The benchmark is pointless however way you
look at it.

Android is built using gcc, and this benchmark
doesn't compare the builds of the system
software directly.

It doesn't matter for application developers,
because native code is only recommended for
isolated routines called from Java code. And
the last thing any programmer would do is
disable NEON.

And as you said, the benchmark can't even
produce proper assembler code which allows one
to see the speed of certain instruction mixes
or memory access patterns. So its useless for
writing optimized assembler, too.

A lot of hot air, no meat.
