Hi Ruifeng, 
I see the following warning when compiling with GCC 12

cc1: warning: switch '-mcpu=neoverse-n2' conflicts with '-march=armv8.5-a+sve2+crypto' switch

Removing 'armv8.5-a' from the list makes the warning go away but what's the correct march for neoverse-n2?
Armv9.0-a is not a supported march flag in GCC.
