+; CHECK-NEXT:    [[P:%.*]] = inttoptr i64 [[I]] to i8*
+; CHECK-NEXT:    [[CMP:%.*]] = icmp eq i8* [[P]], [[Y:%.*]]
+; CHECK-NEXT:    ret i1 [[CMP]]
----------------
As you can see, this test ends up being the same as the previous due to complexity canonicalization. You should replace `%Y` with an instruction rater than an argument to actually test the commuted variant. (grep "thwart complexity" and getComplexity for context).

Comment at: llvm/test/Transforms/InstCombine/ptr-int-ptr-icmp.ll:50

+define i1 @func4(i16* %X, i8* %Y) {
+; CHECK-LABEL: @func4(
----------------
It would be nice to pick more meaningful names for the tests, e.g. this could be `integer_type_too_small`.
