gccrs: Name resolve external types
GCC's Rust compiler adds name resolution for external type items.
GCC’s Rust compiler now includes name resolution logic for ExternalTypeItem. This enhancement allows the compiler to correctly resolve and handle type definitions that are declared as external, ensuring proper integration with other parts of the Rust compilation process. A new test case verifies this functionality.
In Details
The gccrs TopLevel name resolver has gained a new visitor method, visit(ExternalTypeItem), in its 2.0 implementation. This addition specifically targets the name resolution of items declared as ExternalTypeItem. This is crucial for correctly mapping and validating external type declarations within the Rust module system, ensuring that the compiler can correctly refer to and process types defined outside the current compilation unit.
- name resolution
- The process by which the compiler determines what identifier (like a variable or function name) refers to. It involves looking up names in scopes and namespaces.
- ExternalTypeItem
- A specific construct within GCC's Rust frontend representing a type that is declared externally, meaning its definition resides in another module or crate.
- module system
- Rust's system for organizing code into logical units (modules and crates) and controlling visibility and dependencies between them.
