WebISA be an Instruction Set Architecture (ISA), and L IR be an Intermediate Representation (IR). We use a superscript to specify the name of an ISA or an IR. For example, Lx86 ISA means x86 assembly language, and L VEX IR is VEX IR. An instance of an IR is a sequence of statements deﬁned in the semantics of the IR. We also call each statement shang chi rating common sense media

This makes it natural to have groups of 3 bits in the encoding for other instructions, too. – Peter Cordes shang chi premiere spoilers

"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. " - Binary representation of intel x86 isa
