Parsing Architecture 1.0
§We had concern over
scalability of AST
4Settled on a
callback-based architecture
4Clients created only
the data that they needed
§Client would pass in a
requestor to the parser and the parser would pass in parse info as
the parse progressed
4Despite the names, the
IAST* parse info does not form a proper AST
§Client would also be
responsible for passing in ScannerInfo
4Compiler command line
arguments that affect parsing
•Include paths, macro
defs
4Needed to properly
parse
