou <ebotcazou@act-europe.fr>
25561 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
25562 is aliased and is a by_reference type, do not pass by copy.
25563 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
25564 detect whether the call is in the right side of an assignment or
25565 the expression of an object declaration. Recurse on component
25566 association within aggregates.
25567 Call it in the condition that determines whether the temporary is
25568 necessary for correct stack-checking.
25570 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25572 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
25573 RACW_Type, used in the PolyORB version.
25574 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
25575 version and the GARLIC version.
25577 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
25578 Rename RCI_Info to RCI_Locator for better consistency between the
25579 GARLIC and PolyORB versions of the distributed systems annex.
25580 (DSA_Implementation_Name): This enumeration lists the possible
25581 implementations of the Partition Communication Subsystem for the
25582 Distributed Systems Annex (DSA). The three available implementations
25583 are the dummy stub implementation (No_DSA), and two versions based on
25584 two different distribution runtime libraries: GARLIC and PolyORB. Both
25585 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
25587 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
25590 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
25591 between the GARLIC and PolyORB versions of the distributed systems
25593 Remove RE_Unbounded_Reclaim_Pool since it is unused.
25595 2004-10-26 Gary Dismukes <dismukes@gnat.com>
25597 * gnat1drv.adb: Suppress calling the back end when
25598 Frontend_Layout_On_Target is true.
25600 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25602 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
25603 Set_Read_Only): New subprograms.
25604 These new routines allow the user to set or unset the Owner execute
25605 and Owner write permission flags on a file.
25607 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
25608 GNAT.OS_Lib.Set_Executable instead of rolling our own.
25610 2004-10-26 Matthew Gingell <gingell@gnat.com>
25612 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
25614 2004-10-26 Pascal Obry <obry@gnat.com>
25616 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
25617 memory before the faulting page we properly test the process read
25618 access for this address using appropriate Win32 routine.
25619 (HPUX sections): guard with "__hpux__" instead of "hpux".
25621 2004-10-26 Robert Dewar <dewar@gnat.com>
25623 * lib-xref.adb (Generate_Reference): Don't complain about reference to
25624 entry parameter if pragma Unreferenced set, since we do not properly
25625 handle the case of multiple parameters.
25627 2004-10-26 Vincent Celier <celier@gnat.com>
25629 * prj-env.adb: (Contains_ALI_Files): New Boolean function
25630 (Ada_Objects_Path.Add): For a library project, add to the object path
25631 the library directory only if there is no object directory or if the
25632 library directory contains ALI files.
25633 (Set_Ada_Paths.Add.Recursive_Add): Ditto
25635 2004-10-26 Vincent Celier <celier@gnat.com>
25637 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
25638 extension of library projects.
25640 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
25641 path defaults to ".:<prefix>/lib/gnat".
25642 (Parse): For an extending all project, allow direct import of a project
25643 that is virtually extended.
25645 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
25646 the specified name is directly imported, return its ID. Otherwise, if
25647 an extension of this project is imported, return the ID of the
25650 2004-10-26 Robert Dewar <dewar@gnat.com>
25652 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
25653 (Sub3): New procedure, used by Scaled_Divide
25654 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
25655 correct more than one instance of failure to propagate carries
25657 (Double_Divide): Handle overflow case of largest negative number
25658 divided by minus one.
25660 * s-arit64.ads (Double_Divide): Document that overflow can occur in
25661 the case of a quotient value out of range.
25664 2004-10-26 Robert Dewar <dewar@gnat.com>
25666 * s-bitops.adb (Bit_Eq): Remove redundant check.
25668 * s-bitops.ads: Minor comment updates
25669 Change some occurrences of Address to System.Address
25671 * s-carsi8.ads: Fix minor cut-and-paste error in comments
25673 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25675 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
25676 accessibility check to prefix that is a protected operation.
25678 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25680 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
25681 empty, post message on stub.
25683 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25684 Javier Miranda <miranda@gnat.com>
25686 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
25687 current instance appears within a unit that is directly in the context
25689 Used to determine whether the body of the instance should be analyzed
25690 immediately after its spec, to make its subprogram bodies available
25691 for front-end inlining.
25692 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
25693 constraint is not allowed on the component type (AARM 12.5.3(3))
25695 2004-10-26 Cyrille Comar <comar@act-europe.fr>
25697 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
25698 'Storage_Pool): enhance, document & limit detection of non-sharable
25701 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
25703 * s-pooglo.ads: Add more documentation now that this pool is properly
25706 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25708 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
25709 or protected type with discriminants, do not constrain the
25710 corresponding record type if the subtype declaration has no
25711 discriminant constraints. This can be the case in source code, or in
25712 the subtype declaration created to rename an actual type within an
25715 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25717 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
25718 different kind of stub (possibly wrong name for file), do not check
25720 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
25721 includes call to some function that returns an unconstrained type, do
25724 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25726 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
25727 appear in the code for the main unit. Dependencies among units in the
25728 context of the main unit are established when those other units are
25729 compiled. Otherwise spurious elaboration constraints can generate
25730 incorrect elaboration circularities.
25732 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25733 Ed Schonberg <schonberg@gnat.com>
25735 * sem_util.adb (Is_Aliased_View): Defend against the case where this
25736 subprogram is called with a parameter that is not an object name. This
25737 situation arises for some cases of illegal code, which is diagnosed
25738 later, and in this case it is wrong to call Is_Aliased, as that might
25739 cause a compiler crash.
25740 (Explain_Limited_Type): Refine previous fix to include
25741 inherited components of derived types, to provide complete information.
25743 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
25744 is the prival for a protected object.
25745 It is necessary to mark this entity as a variable, in addition to
25746 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
25747 modified to avoid checking the Aliased flag on entities that are not
25748 objects. (Checking that flag for non-objects is erroneous and could
25749 lead to a compiler crash).
25751 2004-10-26 Robert Dewar <dewar@gnat.com>
25753 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
25754 X_Frac = 0.5, then we know that the number X must be positive.
25755 (Succ): Remove the same redundant test, and also fix the primary test
25756 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
25758 (Decompose): Add fuller comments to spec
25760 2004-10-26 Pascal Obry <obry@gnat.com>
25762 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
25763 validity (process must have read access). Set to 0 in all other cases.
25764 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
25765 violation on Win32.
25766 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
25767 segmentation violation.
25769 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
25771 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
25772 whose type is a constructed subtype of an aliased object with an
25773 unconstrained nominal subtype, convert the actual to the constructed
25774 subtype before taking its address.
25776 2004-10-26 Vincent Celier <celier@gnat.com>
25778 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
25779 (Is_Path_Name_Case_Sensitive): New function
25781 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
25782 (Base_Name, Simple_Name, Current_Directory, Compose,
25783 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
25786 2004-10-26 Cyrille Comar <comar@act-europe.fr>
25787 Vasiliy Fofanov <fofanov@act-europe.fr>
25788 Vincent Celier <celier@gnat.com>
25790 * gnat_ugn.texi: Generalize "finding memory problems" section into a
25791 "memory management issues" section and document some of the useful
25792 memory pools provided as part of the GNAT library.
25793 Remove "virtual" from declaration of A::method2 in
25794 the simple example of Ada/C++ mixed system.
25795 Library Projects may be virtually extended: their virtual extensions
25796 are not Library Projects.
25797 Added section on extending project hierarchies.
25799 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
25801 * adaint.c (__gnat_get_libraries_from_registry): Cast value
25803 (__gnat_portable_spawn): Remove const.
25805 * mingw32.h (MAXPATHLEN): Check for previous definition.
25807 2004-10-17 Matthias Klose <doko@debian.org>
25809 * gnatvsn.ads: Set gnat library version to 4.0.
25811 2004-10-05 Vincent Celier <celier@gnat.com>
25813 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
25815 2004-10-04 Laurent Guerby <laurent@guerby.net>
25818 * Makefile.in: Define and use RANLIB_FLAGS.
25820 2004-10-04 Pascal Obry <obry@gnat.com>
25822 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
25823 other x86 platforms).
25825 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
25827 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
25828 in general and triggers stack alignment adjustment for thread entry
25829 points on targets where this is necessary.
25831 2004-10-04 Bernard Banner <banner@gnat.com>
25834 * Makefile.in: Add section for powerpc linux
25835 Add variant i-vxwork-x86.ads
25837 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
25839 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
25841 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
25842 table registration calls when need be. Ensures no reference to the crt
25843 ctors symbol are issued in the SJLJ case, which avoids possible
25844 undefined symbol errors in the case of modules to be statically linked
25847 2004-10-04 Javier Miranda <miranda@gnat.com>
25849 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
25850 in-line the code corresponding to subprogram Analyze_Actuals. In
25851 addition, analyze the actuals only in case of subprogram call.
25853 2004-10-04 Ed Falis <falis@gnat.com>
25855 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
25857 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
25859 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
25860 in the documentation.
25862 2004-10-04 Robert Dewar <dewar@gnat.com>
25864 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
25866 (Analyze_Block_Statement): Add circuitry to detect following dead code
25867 (Check_Unreachable_Code): Handle case of block exit
25869 2004-10-04 Robert Dewar <dewar@gnat.com>
25871 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
25872 (XMatchD): Avoid warning for Logic_Error call
25874 2004-10-04 Robert Dewar <dewar@gnat.com>
25876 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
25877 consider expressions buried within a procedure actual to be an actual.
25878 This caused some blowups with uses of packed slices within a procedure
25881 2004-10-04 Robert Dewar <dewar@gnat.com>
25883 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
25884 longer need to be initialized to zero.
25885 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
25886 initialized to zero.
25888 * checks.adb (Expr_Known_Valid): Packed arrays are now always
25889 considered valid, even if the representation is modular. That's correct
25890 now that we no longer initialize packed modular arrays to zero.
25892 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
25893 suffixes. These are now documented as the only cases in which the
25894 debugger ignores outer records.
25895 Previously, the spec allowed arbitrary suffixes for this purpose.
25896 Change name of LJM to JM for packed array pad records
25897 Create separate section on packed array handling, and add a whole new
25898 set of comments to this section describing the situation with packed
25899 modular types and justification requirements depending on endianness.
25901 2004-10-04 Robert Dewar <dewar@gnat.com>
25903 * a-except.adb: Add a comment for last change

