From: "cvs-commit at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/109504] [12/13/14 Regression] Compilation fails with pragma GCC target sse4.1 and immintrin.h Date: Wed, 19 Jul 2023 01:36:11 +0000 [thread overview] Message-ID: <bug-109504-4-qivtgLMnBX@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-109504-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109504 --- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by hongtao Liu <liuhongt@gcc.gnu.org>: https://gcc.gnu.org/g:9a19fa8b616f83474c35cc5b34a3865073ced829 commit r14-2628-g9a19fa8b616f83474c35cc5b34a3865073ced829 Author: liuhongt <hongtao.liu@intel.com> Date: Tue Apr 18 14:53:04 2023 +0800 Support type _Float16/__bf16 independent of SSE2. Enable _Float16 and __bf16 all the time but issue errors when the types are used in conversion, unary operation, binary operation, parameter passing or value return when TARGET_SSE2 is not available. Also undef macros which are used by libgcc/libstdc++ to check the backend support of the _Float16/__bf16 types when TARGET_SSE2 is not available. gcc/ChangeLog: PR target/109504 * config/i386/i386-builtins.cc (ix86_register_float16_builtin_type): Remove TARGET_SSE2. (ix86_register_bf16_builtin_type): Ditto. * config/i386/i386-c.cc (ix86_target_macros): When TARGET_SSE2 isn't available, undef the macros which are used to check the backend support of the _Float16/__bf16 types when building libstdc++ and libgcc. * config/i386/i386.cc (construct_container): Issue errors for HFmode/BFmode when TARGET_SSE2 is not available. (function_value_32): Ditto. (ix86_scalar_mode_supported_p): Remove TARGET_SSE2 for HFmode/BFmode. (ix86_libgcc_floating_mode_supported_p): Ditto. (ix86_emit_support_tinfos): Adjust codes. (ix86_invalid_conversion): Return diagnostic message string when there's conversion from/to BF/HFmode w/o TARGET_SSE2. (ix86_invalid_unary_op): New function. (ix86_invalid_binary_op): Ditto. (TARGET_INVALID_UNARY_OP): Define. (TARGET_INVALID_BINARY_OP): Define. * config/i386/immintrin.h [__SSE2__]: Remove for fp16/bf16 related instrinsics header files. * config/i386/i386.h (VALID_SSE2_TYPE_MODE): New macro. gcc/testsuite/ChangeLog: * gcc.target/i386/pr109504.c: New test. * gcc.target/i386/sse2-bfloat16-1.c: Adjust error info. * gcc.target/i386/sse2-float16-1.c: Ditto. * gcc.target/i386/sse2-float16-4.c: New test. * gcc.target/i386/sse2-float16-5.c: New test. * g++.target/i386/float16-1.C: Adjust error info. libgcc/ChangeLog: * config/i386/t-softfp: Add -msse2 to libbid HFtype related files.
