Intel Description

Empty the MMX state, which marks the x87 FPU registers as available for use by x87 instructions. This instruction must be used at the end of all MMX technology procedures.

Deprecated since version X87: MMX technology intrinsics can cause issues on modern processors and should generally be avoided. Use SSE2, AVX, or later instruction sets instead, especially when targeting modern processors.
