# 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.
