Most of that time is from <x86intrin.h> as expected. >intrin0.h took ~2ms to parse.
Did this same test with the most recent change that included the `yvals_core.h` interposing header. The parse time was around ~170ms since `intrin0.h` is still cheaper than the old `intrin.h`. This was tested with the MSVC STL shipped with MSVC 1938. https://github.com/llvm/llvm-project/pull/75711 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
