https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71956 --- Comment #5 from Yuri Rumyantsev --- This bug is fixed by Author: ppalka Date: Sat Aug 27 22:00:17 2016 New Revision: 239798 URL: https://gcc.gnu.org/viewcvs?rev=239798=gcc=rev Log: Fix folding of VECTOR_CST comparisons gcc/ChangeLog: PR tree-optimization/71077 PR tree-optimization/68542 * fold-const.c (fold_relational_const): Fix folding of VECTOR_CST comparisons that have a scalar boolean result type. (selftest::test_vector_folding): New static function. (selftest::fold_const_c_tests): Call it. gcc/testsuite/ChangeLog: PR tree-optimization/71077 * gcc.target/i386/pr71077.c: New test. Added: trunk/gcc/testsuite/gcc.target/i386/pr71077.c Modified: trunk/gcc/ChangeLog trunk/gcc/fold-const.c trunk/gcc/testsuite/ChangeLog So this bug must be closed.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71956 --- Comment #3 from Yuri Rumyantsev --- It turned out that after r235653 (with minor int->bool type change) 176.gcc started RF. If we turn off vrp phase benchmark passes. The problem fail is sched.c. Note that avx2 is essential for reproducing. Try to understand what the issue is.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71956 Yuri Rumyantsev changed: What|Removed |Added CC||ysrumyan at gmail dot com --- Comment #2 from Yuri Rumyantsev --- Jakub, I removed both your revisions in cse.c (c1) but it did not help - 176.gcc stll gets RF on avx2 but not on avx. I assume that masked stores are responsible for it since we have them in binaries: .L2437: vmovd %ecx, %xmm1 vpxor %xmm5, %xmm5, %xmm5 addl-40(%ebp), %eax movl-28(%ebp), %edx vpbroadcastd-36(%ebp), %ymm4 vpaddd .LC1, %ymm4, %ymm2 vpbroadcastd%xmm1, %ymm1 leal(%edx,%eax,4), %eax vpsrlvd %ymm2, %ymm1, %ymm2 vpaddd %ymm7, %ymm4, %ymm3 vpand %ymm6, %ymm2, %ymm2 vpcmpeqd%ymm5, %ymm2, %ymm2 vpcmpeqd%ymm5, %ymm2, %ymm2 vptest %ymm2, %ymm2 je .L2446 vpmaskmovd %ymm0, %ymm2, (%eax) .L2446: vpsrlvd %ymm3, %ymm1, %ymm2 vpxor %xmm3, %xmm3, %xmm3 leal32(%eax), %edx vpaddd .LC3, %ymm4, %ymm4 vpand %ymm6, %ymm2, %ymm2 vpcmpeqd%ymm3, %ymm2, %ymm2 vpcmpeqd%ymm3, %ymm2, %ymm2 vptest %ymm2, %ymm2 je .L2447 vpmaskmovd %ymm0, %ymm2, (%edx) Will try to determine the correct revision responsible for it.
