|\ | | | | | | | | | | | | | | | | | | 8285: Don't recheck obligations if we have learned nothing new r=matklad a=flodiebold This is just the most trivial check: If no inference variables have been updated, and there are no new obligations, we can just skip trying to solve them again. We could be smarter about it, but this already helps quite a bit, and I don't want to touch this too much before we replace the inference table by Chalk's. Fixes #8263 (well, improves it quite a bit). Co-authored-by: Florian Diebold <[email protected]>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 8201: Fix recursive macro statements expansion r=edwin0cheng a=edwin0cheng This PR attempts to properly handle macro statement expansion by implementing the following: 1. Merge macro expanded statements to parent scope statements. 2. Add a new hir `Expr::MacroStmts` for handle tail expression infer. PS : The scope of macro expanded statements are so strange that it took more time than I thought to understand and implement it :( Fixes #8171 Co-authored-by: Edwin Cheng <[email protected]>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 7907: Autoderef with visibility r=cynecx a=cynecx Fixes https://github.com/rust-analyzer/rust-analyzer/issues/7841. I am not sure about the general approach here. Right now this simply tries to check whether the autoderef candidate is reachable from the current module. ~~However this doesn't exactly work with traits (see the `tests::macros::infer_derive_clone_in_core` test, which fails right now).~~ see comment below Refs: - `rustc_typeck` checking fields: https://github.com/rust-lang/rust/blob/66ec64ccf31883cd2c28d045912a76179c0c6ed2/compiler/rustc_typeck/src/check/expr.rs#L1610 r? @flodiebold Co-authored-by: cynecx <[email protected]>

|\ \ \ | |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | 8133: Ignore type bindings in generic_predicates_for_param (fix panic on ena and crates depending on it) r=flodiebold a=flodiebold This allows us to handle more cases without a query cycle, which includes certain cases that rustc accepted. That in turn means we avoid triggering salsa-rs/salsa#257 on valid code (it will still happen if the user writes an actual cycle). We actually accept more definitions than rustc now; that's because rustc only ignores bindings when looking up super traits, whereas we now also ignore them when looking for predicates to disambiguate associated type shorthand. We could introduce a separate query for super traits if necessary, but for now I think this should be fine. Co-authored-by: Florian Diebold <[email protected]>
