+
+ * exp_disp.adb (Make_DT, Make_Secondary_DT, Make_Tags): Avoid
+ generating dispatch tables of locally defined tagged types statically.
+ Remove implicit if-statement that is no longer required.
+ (Expand_Dispatching_Call): If this is a call to an instance of the
+ generic dispatching constructor, the type of the first argument may be
+ a subtype of Tag, so always use the base type to recognize this case.
+
+2008-05-20 Thomas Quinot <quinot@adacore.com>
+
+ * exp_dist.adb
+ (GARLIC_Support.Add_RACW_Read_Attribute): When a zero value is received,
+ and the RACW is null-excluding, raise CONSTRAINT_ERROR instead of
+ assigning NULL into the result, to avoid a spurious warning.
+ (Add_RACW_Features, case Same_Scope): Add assertion that designated type
+ is not frozen.
+ (Add_Stub_Type): Set entity flag Is_RACW_Stub_Type on generated stub
+ type.
+ (Build_From_Any_Function, Build_To_Any_Function,
+ Build_TypeCode_Function): For a type that has user-specified stream
+ attributes, use an opaque sequence of octets as the representation.
+
+2008-05-20 Kevin Pouget <pouget@adacore.com>
+
+ * exp_smem.ads, exp_smem.adb: Construction of access and assign
+ routines has been replaced by an instantiation of
+ System.Shared_Storage.Shared_Var_Procs generic package, while expanding
+ shared variable declaration.
+ Calls to access and assign routines have been replaced by calls to
+ Read/Write routines of System.Shared_Storage.Shared_Var_Procs
+ instantiated package.
+
+ * rtsfind.ads: RE_Shared_Var_Procs entry has been added in RE_Unit_Table
+ It identifies the new generic package added in s-shasto.
+
+ * s-shasto.adb, s-shasto.ads: A new generic package has been added, it
+ is instantiated for each shared passive variable. It provides
+ supporting procedures called upon each read or write access by the
+ expanded code.
+
+ * sem_attr.adb:
+ For this runtime unit (always compiled in GNAT mode), we allow
+ stream attributes references for limited types for the case where
+ shared passive objects are implemented using stream attributes,
+ which is the default in GNAT's persistent storage implementation.
+
+2008-05-20 Ed Schonberg <schonberg@adacore.com>
+
+ * freeze.adb
+ (Freeze_Enumeration_Type): For a subtype that inherits a foreign
+ convention from its base type, do not set the type to that of integer,
+ because it may inherit a size clause.
+ Warn on a size clause with a size different
+ from that of Integer, if the type has convention C.
+
+2008-05-20 Vincent Celier <celier@adacore.com>
+
+ * gnatname.adb
+ (Scan_Args): Rewrite to take into account new switch --and to separate

+
+ * par-ch3.adb
+ (P_Access_Definition): Change the error message when parsing "access

+ in 05 mode only to discover that anonymous access types are not allowed
+ to have "all".
+
+2008-05-20 Hristian Kirtchev <kirtchev@adacore.com>
+
+ * par-ch9.adb
+ (P_Protected): Update the error message on missing "-gnat05" switch when

+
+ * sem_cat.adb
+ (Set_Categorization_From_Scope): Do not set In_Remote_Types unless in
+ the visible part of the spec of a remote types unit.
+ (Validate_Remote_Access_Object_Type_Declaration):
+ New local subprogram Is_Valid_Remote_Object_Type, replaces
+ Is_Recursively_Limited_Private.
+ (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
+ non-controlling formals (and the return type, even though this is not
+ explicit in the standard) must support external streaming.
+ (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
+ as above for of RAS types and RCI subprograms. (The return type is not
+ checked yet).
+ Update comments related to RACWs designating limited interfaces per
+ ARG ruling on AI05-060.
+
+ * sem_util.ads, sem_util.adb
+ (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
+ Is_Remote_Call_Interface to identify RACW types in a stable and
+ consistent way. We used to rely in this predicate on the privateness of
+ the designated type and its ancestors, but depending on the currently
+ visible private parts, this caused false negatives. We now uniformly
+ rely on checks made at the point where the RACW type is declared.
+ (Inspect_Deferred_Constant_Completion): Moved from Sem_Ch7.

+
+ * sem_ch3.adb
+ (Analyze_Object_Declaration): Fix over-conservative condition
+ restricting use of predefined assignment with tagged types that have
+ convention CPP.
+ (Analyze_Object_Declaration): Relax the check regarding deferred
+ constants declared in scopes other than packages since they can be
+ completed with pragma Import.
+ Add missing escaping of all-caps word 'CPP' in error messages.
+ (Build_Discriminated_Subtype): Do not inherit representation clauses
+ from parent type if subtype already carries them, because they are
+ inherited earlier during derivation and already include those that may
+ come from a partial view.
+
+ * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):

+ * sem_ch4.adb
+ (Try_Indexed_Call): Handle properly a construct of the form F(S) where
+ F is a parameterless function that returns an array, and S is a subtype
+ mark.
+ (Analyze_Call): Insert dereference when the prefix is a parameterless
+ function that returns an access to subprogram and the call has
+ parameters.
+ Reject a non-overloaded call whose name resolves to denote
+ a primitive operation of the stub type generated to support a remote
+ access-to-class-wide type.

+
+ * sem_ch8.adb
+ (Note_Redundant_Use): Diagnose a redundant use within a subprogram body

+ (Analyze_Subprogram_Renaming): A renaming_as_body is legal if it is
+ created for a stream attribute of an abstract type or interface type.

+
+ * sem_type.adb
+ (Add_One_Interp): Ignore any interpretation that is a primitive
+ operation of an RACW stub type (these primitives are only executed
+ through dispatching, never through static calls).
+ (Collect_Interps): When only one interpretation has been found, set N's
+ Entity and Etype to that interpretation, otherwise Entity and Etype may
+ still refer to an interpretation that was ignored by Add_One_Interp,
+ in which case would end up with being marked as not overloaded but with
+ an Entity attribute not pointing to its (unique) correct interpretation.
