| 2023-03-20 | ConstantArrayExprVisitor: Fix detection of multiple array indices | Lukáš Zaoral | |
| Previously, the code did two consecutive checks. First one succeeded only if the given index was not already seen and the second one did an analogous check but for arrays. However, if the given index usage was already detected for some array, its usage for another array that already had some other index detected would be silently skipped and the `incompatible` flag would not be set. Therefore, if the code contained e.g. the following conditional jump on two arrays with two symbolic indices, the multi-index access would remain undetected: if ((array1[k] + array2[x] + array2[k]) == 0) Resulting in the following output: KLEE: WARNING: OPT_I: infeasible branch! KLEE: WARNING: OPT_I: successful | |||
| 2023-03-20 | llvm14: PointerType::getElementType() was deprecated | Lukáš Zaoral | |
| ... for LLVM 14 in [1] and has already been removed from the LLVM 15 branch in [2]. Some changes are only temporary to silence the warning though, as Type::getPointerElementType() is planned to be removed as well.

| 2021-12-23 | Introduce termination categories | Frank Busse | |
| Track all path terminations: esp. for debugging or visualising a persistent process tree (with or without full MoKlee integration) it is helpful to know the exact reason (StateTerminationType) why a path terminated. | |||

| 2020-08-07 | New intrinsic: klee_is_replay | Alastair Reid | |
| This instrinsic detects whether the program is being executed symbolically or concretely (i.e., using the libkleeRuntest library). The intended usage (illustrated in the test program) is to allow the test program to display the input values by invoking any libraries it wants to. This is especially valuable if you are constructing complex, structured values and for languages like Rust (or C++) that have rich libraries and print libraries. For example, you might pick a symbolic value N with the assumption "0 <= N < 10" and then pick N symbolic values and write them to an array. The resulting ktest file is a bit hard to understand compared with the output of the standard print function in Rust/C++. | |||
| 2020-07-30 | introduce --rng-initial-seed=<unsigned> | Frank Busse | |
| * move global theRNG into Executor * pass theRNG via ctor to searchers * remove some type warnings from RNG.cpp Fixes #1023. | |||
| 2020-07-29 | remove holes in Instruction-/FunctionInfoTable, add documentation | Frank Busse | |
| 2020-07-01 | Clean-up and add documentation | Martin Nowack | |
| 2020-07-01 | Use constraint sets and separate metadata for timing solver invocation | Martin Nowack | |
| Decouple ExecutionState from TimingSolver Instead of providing an execution state to the timing solver use a set of constraints and an additional object for metadata. Fixes: * correct accounting of metadata to a specific state * accounting of all solver invocations (e.g. solver-getRange was not accounted) * allows to invoke the solver without a state (avoids costly copying of states/constraints) | |||

| 2020-02-19 | Use `ref<>` for MemoryObject handling | Martin Nowack | |
| This uses the `ref<>`-based memory handling of MemoryObjects. This makes it explicit that references are held in: - ExecutionState::symbolics - ObjectState | |||

| * Replace c header with c++ header * remove unneeded header file | |||
| 2020-02-19 | Add move assignment operator and move construct for `ref` class. | Martin Nowack | |
| 2020-02-19 | Add `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. | |||
| 2020-02-19 | Fix ptr reference invalidation if last reference gets freed before new ↵ | Martin Nowack | |
