Hi,
thanks for the code. This is exactly what I was looking for.
Steinberg have noted on their dev list, that they usually do this
virtually in any dsp application, so I think it has been tested
successfully over the past years. Some other developers stated, they
even don't restore the registers (okay, I think these were Wintel
guys)...
The performance benefit on tight loops can in some cases be probably
around 10%, maybe more if pipeline stalls can additionally be avoided
(or if you use a branching solution to prevent denormalization :-).
I think it's worth testing. (Dunno what happens when/if the 970 or
whatsoever comes into play, though)
Thanks again,
;) Urs
