CCoscope

Compiler Construction, mixed with a custom language and LLVM Kaleidoscope, brewed together and still not working.

Building

mkdir build && cd build
cmake ..
make

Note: On debian-like systems, compilation may fail due to missing -ledit. This should be detected and reported by cmake's LLVM detection package, but for some reason it it's not, or maybe the debian package for llvm-dev is missing a dependency. Either way installing libedit-dev solves the issue.

Example

.$ cd build/
./build$ cat ../examples/gcd.cco 
fun gcd (a : int, b : int) : int {
    var c : int;
    c := 0;
    while ( a != 0 ) {
        c := a;
        a := b % a;
        b := c;
    }
    return b;
}
./build$ cat ../examples/gcd_main.cco 
extern fun gcd(a : int, b : int) : int;

fun main() : int{
    print(gcd(160,200));
    print(gcd(160,250));
    print(gcd(100,295));
}
