Program code is statically analyzed (without actually executing the code) by "virtually" executing the code with a virtual processor or emulator that steps through the code. The analysis includes locating entry and exit points, identifying branch points, analyzing one or more code paths from a branch, noting calls to external functions (e.g., libraries), etc. Programming logic errors can be located, such as calls that never return or isolated code that can never be reached. Analysis can include dynamic analysis of code when emulation is combined with a debugger, for example.
