...I used my small-sampled data as below, the program seems to take forever. I am not sure if it is due to slowness or there is something wrong with my codes or data manipulation. Please be advised ! The data is described as the output from str() function. The call to rpart is like: library(rpart) test_tree<-rpart(x$V142 ~ ., data=x, parms=list(split='gini'), cp =0.01) the response variable is $V142, with 3 levels. Thanks for your suggestions!

>> Are you sure there isn't any test coverage? As far as I can tell, the tests from https://reviews.llvm.org/rL133503 are still in the tree. I looked at those, but none of them include the full pattern that decomposes into bswap and rol. I debugged through the X86 bswap.ll test and verified none of those cases make it through MatchBSwapHWord (they get handled in MatchBSwapHWordLow
