Rust Drop trait support in gccrs - Status Report 4
GSoC student reports progress on implementing Rust's Drop trait in GCC, focusing on exception handling.
This is a status report on a Google Summer of Code project to implement Rust’s Drop trait in gccrs, the Rust frontend for GCC. The primary focus has been on refactoring cleanup mechanisms to use TRY_FINALLY_EXPR instead of manual drop calls, with several patches merged or under review. The project also aims to align the gccrs design with rustc’s approach.
- proposer
Reports on progress incorporating Rust's `Drop` trait, including migrating to `TRY_FINALLY_EXPR` for cleanup and updating existing patches based on review feedback.
In Details
gccrs aims to implement Rust language features. This report details progress on Drop trait support, focusing on exception handling semantics within the compiler's intermediate representation. The work involves adapting cleanup strategies to align with GCC's internal expression handling.
- Drop trait
- In Rust, a trait that defines the behavior of objects when they go out of scope, akin to a destructor in C++.
- gccrs
- The Rust frontend for GCC, enabling GCC to compile Rust code.
- TRY_FINALLY_EXPR
- A GCC internal expression type used for structured exception handling, similar to try-finally blocks in other languages.
