Some optimisations in DAGCombiner cause miscompilations for targets that use TargetLowering::UndefinedBooleanContent, because they assume that the results of a SELECT_CC node are boolean values, and can be safely ANDed, ORed and XORed. These optimisations are only valid for targets that use ZeroOrOneBooleanContent or ZeroOrNegativeOneBooleanContent. This is a follow-up to D6210/r221693. llvm-svn: 222123 |
