VC Compiler
VC is a compiler written in Java that converts a C-like language into Jasmin assembly. This was a university assignment I completed for UNSW's Programming Languages and Compilers course. Although the project framework and some utility code was provided as starter code, the scanner, parser, checker and emitter were all programmed by me.
Scanner and parser
The compiler uses a top-down parser to tokenise input files and generate an abstract syntax tree.
Static analyser
The VC programming language is a strongly-typed programming language. During compilation, my compiler checks for numerous errors, including:
- Redeclared identifiers
- Identifiers with the
voidtype - Undeclared identifiers
- Incompatible types for
return, variable assignment and operators - Invalid types in array initializers
- Non-boolean types for
ifandwhilestatements - Incorrect function calling signature
- Unreachable code
Code-gen
The compiler outputs files in the Jasmin assembly format. These are then assembled into Java bytecode.
