True. That said, the pex interface is a bit cumbersome to use, and it's probably not worth it to fork and exec cmp when we can easily do the work ourselves. I didn't realize we already realied on all of the mmap features needed for this, thanks for pointing it out.

Here's a patch that merges the 3 other patches that built upon or fixed
the initial -fcompare-debug into the one posted upthread, and that
addresses all of your comments, except for the -fdump-final-insns
bootstrap compare.

Ok?

Ok.
