[nsd-users] Run-time effects of new SIMD code

[Anand Buddhdev]

Hi NSD developers,

I've been following recent discussion and activity around building NSD
4.10, triggered by build failure in Homebrew. I see that you added some
code to detect more things and adjust the build based on what type of
processor is detected.

If one were to build NSD on an x86_64 CPU with Haswell architecture, and
then run this build on another x86_64 CPU that doesn't have that
architecture, will NSD not run, or will it crash, or will it silently use
sub-optimal code?

Regards,
Anand