25912 * sem_util.ads: Minor comment update
25914 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25916 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
25917 Inline_Always when in Configurable_Run_Time mode.
25919 * sem_prag.adb (Process_Convention): If entity is an inherited
25920 subprogram, apply convention to parent subprogram if in same scope.
25921 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
25922 when in Configurable_Run_Time mode.
25924 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25926 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
25927 class_wide type after component list has been inherited.
25929 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25931 * sem_ch12.adb (Check_Generic_Actuals): New predicate
25932 Denotes_Previous_Actual, to handle properly the case of a private
25933 actual that is also the component type of a subsequent array actual.
25934 The visibility status of the first actual is not affected when the
25935 second is installed.
25936 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
25937 make fully recursive the treatment of formals of packages declared
25939 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
25940 the above on exit from an instantiation.
25941 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
25942 current instantiation which is now complete.
25943 (Analyze_Package_Instantiation): No instantiated body is needed if the
25944 main unit is generic. Efficient, and avoid anomalies when a instance
25945 appears in a package accessed through rtsfind.
25947 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25949 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
25950 do not generate a declaration for a temporary if the call is part of a
25951 library-level instantiation.
25953 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25955 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
25956 searching for a limited component to flag.
25958 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
25959 expansion of Input, to account for the fact that the implicit call
25960 generated by the attribute reference must freeze the user-defined
25961 stream subprogram. This is only relevant to 'Input, because it can
25962 appear in an object declaration, prior to the body of the subprogram.
25964 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
25965 expansion can proceed and further errors uncovered.
25966 (Minor clean up): Fix cases of using | instead of \ for continuation
25969 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
25971 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.

