Re: PUSH & POP question

[daydreamer]

it would be nice to make use of the real stack, instead of a fake one when it comes to SIMD regs,so how do I change this code to make use of EBP to put it on real stack?
printing .xmm regs would be easy to "push" on stack and 4 unrolled calls to print that

.data?
    statestack  dd 0 dup (65536)
                dd 0 dup (65536)
.code
;ebx is initialized to make use of statestack



PUSHSTATE MACRO
    FXSAVE [ebx]
    add ebx,512
    ENDM
    POPSTATE MACRO
    sub ebx,512
    FXRSTOR [ebx]
   
    ENDM
;macro is on purpose written without spacebar to avoid conflict with keyword PUSH/POP
PUSHXMM1 MACRO
    movaps [ebx],xmm1
    add ebx,16
    ENDM
POPXMM1 MACRO
   movaps xmm1,[ebx]
   sub ebx,16
   ENDM

Your macros are nice, but you could simply declare local OWORD variables (you need a modern assembler like UAsm).

P.S.: I couldn't resist - Push & Pop xmm registers (thanks for the inspiration ;))

thats great idea for macros JJ
its old macros from 2006
you missed my earlier posting January
