Technical tradeoffs

  • Using stub implementations for missing language items allows progress on higher-level components, but full implementation is required for complete functionality.
  • Compiling the 'core' module as a separate library is cleaner but currently blocked by complex trait bounds, necessitating a temporary submodule approach with its own drawbacks.

Rust: Compiling the alloc crate - Status Report 4

Enes Cevik provides the fourth status report on compiling Rust’s alloc crate using GCC’s Rust compiler (GCCRS). Progress includes completing the alloc testsuite, enabling compilation up to name resolution with a mock core module, and identifying four missing language items: ‘range_inclusive_new’, ‘pin’, ‘unpin’, and ‘unsafe_cell’. The immediate priority is to fully implement these, while also working to compile the mock core module as an external library.
