pentium IV (matrix instructions)

Could I use the newest Intel PIV instructions thorugh asembler with VC++.NET
'02?

No. But you can use the compiler supplied intrinsics instead. See

for details.

You should know, there is no instruction that can't be used in the asm
blocks.

There will be in the future (I can't argue one way or the other whether it's
true now). Use the intrinsics - IIUC, no more new instructions will be
supported in inline assembly in future versions of the product.

With emit you can use any instruction :)
and...you should be able to emit dw,dd,dq not just db :(
In fact, why not just leave the suport for the db,dw,etc.. in the asm
blocks? :((

And if I where to want to optimize something to such extent as to use
MMX/SSE/etc.. I don't think I'd want to use the intrinsics...

Actually you do:

- Already, the compiler is able to schedule the instructions emitted by the
intrinsics, possibly ordering them better then you can by hand.
- This is where the efforts of Intel & Microsoft are being directed -
they'll only get better.
