2015-05-25 Javier Miranda <miranda@adacore.com> * einfo.ads, einfo.adb (Has_Out_Or_In_Out_Parameter): This attribute is now present in subprograms, generic subprograms, entries and entry families. * sem_ch6.adb (Set_Formal_Mode): Set As_Out_Or_In_Out_Parameter on entries, entry families, subprograms and generic subprograms. * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration): Minor code reorganization to ensure that the Ekind attribute of the subprogram entity is set before its formals are processed. Required to allow the use of the attribute Has_Out_Or_In_Out_Parameter on the subprogram entity. * sem_aggr.adb (Resolve_Aggregate, Resolve_Extension_Aggregate): Perform the check on writable actuals only if the value of some component of the aggregate involves calling a function with out-mode parameters. (Resolve_Record_Aggregate): Propagate the Check_Actuals flag to the internally built aggregate. * sem_ch3.adb (Build_Derived_Record_Type, Record_Type_Declaration): Perform the check on writable actuals only if the initialization of some component involves calling a function with out-mode parameters. * sem_ch4.adb (Analyze_Arithmetic_Op, Analyze_Comparison_Op, Analyze_Equality_Op, Analyze_Logical_Op, Analyze_Membership_Op, Analyze_Range): Check writable actuals only if the subtrees have a call to a function with out-mode parameters (Analyze_Call.Check_Writable_Actuals): New subprogram. If the call has out or in-out parameters then mark its outermost enclosing construct as a node on which the writable actuals check must be performed. (Analyze_Call): Check if the flag must be set and if the outermost enclosing construct. * sem_util.adb (Check_Function_Writable_Actuals): Code cleanup and reorganization. We skip processing aggregate discriminants since their precise analysis involves two phases traversal. * sem_res.adb (Resolve_Actuals, Resolve_Arithmetic_Op, Resolve_Logical_Op, Resolve_Membership_Op): Remove call to check_writable_actuals.

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.
