Compliance​

All GNU MCU Eclipse RISC-V Embedded GCC releases are based on the official RISC-V source files maintained by SiFive.

The current version is based on the following commits:

Improvements​

All architectures, ABIs and libraries supported by the riscv64-unknown-elf toolchain are also supported, with the following improvements:

  • a newer newlib was included, which supports the 'underscore' syscall functions
  • the mandatory reference to libgloss in the linker configuration was removed
  • the march=rv32imaf/mabi=ilp32f library was added to the list of multi-libs
  • support for newlib-nano was added
  • the standard documentation, in PDF and HTML, was added

Binaries​

Binaries for Windows, macOS and GNU/Linux are provided.

The GNU/Linux binaries were built on two CentOS 6 Docker images (32/64-bit), and run on any distribution based on CentOS 6 or later.

The Windows binaries were built with mingw-w64, and run on any reasonably recent i686 and x86_64 Windows machines.

Instructions on how to install the binaries are available in the project README.

The toolchain is also available as an xPack and can be conveniently installed with xpm:

xpm install --global @gnu-mcu-eclipse/riscv-none-gcc

This installs the latest available version.

For better control and repeatability, the build scripts use Docker containers; all files required during builds are available as a separate gnu-mcu-eclipse/riscv-none-gcc-build project.

Known problems​

  • none
