| 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 | |||
| 2020-02-19 | Use `ref<>` for UpdateNode | Martin Nowack | |
| Remove additional reference counting as part of UpdateNodeList and UpdateNode. Simplifies code. | |||
| 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. | |||
| 2020-01-19 | Remove 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. | |||
| 2020-01-13 | Assume assembly.ll is local to the run.istats file | Martin 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`. | |||
| 2019-12-13 | Remove unnecessary std::move's that prevent copy elision | Cristian Cadar | |
| 2019-12-12 | [Searchers] Remove weight from es, add nurs_depth | Timotej 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). | |||
| 2019-11-28 | Move merging related code from Executor into MergingSearcher | Lukas Wölfer | |

| 2019-11-05 | Core: Executor, remove unused variable | Jiri Slaby | |
| numSeeds is unused since commit 4eb050e2999b (ExecutorTimers: refactor and move to support lib), so remove it. | |||
| 2019-11-05 | Mark all constant global memory objects as constant | Martin 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). | |||
