Move some comparison simplifications to match.pd
2015-08-31 Marc Glisse <marc.glisse@inria.fr>
gcc/
* tree.h (zerop): New function.
* tree.c (zerop): Likewise.
(element_precision): Handle expressions.
* match.pd (define_predicates): Add zerop.
(x <= +Inf): Fix comment.
(abs (x) == 0, A & C == C, A & C != 0): Converted from ...
* fold-const.c (fold_binary_loc): ... here. Remove.
gcc/testsuite/
* gcc.dg/tree-ssa/cmp-1.c: New file.
