Odroid-C2 7.90.009: NEON Disabled [Solved]

Not sure if this really is a bug/oversight or is intentional (maybe it doesn't work while enabling NEON?), but at the top of the KODI log it says:

Code

06:20:11.779 T:547591626752  NOTICE: ARM Features: Neon disabled

Not that enabling NEON in the KODI build would noticeably improve performance, wouldn't enabling it be better than not enabling it?

EDIT: Upon doing more digging, I ran across a merged PR from a month ago that kind of explains why neon is disabled. Here is a couple commented lines that were included in the change from the PR:

Code

# change this to --enable-neon when AArch64 NEON performance is improved
		+  # check performance with test/benchbitslice

It seems to suggest NEON introduces a performance regression when enabled.