25974 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
25975 Use gcc_assert and gcc_unreachable.
25977 * decl.c (gnat_to_gnu_entity, case object): Check and process a
25978 specified alignment before validating size.
25979 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
25980 stripped-down declaration for the type of the inner field when making
25983 * utils.c (finish_record_type): Do not compute the size in units
25984 incrementally. Instead compute it once for the rep clause case.
25985 Use gcc_assert and gcc_unreachable.
25987 2004-10-04 Vincent Celier <celier@gnat.com>
25989 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
25991 (Is_Valid_Path_Name): Take '/' as a directory separator.
25993 2004-10-04 Vincent Celier <celier@gnat.com>
25995 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
25996 (Extended_Project) only if Extended_Project is defined, to avoid
25998 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
26000 (Parse_Single_Project): Ditto.
26002 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
26003 Add_To_Project_Path for virtual projects.
26005 2004-10-04 Vincent Celier <celier@gnat.com>
26007 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
26008 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
26009 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
26010 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
26011 parameter Options_2.
26013 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
26014 Build_Dynamic_Library with an empty Options_2.
26016 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
26019 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
26020 directory separator, if any.
26021 (Gprmake): Do not allow mains on the command line for library projects.
26022 Do not attempt to link when the project is a library project.
26023 (Library_Opts): New table to store Library_Options.
26024 (Build_Library): If Library_Options is specified, pass these options
26025 when building a shared library.
26027 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
26029 * s-tposen.adb (Service_Entry): The object must be always unlocked at
26030 the end of this procedure now that the unlock operation was inserted
26033 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
26035 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
26036 corresponding to the Preallocated_Stacks flags in System.
26037 (Get_Target_Parameters): Including the processing for
26038 Preallocated_Stacks.

26046 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
26047 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
26048 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
26049 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
26050 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
26051 used to signal whether the compiler creates the required stacks and
26052 descriptors for the different tasks (when True) or it is done by the
26053 underlying operating system at run time (when False).
26054 It is initially set to False in all targets.
26056 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
26057 if it is supported by the target.
26058 (Make_Task_Create_Call): Pass the stack address if it has been
26059 previously created. Otherwise pass a Null_Address.
26061 * snames.adb: Add _stack.
26063 * snames.ads: Add Name_uStack. Required to allow the expander to
26064 statically allocated task stacks.
26066 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
26067 Stack_Address argument.
26068 Check that its value is equal to Null_Address because this target does
26069 not support the static stack allocation.
26071 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
26073 * usage.adb: Change "pragma inline" to "pragma Inline" in information
26076 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
26078 * exp_dist.adb: Split declaration of asynchronous flag out of
26079 Add_RACW_Read_Attribute.
26080 Minor reformatting for better alignment with PolyORB version.
26081 Store the entity for the asynchronous flag of an RACW, rather than the
26082 expression, in the asynchronous flags table. This will allow this flag
26083 to be used in other subprograms beside Add_RACW_Read_Attribute.
26085 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
26087 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

26091 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
26092 sockets constant MSG_NOSIGNAL (Linux-specific).
26093 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
26094 all Send operations.
26095 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
26096 from trigerring SIGPIPE.
26097 Rename components to avoid clash with Ada 2005 possible reserved
26099 (Check_Selector): When the select system call returns with an error
26100 condition, propagate Socket_Error to the caller.

26110 instead do this at freeze time (we won't do it if there is an address
26112 Change "pragma inline" to "pragma Inline" in information and error
26114 Minor reformatting.
26116 * freeze.adb (Check_Address_Clause): Remove previous change, not the
26117 right way of doing things after all.
26118 (Freeze_Entity): For object, set Is_Public for imported entities
26119 unless there is an address clause present.
26121 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
26123 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
26124 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
26125 ensures proper handling of types with rep clauses, which might have
26126 their TYPE_SIZE set already.
26128 2004-09-21 Robert Dewar <dewar@gnat.com>
26130 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
26131 packed array types in both little- and big-endian cases. This change
26132 ensures that we no longer count on the unused bits being initialized
26133 for such types (and in particular ensures that equality testing will
26134 only read the relevant bits).
26135 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
26136 These changes mean that we no longer need to initialize small packed
26138 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
26139 optimization to an LJM field as to its parent field.
26141 * ada-tree.h, trans.c, utils.c, utils2.c:
26142 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
26144 2004-09-20 Jan Hubicka <jh@suse.cz>
26146 * utils.c (gnat_finalize): Remove.
26147 (end_subprog_body): Directly call cgraph_finalize_function;
26148 do not lower the nested functions.
26150 2004-09-20 Robert Dewar <dewar@gnat.com>
26153 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
26154 if an address clause is present, since that means that the Import
26157 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
26159 * 5tsystem.ads: Removed, no longer used.
26161 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
26162 Zack Weinberg <zack@codesourcery.com>
26164 * ada-tree.def: Use tree_code_class enumeration constants
26165 instead of code letters.
26166 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
26167 Update for new tree-class enumeration constants.

