Thanks for alerting me to this. I had tested NEON vectorization on my Raspberry Pi with the 64-bit Manjaro OS. As you say, NEON is much more limited on 32-bit targets, lacking not only vectorized double precision operations, but also some basic single precision operations like division (confirmed when I tried the 32-bit Raspian OS). It doesn't seem worth figuring out what small subset of vectorized floating-point operations I could still support in Adept, so in the latest commit I've disabled vectorization for 32-bit ARM targets.
Great! Thanks for adressing this.
There are missing symbols, some examples:
The issue is that these are only defined in the
arm_neon.h
header for 64 bit targets (__aarch64__
). Is this something that is planned to be fixed? Or should vectorization be disabled for 32 bit arm targets?
