From 9151ecbb5e5a3d2ee30826ab9cce3aa5575e3a70 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Mon, 16 Dec 2024 05:11:26 +0800 Subject: [PATCH] x86-64: Disable libmvec ABI test for Clang Unlike GCC, libmvec support in Clang is hard-coded. Clang doesn't use macros defined in to support new libmvec functions added to glibc and can't vectorize all test loops to test libmvec ABI: https://github.com/llvm/llvm-project/issues/120868 disable libmvec ABI test for Clang.
