The following incremental patch uses that in the x86 intrinsic headers. 2023-01-16 Jakub Jelinek <ja...@redhat.com> PR c++/105593 gcc/ * config/i386/xmmintrin.h (_mm_undefined_ps): Temporarily disable -Winit-self using pragma GCC diagnostic ignored. * config/i386/emmintrin.h (_mm_undefined_pd, _mm_undefined_si128): Likewise. * config/i386/avxintrin.h (_mm256_undefined_pd, _mm256_undefined_ps, _mm256_undefined_si256): Likewise. * config/i386/avx512fintrin.h (_mm512_undefined_pd, _mm512_undefined_ps, _mm512_undefined_epi32): Likewise. * config/i386/avx512fp16intrin.h (_mm_undefined_ph, _mm256_undefined_ph, _mm512_undefined_ph): Likewise. gcc/testsuite/ * g++.target/i386/pr105593.C: New test.
