Hi,
The enclosed patch fixes the regression caused by dataflow merge.
This is a latent bug revealed by better loglinks in dataflow branch.
Bootstrapped and reg-tested on x86-64.
Hans-Peter Nilsson tested the change on cris and it fixed all regressions.
Approved by Ian Lance Taylor on IRC.
Committed as revision 125634.
ChangeLog:
2007-06-11 Seongbae Park <seongbae.park@gmail.com>
* combine.c (subst): Use reg_overlap_mentioned_p
instead of comparing register numbers directly.
