Mike, this isn't about addresses. It's about an earlyclobber output overlapping

the output need not be marked earlyclobber -

Something like this maybe? I don't know much about the machine and can't say
whether the earlyclobber is justified, but looking at my dumps this appears to
prevent the problematic peephole from triggering.

Something like this maybe? Tries to determine if too large a fraction of blocks

what triggers the compile time issues).

A slightly hackish attempt to solve it, by not removing stores to the PIC
register. As far as I can tell we now end up with an unnecessary store to

Yeah, my current theory is that r87 is spilled at the start, then the spill reg
is inherited in all the existing uses of it, and lra thinks it can avoid
storing it to memory.