26183 an existing directory.
26184 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
26185 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
26186 Convert the result to File_Size.
26188 * prj.ads: (Project_Error): New exception
26190 * prj-attr.adb: Except in procedure Initialize, Fail comes from
26191 Prj.Com, not from Osint.
26192 (Attrs, Package_Attributes): Tables moved to private part of spec
26193 (Add_Attribute, Add_Unknown_Package): Moved to new child package
26195 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
26196 Prj.Project_Error after call to Fail.
26197 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
26198 Fail. Check that package name is not already in use.
26200 * prj-attr.ads: Comment updates to indicate that all subprograms may be
26201 used by tools, not only by the project manager, and to indicate that
26202 exception Prj.Prj_Error may be raised in case of problem.
26203 (Add_Unknown_Package, Add_Attribute): Moved to new child package
26205 (Attrs, Package_Attributes): Table instantiations moved from the body to
26206 the private part to be accessible from Prj.Attr.PM body.
26208 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
26209 from new package Prj.Attr.PM.
26210 (Parse_Attribute_Declaration): Call Add_Attribute from new package
26213 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
26215 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
26216 instead of Elaboration_Checks).
26218 * a-calend.adb: Minor reformatting

26258 2004-09-09 Jose Ruiz <ruiz@act-europe.fr>
26260 * gnat_ugn.texi: Add Detect_Blocking to the list of configuration
26261 pragmas recognized by GNAT.
26263 * gnat_rm.texi: Document pragma Detect_Blocking.
26265 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
26266 raise Program_Error if called from a protected operation.
26268 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
26269 the protected action nesting level.
26270 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
26271 protected action nesting level.
26272 (Unlock): When pragma Detect_Blocking is active decrease the protected
26273 action nesting level.
26275 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
26276 Protected_Action_Nesting.
26278 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
26279 Common_ATCB record. It contains the dynamic level of protected action
26280 nesting for each task. It is needed for checking whether potentially
26281 blocking operations are called from protected operations.
26282 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
26283 Detect_Blocking is active or not in the partition.
26285 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
26286 raise Program_Error if called from a protected operation.

26295 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
26296 raise Program_Error if called from a protected operation, and increase
26297 the protected action nesting level.
26298 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
26299 Program_Error if called from a protected operation, and increase the
26300 protected action nesting level.

26314 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
26315 protected action nesting level.
26317 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
26318 insertion of the statement raising Program_Error. The run time
26319 contains the required machinery for handling that.
26321 * sem_util.ads: Change comment associated to procedure
26322 Check_Potentially_Blocking_Operation.
26323 This procedure does not insert a call for raising the exception because
26324 that is currently done by the run time.
26326 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
26328 * init.c: Add the global variable __gl_detect_blocking that indicates
26329 whether pragma Detect_Blocking is active (1) or not (0). Needed for
26330 making the pragma available at run time.
26331 (__gnat_set_globals): Pass and update the detect_blocking parameter.
26333 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
26334 pragma Detect_Blocking is active.
26336 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
26338 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
26339 DB is found in the ali file. Any unit compiled with pragma
26340 Detect_Blocking active forces its effect in the whole partition.
26342 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
26343 Detect_Blocking is active and delay is called from a protected
26346 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
26347 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
26348 Detect_Blocking is active (0 otherwise).
26349 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
26350 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
26353 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
26355 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
26356 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
26359 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
26360 (Register_Receiving_Stub): Add Subp_Info formal parameter.
26361 Update API in placeholder implemetation of s-parint to reflect changes
26362 in distribution runtime library.
26364 * sem_ch3.adb (Expand_Derived_Record): Rename to
26365 Expand_Record_Extension.
26367 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
26368 primitive operations of potentially distributed object types that have
26369 non-controlling anonymous access formals.
26371 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
26373 New implementation of expansion for remote access-to-subprogram types,
26374 based on the RACW infrastructure.
26375 This version of sem_dist is compatible with PolyORB/DSA as well as
26378 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
26379 Asynchrronous that applies to a remote access-to-subprogram type, mark
26380 the underlying RACW type as asynchronous.
26382 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
26383 __gnat_using_gnu_linker to 1.
26385 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
26386 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
26387 GNAT.Perfect_Hash_Generators, and remove the empty

26392 * exp_ch3.adb (Expand_Derived_Record): Rename to
26393 Expand_Record_Extension.
26394 (Build_Record_Init_Proc.Build_Assignment): The default expression in
26395 a component declaration must remain attached at that point in the
26396 tree so New_Copy_Tree copies it if the enclosing record type is derived.
26397 It is therefore necessary to take a copy of the expression when building
26398 the corresponding assignment statement in the init proc.
26399 As a side effect, in the case of a derived record type, we now see the
26400 original expression, without any rewriting that could have occurred
26401 during expansion of the ancestor type's init proc, and we do not need
26402 to go back to Original_Node.
26404 * exp_ch3.ads (Expand_Derived_Record): Rename to
26405 Expand_Record_Extension.
26407 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
26408 Returns the RACW type used to implement a remote access-to-subprogram
26410 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
26411 New subprograms. Used to create a proxy tagged object for a remote
26412 subprogram. The proxy object is used as the designated object
26413 for RAS values on the same partition (unless All_Calls_Remote applies).
26414 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
26415 System.Partition_Interface.Get_Unique_Remote_Pointer.
26416 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
26417 Renamed from Add_RAS_*_Attribute.
26418 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
26420 New implementation of expansion for remote access-to-subprogram types,
26421 based on the RACW infrastructure.
26423 * exp_dist.ads (Copy_Specification): Update comment to note that this
26424 function can copy the specification from either a subprogram
26425 specification or an access-to-subprogram type definition.
26427 2004-09-09 Ed Schonberg <schonberg@gnat.com>
26429 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
26430 in an instance, between an explicit subprogram an one inherited from a
26431 type derived from an actual.
26433 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
26434 add a polling call if the subprogram is to be inlined by the back-end,
26435 to avoid repeated calls with multiple inlinings.
26437 * checks.adb (Apply_Alignment_Check): If the expression in the address
26438 clause is a call whose name is not a static entity (e.g. a dispatching
26439 call), treat as dynamic.
26441 2004-09-09 Robert Dewar <dewar@gnat.com>
26443 * g-trasym.ads: Minor reformatting
26445 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except
26446 packed arrays, since unused bits are expected to be zero for a

