Author: Jakub Jelinek <jakub@redhat.com>
Date:   Sat Jan 23 09:41:58 2021 +0100

    rs6000: Fix up __m64 typedef in mmintrin.h [PR97301]

    The x86 __m64 type is defined as:
    /* The Intel API is flexible enough that we must allow aliasing with other
       vector types, and their scalar components.  */
    typedef int __m64 __attribute__ ((__vector_size__ (8), __may_alias__));
    and so matches the comment above it in that reads and stores through
    pointers to __m64 can alias anything.
    But in the rs6000 headers that is the case only for __m128, but not __m64.

    The following patch adds that attribute, which fixes the
    FAIL: gcc.target/powerpc/sse-movhps-1.c execution test
    FAIL: gcc.target/powerpc/sse-movlps-1.c execution test
    regressions that appeared when Honza improved ipa-modref.
