AFAICT the patch in comment #10 affects only powerpc-apple-darwin*. Could it be
committed now in order to allow the automatic tester 'regress' to start again?

That seems like you've tried to debug xgcc instead of cc1. Of course the
backtrace from cc1 is interesting, not from xgcc (which doesn't SIGBUS).
Run xgcc with additional -v option, and copypaste the cc1 command line

The last good build for powerpc-apple-darwin9 on regress was at r157263 so...
r157264
must be the offending commit. Is powerpc64-unknown-linux-gnu still
bootstrapping?

Guess rs6000_delegitimize_address needs to handle UNSPEC_MACHOPIC_OFFSET.

With the patch in comment #10 I am now at stage 2. So far so good! Thanks for
the patch.
Why is rs6000_delegitimize_address much simpler (even with the patch) than
ix86_delegitimize_address?
