Hi.

I wrote following code and got a wrong result:
Code:
proc tep x
   invoke wsprintf,buf,fmt,[x] ; x equ ebp+10h, but [ebp+10h] is undefined!
    ret
endp
    


So, I see the two ways to correct it: manually filling stack parameters area from registers or fix proc macro to implement copying parameters to the stack, e.g.
Code:
proc tep x
   ; prologue begin
    push rbp
    mov  rbp,rsp
        mov  [x],rcx   ; real copy parameters
       virtual at rcx ; or just aliasing it
          x dq ?
    end virtual
 ; prologue end

  invoke wsprintf,buf,fmt,[x] ; well, [x] is correct
  ret
endp
    


It would be better, if real copying block can be optional, for optimization purposes.
