I tested Dave's patch from comment #32 and it is fixing the hppa64-* bootstrap
failure. Dave are you going to submit that patch for approval or are you
looking for someone else to pick this up?

No problem. If the compiler is not being miscompiled, I will be able to
look at it

DF_REF_INSN (def) is 0. It looks like the ICE can be avoided by
a check on def_insn.
--- Comment #21 from bonzini at gnu dot org 2006-11-30 18:48 ---
Dave, is the compiler being miscompiled here? Can you reproduce the failure
with ../configure --disable-bootstrap make? If so, what is the backtrace?
Thanks,
Paolo

Just adding DF_HARD_REGS is not enough. At least this bit:

This may be a df bug too. I don't know if it is ok to expect, when
DF_HARD_REGS is set, that the list of defs include a def for every hard
register that is call-clobbered and live at the call?

The only three instructions fwprop touches are done into:
Before:
(insn 112 2 7 2 foo.c:13 (set (reg/f:DI 72)

fwprop says it is r29 invalided by a call:
invalidated by call 0, 1, 2, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29,

Magic with hard regs
Paolo Bonzini proably can think of a real fix, but it'll have to look something
like this:
