Re: [PATCH] testsuite/63175 - fix powerpc64 test failure

[David Edelsohn]

The patch below fixes a failure of the test on powerpc64.
The test looks for the lxv (Load VSX Vector) instruction
which is emitted on powerpc64le but on powerpc64 gcc emits
an lvx (Load Vector Indexed). Both are correct here.

Is this okay to commit to trunk?

Okay.

Thanks, David

You might want to remove the backslashes before the parens, which are
ignored anyway.
