+; This test documents how the IR dumped for loop passes differs with -print-loop-func-scope
+; and -print-module-scope
+;   - Without -print-loop-func-scope, dumps only the loop, with 3 sections- preheader,
+;     loop, and exit blocks
+;   - With -print-loop-func-scope, dumps only the function which contains the loop
+;   - With -print-module-scope, dumps the entire module containing the loop, and disregards
+;     the -print-loop-func-scope flag.
