Reduce MIR dump file count for MIR-opt tests by mj10021 · Pull Request #110773 · rust-lang/rust

mj10021 · 2023-04-24T16:03:53Z

As referenced in issue #109502 , mir-opt tests previously used the -Zdump-mir=all flag, which generates very large output. This PR only dumps the passes under test, greatly reducing dump output.

just a bunch of impl nits.

Please also add some comments explaining the new field and argument

What does this magic number 3 mean? (Add the answer as a comment to the code)

Haha got it, adding

You could also use rsplit and the nth(3) operation on the iterator

Is the comment I added good or is there more info that is missing?

Ugh sorry, github didn't send my comment because I used a review

O no worries, thanks for the update 🙂

You should be able to use split_once here to avoid collecting or iterating

Examples of T-libs-api changes:

Stabilizing library features
Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
Changing public documentation in ways that create new stability guarantees
Changing observable runtime behavior of library APIs

- let proc_res = self.compile_test(should_run, self.should_emit_metadata(pm));
+ let proc_res = self.compile_test(should_run, self.should_emit_metadata(pm), Vec::new());


Why changing compile_test function at all, if in all places except one, last parameter will be Vec::new()? You can just add something like compile_test_with_passes and use it exactly in that one place.

good point, I'll make a follow up with that change

+ ╾─alloc19─╼ 03 00 00 00 │ ╾──╼....


Why this affects alloc numbers at all?

…oli-obk Issue 109502 follow up, remove unnecessary Vec::new() from compile_test() As mentioned in comment on PR rust-lang#110773 , adding a separate function to pass the test passes into the `dump-mir` is a bit nicer
