[$] Rust and GCC, two different ways

Developers working in languages like C or C++ have access totwo competing compilers - GCC and LLVM - either of which can usually getthe job done. Rust developers, though, are currently limited to theLLVM-based rustc compiler. While rustc works well, thereare legitimate reasons for developers to wish for an alternative. As itturns out, there are two different ways to compile Rust using GCC underdevelopment, though neither is ready at the moment. Developers of bothapproaches came to the 2021 LinuxPlumbers Conference to present the status of their work.
