RustyBamboo / LLVM-c

A simple c-style language using menhir, ocamllex, and LLVM

About

The language is similar to the one implemented in https://gnuu.org/2009/09/18/writing-your-own-toy-compiler/. It is a c-like syntax with additional support for int and double and treats the last expression as the return value for a function. The main function must be defined as part of the language. The printf takes in one argument, checks the type, and uses the C printf to print (with newline).

The following is an example to calculate volume of cylinder:

double circle(double r) {
    3.14 * r * r
}

double cyl(double r, double h) {
    h * circle(r)
}

int main() {
    double vol = cyl(2.0, 5.0)
    printf(vol)
    0
}
