[Zixuan Wu via Phabricator via cfe-commits]

zixuan-wu added inline comments.


================
Comment at: llvm/test/CodeGen/CSKY/intrinsic.ll:21
+entry:
+  %ntz = call i32 @llvm.cttz.i32(i32 %x, i1 1)
+  ret i32 %ntz
----------------
I think we can also test the condition that the second argument is zero.
