426462 - Major rewrite of abstract syntax trees

Status: RESOLVED FIXED

(Tamarin Graveyard :: Self-hosting compiler (ESC), defect)

Description

[Lars T Hansen]

Attachment: Big patch

This patch converts the ASTs to be based mainly on classes and interfaces (plus arrays and primitive data).

The new classes are self-serializing and deserializing, with the help of a little glue code, so ast-encode.es and ast-decode.es disappear completely.

AST tag types that were defined as classes and recognized by 'switch type' in the code generator have been recast as numeric values (aids serialization, probably aids performance eventually).

Big patch

I miss the union types already, but I'll take one for the team ;) This will speed things up a bit and provide better (shape) checking.
