Hazardous

Hazardous is a compiled programming language.
It runs by translating the source code to fasm (flat assembler) instructions, which is then compiled to an object file using fasm. GCC is used to link the object files since I don't know how to make a proper linker (Tried really hard and got nowhere).

This is a project I totally forgot about. As of this writing it's been sitting on my computer untouched for 3 years.

Inefficient
If you happen to look at the generated assembly, you'll see that it utilizes the stack a lot, which may be very inefficient. I wasn't able to figure out how to generate actual good assembly code so I just resorted to a stack model like some interpreted languages do.

Here's a simple Hello World program written using Hazardous.

%include "std.hz"

proc main(argc: i32, argv: u8**) -> i32 {
    printf("Hello World\n");
    return 0;
}

If you look at the following generated assembly you'll see what I'm talking about. You can imagine how inefficient this can be for large programs.

    ; pop it into rcx (x64 calling convention)
    pop rcx

Self-hosted
I planned for Hazardous to be self-hosted, and you can see in the repo that there was some progress made in that area before I eventually slowly stopped working on Hazardous.

Will I ever finish this?
I would like to finish Hazardous some day as I did already put a lot of hours into it. When I decide to start working on it again, I might redo it all from scratch because I literally can't fully grasp the system again.
