MazuCC is a minimalist C compiler with x86_64 code generation. It is intended to support partial C99 language features while keeping the code as small and simple as possible.
Run make to build:
$ makeMazuCC comes with unit tests. To run the tests, give "check" as an argument:
$ make checkMazuCC is known to work on both GNU/Linux and macOS.
Use MazuCC to compile C source:
$ ./mzcc sample/nqueen.cAlternatively, MazuCC accepts the stream from standard input. The equivalent form for the above command is:
$ cat sample/nqueen.c | ./mzcc -You will get the generated x86_64 assembly in AT&T syntax. The output can be assembled and linked into a valid executable:
$ ./mzcc -o sample/nqueen.s sample/nqueen.c
$ gcc -no-pie -o sample/nqueen sample/nqueen.sIf MazuCC is compiled and executed on macOS, the above argument -no-pie
should be eliminated.

Alternatively, you can dump internal abstract syntax tree:
echo 'struct {int x; char y; struct { int t; } z; } a;' | ./mzcc --dump-ast -The expected output in S-expression form:
(decl (struct (int)
(char)
((struct (int)))) a)
MazuCC is heavily inspired by 8cc.
