Zfinx extension[1] had already finished public review. Here is the
implementation patch set that reuse floating point pattern and ban
the use of fpr when use zfinx as a target.
Current works can be find in follow links, will keep update zhinx
and zhinxmin soon after zfh/zfhmin implemented in gcc.

https://github.com/pz9115/riscv-binutils-gdb/tree/zfinx-rebase
For test you can use qemu or spike that support zfinx extension, the
qemu will go upstream soon and spike is still in review:
https://github.com/plctlab/plct-qemu/tree/plct-zfinx-dev
https://github.com/plctlab/plct-spike/tree/plct-upstream-zfinx
Thanks for Tariq Kurd, Kito Cheng, Jim Willson,
Jeremy Bennett helped us a lot with this work.
