Remove `DefId` from `EarlyParamRegion` #125468

BoxyUwU · 2024-05-23T23:56:56Z

Currently we represent usages of Region parameters via the ReEarlyParam or ReLateParam variants. The ReEarlyParam is effectively equivalent to TyKind::Param and ConstKind::Param (i.e. it stores a Symbol and a u32 index) however it also stores a DefId for the definition of the lifetime parameter.

This was used in roughly two places:

Borrowck diagnostics instead of threading the appropriate body_id down to relevant locations. Interestingly there were already some places that had to pass down a DefId manually.
Some opaque type checking logic was using the DefId field to track captured lifetimes

I've split this PR up into a commit for generate rote changes to diagnostics code to pass around a DefId manually everywhere, and another commit for the opaque type related changes which likely require more careful review as they might change the semantics of lints/errors.

Instead of manually passing the DefId around everywhere I previously tried to bundle it in with TypeErrCtxt but ran into issues with some call sites of infcx.err_ctxt being unable to provide a DefId, particularly places involved with trait solving and normalization. It might be worth investigating adding some new wrapper type to pass this around everywhere but I think this might be acceptable for now.

This pr also has the effect of reducing the size of EarlyParamRegion from 16 bytes -> 8 bytes. I wouldn't expect this to have any direct performance improvement however, other variants of RegionKind over 8 bytes are all because they contain a BoundRegionKind which is, as far as I know, mostly there for diagnostics. If we're ever able to remove this it would shrink the RegionKind type from 24 bytes to 12 (and with clever bit packing we might be able to get it to 8 bytes). I am curious what the performance impact would be of removing interning of Region's if we ever manage to shrink RegionKind that much.

Sidenote: by removing the DefId the Debug output for Region has gotten significantly nicer. As an example see this opaque type debug print before vs after this PR:
Opaque(DefId(0:13 ~ impl_trait_captures[aeb9]::foo::{opaque#0}), [DefId(0:9 ~ impl_trait_captures[aeb9]::foo::'a)_'a/#0, T, DefId(0:9 ~ impl_trait_captures[aeb9]::foo::'a)_'a/#0])
Opaque(DefId(0:13 ~ impl_trait_captures[aeb9]::foo::{opaque#0}), ['a/#0, T, 'a/#0])

r? @compiler-errors (I would like someone who understands the opaque type setup to atleast review the type system commit, but the rest is likely reviewable by anyone)

🤔 also would like to know why those tests no longer ICE. I might be able to investigate tomorrow if you end up not being able to find out why, just lemme kno

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.
