assembly-things

A couple of small programs I wrote in x86_64 assembly for Linux

• hello-world.asm: Prints Hello, World! to stdout
• hello-world-c.asm: Links to libc to print Hello, World!
• fizzbuzz.asm: A FizzBuzz program
• cat.asm: Prints files. Can concatinate multiple files. If there are no arguments, prints from stdin.
• is-even.asm: Exit with 0 or 1 depending on the number provided being even or odd

Build:

$ yasm -f elf64 -o cat.o cat.asm  # assemble with assembler
$ ld -o cat cat.o                 # link with linker
$ ./cat cat.asm                   # and it can print its own source code
