* Grammar updates
- Make class parameters required
* Add ClassLink; wip with `super()` calls in ctors
* More AST nodes as ScopableNames
- (function call) Argument
- FunctionParameterDeclaration
* Add support for ambiguity handling
* Add few more tests
* Handle returns in constructors
- Semantic analysis to error on returning a value
- Introduce specific emitter method for returning from constructor
- Various tests
* Refactor super building to pre-semantic analysis
* Adding several tests, some are TODO
- found an issue with function resolver and funcrefs, fix later
* Address self-review comments
* Fix funcref global func references, tests
* POLLOG* macros use the new formatting
removed all old logging functions
* removed old fmt lib from everything except StreamWriter
removed unneeded functions
* fixed review comments
Adds:
- ast/Argument: AST node for an argument passed to a function.
- ast/FunctionCall: AST node for a function call.
- codegen/ModuleDeclarationRegistrar: The code generator registers module function declarations with this in order to determine module indexes and function indexes for instructions.
- model/FunctionLink: this is a reference either:
- from: a FunctionCall or a FunctionReference
- to: a ModuleFunctionDeclaration or a UserFunction
- optimizer/ReferencedFunctionGatherer: a visitor that determines which module functions and user functions are referenced, by looking at function calls and function references.
Also:
- CodeGenerator registers module functions
- InstructionGenerator generates code for function calls
- InstructionEmitter generates TOK_FUNC instructions
- StoredTokenDecoder decodes TOK_FUNC instructions
After all of this, the compiler can compile print("hello, world");
