When -fdump-tree-ifcvt-stats is enabled, GCC emits
"Applying if-conversion" string in status file (.ifcvt).
It does not if-convert many loops, so it would be helpful
you can identify mis-compiled object file.
Meanwhile I'll try if I can reproduce it on powerpc-darwin.
I have started couple of bootstrap. Lets see. I'll be
offline couple for hours.
