SSE4a

SSE4a is a set of 4 SIMD instructions introduced in AMD K10 microarchitecture:

• EXTRQ - extracts a set of bits from a register.
• INSERTQ - inserts a set of bits located in source register into a destination register.
• MOVNTSS - writes register's lower 32 bits into memory using non-temporal hint (cache is not updated and data is written directly to memory).
• MOVNTSD - writes register's lower 64 bits into memory using non-temporal hint (cache is not updated and data is written directly to memory).