26451 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
26454 2004-09-09 Pascal Obry <obry@gnat.com>
26456 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
26457 enable map file generation. Add the right option to generate the map
26458 file if Map_File is set to True.
26460 * gnatdll.adb (Gen_Map_File): New variable.
26461 (Syntax): Add info about new -m (Map_File) option.
26462 (Parse_Command_Line): Add support for -m option.
26463 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

26466 2004-09-09 Laurent Pautet <pautet@act-europe.fr>
26468 * gnatls.adb: Add a very verbose mode -V. Such mode is required by the
26469 new gnatdist implementation.
26470 Define a subpackage isolating the output routines specific to this
26473 2004-09-09 Joel Brobecker <brobecker@gnat.com>
26475 * Makefile.rtl: (GNATRTL_NONTASKING_OBJS): Add g-dynhta.

26484 * opt.ads: Add Ada_Version_Runtime constant used to decide which
26485 version of the language is used to compile the run time.
26487 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
26489 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
26490 of variable length temporaries for function return now that the
26491 back-end and gigi support it.
26493 2004-09-01 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26495 * misc.c (gnat_print_type): Use TYPE_RM_SIZE_NUM.
26497 * trans.c (struct stmt_group): Delete field GLOBAL.

26715 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
26716 discriminants that rename those of the parent, recover names of

26748 returning C.int, to avoid using a derived boolean type.
26750 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

26779 ignore overflows on low and high bounds of an index to also account for
26780 differences in signedness between sizetype and gnu_index_subtype.

30698 complete assignment subtree which is now unnecessary, as the expansion
30699 of inlined call has been improved to preserve a consistent assignment

30701 after checks have been applied, or else unnecessary checks will

30907 * sem_ch3.adb (Access_Definition): In Ada 0Y the Can_Never_Be_Null
30908 attribute must be set only if specified by means of the null-excluding
30909 part. In addition, we must also propagate the access-constant attribute
30911 (Access_Subprogram_Declaration, Access_Type_Declaration,
30912 Analyze_Component_Declaration, Analyze_Object_Declaration,
30913 Array_Type_Declaration, Process_Discriminants,

30924 * sem_ch6.adb (Process_Formals): Carry out some static checks.
30925 (Set_Actual_Subtypes): Generate null-excluding subtype if the
30926 null-excluding part was present; it is not required to be done here in
30927 case of anonymous access types.
30928 (Set_Formal_Mode): Ada 0Y allows anonymous access to have the null
30931 * sem_res.adb (Resolve_Actuals): Carry out some static check
30932 (Resolve_Null): Allow null in anonymous access
30934 * sinfo.adb: New subprogram Null_Exclusion_Present
30935 All_Present and Constant_Present available on access_definition nodes
30937 * sinfo.ads: New flag Null_Exclusion_Present on subtype_declaration,
30938 object_declaration, derived_type_definition, component_definition,
30939 discriminant_specification, access_to_object_definition,

30958 * sem_ch12.adb: Add comment for previous change
30960 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
30962 * osint.adb (Executable_Prefix): Set Exec_Name to the current
30963 executable name when not initialized. Otherwise, use its current value.
30965 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
30966 initialize it to another executable name than the current one. This
30967 allows to configure paths for an executable name (gnatmake) different
30968 from the current one (gnatdist).
30970 2004-03-29 Ed Schonberg <schonberg@gnat.com>
30972 * exp_ch6.adb (Expand_Call): A call to a function declared in the
30973 current unit cannot be inlined if it appears in the body of a withed
30974 unit, to avoid order of elaboration problems in gigi.
30976 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
30977 information for protected (wrapper) operation as well, to simplify gdb
30980 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
30981 protected body, indicate that the entity for the generated spec comes
30982 from source, to ensure that references are properly generated for it.
30983 (Build_Body_To_Inline): Do not inline a function that returns a
30986 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
30987 apply convention to homonyms that are declared explicitly.
30989 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
30990 that renames an equality operator and the operands are overloaded,
30991 resolve them with the declared formal types, before rewriting as an
30994 2004-03-29 GNAT Script <nobody@gnat.com>
30996 * Make-lang.in: Makefile automatically updated
30998 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
31000 * memtrack.adb: Log realloc calls, which are treated as free followed
31003 2004-03-25 Vincent Celier <celier@gnat.com>
31005 * prj-makr.adb (Process_Directories): Detect when a file contains
31006 several units. Do not include such files in the config pragmas or

31015 resolve links when computing the display names.
31017 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
31019 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
31020 attribute reference does not denote a subtype, it can be any
31021 expression that has a classwide type, potentially after an implicit
31022 dereference. In particular, the prefix can be a view conversion for
31023 a classwide type (for which Is_Object_Reference holds), but it can
31024 also be a value conversion for an access-to-classwide type. In the
31025 latter case, there is an implicit dereference, and the original node
31026 for the prefix does not verify Is_Object_Reference.
31028 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
31029 conversion of a discriminant-dependent component of a mutable object
31032 2004-03-25 Ed Schonberg <schonberg@gnat.com>
31034 * freeze.adb (Freeze_Entity): When an inherited subprogram is
31035 inherited, has convention C, and has unconstrained array parameters,
31036 place the corresponding warning on the derived type declaration rather
31037 than the original subprogram.
31039 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
31040 indication on renaming declaration, if formal has a box and actual
31043 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
31044 determine whether to generate an implicit or explicit reference to
31045 the renamed entity.
31047 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
31048 subprogram renaming comes from a defaulted formal subprogram in an
31051 2004-03-25 Gary Dismukes <dismukes@gnat.com>
31053 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
31054 value expressions to ensure that calls within a component definition
31055 will be checked (since those are evaluated during the record type's
31058 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
31060 * s-tpobop.adb: Code clean up:
31061 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

