## What it is
AMaCC is a small, from-scratch C compiler targeting 32-bit Arm (armv7hf) that can execute code via a JIT compiler or generate ELF executables for GNU/Linux. It supports a C89 subset sufficient for self-hosting and is designed as a pedagogical tool for learning compilers, linkers, and loaders.

## Use cases
- learn how compilers, linkers, and loaders work
- compile a subset of C on a Raspberry Pi
- study JIT compiler implementation for Arm
- generate ELF executables from C source
- explore self-hosting compiler design
- teach compiler construction with a minimal codebase

## When to choose
- you want a tiny, readable compiler codebase for education
- you target 32-bit Arm Linux on Raspberry Pi
- you need a self-hosting C compiler example with JIT and ELF modes

## When to avoid
- you need full C89/C99 compliance or production-grade optimization
- you target x86, 64-bit Arm, or non-Linux platforms
- you need struct assignment, typedef, or type qualifiers

## Facets
- artifact type: library
- maturity: active
- function: compiler, interpreter, parser, developer-tools
- domain: compilers, programming-languages, education, embedded-systems
- platform: cpp, cli
- tags: c-compiler, jit-compilation, elf-generation, self-hosting, arm32, pedagogical, raspberry-pi, linux, arm
