ycc: x86-64 C Compiler written in C

ycc is a self-hosted x86-64 C Compiler written in C.

This is initially based on https://www.sigbus.info/compilerbook (compilerbook).
I create this compiler for my study :)

Disclaimer

This is partially compliant with C11 specification.
The implementation is work in progress, so ycc is still a toy.

Prerequisite

• Docker
• x86-64 Environment

Preparation

1. $ docker build -t compilerbook https://www.sigbus.info/compilerbook/Dockerfile

How to build

1. $ ./shell.sh
2. $ make

Varieties

You can use 1st, 2nd and 3rd gen compilers.

Path	Gen	Description
./build/ycc_gen1	1st	Compiled by cc
./build/ycc_gen2	2nd	Compiled by ./build/ycc_gen1
./build/ycc_gen3	3rd	Compiled by ./build/ycc_gen2 (Same as gen2)

How to use

1. $ ycc <target C file path> (output the assembly to stdout)

How to test

1. $ ./test-docker.sh

Difference from compilerbook

• Self-hosted
• Struct
• Enum
• Variable Arguments
• short, _Bool and void type
• typedef
• Function declaration
• switch
• Scope
• char literal
• continue and break
• %, ||, &&, +=, !, ++ and -- operators
• and so on!

Todo
