<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang @llvm/pr-subscribers-backend-x86 Author: hpkfft.com (hpkfft) <details> <summary>Changes</summary> Intrinsics such as `_mm512_add_round_ps` take a rounding mode argument to specify the floating point rounding mode. This, and similar instructions, do NOT round their result to an integer. Thus it is inappropriate for user code to specify the existing `_MM_FROUND_TO_NEAREST_INT` when desiring to round to the nearest floating point number. This commit adds a suitable macro definition. --- Full diff: https://github.com/llvm/llvm-project/pull/99691.diff 1 Files Affected: - (modified) clang/lib/Headers/avx512fintrin.h (+1) ``````````diff diff --git a/clang/lib/Headers/avx512fintrin.h b/clang/lib/Headers/avx512fintrin.h index 4f172c74b31cb..2d7b5c534e554 100644 --- a/clang/lib/Headers/avx512fintrin.h +++ b/clang/lib/Headers/avx512fintrin.h @@ -43,6 +43,7 @@ typedef unsigned short __mmask16; /* Rounding mode macros. */ #define _MM_FROUND_TO_NEAREST_INT 0x00 +#define _MM_FROUND_TIES_TO_EVEN 0x00 #define _MM_FROUND_TO_NEG_INF 0x01 #define _MM_FROUND_TO_POS_INF 0x02 #define _MM_FROUND_TO_ZERO 0x03 `````````` </details> https://github.com/llvm/llvm-project/pull/99691 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
