CCaml

A toy C compiler written in OCaml.

Usage

Let's print Hello, World!.

$ dune exec ccaml examples/valid/hello_world.c | gcc -xassembler - && ./a.out
Hello, World!

The examples/valid/hello_world.c program is the following.

int putchar(int c);

int main() {
    putchar(72);
    putchar(101);
    putchar(108);
    putchar(108);
    putchar(111);
    putchar(44);
    putchar(32);
    putchar(87);
    putchar(111);
    putchar(114);
    putchar(108);
    putchar(100);
    putchar(33);
    putchar(10);

    return 0;
}

# Generate assembly
$ dune exec ccaml source.c
# Execute a program with GCC assembler
$ dune exec ccaml source.c | gcc -xassembler - && ./a.out
# Run test
$ dune test
