r251537 - in /trunk/gcc: ChangeLog cprop.c df-p...


Author: rsandifo
Date: Wed Aug 30 15:28:18 2017
New Revision: 251537

URL: https://gcc.gnu.org/viewcvs?rev=251537&root=gcc&view=rev
Log:
Drop df_ from df_read_modify_subreg_p

...it's really a general RTL predicate, rather than something that depends
on the DF state.  Thanks to Segher for the suggestion.
