288f01a0c2 GCC fixes for zcc_compile.(cpp|h) 2016-03-20 11:34:41 -05:00

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.

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

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.
