Is GDB smart enough to deal w/no condition_regs? On some Book-E

I think that those three are enough to express breakpoint ranges.
Basically a breakpoint range is a breakpoint that can have a high

This is a resubmission of the patches I first sent on December 9th.
Sorry for the delay. I have addressed most of the comments, and I'll
follow up on the others.

What do we do in EDM mode? We need a flag somewhere to determine if

calls fails?
I really don't have a good answer to this. I'm open to any and all
advice.

This is a good write up. We should have it as a commit message for
the first patch.
No, that should go into Documentation/powerpc/
