Re: [tree-ssa] Fix bootstrap failure caused by tree-ssa-loop.c




You can see this lossage in action if you have the loop code enabled and
do a checking bootstrap with -O1.

??? It passed without any problems for me. Interesting, I will have to
check whether I don't bootstrap with checking disabled, but I would be
very surprised if it was the case.
Hmm, I may have mis-spoken. Try with -O2 -fno-tree-pre, checking enabled.

Let me guess, PRE's rebuilding of the dominator tree masks this?
