The October 23rd, 2009 change to tree-ssa-pre.c breaks calculix on powerpc with
-ffast-math. When you start up the benchmark with reference input, it fails
almost immediately because the calculations don't converge.
At this point, I don't have a narrowed down test case, but the following
change:

This change merely turns off PRE in cold code regions. So if -fno-tree-pre
breaks calculix for you I'd guess some later optimization manages to

What options do you build ca

I have tried to simplify the code, but I have created only problem with int
(not with user structure). In real code we have also something like this:
