In a binary search tree, a right rotation is the movement of a node, X, down to the right.This rotation assumes that X has a left child (or subtree). X's left child, R, becomes X's parent node and R's right child becomes X's new left child.
Rotate right by immediate without affecting flags. SARX ra,r/m,rb: VEX.LZ.F3.0F38 F7 /r: Arithmetic shift right without updating flags. For SARX, SHRX and SHLX, the shift-amount specified in rb is masked to 5 bits for 32-bit operand size and 6 bits for 64-bit operand size. SHRX ra,r/m,rb: VEX.LZ.F2.0F38 F7 /r: Logical shift right without ...
In assembly languages these instructions are represented by mnemonics such as ADD/SUB, ADC/SBC (ADD/SUB including carry), SHL/SHR , ROL/ROR (bit rotates), RCR/RCL (rotate through carry), and so on. [2] The use of the carry flag in this manner enables multi-word add, subtract, shift, and rotate operations.
In addition to the PIC18's four rotate instructions, the H08A has ARLC (identical to RLCF, but also sets the overflow flag if the sign bit changes) and ARRC, which is an arithmetic right shift, preserving the msbit of the source.
In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits.It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.
The formal definition of an arithmetic shift, from Federal Standard 1037C is that it is: . A shift, applied to the representation of a number in a fixed radix numeration system and in a fixed-point representation system, and in which only the characters representing the fixed-point part of the number are moved.

In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions.
