SSE2 Miscellaneous Instructions

The SSE2 instructions described below provide additional functionality for caching non-temporal data when storing data from XMM registers to memory, and provide additional control of instruction ordering on store operations.

Table 3–44 SSE2 Miscellaneous Instructions


Solaris Mnemonic	Intel/AMD Mnemonic	Description	Notes
`clflush`	`CLFLUSH`	flushes and invalidates a memory operand and its associated cache line from all levels of the processor's cache hierarchy
`lfence`	`LFENCE`	serializes load operations
`maskmovdqu`	`MASKMOVDQU`	non-temporal store of selected bytes from an XMM register into memory
`mfence`	`MFENCE`	serializes load and store operations
`movntdq`	`MOVNTDQ`	non-temporal store of double quadword from an XMM register into memory
`movnti`	`MOVNTI`	non-temporal store of a doubleword from a general-purpose register into memory	`movntiq` valid only under `-xarch=amd64`
`movntpd`	`MOVNTPD`	non-temporal store of two packed double-precision floating-point values from an XMM register into memory
`pause`	`PAUSE`	improves the performance of spin-wait loops
