What is argument push order

Question

I\'m learning Assembly language. What exactly is argument push order? i understand its how arguments are pushed to the stack but what does the left and right part mean? left or

Answer 1

The processor knows no 'function arguments'. Therefore when you want to write f(a,b,c), you really need to push the arguments 'somewhere'.

This is convention. I know that on most x86 machines, function arguments are pushed on the stack from right to left, i.e. first c, then b, then a.

push c
push b
push a
call f

Now the called function can use ebx -1 for a, ebx - 2 for b and ebx - 3 for c.

You could as well establish a convention that says: first two arguments are in registers ebx and ecx, rest are on the stack. As long as the caller and callee agree, you're fine.
