*hust* Wie bestellt ist hier auch schon der neue Code *g*

Delphi-Quellcode:
class procedure TProceduren.RunMethod(AMethod: String;
  Params: array of Const);
var proc: Pointer;
    hi: Integer;
    i, off: Integer;
    param: Byte;
begin
  proc := MethodAddress(AMethod);
  hi := High(Params);
  asm
    mov param,0
    mov i,0
    @loop:
      mov eax,i
      cmp eax,hi
      jg @loopend
        imul eax,i,8
        add eax,4
        mov off,eax
         
        mov eax,[Params]
        add eax,off
        movzx ax,byte ptr [eax]
         
        cmp ax,vtExtended
        je @EditParam
          inc param
          cmp param,2
          jle @NextLoop
        @EditParam:
          sub off,4
          cmp ax,vtExtended
          jne @NoExt
            mov eax,[Params]
            add eax,off
            mov eax,[eax]
            movzx edx, word ptr [eax+$08]
            push edx
            push [eax+$04]
            push [eax]
            jmp @NextLoop
          @NoExt:
            mov eax,[Params]
            add eax,off
            push [eax]
        @NextLoop:
          inc i
          jmp @loop
    @loopend:

    mov param,0
    mov i,0
    @loop2:
      mov eax,i
      cmp eax,hi
      jnl @loop2end
        imul eax,i,8
        add eax,4
        mov off,eax
        
        mov eax,[Params]
        add eax,off
        mov eax,[eax]

        cmp eax,vtExtended
        je @NextLoop2
        inc param

        cmp param,1
        je @edx
        cmp param,2
        je @ecx
        jmp @loop2end

        @edx:
          sub off,4
          mov eax,[Params]
          add eax,off
          mov edx,[eax]
          jmp @NextLoop2
        @ecx:
          sub off,4
          mov eax,[Params]
          add eax,off
          mov ecx,[eax]
          jmp @Loop2End
      @NextLoop2:
        inc i
        jmp @loop2
    @loop2end:

    mov eax,self
    call proc
  end;
end;
Int64's werden jedoch noch nicht unterstützt. Ich arbeite aber daran
