2020-04-09[posix-runtime] Improve model to handle full-path symbolic filesTimotej Kapus
2020-04-09[posix-runtime] Add test for full path consistency for symbolic filesTimotej Kapus
2020-04-08readStringAtAddress: support pointer into objectsMarek Chalupa
The code assumed that the passed pointer points at the beginning of the object. Remove this assumption and support any (constant) pointer. The string is read util either the end of the object is hit (in which case a warning is issued as the string was not zero terminated) or until the terminating zero is found.
2020-04-08test: add a new test for readStringAtAddressMarek Chalupa
Read strings from different parts of objects.
2020-04-08readStringAtAddress: use stringstream to obtain the stringMarek Chalupa
The code is simpler and more in the spirit of C++.

2020-03-01[klee-stats] Grafana: Limit number of entries to query for column namesMartin Nowack
2020-03-01[klee-stats] Use the last row inserted instead of the row with highest ↵Martin Nowack
Instructions Last `Instructions` is not a good identifier to retrieve the correct row. For the default setup, KLEE will generate two entries with the same last instruction. One before clean-up and one after clean-up (i.e. if states are terminated on halt). Using `rowid` will select the last line.
2020-03-01[klee-stats] Refactor preparing and printing the tableMartin Nowack
The number and order of statistics in klee-stats is hard coded. Moreover, adding new statistics to KLEE lead to crashes. Rewriting that part of the script generalises and streamlines the process. List of changes: * Extend legend: this is used for known columns to provide shorter names * simplify sqlite handling and make it more robust and reading of data * select columns based on internal KLEE names * streamline addition of artificial columns and make it robust * handle the case if different runs should be compared but not all have the same statistics * fix calculation of summary row: - avg of column if column is showing a relative value or avg value - max of column if column is showing a max value - sum of column entries, else
2020-03-01[klee-stats] Check for existence of stats file for Grafana as wellMartin Nowack

2020-02-19Use `ref<>` for MemoryObject handlingMartin Nowack
This uses the `ref<>`-based memory handling of MemoryObjects. This makes it explicit that references are held in: - ExecutionState::symbolics - ObjectState
2020-02-19Use `ref<>` for UpdateNodeMartin Nowack
Remove additional reference counting as part of UpdateNodeList and UpdateNode. Simplifies code.
2020-02-19Clean-up header filesMartin Nowack
* Replace c header with c++ header * remove unneeded header file
2020-02-19Add move assignment operator and move construct for `ref` class.Martin Nowack
2020-02-19Add `ReferenceCounter` struct utilized by ref<>Martin Nowack
Using KLEE's `ref<>` shared ptr requires the referenced object to contain a reference counter to be added and initialised to 0 as part of the constructor. To support better reuse of the `ref<>` ptr add a `ReferenceCounter` struct. Just adding this struct to a new class/struct as member enables reference counting with `ref<>` - no additional counter management needed.
