generic-match-head.c: Include cgraph.h.
2015-07-23 Richard Biener <rguenther@suse.de>
* generic-match-head.c: Include cgraph.h.
* gimple-match-head.c: Likewise.
* tree-ssa-sccvn.c (free_scc_vn): Guard against newly created
SSA names.
* fold-const.c (fold_binary_loc): Move &A ==/!= &B simplification...
* match.pd: ...to a pattern here. Add &A ==/!= 0 simplification
pattern.
