I am currently implementing the shift operations for our backend and noticed that there are no shift right/left with carry in the LLVM Language Reference Manual. Is this because it is safe to assume that the shift with carry instructions are only carried out when a shift instruction is expanded? If that is not the case, are there other reasons why there is no IR instruction equivalent for shift with carry instructions?
Thank you in advance for your help!
