Hi, Patch resubmitted from https://gcc.gnu.org/ml/gcc-patches/2014-09/msg01400.html
The patch fix PR62128 and "gcc.target/i386/pr52252-atom.c" in
core-avx2 make check.
The test in pr62128 is exactly TEST 22 from
gcc.dg/torture/vshuf-v32qi.c. It will check if the pattern is correct
or not.
The patch developed similar to define_insn_and_split
"*avx_vperm_broadcast_<mode>".
The patch passed x86 bootstrap and make check (+2 new passes for
-march=core-avx2).
Is it ok?
Evgeny
