In oe-core, there are definitions for various tunings that use the ARM EABI w/
HF extension.
The following tunings support that mode: (And armhf is avsolutely not required
to be for the armv7-a CPU.. it compatible with any CPU that supports VFP
instructions... note there are armv7-a systems that do -not- have VFP support,
so these ABI extensions will not work there!)
armv5ehf-vfp armv5tehf-vfp
armv5ehfb-vfp armv5tehfb-vfp
armv5hf-vfp armv5thf-vfp
armv5hfb-vfp armv5thfb-vfp
armv6hf armv6thf
armv6hfb armv6thfb
armv7hf armv7thf armv7hf-neon armv7thf-neon
armv7ahfb armv7athfb armv7ahfb-neon armv7athfb-neon
armv7hf armv7thf armv7hf-neon armv7thf-neon
armv7hfb armv7thfb armv7hfb-neon armv7thfb-neon

Hello,
do we already have support for the ARM "armhf" ABI in OpenEmbedded? (A quick
search on the ML didn't get me hits).
Basically,"armhf" is built with -mfloat-abi=hard, and tuned for armv7-a CPUs.
