Phase 5 (Runtime) Test Execution for Mojo Compiler
|
|
===================================================
|
|
|
|
This comprehensive test runner executes Phase 5 (Runtime) tests for the Mojo compiler
|
|
using the snake.mojo program. It verifies:
|
|
|
|
1. FFI Binding & Linking
|
|
- SDL3 library FFI symbols resolved
|
|
- Function pointers correctly linked
|
|
- Symbol table populated
|
|
|
|
2. Memory Management
|
|
- Heap initialization (1MB default)
|
|
- Allocation tracking
|
|
- Peak memory measurement
|
|
- Memory utilization
|
|
|
|
3. Full Execution
|
|
- Phases 1-4 compilation pipeline
|
|
- Runtime linking and initialization
|
|
- Program execution with timeout
|
|
- Exit code verification
|
|
|
|
Reports:
|
|
- FFI symbols linked count
|
|
- Memory allocation details
|
|
- Execution timing and status
|
|
- Exit codes and results
