Zhinx Extension
Synopsis
The Zhinx extension provides analogous half-precision floating-point instructions. The Zhinx extension depends upon the Zfinx extension. The Zhinx extension adds all of the instructions that the Zfh extension adds, except for the transfer instructions FLH, FSH, FMV.H.X, and FMV.X.H. The Zhinx variants of these Zfh-extension instructions have the same semantics, except that whenever such an instruction would have accessed an f register, it instead accesses the x register with the same number.
