Compiler

An extremely simple C compiler for MARIE (Machine Architecture that is Really Intuitive and Easy).

Limitations

• Only a small subset of C features is supported. It is still far from being able to compile a real-world program without modifications.
• The compiler is still at a very early stage and many bugs can happen during parsing or code generation.
• MARIE architecture supports 4K words of memory, which is a big limitation for the amount of instructions a program can have and how much space can be destined to the stack.

Features

• Data types int and char
• Arithmetic operators +, -, *, /, %, ++ and --
• Relational operators ==, !=, <, <=, > and >=
• Logical operators && and ||
• Pointer operators * and &
• Flow control statements if, while and for
• Function calls working (recursion is supported)
• Initial support for macros and typedef
• { } syntax to initialize arrays
• "" syntax to initialize strings

Requirements

The project uses Yarn for the dependencies, so make sure you have Yarn and Node.js installed on your machine:

• Yarn: https://yarnpkg.com/
• Node.js: https://nodejs.org/

Installation

1. Clone the repository and navigate to the project folder:

git clone https://github.com/lsmacedo/c-compiler-marie
cd c-compiler-marie

2. Install the dependencies:

yarn install

Usage

To compile a .c file, use the yarn compile command with the file names. Example:

yarn compile hello.c world.c

The following parameters are supported:

• -o <file>: Output file name (default: a.mas)
• -v: verbose mode

The generated MARIE code is written by default into the file a.mas and can be executed in a simulator like this one: https://marie.js.org/
