--- Comment #4 from Roger Sayle <roger at nextmovesoftware dot com> ---
I think the mention of slp2 and pr104240.c in the bug report is bogus, and =
is a
glitch in the automated regression checking scripts.  The real problem is t=
hat
my new test case for pr102950.c is failing on powerpc64.  After a great dea=
l of
head scratching on why EVRP is producing different results on this platform,
I've just realized that "char" must be unsigned on this target.  Replacing
"char" with "signed char" in gcc.dg/pr102950.c fixes the problem.  I'll com=
mit
this fix as obvious.  But I want to avoid anyone wasting time (like I did)
trying to figure out why my patch should be the cause of an -flto failure of
bb-slp-pr104240.c [which might be failure, but unrelated to the pr102950.c
issue/bisect].=
