anybody working on ARM Cortex support?

Is anybody actively working on additional ARM target support?

I need Cortex support (ARMv7, VFPv3, and Neon).

Thank you.

Since there have been no answers, I will have to start at the beginning.

One of the first changes I'd like to try is adding the additional
registers and the AAPCS VFP variant calling conventions. Is there a
reason why the ARM Target isn't using the CCState machinery?

Please clarify. I am not sure what you mean by CCState machinery.

The ARM Target doesn't use the class CCState. For example,
CCState.AnalyzeCallOperands, CCState.AnalyzeCallReturn,
CCState.AnalyzeReturn, etc. There is no ARMCallingConv.td as there is
for other targets. All calling convention decisions are made manually.

If there is no reason not to, it might simplify adding the AAPCS
Standard Variants like AAPCS-AFP, etc. since they'll be defined with
TableGen and therefore more readily extended.
