2017-10-20 Bob Duff <duff@adacore.com> * sinfo.ads, sinfo.adb (Alloc_For_BIP_Return): New flag to indicate that an allocator came from a b-i-p return statement. * exp_ch4.adb (Expand_Allocator_Expression): Avoid adjusting the return object of a nonlimited build-in-place function call. * exp_ch6.adb (Expand_N_Extended_Return_Statement): Set the Alloc_For_BIP_Return flag on generated allocators. * sem_ch5.adb (Analyze_Assignment): Move Assert to where it can't fail. If the N_Assignment_Statement has been transformed into something else, then Should_Transform_BIP_Assignment won't work. * exp_ch3.adb (Expand_N_Object_Declaration): A previous revision said, "Remove Adjust if we're building the return object of an extended return statement in place." Back out that part of the change, because the Alloc_For_BIP_Return flag is now used for that. From-SVN: r253940
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.
