Compare function consuming time, intrinsics function in CLA versus function in CLAmath library

float __meinvf32(float) is intrinsics function.

it 's supported by CLA compiler.

it can be called to get result of 1/x.

float CLAdiv( float fNum, float fDen) or CLAdiv.asm in CLAmath library also can be called to get result of fNum/fDen.

which function costs less time?

 __meinvf32(x) or CLAdiv( 1.0, x)?
