Subject: [testsuite] Fix PR94079 by respecting vect_hw_misalign [PR94079]
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e7c4084d11b957d925ba586f86db2f346fb3bfe0;p=gcc.git

[testsuite] Fix PR94079 by respecting vect_hw_misalign [PR94079]

This is another vect case which requires special handling with
vect_hw_misalign.  The alignment of the second part requires
misaligned vector access supports.  This patch is to adjust
the related guard condition and comments.

Verified it on ppc64-redhat-linux (Power7 BE).
