The road to compiling the standard library with gccrs
summary
Project claims to compile the Rust 1.49 standard library and actually builds large parts of core and alloc while hitting concrete gaps: declarative macro expansion and macro name resolution, const generics already present in core, unimplemented format_args so println! still broken, many missing GCC intrinsics, and no borrow checker yet. Implementation is a C++ reimplementation of rustc front end totalling 200,000 lines of C++ with three paid developers and about a dozen volunteers; some crates compile, many fail.
