- assembly - writing functions in assembler - Stack OverflowI am writing code in assembler (nasm) and I want to include functions, at the moment I have. function0: code jmp return0 the function is called with a jump to function0 with the return linking to a label below where the function is called, however this only works if the function is called once, is there a better way to do this?
- How do I start learning Assembly - Stack OverflowWrite simple programs in C and then compile them with the -S switch. you will get a file.s containing the assembler code. Tinker with it and you will learn it. The best part is that if you want to learn a different assembler, you can just compile gcc as cross compiler, and produce assembler for any supported platform.
