=====

Simple Virtual Machine written in Haskell.

## About

hs-vm is based on a stack machine architecture.

## Status

experiment phase

## Usage

To run example just:

```

cabal sandbox init

cabal configure --enable-tests

cabal install --enable-tests --only-dependencies

cabal build

./dist/build/hs-vm/hs-vm example/fib.hsvm

```

To test it:

```

cabal build && cabal test

```

hs-vm's instructions are in `src/VM/Instruction.hs`.

All label setting instructions are executed in preprocess phase.

A valid hs-vm program has `main` function. To set main function, use `Label main`.

To define function, use `Label func_name`. To return to calling point, use `Ret`.

hs-vm stacks Local Data Stack when calls a function.

And when returned from function, hs-vm pops back stacked one.
