The operations listed in the following table are followed by descriptions of each intrinsic.

SSE2 intrinsics use the __m128, __m128i, and __m128d data types, which are not supported on Itanium Processor Family (IPF) processors. Any SSE2 intrinsics that use the __m64 data type are not supported on x64 processors.

The emmintrin.h header file contains the declarations for the SSE2 instructions intrinsics.

Arithmetic Operation Intrinsics

Intrinsic name	Corresponding instruction	Operation	R0 value	R1 value
_mm_add_sd	ADDSD	Adds	`a0 [op] b0`	`a1`
_mm_add_pd	ADDPD	Adds	`a0 [op] b0`	`a1 [op] b1`
_mm_div_sd	DIVSD	Divides	`a0 [op] b0`	`a1`
_mm_div_pd	DIVPD	Divides	`a0 [op] b0`	`a1 [op] b1`
_mm_max_sd	MAXSD	Computes maximum	`a0 [op] b0`	`a1`
_mm_max_pd	MAXPD	Computes maximum	`a0 [op] b0`	`a1 [op] b1`
_mm_min_sd	MINSD	Computes minimum	`a0 [op] b0`	`a1`
_mm_min_pd	MINPD	Computes minimum	`a0 [op] b0`	`a1 [op] b1`
_mm_mul_sd	MULSD	Multiplies	`a0 [op] b0`	`a1`
_mm_mul_pd	MULPD	Multiplies	`a0 [op] b0`	`a1 [op] b1`
