RRX Rotate Right with Extend Rotate Right with Extend provides the value of the contents of a register shifted right by one place, with the Carry flag shifted into bit[31]. MOV, MOVS (register) It has encodings from the following instruction sets: A32 ( A1 ) and T32 ( T3 ) . != 1111 0 0 0 1 1 0 1 0 (0) (0) (0) (0) 0 0 0 0 0 1 1 0 RRX{<c>}{<q>} {<Rd>,} <Rm> MOV{<c>}{<q>} <Rd>, <Rm>, RRX Unconditionally 1 1 1 0 1 0 1 0 0 1 0 0 1 1 1 1 (0) 0 0 0 0 0 1 1 RRX{<c>}{<q>} {<Rd>,} <Rm> MOV{<c>}{<q>} <Rd>, <Rm>, RRX Unconditionally <c> See Standard assembler syntax fields. <q> See Standard assembler syntax fields. <Rd> For encoding A1: is the general-purpose destination register, encoded in the "Rd" field. Arm deprecates using the PC as the destination register, but if the PC is used, the instruction is a branch to the address calculated by the operation. This is an interworking branch, see Pseudocode description of operations on the AArch32 general-purpose registers and the PC. <Rd> For encoding T3: is the general-purpose destination register, encoded in the "Rd" field. <Rm> For encoding A1: is the general-purpose source register, encoded in the "Rm" field. The PC can be used, but this is deprecated. <Rm> For encoding T3: is the general-purpose source register, encoded in the "Rm" field.
