I used FileCheck for testing similar output with --debug-vars and was never very happy with that, because the disassembly contains tabs, so the output ends up getting misaligned in the text editor. I did it this way so that column 0 of the expected output is at column 0 of the test file, so the test looks exactly like the output.

Thanks for pointing out split-file, I didn't know about that. That looks like the best solution to this, so I'll switch the tests over to using it.
