<pre>For example:
$ cat /tmp/x
BAR-DAG: world
FOO-DAG: Hello
$ echo Hello world | bin/FileCheck --check-prefix=FOO --check-prefix=BAR /tmp/x
(all good)
$ echo Hello LLVM | bin/FileCheck --check-prefix=FOO --check-prefix=BAR /tmp/x
/tmp/x:1:10: error: FOO-DAG: expected string not found in input
BAR-DAG: world
^
<stdin>:1:1: note: scanning from here
Hello LLVM
^
Input file: <stdin>
Check file: /tmp/x
-dump-input=help explains the following input dump.
Input was:
<<<<<<
1: Hello LLVM
dag:1 X~~~~~~~~~ error: no match found
<span class="quote">>>>>>></span >
Note that the error says "FOO-DAG: expected string not found in input" even
though it's really BAR-DAG that's failing.</pre>
