For example (in C):

double putchard(double c) {
    return (double)putchar((double)c);
}

Just a few utilities that aren’t expressible in the native Kaleidoscope code.

Right now, we have no way to generate a value main definition.

I think I want to solve this by requiring a def main() with zero parameters. Then during codegen we can special-case main and generate it to return an int (maybe casting the function body’s result?). That way we can actually execute the resulting code.

As I work (#5) on adding a putchard (that just casts to int and calls putchar) and printd (that calls to printf("%f", value)), it would be nice to be able to express these natively as some sort of extended Expression (instead of writing them each by hand as I am now).

I don’t want to add types to the Kaleidoscope language itself, just augment the parsed expressions with types and add the ability to construct other-typed expressions in code.

Depends on #7

I’m… not exactly sure how to unit test code generation. Just rely on LLVM doing the right thing and cross my fingers?

Should explain how to get LLVM.swift building. And how to run the output.

Depends on bencochran/KaleidoscopeLang#9
