### Summary This PR improves the performance of integration tests by implementing compiled binary caching and optimizing compiler flags. The overall test suite execution time has been reduced by approximately 17% (from ~11.5s to ~9.5s). ### Performance Improvements | Metric | Before | After | Improvement | |--------|--------|-------|-------------| | Full test suite | ~11.5s | ~9.5s | ~17% faster | | Integration tests only | ~10.5s | ~8.3s | ~21% faster | ### Changes #### 1. Compiled Binary Caching Added a caching mechanism to avoid unnecessary recompilation of the same parsers: - Introduced `IntegrationHelper.compiled_parsers` hash to track compiled binaries - Cache key includes both parser name and lrama command arguments - Only recompiles when the parser hasn't been built or the binary doesn't exist - Particularly effective for parsers used multiple times: - `after_shift`: used 2 times - `destructors`: used 4 times #### 2. Optimized Compiler Flags Changed GCC compilation flags to prioritize compilation speed over runtime performance: - Changed from `-ggdb3` to `-g` (minimal debug info) - Added `-O0` flag (no optimization) - These changes are appropriate for integration tests since we only care about correctness, not runtime performance #### 3. Memory Cleanup Added `after(:all)` hook to clear the compiled parsers cache, preventing memory bloat during test runs.
