This is what is in GCC9: $ find /opt/at13.0/ -name '*intrin.h' /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/bmi2intrin.h /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/mmintrin.h /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/x86intrin.h /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/htmintrin.h /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/pmmintrin.h /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/htmxlintrin.h /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/xmmintrin.h /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/tmmintrin.h /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/emmintrin.h /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/bmiintrin.h /opt/at13.0/lib/gcc/powerpc64le-linux-gnu/9.2.1/include/smmintrin.h So most of SSE, but not AVX yet. If course this is compromise. May not be as optimal of a native PowerISA implementation on POWER (CISC vs RISC out-of-order, super-scalar ). This is what PVECLIB is for. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
