Macros

[GUAN DE DIO]

Hi everybody,

      I'm making a macro and I need to load the value of a register into a local macro variable.

      I try several way, the last try has been this:

             Index = rsp

     How can I do this?

Best Regards,

hi,

it is impossible what are you trying to do. Macros are expand before masm assemble your program, so macro-variables exist only at assembly-time - not at run-time!

what should your macro do ?

Thanks for the request.

    I'll do it in a different way.

    I do not why my 64 bits program runs without problem in WinXP64 and in Vista 64 I have stack alignment problem when I call an API.

    With this macro I`ll try to detect if the stack is wrong and fix it making an additional push before the calling

Guan, you might be interested in this way of automatic stack alignment, invented by Jeremy Gordon:

The code to achieve the alignment is ugly and size-consuming, but works well.

It could be done automatically at compile time if you keep tracking of all PUSH/POP instructions and if you follow specific model of code arrangement, but still, it woud be complicated to code all neccessary macros.

Thanks

    This code is very similar to my code, but that is more optimized
