    How to speed up the Rust compiler in September 2026●YhnCultureTelevision2816 min ago

    Nicholas Nethercote has published a new post in his long-running series on improving the performance of the Rust compiler. The article details the ongoing work to cut compile times in the Rust project, which he has contributed to for years. Rust developers are closely following these performance efforts because compilation speed remains one of the language's most common complaints.

    Two ARM64 compiler bugs in GCC and Rust hit curl●Two ARM64-specific compiler optimization bugs, in GCC 15/16 and Rust, hit curlYhn4413 min ago

    Curl maintainer Daniel Stenberg has flagged two ARM64-specific compiler optimization bugs affecting the popular data transfer tool, one involving GCC 15/16 and one in Rust code. The optimizations produce broken output on aarch64 targets, prompting discussion among developers about compiler correctness, testing coverage on ARM64, and how widely deployed builds may be affected.

    Rust builds and checks can be up to twice as fast●Emitting metadata early makes building/checking Rust up to twice as fastYhnScienceSpace Policy15531 min ago

    A new approach to emitting metadata early is reported to make building and type-checking Rust projects up to twice as fast. The claim is drawing attention among developers interested in compiler and toolchain performance, with discussion focused on how the technique works and what speedups it could deliver for large Rust codebases.
