2020-04-30Move header files from lib/Expr to include/klee/Expr to eliminate includes ↵Cristian Cadar

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.
2020-04-08readStringAtAddress: use stringstream to obtain the stringMarek Chalupa
The code is simpler and more in the spirit of C++.
2020-03-22StatsTracker: remove NumObjects, fix assignment of and always write ↵Frank Busse
ArrayHashTime * fix binding order for assignments when KLEE_ARRAY_DEBUG enabled * always write ArrayHashTime column to run.stats, assign -1 when KLEE_ARRAY_DEBUG disabled * remove unused NumObjects column from run.stats * remove NumObjects panel from Grafana

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.
2020-02-19Add `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.
2020-01-19Remove statistics limit from istats.Martin Nowack
Statistics encoded in `run.istats` were limited to a maximum number of 13 due to encoding in a `uint64_t` variable. This approach has multiple limitations: - a maximum number of 13 statistics were allowed - a subtle bug can be triggered if many more statistics are added - independent of the selected statistics for `run.istats` Depending on the linking order, statistics will get a different ID. Previously, the ID was used to shift a `1` to its position marking the statistic as being used. This will lead to undefined behaviour if more than 63 statistics are used. Using an llvm::SmallBitVector instead fixes both problems.
2020-01-13Assume assembly.ll is local to the run.istats fileMartin Nowack
Assuming a `klee-out-*` directory is moved to a different path location, subsequent analysis of the run.istats with KCachegrind focusing on assembly is impossible as the `assembly.ll` cannot be found. The reason is that the absolute path of the object file (assembly.ll) is hard-coded as part of the generated run.istats. To fix this, assume that the file is local to the `run.istats`.

2019-12-12[Searchers] Remove weight from es, add nurs_depthTimotej Kapus
Having both weight and depth in execution state is wasteful, therefore this patch removes weight. The nurs:depth searcher is replaced by nurs:rp, which uses pow to compute the weight A new nurs:depth searcher is introduced that biases the search with depth, making it the only other searcher that prefers to go deep (similar to dfs).

2019-11-05Core: Executor, remove unused variableJiri Slaby
numSeeds is unused since commit 4eb050e2999b (ExecutorTimers: refactor and move to support lib), so remove it.
2019-11-05Mark all constant global memory objects as constantMartin Nowack
Fixes #264. We first aggregate all constant memory objects initialise them and initialise their counter parts in the concrete memory. After that, we mark memory objects as constant such that they can't be modified (i.e. this includes marking them symbolic).

2019-07-30Consolidated Expr-related include files into a single include/klee/Expr ↵Cristian Cadar
directory. This improves the organization of the code, and also makes it easier to reuse Expr outside KLEE.
