Hi!
- Fix AVX vector permutation handling (PR target/43107)
http://gcc.gnu.org/ml/gcc-patches/2010-02/msg00736.html
2010-02-18 Jakub Jelinek<jakub@redhat.com>
PR target/43107
* config/i386/i386.c (avx_vpermilp_parallel): Reject indexes
greater or equal to nelt instead of 2 * nelt.
(expand_vec_perm_1): When op0 and op1 are equal, mask indexes
with nelt - 1.
Please CSE (nelt -1) into a temporary.
OK with that change.
Thanks,
Uros.
