--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Matthias Kretz <mkr...@gcc.gnu.org>: https://gcc.gnu.org/g:63b73f14be97a9fe8621ec1a523b6dd19bde72dc commit r13-8705-g63b73f14be97a9fe8621ec1a523b6dd19bde72dc Author: Matthias Kretz <m.kr...@gsi.de> Date: Fri Jun 2 13:44:22 2023 +0200 libstdc++: Replace use of incorrect non-temporal store The call to the base implementation sometimes didn't find a matching signature because the _Abi parameter of _SimdImpl* was "wrong" after conversion. It has to call into <new ABI tag>::_SimdImpl instead of the current ABI tag's _SimdImpl. This also reduces the number of possible template instantiations. Signed-off-by: Matthias Kretz <m.kr...@gsi.de> libstdc++-v3/ChangeLog: PR libstdc++/110054 * include/experimental/bits/simd_builtin.h (_S_masked_store): Call into deduced ABI's SimdImpl after conversion. * include/experimental/bits/simd_x86.h (_S_masked_store_nocvt): Don't use _mm_maskmoveu_si128. Use the generic fall-back implementation. Also fix masked stores without SSE2, which were not doing anything before. (cherry picked from commit 27e45b7597d6fb1a71927d658a0294797b720c0a)
