* Add -Z option to print string tree
* Simple test to print an AST
* Make CompiledScript owner of the tree
* some refactoring
- rename ecompile.cfg option
- rename AST generator class
* core-changes, docs
* fix warnings
* Make ClassDeclaration only track class methods
* Keep methods, constructors in compiler workspace
- Fix UserFunctionBuilder to force reference to methods, constructors
- Fix Optimizer to include methods, constructors in referenced functions
* WIP for ClassDeclarationRegistrar
- Stub implementation of ClassDeclaration and its Registration
- Create "function table entry" via debug statements
* Use function links in methods
* Finish up ClassDescriptor
- Introduce MethodDescriptor for encapsulation
- ClassDeclarationRegistrar can register and take descriptors
* Handle read and write class table in eprog
* Pass Report to code generator for debug statements
* Fix implementation
- It _is_ possible for the constructor to be empty, ie. static classes
* Update DebugStoreSerializer
Print class table to dbg txt file
* Add missing method_names insertion
* Address GitHub CI Annotations
- unused variable 'uf'
- '=': conversion from 'size_t' to 'unsigned int'
* Introduce FunctionReferenceRegistrar
- Track function references created by functors
- Remove ValueStack-held attributes for functors
- Add Function References section to escript program
- Use Function References section in ins_functor
- Update escript version
* Update listfile snapshots
- Remove ValueStack-held attributes created by functors
* Add function reference tracking to function references
- `emit.function_reference` uses funcref registrar + emits that index
- `ins_funcref` uses parameter count + is variadic from prog funcref table
- update listfile snapshots
* Add core-changes
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.
