MazuCC
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.
Build
Run make to build:
$ make
MazuCC comes with unit tests. To run the tests, give "check" as an argument:
$ make check
MazuCC is known to work on both GNU/Linux and macOS.
Use MazuCC to compile C source:
$ ./mzcc sample/nqueen.c
Alternatively, 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.s
If MazuCC is compiled and executed on macOS, the above argument -no-pie
should be eliminated.
Reference output of MazuCC-compiled sample/nqueen:
Q . . . . . . .
. . . . Q . . .
. . . . . . . Q
. . . . . Q . .
. . Q . . . . .
. . . . . . Q .
. Q . . . . . .
. . . Q . . . .
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.
