from the manual:
Code:
macro jif op1,cond,op2,thelabel
{
        cmp op1,op2
        j#cond thelabel
}    

I made something, call-if, rather than jump-if
Code:
macro cif op1,cond,op2,thelabel
{
        push thelabel#return
        cmp op1,op2
        j#cond thelabel
        add rsp,8
        thelabel#return:
}

new version, only writes to memory if needed
Code:
macro cif2 op1,cond,op2,thelabel
{
        local lab2,lab3
        cmp op1,op2
        j#cond lab2
        jmp lab3
        lab2:
                push lab3
                jmp thelabel
        lab3:
}
