    Description

      PrintAssembly and PrintOptoAssembly output has, over time, accumulated some "optical inconsistency". It is the intention of this enhancement to harmonize output across platforms.

      When PrintAssembly is requested, but no disassembler library is available, the current fallback is to turn on PrintOptoAssembly. While being better than nothing, it can't provide the detailed insight of real assembly code. This enhancement implements a "raw hex dump" option as fallback. An external tool can then be used to create mnemonic assembler code from the hex data.
