FLI.H
ISAFLI.H is a RISC-V floating-point load-immediate instruction defined as part of the Zfa extension. It loads a predetermined 16-bit half-precision floating-point constant into a floating-point register. The instruction is supported by the sail-riscv formal specification.

FLI.H
Overview
FLI.H (Float Load Immediate, Half-precision) is a RISC-V instruction that writes a predefined half-precision (16-bit, FP16) floating-point constant into a floating-point register rd. It is one of the FLI variants defined by the RISC-V Zfa extension, alongside FLI.S (single-precision) and FLI.D (double-precision).
