GCC maintainers:
The _MM_SHUFFLE and _MM_SHUFFLE2 macros are currently defined in the
i386 branch. This patch adds the two macro definitions to the rs6000
config directory as requested.
The patch has been tested on
powerpc64le-unknown-linux-gnu (Power 8 LE)
With no regressions.
The request includes backporting the macro definitions to GCC 7 and GCC
8. The backport to GCC7 will require creating
the config/rs6000/emmintrin.h, config/rs6000/xmmintrin.h and
config/rs6000/x86intrin.h files with the standard header comments.
Please let me know if the patch is acceptable for mainline and for
backporting to GCC 7 and 8. Thanks
Carl Love
