Our ARM chip don't support the NEON instruction, can you supply a non-NEON

openSUSE doesn't support soft-float ARM configurations.
It's still hard-float, but without NEON.
We used to have builds that worked fine without NEON, as Tegra 2
lacked support for it. But the Tegra 2 was a non-ARM implementation,
while this chip should hopefully be ARM Cortex based.
Are you 100% sure that there is no NEON support on that chip?
If yes, we can try to revive compatibility with non-NEON-compatible
cores, but I'm not incredibly fond of the idea, since all ARM Cortex
cores should have NEON support.
Ummm...
Didn't all the distros agree on VFP3-D16 (i.e. hard-float, non-NEON)
as the baseline for cross-distro compatibility for the ARM hard-float
ports?
The idea behind the cross-distro compatibility was to standardize on the
ABI and ABI requirements. IIUC these are identical whether you use NEON
instructions or not.
The fact that code may be compiled with NEON optimizations enabled is
thus not an issue of cross-distro compatibility :). It only narrows down
the set of hardware that we can run on.
