Riscv Gnu Toolchain
This project is a cross-compiler toolchain for RISC-V software development. It provides the necessary components to compile C and C++ source code into executable binaries and libraries specifically for the RISC-V hardware architecture.
The toolchain supports multi-architecture binary generation and multilib capabilities, allowing a single installation to target various instruction set specifications and bit-widths. It integrates with alternative compilers such as LLVM and Clang and includes a bootstrapped build pipeline to produce high-performance versions of the tools.
The system covers broad capability areas including embedded systems compilation and cross-platform deployment for Linux and macOS. It also incorporates system emulation and hardware simulation to validate toolchain logic and execute compiler test suites without requiring physical hardware.
