π-WAM Assembly: Comfortable Labels and Goto (Re: π-WAM Contest: 1 Million Packets with Prolog)

Show all headers | View raw

Hi,

What Hamelt is to English language, is Hack to
Compiler Construction. The playbook of Hack contains
every drama that a Compiler Construction will face.
In the following we show how we realized Project 6:
Assembler from the Nand to Tetris journey via
a little Prolog DSL.

Our initial quick and dirty prototype deploys
double buffering to determine code lengths and
is brittle in examples such as between/3. Our
assembly DSL does without symbol tables but with
Prolog logical variables only. We could fix the
between/3 glitch and give a first disjunction
(;)/2 prototype.

Bye
