These scans from gcc.dg/vect/vect-50.c, and others similar to them in
other vect tests, hurt my brain:
/* { dg-final { scan-tree-dump-times "Vectorizing an unaligned access" 2 "vect"
{ xfail { vect_no_align } } } } */
/* { dg-final { scan-tree-dump-times "Vectorizing an unaligned access" 2 "vect"
{ target vect_hw_misalign } } } */
Both of these PASS for i686-pc-linux-gnu, causing duplicate lines in the
gcc test summary. I'm pretty sure the following accomplishes the same
goal:
/* { dg-final { scan-tree-dump-times "Vectorizing an unaligned access" 2 "vect"
{ xfail { vect_no_align && { ! vect_hw_misalign } } } } } */
That is, run the check everywhere and expect it to fail for effective
targets for which vect_no_align is true and vect_hw_misalign is false.
Tested on i686-pc-linux-gnu and arm-none-eabi. I'm enough confused that
I'm not going to call this one obvious, it needs a sanity check from
someone else; OK for trunk?
