Supported in ARMv8.2 and later.
Usage
Floating-point move immediate (vector). This instruction copies an immediate floating-point constant into every element of the SIMD and FP destination register.
Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the current Security state and Exception level, an attempt to execute the instruction might be trapped.
