Hi,
Is there any plan to support AES on 32 bits ARM arm7 (NEON)?
I am using ARM armv7(NEON) 32 bits cross compiler, but 1.6.2 failed to compile.
It seems zerotier-one AES is using armv8 instructions.
Thanks
Hello.
Can you post the error messages?
I don’t think arm7 NEON supports the necessary instructions to use hardware AES.
Hi zt-travis,

our cross compiler is arm7v 32 bits with NEON support. So ARM_NEON is defined by the cross compiler.
but instructions
vrbitq_u8
vaeseq_u8
are armv8 instructions.
