Improve documentation of MIR queries & passes #1434

Jaic1 · 2022-08-16T11:32:22Z

This PR improve the documentation of MIR queries and passes.

Below is the summary of changes:

delete mir_validated
add mir_promoted and mir_drops_elaborated_and_const_checked
replace the NoLandingPads pass example with CleanupNonCodegenStatements
extend the stealing mechanism and give the dependency of MIR queries as an overview
add mdbook-mermaid in the build instructions

FIXME:

Does ty::queries::foo::force(...) still appear in rustc?

Since rust-lang/rust#99102 may significantly change the MIR queries (and thus its doc), we can wait for its result or send follow-up PRs. This is mostly documenting the code in rustc_mir_transform, so maybe cc @rust-lang/wg-mir-opt.

with rust-lang/rust#99102 now accepted, does this need to change

Jaic1 · 2022-09-05T06:51:39Z

Yes, the doc in this PR need to change to reflect the recent changes in rust-lang/rust#99102. But we could wait a minute until it gets more stable and complete since the MIR phases and semantics there, I think, are under overhaul.

rust-lang/rust#99102 has been merged :)

@oli-obk Could you help with the review here or ping relevant folks?
@Jaic1 Could you resolve the merge conflict meanwhile?

I'm not sure what's the current status of this PR, but would be great if we merge something about it, thoughts?.

Jaic1 · 2024-06-30T03:07:49Z

Sorry for the late reply, I had been busy with my master project for the last few years.

I just refined the MIR passes doc and resolved the git conflicts.

Jaic1 · 2024-06-30T03:10:04Z

cc @spastorino, could you help me find some reviewers?

oli-obk · 2024-07-09T08:06:15Z

Please rebase so there are no more merge commits

Done.

Looks good to me but I'd leave the merge up to @oli-obk who knows better about MIR than me.
