Subject: __BIGGEST_ALIGNMENT__ has always been 16 on all power platforms rather
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6a69439a01178e409bc638398d97d8c0f861dc3a;p=clang

__BIGGEST_ALIGNMENT__ has always been 16 on all power platforms rather
than the default of 8 in clang, fix and update tests accordingly.
