On ARM, a SIMD register is the exact same as two floating point register. So you can be just lucky sometimes that unrelated fp operations can use SIMD registers. And if you pick the registers then your chances are good. If you have a loop using two fp additions you can quite likely choose registers so you can use a SIMD instruction.
