A compiler implemented for the MiniJava language as part of the DD2488 (komp14) course at KTH, Royal Institute of Technology.

The compiler supports jasmin assembler output for the Java Virtual Machine as well as ARM assembler and experimental support for X86_64. Future versions is also expected to contain a JavaScript backend for execution in a web browser or Node.js (or similar).

Run ant all to build the compiler. It will

1. fetch dependencies
2. build the compiler
3. package it into a JAR file and
4. run a testcase to verify the build.

The compiler comes with some test cases used in the course. It is by no means a complete test suite, but it catches many of the obvious bugs a compiler can experience. The tests are divided into 4 groups

• compile - Expected to compile, but no demands on ability to execute.
• noncompile - Should fail during compilation. Syntax and semantical errors are here.
• execute - Code that both compiles and executes. Comes with a file containing expected outputs.
• nonexecute - Code that should compile, but results in various errors during execution. Like a stack overflow or invalid memory access.
