The import tool does support the following import strategies: - BasicImporter: generates def-use equivalence classes for read and write memory accesses - DCiAOKernelImporter: generates equivalence classes for read access in the ciao kernel space. Change-Id: I8960561d3e14dcf5dffa3ff7a59b61a5e8f7e719

/** \class DCiAOKernelImporter
|

*
|
|
* Strategy for importing traces into the MySQL Database, that cover
|
|
* only kernel space data address. A single trace is only added to the
|
|
* database, if it has the following form:
|
|
*
|
|
* - The memory access is after the kernel has passed the
|
|
* getEnterKernelAddress(), before it passes the
|
|
* getLeaveKernelAddress() again. Short: if the programm is in
|
|
* kernel space.
|
|
* - Only memory addresses that are located in the os::data::dynamic
|
|
* namespace
|
|
* - Only memory accesses to addresses that were not written in the
|
|
* current kernel space phase.
