https://reviews.llvm.org/D70922 This adds a hook to allow targets to define exactly what extension operation should be performed for widening constants. This handles cases like widening i1 true which would end up becoming -1 which affects code quality during combines. Additionally, in order to stay consistent with how DAG is promoting constants, we now signextend for byte sized types and zero extend otherwise (by default). Targets can of course override this if necessary. |
