Syntax
SUB
Wd|WSP, Wn|WSP, #imm{, shift} ; 32-bit
SUB
Xd|SP, Xn|SP, #imm{, shift} ; 64-bit
Where:
Wd|WSP- Is the 32-bit name of the destination general-purpose register or stack pointer.
Wn|WSP- Is the 32-bit name of the source general-purpose register or stack pointer.
Xd|SP- Is the 64-bit name of the destination general-purpose register or stack pointer.
Xn|SP- Is the 64-bit name of the source general-purpose register or stack pointer.
imm- Is an unsigned immediate, in the range 0 to 4095.
shift-
Is the optional left shift to apply to the immediate, defaulting to
LSL #0, and can be eitherLSL #0orLSL #12.
