I want to port some neon instructions to accelerate my code.
can anyone show me some examples how to use neon in VIM3?
I tried adding -mfpu=neon, but failed in platform gcc.
Thanks,

btw, I am using ubuntu VIM3 system.
pls show any errors, its better to use intrinsics for implementing NEON instructions, please do read upon this forum post:

thanks for your reply.
Here is command line with g++ system provided:
g++ -std=c++11 -mcpu=cortex-a73 -mfpu=neon -c test.cpp
and error as below :
g++: error: unrecognized command line option ‘-mfpu=neon’