31079 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
31080 Has_RACW, Is_Generic, etc.)
31081 (Output_Object, Gnatls): Take into account ALI files not attached to
31084 2004-03-22 Vincent Celier <celier@gnat.com>

31101 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
31102 case when the source contains only comments.
31104 2004-03-22 Ed Schonberg <schonberg@gnat.com>
31106 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
31107 declaration for a child subprogram body that acts as a spec, indicate
31108 that the entity in the declaration needs debugging information.
31110 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
31111 full view if the subtype is created for a constrained record component;
31112 gigi has enough information to construct the record, and there is no
31113 place in the tree for the declaration.
31115 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
31116 serial number for the dummy body that is built for analysis, to avoid
31117 inconsistencies in the generation of internal names when compiling
31120 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
31122 * sem_util.adb (Is_Object_Reference): A view conversion denotes an

31148 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
31149 gnat_ug_wnt.texi: Regenerate.
31151 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
31153 * ada-tree.h: Update copyright notice.
31154 Minor reformatting.
31156 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
31158 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
31159 as regular exception objects and not as mere integers representing the
31160 condition code. The latter approach required some dynamics to mask off
31161 severity bits, which did not fit well into the GCC table based model.
31162 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
31163 exception data objects. We don't it and it would conflict with the other
31164 external symbol we have to generate for such exceptions.
31166 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
31167 the special code for VMS exceptions, since these are now represented
31168 as regular exceptions objects.
31170 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
31172 * decl.c (debug_no_type_hash): Remove.

31174 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
31176 2004-03-19 Laurent Guerby <laurent@guerby.net>
31178 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
31179 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
31181 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
31183 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
31184 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
31185 (TYPE_RM_SIZE_INT): Directly use type.values.
31186 (TREE_LOOP_ID): Clean up check.
31187 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
31188 TYPE_VALUES, not TYPE_FIELDS.
31189 * trans.c (convert_with_check): Delay access of bounds of basetype
31190 until sure is numeric.

31198 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
31199 Specific.Set instead of direct call to e.g pthread_setspecific.
31201 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
31203 * adaint.c: Update comments.
31205 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
31206 GNATLIB_SHARED for FreeBSD.
31208 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
31210 * init.c [VxWorks]: Do not fix the stack size for the environment task.
31211 When needed (stack checking) the stack size is retrieved
31212 from the VxWorks kernel.
31214 * Makefile.in: Flag -nostdinc is required when building the run time
31215 for avoiding looking for files in the base compiler.
31216 Add the VxWorks specific version of the package body for
31217 System.Stack_checking.Operations (5zstchop.adb).
31219 * Make-lang.in: Add the object file for
31220 System.Stack_Checking.Operations.
31222 * Makefile.rtl: Add object file for the package
31223 System.Stack_Checking.Operations.
31225 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
31227 * s-stache.ads, s-stache.adb: Move the operations related to stack
31228 checking from this package to package System.Stack_Checking.Operations.
31229 This way, stack checking operations are only linked in the final
31230 executable when using the -fstack-check flag.
31232 2004-03-18 Doug Rupp <rupp@gnat.com>
31234 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
31237 * 5qsystem.ads, 5xcrtl.ads: New files.

31243 * prj-env.adb (Source_Paths, Object_Paths): New tables.
31244 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
31245 the procedures Add_To_Path_File.
31246 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
31247 making sure that each directory is present only once and, for object
31248 dirs, when a directory already present is added, the duplicate is
31249 removed and the directory is always put as the last in the table.
31250 Write the path files at the end of these accumulations.
31252 * prj-nmsc.adb (Record_Source): Add source file name in hash table
31253 Files_Htable for all sources.
31255 * prj-proc.adb (Process): Remove restrictions between not directly
31256 related extending projects.
31258 2004-03-18 Emmanuel Briot <briot@act-europe.fr>

31264 parameter Trusted_Mode.
31266 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
31268 * scn.adb (Determine_License): Take into account a degenerated case
31269 when the source contains only comments.
31271 2004-03-18 Ed Schonberg <schonberg@gnat.com>
31273 * sem_warn.adb (Check_References): For a warning on a selected
31274 component that does not come from source, locate an uninitialized
31275 component of the record type to produce a more precise error message.
31277 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
31279 * 3zsoccon.ads: Fix multicast options.
31281 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
31284 2004-03-15 Robert Dewar <dewar@gnat.com>
31286 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
31287 pragma used for a private type.
31289 * lib-xref.adb (Generate_Reference): Do not generate warning if
31290 reference is in a different unit from the pragma Unreferenced.
31292 * 5vtpopde.adb: Minor reformatting
31293 Fix casing of To_Task_ID
31295 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
31296 flag if we have an unchecked conversion to an access type in the same
31299 2004-03-15 Geert Bosch <bosch@gnat.com>
31301 * a-ngcoty.adb (Modulus): In alternate formula for large real or
31302 imaginary parts, use Double precision throughout.
31304 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
31305 we want to be able to compile run-time with -gnata for testing, but
31306 this may also be instantiated in user code that is compiled with -gnata.
31308 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
31310 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
31311 codes. Having a separate type for this is useful to enforce consistency
31312 throughout the various run-time units.
31313 (Exception_Data): Use Exception_Code for Import_Code.
31315 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
31316 Natural and Integer in various places.

