Extensible Firmware Interface Specification
19-40 12/01/02 Version 1.10
BEHAVIORS AND RESTRICTIONS:
• Specifying an Operand 1 index when Operand 1 is direct results in an instruction encoding
exception.
• The Operand 2 index is sign extended to the size of the move if necessary.
• If the Operand 2 index size is smaller than the move size, then the value is truncated.
• If Operand 1 is direct, then the Operand 2 value is sign extended to 64 bits and stored to the
Operand 1 register.
