+; RUN: llc < %s -debug-pass=Structure -start-before=loop-reduce -o /dev/null 2>&1 | FileCheck %s -check-prefix=START-BEFORE
+
+; STOP-AFTER: -loop-reduce
----------------
Could add another line like
`; RUN: not llc <  %s -debug-pass=Structure -start-before=nonexistent -o /dev/null 2>&1 | FileCheck %s -check-prefix=NONEXISTENT-PASS`
...
`; NONEXISTENT-PASS: start-before pass is not registered`
