Ah, I didn't notice that it varied according to which assembler is
being used. What I saw was this:
#ifdef CL_X86_ASM_STYLE
__asm {
mov eax, oper;
mov edi, cpuid_ptr;
cpuid;
mov [edi], eax;
mov [edi+4], ebx;
mov [edi+8], edx;
mov [edi+12], ecx;
};
which definitely stashes them into memory in order EAX/EBX/EDX/ECX,
which corresponds to the comment. I'm not familiar with the other
syntax, which uses =a, =r, =c, =d, but since you switched those, I'm
assuming they correspond to the Accumulator, Result??, Counter, and
Data registers.
Thanks!
