(scev_const_prop): If folded_casts and type has undefined overflow, use force_gimple_operand instead of force_gimple_operand_gsi and for each added stmt if it is assign with arith_code_with_undefined_signed_overflow, call rewrite_to_defined_overflow. * tree-ssa-loop-im.c: Don't include gimplify-me.h, include gimple-fold.h instead. (arith_code_with_undefined_signed_overflow, rewrite_to_defined_overflow): Moved to ... * gimple-fold.c (arith_code_with_undefined_signed_overflow, rewrite_to_defined_overflow): ... here. No longer static. Include gimplify-me.h. * gimple-fold.h (arith_code_with_undefined_signed_overflow, rewrite_to_defined_overflow): New prototypes. * gcc.c-torture/execute/pr59387.c: New test.
