Make local query providers receive local keys by compiler-errors · Pull Request #109092 · rust-lang/rust

compiler-errors · 2023-03-13T19:40:33Z

When a query is marked separate_provide_extern, we can map a query key to a "local" form of the key, e.g. DefId -> LocalDefId. This simplifies a ton of code which either has to assert or use something like expect_local to assert that the query key is local.

Overall result: ❌✅ regressions and improvements - ACTION NEEDED

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please fix the regressions and do another perf run. If the next run shows neutral or positive results, the label will be automatically removed.

Noise? 🤔

cjgillot

What a great cleanup!

cjgillot · 2023-03-18T10:39:17Z

Why a separate trait instead of your initial implementation using the Key trait?

So that the as_local_key only has to be provided for the keys where we actually make use of it. This should make it a little easier to make sure that all of the impls are correct and not run into things like #109109 again.

Yeah, exactly what Nils said.
