Currently we miss folds with undef and identity values for binary ops that do not fold to undef in general. We can generalize the identity simplifications and do them before checking for undef in particular. Alive checks: * OR - https://rise4fun.com/Alive/8OsK * AND - https://rise4fun.com/Alive/e3tE This will also allow us to remove some now redundant cases throughout the function, but I would like to do this as follow-up. That should make tracking down potential issues easier. Reviewers: spatel, RKSimon, lebedev.ri Reviewed By: spatel Differential Revision: https://reviews.llvm.org/D70169 |
