69 H8SX_SHIFT_NONE
70 The shift cannot be done in a single instruction.

72 H8SX_SHIFT_UNARY
73 The shift is effectively a unary operation. The instruction will
74 allow any sort of destination operand and have a format similar
75 to neg and not. This is true of certain power-of-2 shifts.
76
77 H8SX_SHIFT_BINARY
78 The shift is a binary operation. The destination must be a
79 register and the source can be a register or a constant. */
