Subject: [NFC][PowerPC] Fast-isel VSX support test
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c5e7309ce7d64d5c09b764a0955b2213f8cf9bca;p=llvm

[NFC][PowerPC] Fast-isel VSX support test

We have fixed most of the VSX limitation in Fast-isel,
so we can remove the -mattr=-vsx for most testcases now.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@372345 91177308-0d34-0410-b5e6-96231b3b80d8
