By: Derek Tan / DrkWithT at GitHub

Requirements:

• Editor: any one that works on Unix / Unix-like systems!
• VCS: Git
• System: Linux distro, MacOS, BSD variant, etc.

Summary:

This repo contains sample programs written in GNU Assembly. The list below gives brief information on the code and its usage. Here, I assume that the reader is new to using GNU make with GNU assembly code.

Programs:

1. test1.s: Tells whether a hardcoded 32-bit integer is greater than 10 or not.
2. write_hex.s: Prints a hardcoded word value in hex representation.
3. dec_to_hex.s: Gets a 4 digit decimal number and then prints the hex representation.

Assembling:

• The command to build a single, one file program is make ./bin/<source file name>.out.
• The command to clear out old executables is make clean.
