The Rust compiler team announced two new groups: a GPU target notification group staffed by experts from AMD, Nvidia, and Intel to help diagnose GPU-related issues, and a Linker working area focused on integrating alternative linkers such as Wild into the compiler.
mold 3.0.0, a high-performance drop-in replacement for Unix linkers, has been released. Benchmarks show it links 4.9x faster than LLVM lld and 1.9x faster than wild at the median, with broad architecture support.
mold is a massively parallel linker that reduces link times by applying data parallelism across all passes, achieving 2.4–16.1x faster performance than state-of-the-art linkers like lld.
The article explores the limitations of GCC's large code model (mcmodel=large), particularly its inability to handle Thread Local Storage (TLS) with 32-bit relocations, making it unusable for truly large binaries despite its stated purpose.
The new Zig ELF linker now supports fast incremental compilation with external libraries and C sources, enabling rebuilds in milliseconds on x86_64 Linux.
Epic Games open-sources the RAD Debugger, a native Windows user-mode graphical debugger, along with the RAD Debug Info (RDI) format and the high-performance RAD Linker for x64 PE/COFF binaries optimized for huge projects with multi-gigabyte debug info.
