Phase 5 (Runtime) Test Runner for Mojo Compiler
|
|
================================================
|
|
|
|
This runner executes Phase 5 tests using the Mojo compiler implementation.
|
|
It chains Phases 1-4 and executes Phase 5 runtime operations:
|
|
|
|
1. Load snake.mojo source
|
|
2. Run Phases 1-4 (Frontend, Semantic, IR, Codegen)
|
|
3. Execute Phase 5 (Runtime):
|
|
- FFI binding for SDL3
|
|
- Memory allocation and initialization
|
|
- Execution with timeout
|
|
4. Capture and report results
|
|
|
|
Reports:
|
|
- FFI symbols linked
|
|
- Memory allocated
|
|
- Execution status
|
|
- Exit code
