The code generator / pass takes a subset of the L0 language as input and translates it to asm.js. This is a very early implementation, based on `pass0`, with lots of issues and missing features.
It just writes the asm.js code to a file and invokes Node.js on it.

The code generator takes a subset of the
L0language as input and translates itto
asm.js. It's currently more a proof-of-concept, based onpass0, but itlargely works already, in that it produces valid
asm.jscode for most of theL0subset it supports.Compared to
L0, the subset:CheckedCall,Raise,Except, etc.)Choiceor float-valueSelectsupportA grammar for the new intermediate language is missing, as well as a pass to
lower
L0into said language.For the sake of simplicity, the code generator currently formats the final code
in-place, but first emitting a
PackedTreethat is then turned into text would becleaner (and possibly more efficient).
