- Reply-to: Jakub Jelinek <jakub at redhat dot com>
Hi!
We don't have a V4SImode vec_interleave_{low,high}v4si patterns
for TARGET_SSE, the following patch works around that by using
what TARGET_SSE has (vec_interleave_{low,high}v4sf) instead of
ICEing.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

* config/i386/i386.c (expand_vec_perm_interleave2): If d->vmode is
V4SImode, !TARGET_SSE2 and punpck[lh]* is needed, change dremap.vmode
to V4SFmode.
* gcc.dg/torture/vshuf-16.inc: Add interleave low and high
permutations.
* gcc.dg/torture/vshuf-32.inc: Likewise.
* gcc.dg/torture/vshuf-4.inc: Likewise.
* gcc.dg/torture/vshuf-8.inc: Likewise.
