MOV (wide immediate)

Move (wide immediate) moves a 16-bit immediate value to a register.

This is an alias of MOVZ. This means:

313029282726252423222120191817161514131211109876543210

32-bit (sf == 0)

MOV <Wd>, #<imm>

is equivalent to

MOVZ <Wd>, #<imm16>, LSL #<shift>

and is the preferred disassembly when ! (IsZero(imm16) && hw != '00').

64-bit (sf == 1)

MOV <Xd>, #<imm>

is equivalent to

MOVZ <Xd>, #<imm16>, LSL #<shift>

and is the preferred disassembly when ! (IsZero(imm16) && hw != '00').

Assembler Symbols

<Wd>

Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field.

<Xd>

Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field.

<imm>

For the 32-bit variant: is a 32-bit immediate which can be encoded in "imm16:hw".

For the 64-bit variant: is a 64-bit immediate which can be encoded in "imm16:hw".

<shift>

For the 32-bit variant: is the amount by which to shift the immediate left, either 0 (the default) or 16, encoded in the "hw" field as <shift>/16.

For the 64-bit variant: is the amount by which to shift the immediate left, either 0 (the default), 16, 32 or 48, encoded in the "hw" field as <shift>/16.
