Remove the borrow check::nll submodule #66886

mark-i-m · 2019-11-30T01:50:50Z

NLL is the only borrow checker now, so no need to have a separate submodule.

Also, just grepping, it looks like there are a lot of context structs in use in the rustc_mir::borrow_check module. Can any of these be merged (I suspect at least the region error reporting stuff can be)?

MirBorrowckCtxt               // from rustc_mir::borrow_check
BorrowCheckContext            // from rustc_mir::borrow_check::type_check
LivenessContext               // from rustc_mir::borrow_check::type_check
RegionInferenceContext        // from rustc_mir::borrow_check::region_infer
ErrorReportingCtx             // from rustc_mir::borrow_check::diagnostics:region_errors
RegionErrorNamingCtx          // from rustc_mir::borrow_check::diagnostics::region_naming

// From rustc::mir::visit
TyContext
MutatingUseContext
NonMutatingUseContext
NonUseContext
PlaceContext

// From rustc::infer
InferCtxt

// From rustc::ty
TyCtxt

ErrorReportingCtx can be replaced with MirBorrowckCtxt by not reporting those errors until the MirBorrowckCtxt is constructed.

…=matthewjasper Refactorings to borrowck region diagnostic reporting This PR is a followup to rust-lang#66886 and rust-lang#67404 EDIT: updated In this PR: Clean up how errors are collected from NLL: introduce `borrow_check::diagnostics::RegionErrors` to collect errors. This is later passed to `MirBorrowckCtx::report_region_errors` after the `MirBorrowckCtx` is created. This will allow us to refactor away some of the extra context structs floating around (but we don't do it in this PR). `borrow_check::region_infer` is now mostly free of diagnostic generating code. The signatures of most of the functions in `region_infer` lose somewhere between 4 and 7 arguments :) Left for future (feedback appreciated): - Merge `ErrorRegionCtx` with `MirBorrowckCtx`, as suggested by @matthewjasper in rust-lang#66886 (comment) - Maybe move the contents of `borrow_check::nll` into `borrow_check` and remove the `nll` submodule altogether. - Find a way to make `borrow_check::diagnostics::region_errors` less of a strange appendage to `RegionInferenceContext`. I'm not really sure how to do this yet. Ideas welcome.
