Committed, thanks.

Hmmm, it looks like this was introduced to mainline only by this patch:
http://gcc.gnu.org/ml/gcc-patches/2004-02/msg00441.html

which removes the PROP_REG_INFO argument from the final update_live_info
call in regrename_optimize ...

Honza, what was the reason for removing PROP_REG_INFO?  Should it be
added back, or is my simple fix an OK solution?

Bye,
Ulrich
