This commit introduces support in gccrs for compiling Rust’s platform-intrinsic functions, which map to specific SIMD (Single Instruction, Multiple Data) hardware instructions. It generates GIMPLE code for various intrinsic operations like comparisons, arithmetic, and bitwise operations, ensuring these are compiled with the cdecl ABI. This enables gccrs to handle Rust code that leverages specialized SIMD capabilities for performance.
