URL: https://github.com/llvm/llvm-project/commit/d54ff4c9b91250b93cf6b05377246fbad9e028ce DIFF: https://github.com/llvm/llvm-project/commit/d54ff4c9b91250b93cf6b05377246fbad9e028ce.diff LOG: Add _MM_FROUND_TO_NEAREST_TIES_EVEN to avx512fintrin.h (#99691) 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.
