================
Comment at: llvm/test/Transforms/InstCombine/str-int-2.ll:43
 
-define i64 @strtol_endptr_not_null() #0 {
+; Fold a call to strtol with an enptr known to be nonnull (the result
+; of pointer decrement).
----------------
enptr -> endptr


================
Comment at: llvm/test/Transforms/InstCombine/str-int-2.ll:52
+;
+  %endm1 = getelementptr inbounds i8*, i8** %pend, i32 -1
+  %call = call i64 @strtol(i8* getelementptr inbounds ([3 x i8], [3 x i8]* @.str, i32 0, i32 0), i8** %endm1, i32 10)
----------------
`i8** nonnull %pend` would be more obvious?
