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
