[PATCH 00/22] target/arm: Implement fp16 for AArch32 VFP |

This patchset implements fp16 support for AArch32 VFP.
I've included the final "turn it on in -cpu max" patch for
convenience for testing, but we shouldn't commit that until
we've also added AArch32 Neon fp16 support. (I have a patchset
for that in progress, but I still have a handful of insns still to
convert; I figured I'd send this lot out for review rather than
waiting and sending a 50-patch set that covered VFP and Neon.)
I'll send out the risu patch that adds patterns for fp16
insns in a moment.
thanks
