2017-04-25 Hristian Kirtchev <kirtchev@adacore.com> * elists.ads, elists.adb (Prepend_Unique_Elmt): New routine. * exp_ch3.adb (Freeze_Type): Signal the DIC body is created for the purposes of freezing. * exp_util.adb Update the documentation and structure of the type map used in class-wide semantics of assertion expressions. (Add_Inherited_Tagged_DIC): There is really no need to preanalyze and resolve the triaged expression because all substitutions refer to the proper entities. Update the replacement of references. (Build_DIC_Procedure_Body): Add formal parameter For_Freeze. Add local variable Build_Body. Inherited DIC pragmas are now only processed when freezing occurs. Build a body only when one is needed. (Entity_Hash): Removed. (Map_Types): New routine. (Replace_Object_And_Primitive_References): Removed. (Replace_References): New routine. (Replace_Type_References): Moved to the library level of Exp_Util. (Type_Map_Hash): New routine. (Update_Primitives_Mapping): Update the mapping call. (Update_Primitives_Mapping_Of_Types): Removed. * exp_util.ads (Build_DIC_Procedure_Body): Add formal parameter For_Freeze and update the comment on usage. (Map_Types): New routine. (Replace_References): New routine. (Replace_Type_References): Moved to the library level of Exp_Util. (Update_Primitives_Mapping_Of_Types): Removed. * sem_ch7.adb (Preserve_Full_Attributes): Propagate the DIC properties of the private type to the full view in case the full view derives from a parent type and inherits a DIC pragma. * sem_prag.adb (Analyze_Pragma): Guard against a case where a DIC pragma is placed at the top of a declarative region. 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek> * a-tasatt.adb: Complete previous change and use an unsigned int to avoid overflow checks. 2017-04-25 Ed Schonberg <schonberg@adacore.com> * sem_attr.adb (Analyze_Attribute, case 'Access): Specialize the error message when the attribute reference is an actual in a call to a subprogram inherited from a generic formal type with unknown discriminants, which makes the subprogram and its formal parameters intrinsic (see RM 6.3.1 (8) and (13)).

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
