This PR is likely due to revision 158639:
Author: bernds
Date: Thu Apr 22 10:42:21 2010 UTC (3 days, 22 hours ago)
Changed paths: 4
Log Message:
* ifcvt.c (dead_or_predicable): Use df_simulate_find_defs and
df_simulate_find_noclobber_defs as appropriate. Keep track of an
extra set merge_set_noclobber, and use it to relax the final test
slightly.
* df.h (df_simulate_find_noclobber_defs): Declare.
* df-problems.c (df_simulate_find_defs): Don't ignore partial or
conditional defs.
(df_simulate_find_noclobber_defs): New function.
I have successfully bootstrapped revision 158633 (with r158643), revision
158639 (+r158643) fails to bootstrap with an ICE while configuring libgcc at
stage 2, and revision 158634 (+r158643) is now at stage 3. I doubt that the
revision in between 158634 and 158639 can break bootstap on ppc.
