This adds a generic-match.h header to cover these (even though they are not public API).
Richard. 2014-10-22 Richard Biener <rguent...@suse.de> * generic-match.h: New file. * generic-match-head.c: Include generic-match.h, not gimple-match.h. * fold-const.c: Include generic-match.h. (fold_unary_loc): Remove local prototype of generic_simplify. (fold_binary_loc): Likewise. (fold_ternary_loc): Likewise.
