Store HIR attributes in a side table Same idea as #72015 but for attributes. The objective is to reduce incr-comp invalidations due to modified attributes. Notably, those due to modified doc comments. Implementation: - collect attributes during AST->HIR lowering, in `LocalDefId -> ItemLocalId -> &[Attributes]` nested tables; - access the attributes through a `hir_owner_attrs` query; - local refactorings to use this access; - remove `attrs` from HIR data structures one-by-one. Change in behaviour: - the HIR visitor traverses all attributes at once instead of parent-by-parent; - attribute arrays are sometimes duplicated: for statements and variant constructors; - as a consequence, attributes are marked as used after unused-attribute lint emission to avoid duplicate lints. ~~Current bug: the lint level is not correctly applied in `std::backtrace_rs`, triggering an unused attribute warning on `#![no_std]`. I welcome suggestions.~~ |
