Occurrence analysis plug-in
The Occurrence analysis plug-in shows the uses of a
variable in a C program. This analysis highlights the left-values
that may access the selected variable.
As shown by the example, the analysis takes aliases into account.
It is available through a contextual menu at each variable in the Frama-C graphical user interface. Invoking this analysis on a variable displays the occurrences of this variable in the program:
The plug-in can be used both with the graphical user interface and in batch mode. In batch mode, the command is:
frama-c -occurrence file1.c file2.c
This prints on standard output all occurrences of each variable.
This plug-in depends on results of the Value analysis plug-in.
