New Revision: 158639
URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=158639
Log:
* 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.