31318 with the severity bits masked off.
31319 (Register_VMS_Exception): Handle the additional exception data pointer
31322 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
31323 component, now reflected by an exported accessor.
31324 (is_handled_by): New routine to compute whether the propagated
31325 occurrence matches some handler choice specification. Extracted out of
31326 get_action_description_for, and expanded to take care of the VMS
31328 (get_action_description_for): Use is_handled_by instead of an explicit
31329 complex condition to decide if the current choice at hand catches the
31330 propagated occurrence.
31332 * raise.h (Exception_Code): New type for C.
31334 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
31335 System.Standard_Library.Exception_Code, to allow references from the
31336 pragma import/export expander.
31338 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
31339 New accessors to allow easy access to GNAT exception data
31341 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
31342 redundant Handled_By_Others component, helper for the personality
31343 routine which will now be able to call the appropriate exception data
31346 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
31347 component of Standard_Exception_Type to be the closest possible to
31348 Exception_Code in System.Standard_Library, that we cannot get at this
31349 point. Expand a ??? comment to notify that this type node should
31350 probably be rewritten later on.
31352 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
31353 registration call to include a pointer to the exception object in the
31356 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
31357 instead of int and explicit bitmasks.
31359 2004-03-15 Vincent Celier <celier@gnat.com>
31361 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
31362 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
31364 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
31365 longer needed now that it is in the spec of
31366 System.Tasking.Task_Attributes.
31368 * adaint.h, adaint.c: (__gnat_create_output_file): New function
31370 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
31372 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
31374 * make.adb (Gnatmake): Do not check the executable suffix; it is being
31375 taken care of in Scan_Make_Arg.
31376 (Scan_Make_Arg): Add the executable suffix only if the argument
31377 following -o, in canonical case, does not end with the executable
31378 suffix. When in verbose mode and executable file name does not end
31379 with executable suffix, output the executable name, in canonical case.
31381 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
31382 to avoid warnings when instantiating Ada.Task_Attributes.
31385 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
31386 in the correct order.
31388 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
31389 redirect standard output and error to a file for the invocation of the
31390 compiler, then read the file.
31392 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
31393 directory, instead of the Value.
31394 (Find_Source_Dirs): Remove useless code & comments.
31396 2004-03-15 Ed Schonberg <schonberg@gnat.com>
31398 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
31399 tagged type is inherited, and the parent operation is not frozen yet,
31400 force generation of a freeze node for the inherited operation, so the
31401 corresponding dispatch entry is properly initialized.
31402 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
31403 when looking for user-defined equality operation.
31405 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
31406 boolean when locating primitive equality of tagged component.
31408 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
31409 bit-aligned field and the right-hand side a string literal, introduce
31410 a temporary before expanding assignment into a loop.

32352 checks for bitfield creation are triggered.
32353 (finish_record_type): During last pass over the fields, clear
32354 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

32813 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
32814 N_String_Literal node always references an E_String_Literal_Subtype
32815 entity. This may not be true in the future.
32816 (Possible_Bit_Aligned_Component): Move processing of
32817 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
32819 * exp_ch6.adb (Expand_Thread_Body): Pick up

32824 (Type_May_Have_Bit_Aligned_Components): New function.

32864 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
32865 ineffective elaborate all pragmas on non-visible packages (this
32866 happened when a renamed subprogram was called). Now the elaborate all
32867 always goes on the package containing the renaming rather than the one
32868 containing the renamed subprogram.
32870 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
32871 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

32896 * make.adb (Gnatmake): Special process for files to compile/check when
32897 -B is specified. Fail when there are only foreign mains in attribute

32932 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
32933 all attributes, including read-only attribute.

32972 checked when limited aggregates are implemented.

32975 pure, emit warning.

33085 * 5zinit.adb: Clean up.
33087 * 5zintman.adb (Notify_Exception): replaced case statement with a call
33088 to __gnat_map_signal, imported from init.c to support
33089 signal -> exception mappings that depend on the vxWorks version.
33092 Created and exported __gnat_map_signal to support signal -> exception
33093 mapping that is dependent on the VxWorks version.

33126 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
33127 bounds of a loop, create a separate block in order to generate proper
33128 cleanup actions to prevent memory leaks.
33130 * sem_res.adb (Resolve_Call): After a call to
33131 Establish_Transient_Scope, the call may be rewritten and relocated, in

33150 2003-12-08 Robert Dewar <dewar@gnat.com>
33152 * 7sintman.adb: Minor reformatting
33154 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
33155 standard linker options to get standard libraries linked. We now plan
33156 to provide dummy versions of these libraries to match the appropriate
33157 configurable run-time (e.g. if a library is not needed at all, provide
33158 a dummy empty library).
33160 * targparm.ads: Configurable_Run_Time mode no longer affects linker
33161 options (-L parameters and standard libraries). What we plan to do is
33162 to provide dummy libraries where the libraries are not required.
33164 * gnatbind.adb: Minor comment improvement
33166 2003-12-08 Javier Miranda <miranda@gnat.com>
33168 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

33176 of aggregate with default initialized components.
33177 (Has_Default_Init_Comps): Improve implementation to recursively check
33178 all the present expressions.
33180 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
33181 to indicate that the initialization call corresponds to a
33182 default-initialized component of an aggregate.
33183 In case of default initialized aggregate with tasks this parameter is
33184 used to generate a null string (this is just a workaround that must be
33185 improved later). In case of discriminants, this parameter is used to
33186 generate a selected component node that gives access to the discriminant
33189 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
33190 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
33191 allocated aggregates with default-initialized components.
33193 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
33194 the box notation is used in positional aggregates.

