RISC-V GNU Toolchain

Purpose: The project provides a RISC-V C and C++ cross-compiler that can build bare-metal ELF or Linux ELF toolchains.
C libraries: Bare-metal builds can use Newlib or Picolibc, while Linux builds can use glibc, musl, or uClibc.
Architecture and ABI: The build defaults to RV64GC and supports RV32 or RV64 configurations with selectable architecture extensions and ABIs.
Multilib: Multilib builds can target both 32-bit and 64-bit systems, and are supported for Newlib and Linux/glibc toolchains.
LLVM integration: LLVM can be built alongside the toolchain with the --enable-llvm configure flag, but LLVM and multilib configuration flags cannot be combined.
Simulation: The project documents QEMU, GDB, and experimental Spike simulator options for running tests, with simulator support varying by toolchain.
Testing: The repository includes DejaGNU test support, and documents make check targets for GCC, Binutils, and glibc on Linux toolchains.
Build requirements: The README says a build downloads about 200 MiB of upstream sources and needs about 8 GiB of disk space; cloning the repository takes around 6.65 GB.
Platforms: The README provides build instructions for Linux distributions and macOS, including Apple Silicon; it also discusses Linux subsystem or Cygwin builds on Windows.
Who it is for: The README describes its development section as intended for developers, advanced users, or people building with their own source trees.
Support channel: The repository provides an issue tracker and pull request interface on GitHub.
License: The repository has a LICENSE file containing licensing terms for the project and its included components.
What it does: It is a RISC-V C and C++ cross-compiler that builds bare-metal ELF or Linux ELF toolchains.
Bare-metal libraries: Bare-metal builds can use Newlib or Picolibc.
Price from: Free
