R16 - ruby to dcpu16 assembler

Basically a bunch of helper methods to generate dcpu16 code.

Here is the notch example (http://0x10c.com/doc/dcpu-16.txt):

R16::Assembler.code do
  set :a, 0x30
  set [0x1000], 0x20
  sub :a, [0x1000]
  ifn :a, 0x10
  set :pc, :crash

  set :i, 10
  set :a, 0x2000
  set_label :loop
  set [0x2000, :i], [:a]
  sub :i, 1
  ifn :i, 0
  set :pc, :loop

  set :x, 0x4
  jsr :test_sub
  set :pc, :crash

  set_label :test_sub
  shl :x, 4
  set :pc, pop

  set_label :crash
  set :pc, :crash
end

Of course you can use full power of ruby. Currently there are basic functions calls (see ABI [1]), scoped labels and some basic control structure elements (while, do-while, if, ...).

A more sophisticated example:
