Floating-point Negate (scalar). This instruction negates the value in the SIMD and FP source register and writes the result to 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.
