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 WebComputer Architecture 11 Confusing Instruction Syntaxes Intel syntax for x86 instructions: op dest, src1, src2 ATT syntax for x86 instructions: op src1, src2, dest MIPS syntax for MIPS instructions: – mostly op dest, src1, src2 – But for store, it is “sw src, dest” ARM syntax for ARM instructions: op register, src or dest – Whether the second operand is src …

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 pootis police
