Assembly++ is a simplified version of x86-64 assembly

To use Assembly++ you need to have a file with the extension .asmpp and you have to have NASM installed on your computer. To compile the file you have to run the following command in the terminal:

asmpp -f <format> -o <output file name> <input file name>

The syntax is very similar to x86-64 assembly, but with some differences. Here is an example of a simple program that prints out a triangle of asterisks:

include "std.asmpp"

global _start

section .data
    star: "*"
    newline: "\n"


fn _start() 
{
    xor r12 , r12 
    while (r12  lt 10){
        xor rbx, rbx
        while (rbx lt r12){
            call print(star, len(star))
            add rbx, 1
        }
        call print(newline, len(newline))
        add r12, 1
    }


    call exit(EXIT_SUCCESS)
}
