GNU binutils for RISC-V and Sparc/LEON

This project contains scripts and patches for downloading and building patched GNU binutils for RISC-V and Sparc architectures with added new instructions.

binutils version

This package uses and modifies binutils v2.37.

Building for Sparc

Run script './run_sparc.sh all' to build binutils for Sparc/LEON target. The compiled tools are placed in subdirectory 'install-sparc'.

Building for RISC-V

Run script './run_riscv.sh all' to build binutils for RISC-V target. The compiled tools are placed in subdirectory 'install-riscv'.

Using

Add the output directory with the compiled tools for RISC-V architecture to the PATH.

export PATH=<repository>/install-riscv/bin:${PATH}

or fot Sparc architecture

export PATH=<repository>/install-sparc/bin:${PATH}

New assembler instructions can be used with options '--has-swar','--has-fhalf','--has-fcplx','--has-fpack' for Sparc architecture. For RISC-V architecture new instructions can be used if the input assembler file contains corresponding CPU extension in the archiutecture attribute.

All compiled binutils tools have prefix 'riscv64-daiteq-elf-' for RISC-V architecture and 'sparc-daiteq-elf-' for Sparc architecture.
