Rotate instructions in arm

Rotate With Carry Instructions Like with shifts, the rotate can use the carry bit as the "extra" bit that it shifts through. Rotate dest to the right by src fileslib. Re: ARM Assembly Rotate instruction Multiply or divide (especially by 2). Rotate a particular bit into the sign bit for a fast branch if bit • The Shift and Rotate instructions include: SHL - Shift Left. ROL – Rotate Left. SHR - Shift Right. ROR – Rotate Right. SAL – Shift Arithmetic Left. RCL - Rotate Carry Left. SAR – Shift Arithmetic Right. RCR - Rotate Carry Right.

What does LSR and LSL do? LSL provides the value of a register multiplied by a power of two. LSR provides the unsigned value of a register divided by a variable power of two . Both instructions insert zeros into the vacated bit positions. ROR provides the value of the contents of a register rotated by a value.
