compile-analysis

To measure single-file compile time, the skill extracts real compile commands and executes an isolated build run in the out/{product} directory, capturing elapsed time and peak memory metrics for the specific OpenHarmony ACE Engine .cpp file.

Header include dependency visualization works by parsing generated .ii preprocessed files using the built-in parse_ii.py script, producing a hierarchical dependency tree that maps which headers drive the compilation cost for the analyzed file.

To find compilation bottlenecks in a specific .cpp file, the skill measures real compile time and peak memory from an isolated build run and visualizes deep or broad header include chains that cause slow builds or recompilation costs.

Yes, you can use standalone benchmark scripts to validate build optimization results. The skill generates reusable enhanced compile scripts that you can re-run multiple times for accurate before and after performance comparisons.

Yes, you need a specific OpenHarmony product configuration. The skill executes enhanced compilation directly in the out/{product} directory, requiring you to specify a target product such as rk3568 when analyzing ACE Engine compilation efficiency.
