- Introduced SSmalltalkScanner for token scanning and parsing. - Created SToken and its derived classes for token representation. - Implemented Stream class for handling source code streams. - Developed SCompiler for frontend compilation logic and character classification. - Added SSmalltalkCompiler to orchestrate the compilation pipeline. - Implemented Stretch class to represent source code ranges. - Introduced egg::string for Unicode string handling in the compiler. - Added error handling and semantic analysis capabilities.
- Introduced SMessageNode to represent message send nodes in the AST. - Implemented SMethodNode for method definitions, including method building and literal extraction. - Created SNumberNode and SStringNode for number and string literals, respectively. - Added SReturnNode for handling return statements in methods. - Developed SPragmaNode to manage pragmas, including primitive and FFI pragmas. - Established SSelectorNode for message selectors, supporting binary and keyword selectors. - Enhanced SParseNode and SScriptNode as base classes for AST nodes, providing common functionality. - Introduced SParseNodeVisitor interface for traversing the AST. - Implemented LiteralValue struct to represent various literal types in Smalltalk.
…ocessing - Introduced TonelReader.h for parsing Tonel-format .st files into ClassSpec. - Added CompilerTypes.h to define AST node and binding type identifiers. - Implemented MessageInliner for control-flow optimization in Message nodes. - Created SemanticVisitor for analyzing and transforming the AST, integrating MessageInliner. - Developed TreecodeEncoder to convert AST nodes into Egg treecode format. - Added necessary methods and structures to support encoding and inlining functionalities.
… scanning Separate module-loading responsibilities from bootstrapping: - Extract Loader class (Loader.h/cpp) to handle module resolution and loading from both .ems files and source directories - Move Bootstrapper to Bootstrap/ subdirectory, now focused solely on kernel bootstrapping from source - Delete old monolithic Bootstrapper.h from runtime/cpp root Introduce SymbolProvider abstraction (SymbolProvider.h/cpp): - BootstrapSymbolProvider: used during kernel bootstrap - DynamicSymbolProvider: uses the live symbol table at runtime - Runtime::switchToDynamicSymbolProvider_() for the transition - Remove inline symbolTableAt_() and knownSymbols map from Runtime Refactor GC root scanning in G1GC: - Extract resolveObject_() helper to deduplicate evacuation/marking logic shared between scanBehavior() and scanSlot() - Add scanRoot_(Object**) virtual method for properly scanning root pointers (stack frames, GCedRefs) instead of casting them to fake HeapObjects and using scan_from_to_ Other changes: - Add _error: undermessage and DictionaryNew primitive - Guard primitiveNewBytes/primitiveNewSized against non-SmallInteger args - Add Runtime::send_to_, send_to_with_ convenience methods - Refactor Launcher to bootstrap from source via Loader and use message sends to load/run modules - Remove dead code and debug leftovers from Runtime lookup cache - Fix unused variable in SSemanticVisitor>>visitAssignment:
Consolidate the string utility class under the Egg namespace to match the project convention. Move egg_string.h from Compiler/ to Utils/ and update all includes accordingly. Also update copyright years to 2025-2026 across affected files.
Extract ImageSegment as a lightweight base class providing only the common interface (header, memory bounds, exports, dumpObjects) used by Runtime. Move file-loading logic (load, fixPointerSlots, import resolution) into a new FileImageSegment subclass. BootstrappedKernel now extends ImageSegment directly, eliminating the null-stream constructor hack and dummy header workaround.
- primitiveAt: use failPrimitive instead of error() for type/bounds checks, including bounds check for bytes objects - primitiveSMIBitShift: detect overflow and fail the primitive - primitiveSMIIntDiv/IntQuot: implement floored division/modulo semantics to match Smalltalk // and \\ - underprimitiveBitShiftLeft/SMIBitShiftLeft: detect overflow and return nil instead of silently wrapping - Use existingSymbolFrom_ for doesNotUnderstand: lookup - Remove stale debug comments
