gcc/ChangeLog: PR target/97642 * config/i386/i386-expand.c (ix86_expand_special_args_builtin): Don't move all-ones mask operands into register. * config/i386/sse.md (UNSPEC_MASKLOAD): New unspec. (*<avx512>_load<mode>_mask): New define_insns for masked load instructions. (<avx512>_load<mode>_mask): Changed to define_expands which specifically handle memory or all-ones mask operands. (<avx512>_blendm<mode>): Changed to define_insns which are same as original <avx512>_load<mode>_mask with adjustment of operands order. (*<avx512>_load<mode>): New define_insn_and_split which is used to optimize for masked load with all one mask. gcc/testsuite/ChangeLog: * gcc.target/i386/avx512bw-vmovdqu16-1.c: Adjust testcase to make sure only masked load instruction is generated. * gcc.target/i386/avx512bw-vmovdqu8-1.c: Ditto. * gcc.target/i386/avx512f-vmovapd-1.c: Ditto. * gcc.target/i386/avx512f-vmovaps-1.c: Ditto. * gcc.target/i386/avx512f-vmovdqa32-1.c: Ditto. * gcc.target/i386/avx512f-vmovdqa64-1.c: Ditto. * gcc.target/i386/avx512vl-vmovapd-1.c: Ditto. * gcc.target/i386/avx512vl-vmovaps-1.c: Ditto. * gcc.target/i386/avx512vl-vmovdqa32-1.c: Ditto. * gcc.target/i386/avx512vl-vmovdqa64-1.c: Ditto. * gcc.target/i386/pr97642-1.c: New test. * gcc.target/i386/pr97642-2.c: New test.
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.
