x86_to_RISCV

An x86 to RISC-V JIT Binary Translator

Setup

Cloning the Repository

git clone --recurse-submodules https://github.com/matinraayai/x86_to_RISCV/
cd x86_to_RISCV/zydis
git checkout master
cd dependencies/zycore
git submodule init && git submodule update

Note: If encountered an "unsupported distribution" error from Zydis' header, simply go to Defines.h file located at zydis/dependencies/zycore/include/Zycore and make the header define ZYAN_X64 regardless of the target ISA and comment out the 'error "Unsupported architecture detected"'.

Building the emulator for RISC-V

This has been tested on Ubuntu 18.04 LTS. For installation on other distros please visit each project's repository. 0. Dependencies:

sudo apt-get install autoconf automake autotools-dev curl libmpc-dev \
libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf \
libtool patchutils bc zlib1g-dev libexpat-dev make gcc g++ cmake

1. Build the RISC-V Toolchain and set it up in your path:

git clone --recursive https://github.com/riscv/riscv-gnu-toolchain
# You can change prefix to any other directory without space in its name.
./configure --prefix=/opt/riscv
sudo make -j $(nproc) linux
# export variables
export PATH="$PATH:/opt/riscv64/bin"
export RISCV="/opt/riscv64"

2. Build the translator's binary:

cd build_riscv/
cmake .
make

3. Build the guest's binary:

cd build_x86/
cmake .
make

Running the Emulator on AMD64 Using the riscv64-unknown-linux-gnu-run Tool from the RISC-V Toolchain:
