2017-09-29 Bob Duff <duff@adacore.com> * exp_ch6.adb (Expand_Call_Helper): Handle case of build-in-place functions returning nonlimited types. Allow for qualified expressions and type conversions. (Expand_N_Extended_Return_Statement): Correct the computation of Func_Bod to allow for child units. (Expand_Simple_Function_Return): Remove assumption that b-i-p implies limited (initialization of In_Place_Expansion), and implies >= Ada 2005. (Is_Build_In_Place_Result_Type): New function to accompany Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because sometimes we just have the type on our hands, not the function. For now, does the same thing as the old version, so build-in-place is disabled for nonlimited types, except that you can use -gnatd.9 to enable it. * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to accompany Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because sometimes we just have the type on our hands, not the function. (Make_Build_In_Place_Call_In_...): Handle nonlimited build-in-place cases. (Make_Build_In_Place_Call_In_Object_Declaration): Remove the questionable code at the end that was setting the Etype. * exp_aggr.adb (Is_Build_In_Place_Aggregate_Return): New function to determine whether "return (...agg...);" is returning from a build-in-place function. (Initialize_Ctrl_Array_Component, Initialize_Ctrl_Record_Component): Remove assumption that b-i-p implies limited (initialization of In_Place_Expansion). (Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in an unchecked conversion. Add assertions. (Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for secondary stack here, just because the type needs finalization. That code is obsolete. (Convert_To_Assignments): Only set Unc_Decl if Nkind (N) = N_Aggregate. For "return (...agg...);" don't assume b-i-p implies limited. Needs_Finalization does not imply secondary stack. (Expand_Array_Aggregate): Named notation. Reverse the sense of Component_OK_For_Backend -- more readability with fewer double negatives. * exp_attr.adb (Expand_N_Attribute_Reference): Remove assumptions that b-i-p implies >= Ada 2005. * exp_ch3.adb (Expand_N_Object_Declaration): Remove assumptions that b-i-p implies >= Ada 2005. Remove Adjust if we're building the return object of an extended return statement in place. * exp_ch4.adb (Expand_Allocator_Expression, Expand_N_Indexed_Component, Expand_N_Selected_Component, Expand_N_Slice): Remove assumptions that b-i-p implies >= Ada 2005. * exp_ch5.adb (Expand_N_Assignment_Statement): Remove assumption that b-i-p implies >= Ada 2005. * exp_ch7.adb: Comment fix. * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): Remove assumptions that b-i-p implies >= Ada 2005. * exp_disp.adb (Expand_Interface_Actuals): Remove assumptions that b-i-p implies >= Ada 2005. * exp_util.adb (Build_Allocate_Deallocate_Proc): Look at Storage_Pool (Expr), in case Pool_Id is not set. (Initialized_By_Aliased_BIP_Func_Call): Handle case where the call is qualified or converted. (Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name (Param)) = N_Identifier; that's all it could be. * sinfo.ads: Comment fixes. * snames.ads-tmpl: Comment fixes. * debug.adb: Add flag gnatd.9, to enable the build-in-place machinery.

README
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.
