Code Metrics

Description and example of code metrics

When Polyspace® Bug Finder™ analyzes your code, you can choose to calculate statistics about your program. Use the Calculate code metrics (-code-metrics) analysis option to activate code metric checking. To understand the different code metric results and how Bug Finder calculates them, see these reference pages.

Polyspace Bug Finder does not support calculating stack use metrics. To calculate stack use metrics, use Polyspace Code Prover™. See Calculate stack usage (-stack-usage) (Polyspace Code Prover).
