I do like this:

Code:

macro Im chX,chY { local l1,l2,l3
                   comiss  chX,xmm0
                   jb      l1
                   comiss  chY,xmm0    ;xmm2
                   jb      l2
                   maxss   chX,chY
                   jmp     l3
               l1: comiss  chY,xmm0
                   jae     l2
                   minss   chX,chY
                   jmp     l3
               l2: addss   chX,chY
               l3:
                 }
macro ApplyC {
               movss   xmm1,dword [eax]
               movss   xmm2,dword [ebx]
               movss   xmm3,dword [edx]
               movss   xmm4,dword [ebp]
               Im      xmm1,xmm2
               Im      xmm3,xmm4
               Im      xmm1,xmm3
               movss  [edi],xmm1
               movss  [edi+4],xmm1
               add     edi,8
               add     ebp,8
               add     eax,8
               add     edx,8
               add     ebx,8
             }
