my sample MessageBoxA:

Code:

data  dd 0,text1,text2,0
text1 db 'Hello !',0
text2 db 'Message:',0

movups xmm1,[data]
sub  esp,16
movups dqword [esp],xmm1
call [MessageBoxA]

This SSE code fast in 1.6 unlike four Pushs ! I tested on Intel I5(2320) 3Ghz
How to write a macro that would consider how much to take parameters for function ?

I know about invoke. Invoke done pushs as much as write parameters !
I need new macro for SSE ! I mean macro like invoke, but for xmm register, not for push

Macro must calculate how sub from esp and how do movups\movsd\movd.
I mean if need 6 parameters for function and macro must generated like this code:

Code:

movups xmm1,[data]
movsd   xmm2,qword [data+16]
sub  esp,24 
movups dqword [esp],xmm1
movsd qword [esp+16],xmm2 
call [SomeFunction]

What if the data is in registers?

Code:

invoke Function,eax,edi,ebx,ecx

I want to make regardless function, from registers ! If i long time not programming, then hard read and understand code when using registers. And i spend many times when i read old code.
I have standart and this standart make more easily read my code.
But you revolution leaving from my problems ! Smile
