The super() call resolution is changed from dynamic runtime lookup (walking the receiver's class hierarchy) to static binding at class definition time. This ensures correct method dispatch when a method containing a super call is inherited by another subclass.
Key changes:
- In `callSignature()`, when compiling a `CODE_SUPER_0` instruction, a constant slot is created and filled with NULL, to be populated with the superclass reference when the method is bound.
- In `getNumArguments()`, the `CODE_SUPER_0` through `CODE_SUPER_16` cases are moved after the newly added 2-argument opcodes (`CODE_JUMP`, `CODE_LOOP`, etc.) to maintain correct ordering.
- In `dumpInstruction()`, the debug output now prints the superclass constant index alongside the method symbol.
- In `runInterpreter()`, the super call execution reads the superclass directly from the function's constant table instead of deriving it from the receiver's class at runtime.
The READ_BYTE and READ_SHORT macros are defined locally within functions
in wren_debug.c and wren_vm.c but were not being undefined after use,
causing potential redefinition warnings or errors when these macros
conflict with other definitions in the same translation unit. This
change adds #undef directives at the end of dumpInstruction in
wren_debug.c and runInterpreter in wren_vm.c to properly clean up
the macro definitions.
Remove the `WrenVM* vm` parameter from `wrenValueBufferInit`, `wrenByteBufferInit`,
`wrenIntBufferInit`, `wrenStringBufferInit`, `wrenSymbolTableInit`,
`wrenMethodBufferInit`, `wrenStringFind`, and `wrenDebugPrintStackTrace`
functions across the compiler, core, debug, utils, value, and VM modules.
Update all call sites and macro definitions to match the simplified signatures,
eliminating dead parameters that were never used within the function bodies.
The dumpObject function in wren_debug.c was incorrectly printing "[fn %p]" for
OBJ_RANGE objects instead of the correct "[range %p]" label. This fix ensures
that range objects are properly identified during debug output.
Separate Wren VM library sources from CLI tool sources by moving them into
src/vm/ and src/cli/ subdirectories respectively. Update the Makefile to use
separate wildcard patterns for each directory, generate distinct object file
paths under build/vm/ and build/cli/, and adjust include paths to src/include.
Also update the Xcode project file to reference the new file locations.
