As shown in the screenshot above， there are always building erros when i use some NEON Instruction in float16_t type(such as vaddq_f16)~
I suspect it is ARMRAL_ARCH_COMPILE_OPTIONS issues which need i to modify "-march=armv8-a+crypto" CACHE INTERNAL ".
I tried many methods and the compilation error still exists。
Can anybody tell me how to resolve this erros?
Thanks a lot!!
Hello again.On a second look at the error message, it appears that there is a possibility your target architecture may not be compatible with the ACLE vaddq_f16 accumulation function, which compiles to FADD in NEON, or even vmulq_f16 for that matter. This is because half precision floating point intrinsics were only enabled from ArmV8.2-A ISA onwards. Make sure that you have the required target architecture and if that is indeed the case, you can go ahead and use either of -mcpu/-march =native.Meanwhile I am running a diagnosis and trying to reproduce the error on my end.
