Call a non-existent macro in a function body. ``` fn main() { foo!(); } ``` 2. No diagnostics are raised. An unresolved-macro-call diagnostic is expected. 3. If the macro call is instead outside of the function body, this works as expected. I believe this worked previously and regressed in https://github.com/rust-analyzer/rust-analyzer/pull/7805. **Behavior prior to https://github.com/rust-analyzer/rust-analyzer/pull/7805:** - The unresolved-macro-call diagnostic did not exist. Instead, a macro-error diagnostic would be raised with the text "could not resolve macro [path]". - This was implemented by adding an error to the error sink (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8L657). - The error was propagated through https://github.com/rust-analyzer/rust-analyzer/blob/1a82af3527e476d52410ff4dfd2fb4c57466abcb/crates/hir_def/src/body.rs#L123 eventually reaching https://github.com/rust-analyzer/rust-analyzer/blob/1a82af3527e476d52410ff4dfd2fb4c57466abcb/crates/hir_def/src/body/lower.rs#L569. **Behavior after:** - Instead of writing to the error sink, an UnresolvedMacro error is now returned (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8R631). - The parent caller throws away the error as its function signature is `Option<MacroCallId>` (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8R604). - We instead now reach the warn condition (https://github.com/rust-analyzer/rust-analyzer/blob/1a82af3527e476d52410ff4dfd2fb4c57466abcb/crates/hir_def/src/body.rs#L124) and no diagnostics are created in https://github.com/rust-analyzer/rust-analyzer/blob/1a82af3527e476d52410ff4dfd2fb4c57466abcb/crates/hir_def/src/body/lower.rs#L575. **Fix:** - Make sure to propagate the UnresolvedMacro error. Report the error using the new unresolved-macro-call diagnostic. Co-authored-by: Brandon <[email protected]>

I used this [test case](https://github.com/weiznich/minimal_example_for_rust_81262) (for `features(32-column-tables)`) to run following command to benchmark: ``` time rust-analyzer analysis-stats --load-output-dirs ./ ``` Before this PR : 2 mins After this PR: 3 seconds. However, for 64-column-tables cases, we still need 4 mins to complete. I will try to investigate in the following weeks. bors r+ Co-authored-by: Edwin Cheng <[email protected]>

|\ | | | | | | | | | | | | | | | | | | 7359: ItemTree: store a mapping from blocks to inner items r=jonas-schievink a=jonas-schievink To do name resolution within block expressions, we need to know which inner items are located inside each block expression. This adds such a mapping to `ItemTree`, replacing the previous one, which was seemingly unused other than to access all the inner items. This also assigns `AstId`s to block expressions, which is needed to store the mapping in salsa. Co-authored-by: Jonas Schievink <[email protected]>

| | | | | | | | | | Every block expression may contain inner items, so we need to be able to refer to any block expression and use it as a salsa key.

Instead of storing the whole `ExpansionInfo`, we store a similar but stripped version `HygieneInfo`. 2. Instread of storing the `SyntaxNode` (because every token we are interested are IDENT), we store the `TextRange` only. 3. Because of 2, we now can put it in Salsa. 4. And most important improvement: Instead of computing the whole frames every single time, we compute it recursively through salsa: (Such that in the best scenario, we only need to compute the first layer of frame) ```rust let def_site = db.hygiene_frame(info.def.file_id); let call_site = db.hygiene_frame(info.arg.file_id); HygieneFrame { expansion: Some(info), local_inner, krate, call_site, def_site } ``` The overall speed compared to previous PR is much faster (65s vs 45s) : ``` [WITH old PR] Database loaded 644.86ms, 284mi Crates in this dir: 36 Total modules found: 576 Total declarations: 11153 Total functions: 8715 Item Collection: 15.78s, 91562mi Total expressions: 240721 Expressions of unknown type: 2635 (1%) Expressions of partially unknown type: 2064 (0%) Type mismatches: 865 Inference: 49.84s, 250747mi Total: 65.62s, 342310mi rust-analyzer -q analysis-stats . 66.72s user 0.57s system 99% cpu 1:07.40 total [WITH this PR] Database loaded 665.83ms, 284mi Crates in this dir: 36 Total modules found: 577 Total declarations: 11188 Total functions: 8743 Item Collection: 15.28s, 84919mi Total expressions: 241229 Expressions of unknown type: 2637 (1%) Expressions of partially unknown type: 2064 (0%) Type mismatches: 868 Inference: 30.15s, 135293mi Total: 45.43s, 220213mi rust-analyzer -q analysis-stats . 46.26s user 0.74s system 99% cpu 47.294 total ``` *HOWEVER*, it is still a perf regression (35s vs 45s): ``` [WITHOUT this PR] Database loaded 657.42ms, 284mi Crates in this dir: 36 Total modules found: 577 Total declarations: 11177 Total functions: 8735 Item Collection: 12.87s, 72407mi Total expressions: 239380 Expressions of unknown type: 2643 (1%) Expressions of partially unknown type: 2064 (0%) Type mismatches: 868 Inference: 22.88s, 97889mi Total: 35.74s, 170297mi rust-analyzer -q analysis-stats . 36.71s user 0.63s system 99% cpu 37.498 total ``` Co-authored-by: Edwin Cheng <[email protected]>
