          hi，I have some doubts about the ```fli``` instruction.

I'm not sure. If the number 0-31 is used instead of the table "Immediate values loaded by the FLI.S instruction", how can this reflect the actual floating point of the load at the instruction level? Is it more appropriate to use fli.h ft1, -1.0 instead of fli.h ft1, 0?

As I explained earlier, this is not the right place to talk about this (since I only implement draft Zfa specification of riscv/riscv-isa-manual). After the Zfa extension is changed, I will consider changing it.
