|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 7994: Speed up mbe matching in heavy recursive cases r=edwin0cheng a=edwin0cheng In some cases (e.g. #4186), mbe matching is very slow due to a lot of copy and allocation for bindings, this PR try to solve this problem by introduce a semi "link-list" approach for bindings building. 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]>

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]>
