The SSE2 data movement instructions move double-precision floating-point data between XMM registers and memory.

Table 3–36 SSE2 Data Movement Instructions


Solaris Mnemonic	Intel/AMD Mnemonic	Description
`movapd`	`MOVAPD`	move two aligned packed double-precision floating-point values between XMM registers and memory
`movhpd`	`MOVHPD`	move high packed double-precision floating-point value to or from the high quadword of an XMM register and memory
`movlpd`	`MOVLPD`	move low packed single-precision floating-point value to or from the low quadword of an XMM register and memory
`movmskpd`	`MOVMSKPD`	extract sign mask from two packed double-precision floating-point values
`movsd`	`MOVSD`	move scalar double-precision floating-point value between XMM registers and memory.
`movupd`	`MOVUPD`	move two unaligned packed double-precision floating-point values between XMM registers and memory