33236 Process nodes N_Comment.
33238 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
33239 without comments and there are some comments, set the flag
33240 Unkept_Comments to True.
33241 (Scan): If there are comments, set the flag Unkept_Comments to True and
33242 clear the comments.

33282 Correct typo in comment
33283 (Resolve_Aggregate): In case of array aggregates set the estimated
33284 type of the aggregate before calling resolve. This is needed to know
33285 the name of the corresponding IP in case of limited array aggregates.
33286 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
33287 in case of default initialized array components.

33309 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
33310 they are automatically generated by Make-lang.in and cause nothing but
33311 maintenance troubles.
33313 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
33315 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

33329 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
33330 to ensure that the kernel fills in the interrupted context structure
33331 before calling a signal handler, which is necessary to be able to
33332 unwind past it. Update the copyright notice.
33334 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
33336 * a-elchha.ads: New file.

33423 2003-12-03 Ed Schonberg <schonberg@gnat.com>
33426 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
33427 is legal in an instance, because legality is cheched in the template.

33431 appplied to an unchecked conversion of a formal parameter.
33434 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

33448 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
33449 so that the debugger can reliably access the value of the parameter,

36356 2002-09-23 Zack Weinberg <zack@codesourcery.com>
36358 * Make-lang.in (EXTRA_GNATBIND_OBJS): Add version.o.
36359 * Makefile.in (TOOLS_LIBS): Add ../../version.o.
36360 * gnatvsn.ads: Gnat_Version_String is now a function.
36361 * gnatvsn.adb: New file. When asked for Gnat_Version_String,
36362 copy the C version_string into a String and return it.
36363 * gnatcmd.adb, gnatkr.adb, gnatlbr.adb, gnatlink.adb,
36364 gnatls.adb,gnatmake.adb, gnatprep.adb, gnatpsta.adb:
36365 Remove pragma Ident (Gnat_Version_String). If this was the
36366 sole use of package Gnatvsn, remove the with statement too.

36978 2002-01-30 Richard Henderson <rth@redhat.com>
36980 * trans.c (tree_transform) [N_Loop_Statement]: Use
36981 expand_exit_loop_top_cond.

36999 (general) Add @./@: where approriate, and two spaces after the
37000 full stop at the end of a sentence. Use @samp markup when
37001 referring concrete lexical entities (keywords, attribute names
37002 etc.), and @syntax for ARM grammar elements. Use @r for English

37018 function approach did not work well because of a side effect (the
37019 function call could reallocate the table which was being indexed
37020 using its result). Fixes ada/4851.

37081 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
37082 need to force universal inlining for these cases.
37084 2001-12-19 Arnaud Charlet <charlet@gnat.com>
37086 * s-taprob.adb: Minor clean ups so that this unit can be used in

37113 the argument of an initialization procedure.
37115 * trans.c (tree_transform, case of arithmetic operators): If result
37116 type is private, the gnu_type is the base type of the full view,
37117 given that the full view itself may be a subtype.

37387 2001-12-17 Laurent Pautet <pautet@gnat.com>
37390 Fix comment of Shutdown_Socket and Close_Socket. These functions
37391 should not fail silently because if they are called twice, this
37392 probably means that there is a race condition in the user program.
37393 Anyway, this behaviour is consistent with the rest of this unit.

37548 reference nodes, since this field is used in such nodes.

38729 instead of the previous simple checksum algorithm.
38730 (Time_Stamp_Mismatch): use CRC_Match for comparison.
38731 (Set_Source_Table): idem.
38734 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
38735 instead of simple checksum.
38736 (CRC_Match): new function.
38737 (CRC_Error): new constant.
38739 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
38740 a CRC now and not a simple checksum. A CRC uses lower-case hex
38741 letters, fixes ambiguity in parsing.
38743 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
38744 is what this variable will store.
38746 * bcheck.adb: Change reference to chechsum in comments by CRC.
38747 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
38748 rename All_Checksum_Match to All_CRC_Match. Change due to API
38749 renaming since now GNAT does not use a simple checksum but a
38750 CRC using GNAT.CRC32.
38752 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
38753 now and not anymore a simple checksum.

38790 Update comments for the CRC.
38792 * types.adb (Hex): Use lowercase for the letter part.
38794 * types.ads (Get_Hex_String): Returns the hexadecimal representation
38795 for a word. This is currently used only for CRC. In previous version,
38796 the checksum was using a representation with all letter being
38797 upper-case. With the new implementation (using CRC) we do not remove
38798 the 32th bit of the CRC, so we can have an upper-case starting letter
38799 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
38800 It is ambigous since the CRC was optional and could be followed by
38801 options like EB, EE. So now this routines uses lower-case letter for
38802 the hexadecimal representation. Strange enough only lower case letters
38803 where checked in Scan_ALI (even if this was not a possible case).
38805 * gnatvsn.ads (Library_Version): changed to 3.15a.
38807 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
38810 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
38813 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
38814 Add 2001 to copyright notice
38815 (Accumulate_Checksum): Modify to use System.CRC32.
38817 * ali-util.ads: Redo changes of previous revision to continue to use
38818 the word Checksum. Add 2001 to copyright notice.
38820 * ali.adb: Undo some of previous changes, not needed.
38821 Keep the change for lower case letters in the checksum.
38823 * ali.ads: Undo previous change not needed.
38825 * bcheck.adb: Undo most of previous change, not needed.
38826 But do use Checksums_Match for checksum comparison.

38829 But do use Checksums_Match for comparing checksums.
38831 * lib-load.adb: Undo previous change, not needed.
38833 * lib-writ.adb: Undo previous change, not needed.

38853 * sinput.adb: Undo previous change, not needed.
38855 * sinput-l.adb: Undo previous change, not needed.
38857 * sinput.ads: Undo previous change, not needed. Keep only comment
38858 on new checksum algorithm
