Bug ID: 61560
Summary: FAIL: gcc.dg/tree-ssa/ssa-fre-32.c on arm
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org

fre pass diff between bad and good dumps
On arm-none-eabi I see a regression in the aforementioned test:
FAIL: gcc.dg/tree-ssa/ssa-fre-32.c scan-tree-dump-times fre1 "return
x_\\d+\\(D\\);" 2
Curiously this doesn't happen for an aarch64-none-elf target built from the
same revision (r211782)
I'm attaching the diff between the failing (bad) fre dump for arm and the
passing (good) dump from aarch64
