[PATCH] D28817: Add SparseBitVector::find_last()

[Daniel Berlin via Phabricator via llvm-commits]

dberlin added inline comments.


================
Comment at: llvm/include/llvm/ADT/SparseBitVector.h:141
+        return Idx * BITWORD_SIZE + BITWORD_SIZE -
+               countLeadingZeros(Bits[Idx]) - 1;
+    }
----------------
Don't you really just want counttrailingzeros, and the index is bitword_size - count trailing zeros?
