Bug ID: 103998
Summary: [12 Regression] Recent vectorizer testsuite
regressions on x86
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
I'm seeing on x86_64-linux:
make check-gcc RUNTESTFLAGS="--target_board=unix\{-m32,-m64\}
vect.exp=vect-tail-nomask-1.c i386.exp='pr88531* vect-reduc-1.c'"
rm -rf testsuite/gcc-parallel

make[1]: Leaving directory '/usr/src/gcc/obj/gcc'
None of this was present when I bootstrapped/regtested 24 hours ago with
r12-6420 reverted.
If I revert r12-6523 and r12-6420 on current trunk, then all these pass again.
