compiler's Introduction

Compiler

This is a part of Java OS project. It compiles the Java Bytecode to native machine code for x86 processor.

Build

Run following command to get the source code:

git clone git://s55969da3.adsl.online.nl/jx/compiler.git

This is a NetBean projecct.

compiler's Issues

create a new java project from GUI

default in interface doesn't work well

bytecode compiler for different processors

working in progress:

x86 processors
arm processors

found out the difference between int and float settings

try to add long support. (see issue os#14)

change vector to hashmap

too many empty elements inside the vector

all programming languages to json format

JSON syntax rules are simple and consistent. Data is in name/value pairs, separated by commas. Curly braces hold objects, and square brackets hold arrays. Strings are in double quotes, and numbers are without quotes. Booleans are represented by true or false, and nulls are represented by null. Whitespace can be inserted between any tokens to improve readability

use compact arrays

the size of each element inside the arrays is fixed: 32bits. for bytes and shorts

a list of java projects

compiler button

synchronized key word doesn't compile

GUI for the compiler

compile output not continues

save a project

release build

use a different way to find out whether this is lib zero
