d139ee9f68 - give the 'default' block its own node type in the AST. 
- group a class's body the same way as the global AST. Only partially implemented so far so that constants can be processed.

82ac2081b6 - create struct types. 
- fixed class creation. There was an infinite loop and some missing checks for native classes.
- do not write the compiler's symbols to the same symbol table as the output. The output must go to GlobalSymbols but the internal symbols must go to a namespace specific table that can be discarded after compilation.

b71e8d09ed - create class types from the AST. 
This is the first thing the compiler has to do to get access to the class's symbol table. Of course at this point the final size of a class is not known yet so these are currently all treated as tentative.

aaae9f2e05 Store known but uncompiled nodes in the symbol table 
- Don't bother keeping track of uncompiled nodes in a special table. Use
  the regular symbol table instead. This should in the future make
  compiling nodes referenced deeper than (and before) their definitions
  fairly straightforward.
- Also, break up the compiler's Message() function into Warn() and Error()
  and get rid of zcc_errors.h. I can't really see having a set of error
  numbers being useful.

b66de4116d Remove IsUnary() and IsBinary() 
- This information is already stored in the node's NodeType field, so
  there's no reason to go do a table lookup for it elsewhere. Must have
  been a brain fart when I wrote them in the first place.

16fc9be411 Interpret function calls to type refs as type casts 2013-10-30 20:53:02 -05:00

39d7fa0605 Allow access to the numeric properties. 
- Identifiers can now evaluate to type references.
- The dot operator can now find symbols in type references.

03c4244fd8 Accept only one identifier for class names. 2013-10-29 22:05:09 -05:00

6384613487 Allow using constants in other constants before their definitions. 
- Something like this is now valid:
    const foo = bar + 10;
    const bar = 1000;

76d2e8cfc4 Set node type when nil-ing an id node. 
- Nodes can't stay as type AST_ExprID if they don't also have the
  operation PEX_ID.

850055a766 Add evaluation of constant unary and binary expressions 
- Added ZCCCompiler class as a place to generate IR and symbols from an
  AST. Right now, all it does is simplify constant expressions into
  constant values.
- Do type promotion on the AST where appropriate.
- Added true and false tokens to the parser driver.
