Hallo

I have experimented with a programming language called Julia. The language has a function/macro that outputs the generated assembler code of a function.

I can't really do anything with it, but maybe it helps anyway.

An example of how it works can be found here
https://github.com/andizk4kx/raylib-playground/tree/main/raylib_julia
(filename: nativecode.jl)

The result looks like this, for example:

       .text 
        .file   "DrawCircleV" 
        .globl  julia_DrawCircleV_667           # -- Begin function julia_DrawCircleV_667 
        .p2align        4, 0x90 
        .type   julia_DrawCircleV_667,@function 
julia_DrawCircleV_667:                  # @julia_DrawCircleV_667 
; Function Signature: DrawCircleV(Main.Vector2, Float64, Main.Color)
