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.
Another example may be an 8-bit register with the bit pattern 01010101 and the carry flag set; if we execute a rotate left through carry instruction, the result would be 10101011 with the carry flag cleared because the most significant bit (bit 7) was rotated into the carry while the carry was rotated into the least significant bit (bit 0).
Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
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. [5]
x86 assembly language has two primary syntax branches: Intel syntax and AT&T syntax. [6] Intel syntax is dominant in the DOS and Windows environments, while AT&T syntax is dominant in Unix-like systems, as Unix was originally developed at AT&T Bell Labs. [7] Below is a summary of the main differences between Intel syntax and AT&T syntax:
Add the operand to the accumulator, A. Opcode 0x23 (RL A, "rotate left" but actually a shift left) may be thought of as ADD A, A. 3y: ADDC A, operand Add the operand, plus the C bit, to the accumulator. Opcode 0x33 (RLC A, rotate left through carry) may be thought of as ADDC A, A. 4y: ORL A, operand Logical OR the operand into the accumulator.
It supports Intel-style assembly language on the IA-32 and x86-64 computer architectures. It claims high speed, size optimizations, operating system (OS) portability, and macro abilities. [2] [3] It is a low-level assembler [3] and intentionally uses very few command-line options. It is free and open-source software.
In the x86 assembly language, the JMP instruction performs an unconditional jump. Such an instruction transfers the flow of execution by changing the program counter.There are a number of different opcodes that perform a jump; depending on whether the processor is in real mode or protected mode, and an override instruction is used, the instructions may take 16-bit, 32-bit, or segment:offset ...
