# Wilson is a pure ruby x86 assembler. No, really. Worst Idea Evar.
# Forked from: https://github.com/seattlerb/wilson/
#
# Refactored by @ollpu to run on modern Ruby, x86-64 (Linux only).
#
# Why "wilson"? I wanted to name it "metal", but there is an existing
# project with that name... So I'm naming it after Wilson Bilkovich, who
# is about as metal as you can get (and it is easier to spell than
# "bilkovich", even tho that sounds more metal).
#
# Wilson is a port (and extension) of the smalltalk x86 assembler by
# Michael Lucas-Smith. I came across it when he presented it at
# Smalltalk SuperPowers at OOPSLA 2008.

  # MachineCodeX86 is a concrete implementation of a machine to create
  # X86 assembly code on.
  #
  # You can use this class in two ways:
  #
  # a) you can instantiate an instance and use its register variables
  #    to build up machine code in the @stream variable and then use
  #    those bytes in any way that you see fit, or
  #
  # b) you can make a subclass of this class much like you do with
  #    ExternalInterface and put methods on the class that will
  #    compile in to assembler code that can be called from Smalltalk
  #    code
  #
  # == Using MachineCodeX86 for scripting
  #
  # This is the long hand way of writing assembly code, since you
  # always include a receiver with every command.
  #
  #     asm = Assembler.MachineCodeX86.new
  #
  # Once you have an assembler, you can access the registers and send
  # commands to them, eg:
  #
  #     asm.eax.mov 1
  #
  # As you send the commands, the @stream will build up containing the
  # X86 assembler bytes you can use. You can use memory addresses in
  # your assembler code with the #m method, eg:
  #
  #     asm.eax.m.mov 1
  #
  # Once you are finished, you simply send:
  #
  #     asm.stream
  #
  # This will return you the stream of bytes.
  #
  # == Labels & Jumps
  #
  # You can do labels and jump to them using two different label
  # commands. The first is #label, which places a label jump point
  # immediately on call, eg:
  #
  #         label = asm.label
  #         label.jmp
  #
  # The other is a future label that can be placed at some future
  # point in the program and jumped too
  #
  #         label = asm.future_label
  #         asm.eax.xor asm.eax
  #         label.jmp
  #         asm.eax.inc
  #         label.plant
  #
  # You #plant the future label where you want it to actually be and
  # past references to it will be updated. Future labels will always
  # use a dword jmp so that there's space to fill in the command if
  # the jmp ends up being far.
