SectorC is a C compiler written in x86-16 assembly that fits entirely within a 512-byte x86 boot sector. It supports a small but usable subset of C, including functions, global variables, control flow, pointers, and inline machine code.
Use cases
- compile C programs that fit in a 512-byte boot sector
- write real programs on bare-metal x86 with no OS
- learn how compilers work at the smallest possible scale
- run C code directly on vintage IBM PC hardware
- explore sizecoding and demoscene-style programming challenges
When to choose
- you need the smallest possible C compiler for boot-sector demos
- you want to write bare-metal x86-16 programs in a C subset
- you are studying compiler design or extreme size optimization
When to avoid
- you need a full-featured, standards-compliant C compiler
- you need modern tooling, optimization, or debugging support
- you are targeting anything other than 16-bit x86 bare metal
