Syntax

NEG Wd, Wm{, shift #amount} ; 32-bit general registers

Equivalent to SUB Wd, WZR, Wm {, shift #amount}.

NEG Xd, Xm{, shift #amount} ; 64-bit general registers

Equivalent to SUB Xd, XZR, Xm {, shift #amount}.

Where:

Wd

Is the 32-bit name of the general-purpose destination register.

Wm

Is the 32-bit name of the general-purpose source register.

amount

Depends on the instruction variant:

32-bit general registers

Is the shift amount, in the range 0 to 31, defaulting to 0.

64-bit general registers

Is the shift amount, in the range 0 to 63, defaulting to 0.

Xd

Is the 64-bit name of the general-purpose destination register.

Xm

Is the 64-bit name of the general-purpose source register.

shift

Is the optional shift type to be applied to the second source operand, defaulting to LSL, and can be one of LSL, LSR, or ASR.
