I think someone said that SDK 2.5 is supposed to support BFI_INT natively,
sounds like it"In SDK 2.5 we are expanding that, along with other optimizations, to generate BFI instructions."
Seems you are wrong (at least for now):
The optimization has been disabled in the current SDK due to a bug in the implementation that didn't get fixed in time.
By the way is there any official Download link for the KernelAnalyzer 1.9?
