The "classic" PowerPCs (6xx/7xx) are not STRICT_ALIGNMENT, but their floating point units are. This is not normally a problem, the ABIs make everything FP aligned. The RTL patterns converting FP to integer however get a potentially unaligned destination, and we do not want to do an stfiwx on that on such older CPUs. This fixes it. It does not change anything for TARGET_MFCRF targets (POWER4 and later). It also won't change anything for strict-alignment targets, or CPUs without hardware FP of course, or CPUs that do not implement stfiwx (older 4xx/5xx/8xx). It does not change the corresponding fixuns* pattern, because that can not be enabled on any CPU that cannot handle unaligned FP well. PR target/89746 * config/rs6000/rs6000.md (fix_trunc<mode>si2_stfiwx): If we have a non-TARGET_MFCRF target, and the dest is memory but not 32-bit aligned, go via a stack temporary.

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.
