MOVAPD

Moves aligned packed single-precision floating-point values from a source to a destination.

The following table covers what the source and destinations can be.

DO NOT support LOCK

The instruction REQUIRES that both the source and destination memory operands be aligned on a 16-byte boundary. If the memory operand is not aligned, a general-protection exception (#GP) SHALL be generated.

To avoid #GP exceptions, the programmer MUST ensure that memory addresses used with MOVAPD are 16-byte aligned. If alignment cannot be guaranteed, MOVUPS SHALL be used instead.
