Move "X +- C1 CMP C2 to X CMP C2 -+ C1" to match.pd
2016-05-02 Marc Glisse <marc.glisse@inria.fr>
gcc/
* flag-types.h (enum warn_strict_overflow_code): Move ...
* coretypes.h: ... here.
* fold-const.h (fold_overflow_warning): Declare.
* fold-const.c (fold_overflow_warning): Make non-static.
(fold_comparison): Move the transformation of X +- C1 CMP C2
into X CMP C2 -+ C1 ...
* match.pd: ... here.
* gimple-fold.c (fold_stmt_1): Protect with
fold_defer_overflow_warnings.
gcc/testsuite/
* gcc.dg/tree-ssa/20040305-1.c: Adjust.
