## C-Language Compiler Implementation

A compiler for a subset of the C programming language (written in C++).

See the grammar [here](specification.txt).

This project is an abomination LOL, especially the ICG.

### Project Status

1. - [x] Lexical Analyzer

2. - [x] Syntax Analyzer

3. - [ ] Semantic Analyzer

4. - [x] Intermediate Code Generator (SPIM, ish-done)

5. - [ ] Machine-Independent Code Optimizer

6. - [ ] Code Generator

7. - [ ] Machine-Dependent Code Optimizer

### Project Requirements

1. C++17 (preferably g++)

### Setup

1. Clone the project into your computer.

2. Launch the project by running the `main.cpp` file. It would be easier to run the project using JetBrain's CLION IDE.

3. The test files are found in the `tests` folder.

   - To switch from one testcase to another, you can:

     1. Use the Makefile i.e. `make o f=tests/submitted.c && spim -file out.asm`

     2. or, when directly running the executable, `./main tests/submitted.c && spim -file out.asm`

     3. or, change the name in the test file specifier on the `main.cpp` file
