|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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]>

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]>
