Method Detail

moveSPAndEmitStore

public static int moveSPAndEmitStore(AArch64MacroAssembler masm,
                                     Register input,
                                     Function<Register,Integer> storeGen)

This helper method moves sp to a scratch gp register before generating the store code. This is needed because store instructions cannot directly refer to the sp register. This is because both ZR and SP are encoded as '31'.
