PR middle-end/65958 * gimplify.c (struct gimplify_ctx): Turn boolean fields into 1-bit fields, add keep_stack and reorder them. (gimplify_bind_expr): Save gimplify_ctxp->keep_stack on entry then set it to false. Do not insert a stack save/restore pair if it has been set to true by the gimplification of the statements. Restore it to the saved value on exit if it is still false. (gimplify_vla_decl): Do not set gimplify_ctxp->save_stack here. (gimplify_call_expr) <BUILT_IN_ALLOCA[_WITH_ALIGN]>: New case. Set either save_stack or keep_stack depending on CALL_ALLOCA_FOR_VAR_P. * doc/extend.texi (Variable Length): Document new behavior. * doc/generic.texi (Blocks): Document new handling of VLAs.

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.
