When we need to emit a lint at a macro invocation, we currently use the `NodeId` of its parent definition (e.g. the enclosing function). This means that any `#[allow]` / `#[deny]` attributes placed 'closer' to the macro (e.g. on an enclosing block or statement) will have no effect. This commit computes a better `lint_node_id` in `InvocationCollector`. When we visit/flat_map an AST node, we assign it a `NodeId` (earlier than we normally would), and store than `NodeId` in current `ExpansionData`. When we collect a macro invocation, the current `lint_node_id` gets cloned along with our `ExpansionData`, allowing it to be used if we need to emit a lint later on. This improves the handling of `#[allow]` / `#[deny]` for `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` and some `asm!`-related lints. The 'legacy derive helpers' lint retains its current behavior (I've inlined the now-removed `lint_node_id` function), since there isn't an `ExpansionData` readily available. |
