A : -A` set of patterns to use bitwise_equal_p. This improves the `A CMP 0 ? A : -A` set of match patterns to use bitwise_equal_p which allows an nop cast between signed and unsigned. This allows catching a few extra cases which were not being caught before. OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions. gcc/ChangeLog: PR tree-optimization/101541 * match.pd (A CMP 0 ? A : -A): Improve using bitwise_equal_p. gcc/testsuite/ChangeLog: PR tree-optimization/101541 * gcc.dg/tree-ssa/phi-opt-36.c: New test. * gcc.dg/tree-ssa/phi-opt-37.c: New test.
