[Bug preprocessor/87299] #pragma GCC target behaves differently when using -save-temps
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87299 --- Comment #8 from Gwenole Beauchesne --- Hi, can you please consider a backport to GCC 13 branch? The patch applies cleanly as is, but causes regressions that are further fixed with e45c564e (for PR pch/112319). GCC 13 is the first and most complete compiler for modern C++ (>= C++20) support and readily available, or soon available, as the system compiler for major distributions. This is useful to C++ projects that (debately) use multiple wrappers for SIMD support (xsimd, simde, mipp, etc.), but without correct support for runtime dispatching. So, using #pragma GCC target is a handy solution for that. Thanks.
