Toy Compiler for Cortex-M4

A lightweight C-based compiler targeting the ARM Cortex-M4 architecture. This project is designed to be efficient enough to eventually run as a self-hosted compiler directly on Cortex-M4 hardware.

Current Status

• Target: ARM Cortex-M4.
• Host Build: Windows x64 using GNU GCC.
• Feature Goal: Self-hosting capabilities and direct flashing to hardware.

Syntax & Docs

• Read DOCS.md to gain an idea of how the language works.

Project Files

• main.c
• compiler.c : Main file
• src.m4 : Source code file (can be opened with the custom UDL).
• m4UDL.xml : My language's UDL file for use in notepad++.
• CMakeLists.txt: Build system configuration.
• bld.bat: Standard build script.
• remake.bat: Clean and cache refresh script.
• compile.bat : Command to compile a text file.

Usage

Build and Run

To compile the compiler on Windows (with GCC in path)

First navigate to the repository

cd %pathToRepo%

Compile compiler :)

bld

To compile a source file

compile %sourcePath%

OR:

%directoryOfCompilerExecutable%/CortexM4Compiler.exe %sourcePath%

API used to compile a string

void assembleSource(const char* sourceString, const uint32_t programOrigin)
