NAME
Asm::X86 - List of instructions and registers of Intel x86-compatible processors, validating and converting instructions and memory references.
VERSION
Version 0.20
DESCRIPTION
This module provides the user with the ability to check whether a given string represents an x86 processor register or instruction. It also provides lists of registers and instructions and allows to check if a given expression is a valid addressing mode. Other subrotuines include converting between AT&T and Intel syntaxes.
SYNOPSIS
use Asm::X86 qw(@instr is_instr);
print "YES" if is_instr ("MOV");
