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. pool cartridge outlet leaking

"WebJun 19, 2011 · Hmm, interesting. x86 has 8 registers, and a few opcodes use the low 3 bits to encode a destination register (including inc r32, dec r32, xchg r32, eax, and mov r32, imm32 ). This makes it natural to have groups of 3 bits in the encoding for other instructions, too. – Peter Cordes " - Binary representation of intel x86 isa
