            Bug ID: 96376
           Summary: [11 regression] vect/vect-alias-check.c and
                    vect/vect-live-5.c fail on armeb
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: clyon at gcc dot gnu.org
  Target Milestone: ---

I've noticed regressions on target armeb-none-linux-gnueabihf --with-mode arm
--with-cpu cortex-a9 --with-fpu neon-fp16:
gcc.dg/vect/vect-alias-check.c -flto -ffat-lto-objects  scan-tree-dump-times
vect "vectorized 1 loops" 1
gcc.dg/vect/vect-alias-check.c scan-tree-dump-times vect "vectorized 1 loops" 1
gcc.dg/vect/vect-live-5.c -flto -ffat-lto-objects  scan-tree-dump-times vect
"vectorized 1 loops" 1
gcc.dg/vect/vect-live-5.c scan-tree-dump-times vect "vectorized 1 loops" 1

In my logs I can see:
PASS: gcc.dg/vect/vect-live-5.c execution test
gcc.dg/vect/vect-live-5.c: pattern found 0 times
FAIL: gcc.dg/vect/vect-live-5.c scan-tree-dump-times vect "vectorized 1 loops"
1

PASS: gcc.dg/vect/vect-alias-check.c (test for excess errors)
gcc.dg/vect/vect-alias-check.c: pattern found 0 times
FAIL: gcc.dg/vect/vect-alias-check.c scan-tree-dump-times vect "vectorized 1
loops" 1
