    • The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor. The x86 instruction set has been extended several times, introducing wider registers and datatypes as well as new functionality.

    x86 is a family of complex instruction set computer (CISC) instruction set architectures initially developed by Intel based on the Intel 8086 microprocessor and its 8088 variant. The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit …

    How to learn x86 assembly?

    x86 can be tedious to learn for any number of reasons:

    • no two registers are the same.
    • not all instructions work with all registers.
    • Some branch instructions have a very short range, so you may see branch to branch instructions
    • The number of different address modes can be surprising.

    How many x86 instructions?
    • The number of potential x86-64 instructions is huge, as the hardware limit is the number of bytes that the CPU is willing to fetch for one instruction. On x86-64 this is 15 bytes [3] (pp 208) and as a result there are 215*8 potential instructions. • Certain prefix bytes can be added in advance of the

    How exactly does the x86 loop instruction work?

    To illustrate with examples:

    • You can’t add two immediate constants together, even though you can in C. ...
    • You can add two 32-bit registers in one instruction, but you can’t add three 32-bit registers – you’d need to break it up into two instructions.
    • You can’t add a 16-bit register to a 32-bit register. ...

    The full x86 instruction set is large and complex (Intel's x86 instruction set manuals comprise over 2900 pages), and we do not cover it all in this guide. For example, there is a 16-bit subset of the x86 instruction set. Using the 16-bit programming model can be quite complex.
