• riscv-pk

Prerequisites

Debian-like, Ubuntu

• LLVM
  • apt install libssl-dev ninja-build -y

CentOS-like, CentOS 7

• LLVM
  • isl IMPORTANT!!!
    • wget ftp://gcc.gnu.org/pub/gcc/infrastructure/isl-0.18.tar.bz2
    • tar -jxvf isl-0.18.tar.bz2 && cd isl-0.18
    • ./configure && make -j48 && make install
    • echo "export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH" >> ~/.bashrc
  • GCC 7 (use scl)
    • yum install centos-release-scl -y
    • yum install devtoolset-7 -y
    • scl enable devtoolset-7 bash
    • source /opt/rh/devtoolset-7/enable
    • echo "source /opt/rh/devtoolset-7/enable" >> ~/.bashrc
  • CMake 3.13.4+ (required by LLVM)
    • yum install openssl openssl-devel -y
    • git clone https://github.91chi.fun/https://github.com/Kitware/CMake && cd CMake
    • ./bootstrap && make
    • make install
  • Ninja
    • re2c
      • git clone https://github.91chi.fun/https://github.com/skvadrik/re2c && cd re2c
      • autoreconf -i -W all
      • mkdir .build && cd .build && ../configure && make -j48 && make install
    • ninja
      • git clone https://github.91chi.fun/https://github.com/ninja-build/ninja && cd ninja
      • python3 configure.py --bootstrap
      • [cp ninja /usr/bin] (or other path)

Getting Started

Installation path

By default, the installation path is ./riscv_install (RISCV_INSTALL) and llvm-project/install

Auto

It may take 30+ minutes for a high-performance computer.

python3 install_riscv_toolchain.py auto

All repos ({linux} {elf} {elf-rvv} {llvm}) will be downloaded and built without interruption

Semi-auto

python3 install_riscv_toolchain.py all

All repos ({linux} {elf} {elf-rvv} {llvm}) will almost automatically except some downloading selections.

Partially

python3 install_riscv_toolchain.py {linux} {elf} {elf-rvv} {llvm}

• linux for riscv64-linux-unknown-gnu
• elf for riscv64-unknown-elf
• elf-rvv for riscv64-unknown-elf with rvv
• llvm for LLVM clang

Manually

python3 install_riscv_toolchain.py then follow the prompts

• Choose build target from riscv64-linux-unknown-gnu, riscv64-unknown-elf, riscv64-unknown-elf with rvv, LLVM
• Clone riscv-gnu-toolchain, riscv-isa-sim (spike), riscv-pk or not
  • If clone, submodules in riscv-gnu-toolchain update (qemu will be removed)
• Waiting for the compiling

Example

python3 install_riscv_toolchain.py elf elf-rvv

This will automatically install spike, pk, riscv64-unknown-elf-toolchain and riscv64-unknown-elf-toolchain(with rvv) in ./riscv_install/{elf, elf-rvv}.

Options in the script

• RISCV_INSTALL, the installation path
• NUM_CORES, the number of cores for your CPU
• *_REPO urls, in case you have unlimited github access
• LLVM_BUILD_TOOL and LLVM_BUILD_BIN, if no ninja is installed

ISSUES

• The modules failed to update in riscv-gnu-toolchain
  • Remove the whole repo and re-clone may be a fast way
