Also: OG compiler debug info for foreach iterator changed to match actual variable name
Adds:
- ast/DebugStatementMarker: for "intrusive debug" (ecompile -i) instructions
- codegen/DebugBlockGuard: pushes and pops debug block #
- format/DebugStoreSerializer: writes .dbg and .dbg.txt files
- representation/DebugBlock: holds parent block # and local variable names for each block
- representation/DebugStore: holds all debug information
Adds:
- ast/UserFunction AST node for user-defined functions.
- astbuilder/AvailableUserFunction: reference to a parse tree for a user function.
- The AST builder only generates ASTs for user functions that are actually referenced.
- astbuilder/UserFunctionVisitor: visits (builds an AST for) a parse tree for a user function.
- This happens after the .src or .inc file has been otherwise processed, so this class serves to hook up the correct SourceFileIdentifier to the AST.
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");
* Add codegen/InstructionEmitter
* Add codegen/InstructionGenerator
* CodeGenerator: emit progend
Checkpoint: compiler can compile an empty file
* Comment reason for having both emit and emitter.
