--- Comment #12 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by H.J. Lu <h...@gcc.gnu.org>: https://gcc.gnu.org/g:72264a639729a5dcc21dbee304717ce22b338bfd commit r12-2765-g72264a639729a5dcc21dbee304717ce22b338bfd Author: H.J. Lu <hjl.to...@gmail.com> Date: Sat Jul 17 07:44:45 2021 -0700 <x86gprintrin.h>: Add pragma GCC target("general-regs-only") 1. Intrinsics in <x86gprintrin.h> only require GPR ISAs. Add #if defined __MMX__ || defined __SSE__ #pragma GCC push_options #pragma GCC target("general-regs-only") #define __DISABLE_GENERAL_REGS_ONLY__ #endif and #ifdef __DISABLE_GENERAL_REGS_ONLY__ #undef __DISABLE_GENERAL_REGS_ONLY__ #pragma GCC pop_options #endif /* __DISABLE_GENERAL_REGS_ONLY__ */ to <x86gprintrin.h> to disable non-GPR ISAs so that they can be used in functions with __attribute__ ((target("general-regs-only"))). 2. When checking always_inline attribute, if callee only uses GPRs, ignore MASK_80387 since enable MASK_80387 in caller has no impact on callee inline. gcc/ PR target/99744 * config/i386/i386.c (ix86_can_inline_p): Ignore MASK_80387 if callee only uses GPRs. * config/i386/ia32intrin.h: Revert commit 5463cee2770. * config/i386/serializeintrin.h: Revert commit 71958f740f1. * config/i386/x86gprintrin.h: Add #pragma GCC target("general-regs-only") and #pragma GCC pop_options to disable non-GPR ISAs. gcc/testsuite/ PR target/99744 * gcc.target/i386/pr99744-3.c: New test. * gcc.target/i386/pr99744-4.c: Likewise. * gcc.target/i386/pr99744-5.c: Likewise. * gcc.target/i386/pr99744-6.c: Likewise. * gcc.target/i386/pr99744-7.c: Likewise. * gcc.target/i386/pr99744-8.c: Likewise.
