4 weeks ago Hi, there are indeed various possible workarounds, including setting HWY_DISABLED_TARGETS=HWY_NEON_BF16.
I'm curious what the issue was? GCC 9.4 aarch64 seems to work. We don't enable HWY_NEON_BF16 prior to GCC 13.2.
The error is as follows. It seems that my system architecture does not support fp16. Is it possible to turn off fp16 through compilation options?
