            Bug ID: 82442
           Summary: vect/pr31699.c fails on arm
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: clyon at gcc dot gnu.org
  Target Milestone: ---

Since r253403, the gcc.dg/vect/pr31699.c is now enabled on arm*hf targets
thanks to vect_float effective target. It used to be unsupported with
vect_double.

Now that it is enabled, it fails on such targets:
FAIL:    gcc.dg/vect/pr31699.c -flto -ffat-lto-objects  scan-tree-dump-times
vect "vectorized 1 loops" 2
FAIL:    gcc.dg/vect/pr31699.c scan-tree-dump-times vect "vectorized 1 loops" 2

for instance,
--target arm-none-linux-gnueabihf
--with-mode arm
--with-cpu cortex-a9
--with-fpu neon-fp16
