New attribute parsing infrastructure #135726

jdonszelmann · 2025-01-19T11:27:11Z

Another step in the plan outlined in #131229

introduces infrastructure for structured parsers for attributes, as well as converting a couple of complex attributes to have such structured parsers.

This PR may prove too large to review. I left some of my own comments to guide it a little. Some general notes:

The first commit is basically standalone. It just preps some mostly unrelated sources for the rest of the PR to work. It might not have enormous merit on its own, but not negative merit either. Could be merged alone, but also doesn't make the review a whole lot easier. (but it's only +274 -209)
The second commit is the one that introduces new infrastructure. It's the important one to review.
The 3rd commit uses the new infrastructure showing how some of the more complex attributes can be parsed using it. Theoretically can be split up, though the parsers in this commit are the ones that really test the new infrastructure and show that it all works.
The 4th commit fixes up rustdoc and clippy. In the previous 2 they didn't compile yet while the compiler does. Separated them out to separate concerns and make the rest more palatable.
The 5th commit blesses some test outputs. Sometimes that's just because a diagnostic happens slightly earlier than before, which I'd say is acceptable. Sometimes a diagnostic is now only emitted once where it would've been twice before (yay! fixed some bugs). One test I actually moved from crashes to fixed, because it simply doesn't crash anymore. That's why this PR Closes ICE: malformed malformed repr(align(N)) #132391. I think most choices I made here are generally reasonable, but let me know if you disagree anywhere.
The 6th commit adds a derive to pretty print attributes
The 7th removes smir apis for attributes, for the time being. The api will at some point be replaced by one based on rustc_ast_data_structures::AttributeKind

In general, a lot of the additions here are comments. I've found it very important to document new things in the 2nd commit well so other people can start using it.

Closes #132391

welp, apparently also broke clippy... 1s

jdonszelmann · 2025-01-24T20:55:37Z

actually; wrong again: I already worked out this was going to break clippy in november so asked @GuillaumeGomez to help and fix it but it seems the change hasn't landed yet (rust-lang/rust-clippy#13658)

note: compiler compiles but librustdoc and clippy don't document find_attr! better
