I am not aware of any lingering bootstrap problem, and messages to the gcc-testresults mailing list seem to confirm that. There is a successful report on Feb 27.

I did an update and bootstrap today, and it did fail. I tracked it down to a problem in global.c. The list of registers to allocate had two of them swapped. This is presumably a problem with allocno_compare, which does some FP arithmetic. I see Steve Ellcey checked in a patch which enabled inline FP divides by default. If I disable that (by changing TARGET_DEFAULT), then the bootstrap succeeds.

So the inline FP divide code is somehow causing allocno_compare in global.c to be miscompiled. I haven't had a chance to look at why yet.
