This is the rs6000 version of the earlier committed x86, aarch64 and arm fixes, as create_tmp_var_raw is used because the C FE can call this outside of function context, we need to make sure the first references to those VAR_DECLs are through a TARGET_EXPR, so that it gets gimple_add_tmp_var marked in whatever function it gets expanded in. Without that DECL_CONTEXT is NULL and the vars aren't added as local decls of the containing function. 2020-04-29 Jakub Jelinek <jakub@redhat.com> PR target/94826 * config/rs6000/rs6000.c (rs6000_atomic_assign_expand_fenv): Use TARGET_EXPR instead of MODIFY_EXPR for first assignment to fenv_var, fenv_clear and old_fenv variables. For fenv_addr take address of TARGET_EXPR of fenv_var with void_node initializer. Formatting fixes.
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.
