// DIVSS - Divide Scalar Single Precision Floating-Point Values
// DIVSD - Divide Scalar Double Precision Floating-Point Values
//
// DIVSS divides the low single-precision (32-bit) floating-point value
// DIVSD divides the low double-precision (64-bit) floating-point value
// Upper bits are preserved from the first source operand
//
// Opcodes:
// F3 0F 5E /r             DIVSS xmm1, xmm2/m32     - Divide scalar single in xmm1 by xmm2/m32
// F2 0F 5E /r             DIVSD xmm1, xmm2/m64     - Divide scalar double in xmm1 by xmm2/m64
