After you have analyzed your project using C-STAT and possibly corrected some errors, it can be useful to perform regression testing using the IAR Command Line Build Utility (iarbuild.exe) located in the common\bin directory.

To clean the database from old errors, use a command line like this:

iarbuild.exe MyProject.ewp -cstat_clean Debug

To analyze all files in the project, use a command line like this:

iarbuild.exe MyProject.ewp -cstat_analyze Debug

C-STAT generates output information, for example:

Analyzing configuration: MyProject - Debug

Updating build tree…

Starting C-STAT analysis

Analysis completed. 164 message(s)

Compare the number of messages reported with the number of messages produced in previous builds. If the number has increased, new errors have been introduced as a result of earlier development.

In the IDE, open your project, perform the analysis, and locate the cause of the new message.

Alternatively, you can create an HTML report from the command line, for example like this:

ireport.exe --db cstat.db --project MyProject.ewp --full --output MyProject.html

This creates a report in MyProject.html, see also Generating an analysis report.

Typically, you might want to repeat this process during nightly builds to continuously control that existing code is not affected by new code.
