In Arm Assembly, there are multiple commands to shift bits such as Logical Shift Left $($LSL$),$ Logical Shift Right $($LSR$),$ Arithmetic Shift Right $($ASR$),$ Rotate Right $($ROR$),$ etc. I understand that these can be used to shift the value in Rm for a maximum of $31$ bits, replacing shifted bits with $0$s$.$ But, what I am still struggling to understand is in what scenario to use each of these different operations. For example, do we only use LSL$/$LSR when we was to do bit multiplication?
