WLP4 Compiler

This project is a compiler from WLP4 (a small subset of C) to MIPS assembly language. A quick overview of WLP4 can be found here or the full specification, here. The compiler consists of four main components: a scanner, parser, type checker, and code generator. Each component is implemented as a separate C++ program.

Components

• Scanner (smm and scan): Tokenizes the input source code.
• Parser (parse): Analyzes the tokenized input and constructs a parse tree.
• Type Checker (type): Validates the syntax tree against type rules.
• Code Generator (gen): Generates target assembly from the validated syntax tree.

Usage

To compile the project, use the following commands:

make

This will create the following executables:

• smm
• scan
• parse
• type
• gen

Each executable can be run individually, processing the output from the previous stage:

cat example.wlp4 | ./smm | ./scan | ./parse | ./type | ./gen
