INSTRUCTION SET REFERENCE
DIVSSĀScalar Single-FP Divide
Description
The DIVSS instructions divide the lowest SP FP numbers of both operands; the upper three
fields are passed through from xmm1.

Operation
DEST[31-0]= DEST[31-0] / (SRC/m32[31-0]);
DEST[63-32]= DEST[63-32];
DEST[95-64]= DEST[95-64];
DEST[127-96]= DEST[127-96];
Intel C/C++ Compiler Intrinsic Equivalent
__m128 _mm_div_ss(__m128 a, __m128 b)
Divides the lower SP FP values of a and b; the upper three SP FP values are passed through from
a.
Exceptions
