Hi all,In this second patch I add the transformation mentioned in the subject to simplify-rtx.c. In combination with the first patch to combine, combine_simplify_rtx now picks it up in the testcase and does the right thing by not emitting an extra negate after the conditional negate operation. Bootstrapped and tested on aarch64, arm, x86_64. Ok for trunk? Thanks, Kyrill 2015-07-16 Kyrylo Tkachov <kyrylo.tkac...@arm.com> * simplify-rtx.c (simplify_unary_operation_1, NEG case): (neg (x ? (neg y) : y)) -> !x ? (neg y) : y.
OK. jeff
