- Fixed me ValueId inconsistency in static box methods
- Previously, each me reference generated a new const __me__ ValueId
- Now caches the first me ValueId in variable_map for reuse
- This ensures RefSet and RefGet operate on the same object
- ArrayBox get/set/push now working correctly in VM mode
- Test results: 1, 42, 3 (as expected)
🔧 Technical Details:
- build_me_expression() now stores fallback ValueId in variable_map
- Subsequent me references reuse the same ValueId
- VM BoxCall debug logs confirm ArrayBox methods dispatch correctly

- Eliminate static_mut_refs warnings by using once_cell::sync::Lazy
- Make FileMode enum public to fix private_interfaces warning
- Reduce warnings from 6 to 3
- Prepare for Rust 2024 edition compatibility
- Fix NyashParser import path in vm.rs tests
- Improve BoxCall fallback logic for plugin/builtin methods
- Add proper function existence checks before lowering to Call
This ensures plugin Box methods correctly fall back to BoxCall
when the corresponding user-defined function doesn't exist.

Fixed infinite loop issue in VM by addressing phi node caching problem.
The phi node was caching the initial value and returning it for all
subsequent iterations, preventing loop variable updates.
Changes:
- Created vm_phi.rs module to separate loop execution logic (similar to mir/loop_builder.rs)
- Disabled phi node caching to ensure correct value selection each iteration
- Added LoopExecutor to track block transitions and handle phi nodes properly
- Fixed VM to correctly track previous_block for phi input selection
The VM now correctly executes SSA-form loops with proper variable updates:
- Loop counter increments correctly
- Phi nodes select the right input based on control flow
- Test case now completes successfully (i=1,2,3,4)

- Added Store instruction generation in build_assignment()
- This partially addresses the VM infinite loop issue
- However, the loop still uses old values (%0) instead of updated values
- Need to implement proper SSA phi nodes for loop variables
The root cause: MIR generation doesn't properly track variable updates
in loops. Current SSA implementation lacks phi nodes.

- Fix MIR builder to handle built-in Box types (IntegerBox, StringBox, etc.) specially
- Generate MIR with actual constant values instead of ref_new instructions
- Enhance LLVM mock compiler with MIR interpreter foundation
- Add value storage HashMap for future MIR instruction interpretation
This enables proper MIR generation where 'new IntegerBox(42)' becomes '%0 = const 42'
instead of '%0 = ref_new "IntegerBox"'. This is essential for future LLVM code generation.
Example MIR improvement:
Before:
%1 = const "IntegerBox"
%0 = ref_new %1
After:
%0 = const 42

Phase 5.3 of MIR 35→26 reduction project:
- Replace RefNew with NewBox in MIR builder
- Remove unnecessary Const generation for box types
- Process arguments properly for NewBox instruction
- StringBox special handling maintained with NewBox
Frontend now generates only 26-instruction set compliant MIR.
Build successful with expected deprecation warnings.
Phase 5.2 of MIR 35→26 reduction project:
- VM backend: Reject all 17 deprecated instructions with proper error messages
- WASM backend: Reject deprecated instructions with migration guidance
- All deprecated instructions now properly handled in both backends
- Build successful with expected deprecation warnings
Deprecated instructions removed:
- UnaryOp → Use BinOp
- Load/Store → Use BoxFieldLoad/BoxFieldStore
- ArrayGet/ArraySet → Use BoxFieldLoad/BoxFieldStore or intrinsics
- Print/Debug → Use Call @print/@debug
- TypeCheck/Cast → Use Call @type_check/@cast
- Throw/Catch → Use Call @throw/@catch
- RefNew → References handled implicitly
- BarrierRead/BarrierWrite → Use AtomicFence
- FutureNew/FutureSet/Await → Use NewBox/BoxCall
- Copy/Nop → Not needed in final IR
Phase 4-3c-3 Complete: WASM host functions now correctly output string content
## Changes:
- Fixed MIR builder to handle StringBox with string literal arguments
- Special case for to generate proper string constants
- Removed debug output after successful verification
- WASM now correctly outputs "Hello MIR!" instead of "StringBox"
## Test Results:
- MIR generation: ✅ Generates correctly
- WASM compilation: ✅ String data correctly placed at offset 4096
- WASM execution: ✅ Outputs "Hello MIR\!" as expected
## Technical Details:
- Modified build_new_expression() to detect StringBox with literal arguments
- Generates Const instruction with actual string content
- Host function reads StringBox memory layout correctly
This completes the WASM string output functionality for Phase 4.
