rv32jit

rv32jit is a modern C++-based RISC-V instruction set simulator with a JIT assembler serving as an x86-64 binary translator.

Features

• Fast runtime for executing the RV32 ISA
• Built-in ELF loader
• Implementation of partial Linux system calls

Build and Verify

Currently, only GNU/Linux is supported for building rv32jit.

rv32jit relies on specific third-party packages for full functionality. Please install the following package in advance.

• clang version 15+, which can be downloaded from the LLVM Page.
• libelf-dev

Build the simulator:

$ make

You might receive the message "Please run 'make' again." If you do, simply follow the instruction and run make once more.

Download prebuilt RISC-V ELF files and run:

$ make check
