Exploring the Rust Compiler: GCC vs LLVM

Exploring the Rust Compiler: GCC vs LLVM

The Rust compiler uses a borrow checker to optimize code performance and memory management. Rust code is compiled using the official compiler rustc. rustc uses LLVM optimizations on the backend to convert high-level Rust code into low-level machine code. However, a new GCC frontend called gccrs has recently emerged as an alternative to the rustc … Read more
