Krishna Kariya 05b090ffb1 [InstCombine] Fold IntToPtr/PtrToInt to bitcast ... The inttoptr/ptrtoint roundtrip optimization is not always correct. We are working towards removing this optimization and adding support to specific cases where this optimization works. This patch is the first one on this line. Consider the example: %i = ptrtoint i8* %X to i64 %p = inttoptr i64 %i to i16* %cmp = icmp eq i8* %load, %p In this specific case, the inttoptr/ptrtoint optimization is correct as it only compares the pointer values. In this patch, we fold inttoptr/ptrtoint to a bitcast (if src and dest types are different). Differential Revision: https://reviews.llvm.org/D105088		2021-07-18 23:13:25 +02:00
