README

        
A locally optimising Javalette compiler written in C. Javalette is

essentially a subset of C, without pointers and dynamic memory

allocation.

Features

--------

* Two backends: 32bit x86 assembly and quadruple code.

* Liveness analysis.

* Register allocation with Belady's algorithm.

* Local basic block optimisations: constant folding, common

  subexpression elimination, copy propagation.

* Frame pointer omission optimisation.

Requirements

------------

* Linux

* bison

* flex

* nasm assembler to produce x86 executables

Usage

-----

* Compilation: `make`

* Tests: `make test`

* Invocation: `jl [options] program.jl`

* Help: `jl -h`

* Examples: [`tests/examples`](tests/examples)

Before running the compiler ensure that the `JL_DATA_DIR` environment

variable is set appropriately, or use the `-d` option. The

`JL_DATA_DIR` variable should point to the `data` directory in the

source package.

Documentation

-------------

A more detailed documentation is available in [`doc/doc.pdf`](doc/doc.pdf) (in Polish).
