Apologies, my experience is SysV-centric for amd64, as described here[0] under the Parameter Passing section, which is a clustrfuck compared to the simplicity of the 386 SysV ABI as described here[1]: > Argument words are pushed onto the stack in reverse order (that is, the > rightmost argument in C call syntax has the highest address), preserving the > stack’s word alignment. All incoming arguments appear on the stack, resid- > ing in the stack frame of the caller.
