azcc: Azarashi2931's C Compiler

This is a toy C compiler, developed at seccamp2020.

Enviroment

• Linux on x86_64 CPU
• Cygwin on x86_64 CPU

Requirement

• GNU C Compiler
  • For pre-processing, assembling, linking and running some tests.
• GNU Make
  • For building and running tests.
• POSIX like shell
  • For running some test shell scripts.

How to Build and Test

• make: build 1st generation azcc.
• make test1: build and run tests for 1st generation azcc, which is built by gcc, clang, or such other C Compiler.
• make test2: build and run tests for 2nd generation azcc, which is built by 1st generation azcc.
• make test3: build and run tests for 3rd generation azcc, which is built by 2nd generation azcc.
• make test-all: build and run tests for all generation azccs.
• make clean: remove binaries.
• make all: run make clean and make test-all.

Usage

Basic

Makefile outputs bin/genX/azcc(X is the generation of azcc).
After running make command, you can do the following:

$ cpp source.c > source.i
$ bin/genX/azcc source.i > source.s
$ gcc -o source.out source.s

or

$ cpp source.c | bin/gen1/azcc - | gcc -xassembly -o source.out -

Advanced

You can cross-compile by adding target option.
For example, when you want to compile Cygwin binary on Linux, like the following:

$ cpp source.c > source.i
$ bin/genX/azcc source.i --targt=amd64-w64-windows-gnu > source.s
$ gcc -o source.out source.s
