tVM

tVM is a very simple stack-based virtual machine meant to educate how a language VM works.

tVM only supports arithmetic operations. The input to tVM is a .bc file containing a comma-separated list of bytecodes and the output is the result of executing the bytecodes (either interpreted or JIT-compiled).

The "JIT compiler" in tVM is a simple x86-64 code generator that translates tVM bytecodes into corresponding machine encoding.

Getting started

This page contains some basic instructions to get you started.

1. Requirements

• git
• cmake 3.2 or above
• C/C++ compiler toolchain

2. Clone this repository

git clone https://github.com/b9org/tVM.git

3. Create build directory

mkdir build \
&& cd build

4. Configure and build

cmake .. \
&& make

5. Run

From the build directory, run:

./tvm-run/tvm-run ../test/simple_add.bc

The command above would run simple_add.bc in interpreter mode. To JIT-compile the program and running the compiled code, run with -jit option:

./tvm-run/tvm-run -jit ../test/simple_add.bc
