This patch, commit r13-6945-g429a7a88438cc8, caused a
test-suite regression; FAIL for 'gcc.dg/tree-ssa/pr23109.c
scan-tree-dump-not recip "reciptmp"' for cris-elf that I
logged at PR109363.
Perhaps it's somewhat of a similar nature as Walloca-13.c
but then again it's not an bogus warning that's gone.
Is it expected and I should just blankly xfail it or is it
worth more attention? I'm a bit surprised that it hasn't
shown up for other targets though.
I already let Andrew know -- it's affecting a ton of targets. It may be
the case that we just need to adjust the param for that test.
