// Load X2 with 0x1234FEDC4F5D6E3A first using MOV and MOVK
_start:	MOV	X2, #0x6E3A
	MOVK	X2, #0x4F5D, LSL #16
	MOVK	X2, #0xFEDC, LSL #32
	MOVK	X2, #0x1234, LSL #48

// Just move W2 into W1
	MOV	W1, W2

// Now lets see all the shift versions of MOV
// This does not appear to work with the clang assembler
//	MOV	X1, X2, LSL #1	// Logical shift left
//	MOV	X1, X2, LSR #1	// Logical shift right
//	MOV	X1, X2, ASR #1	// Arithmetic shift right
//	MOV	X1, X2, ROR #1	// Rotate right

// Repeat the above shifts using the Assembler mnemonics.

	LSL	X1, X2, #1	// Logical shift left
	LSR	X1, X2, #1	// Logical shift right
	ASR	X1, X2, #1	// Arithmetic shift right
	ROR	X1, X2, #1	// Rotate right

// Example that works with 8 bit immediate and shift
	MOV	X1, #0xAB000000	// Too big for #imm16

// Example that can't be represented and results in an error
// Uncomment the instruction if you want to see the error
//	MOV	X1, #0xABCDEF11	// Too big for #imm16 and can’t  be represented.

// Example of MVN
	MOVN	W1, #45

// Example of a MOV that the Assembler will change to MVN
	MOV	W1, #0xFFFFFFFE	// (-2)

// Setup the parameters to exit the program
// and then call the kernel to do it.
	MOV     X0, #0		// Use 0 return code
	MOV     X16, #1		// System call number 1 terminates this program
	SVC     #0x80		// Call kernel to terminate the program
