Can you share pointers/resources to improve the CHECK commands for filechecks in test cases.

r? mir-opt

I don't have the knowledge to effectively review the added test conditions, though it looks reasonable enough to me.

I'm not sure I understand the question. Do you mean docs on the filecheck syntax? Or something else?

Yes, for filecheck syntax.

Yes, for filecheck syntax.

the closest we have is https://github.com/rust-lang/rust/blob/master/tests/mir-opt/README.md#filecheck-directives, which is very sparse, so if you figure out something useful, don't hesitate to add it to that file
