5. Running GNAT SAS Again
As you may have noticed already, GNAT SAS recorded the results of the first run that you made as the baseline for successive runs after possible code modifications, as shown by the top line displayed in the GNAT SAS report:
Base run: sdc.baseline.sam Current run: sdc.sam
Notice the different kinds of filters which are available on the right side of the window, in panel Message ranking, in particular the Message history part: selecting these different filters will show/hide the corresponding messages in the Locations View at the bottom. By default, only the messages which correspond to the current run (either added or unchanged) are shown.
Uncheck the unchanged box in Message history. This clears the location view from all previously reported messages.
Now check the removed box: if –show age+removed is used, you will see all the messages which have disappeared since the base run (the first run in this case).
GNAT SAS defines two types of runs: regular and baseline. The runs are represented by sam files. A first GNAT SAS run is a baseline run and it results in a sam file <PROJECT_NAME>.baseline.sam. All the subsequent runs are regular runs resulting in sam file <PROJECT_NAME>.sam and are compared to the baseline run.
In order to bump a baseline to a current run, you can use the menu . You can also set a baseline to a given run via .
