| 2024-02-08 | Disable unsupported passes for newer LLVM versions | Martin Nowack | |

| 2024-02-08 | Refactor invocation of old pass manager into legacy function | Martin Nowack | |
| 2024-01-30 | Change `GetConstraintLog` to work with `std::string`s instead of `char*`s | Daniel Schemmel | |
| 2024-01-30 | Avoid generating array names in solver builders that could accidently collide | Martin Nowack | |
| If an array name ended with a number, adding a number-only suffix could generate the same name used as part of the solvers. In the specific testcase `val_1` became solver array `val_111` which collided with array `val_11` that became `val_111` as well. Using an `_` as prefix for the suffix, solves that problem in general, i.e. `val_1` becomes `val_1_11` and `val_11` becomes `val_11_1`. Fixes #1668 | |||

| 2024-01-30 | Removed --zero-seed-extension, and merge it with --allow-seed-extension. ↵ | Cristian Cadar | |
| This reworked logic also fixes a buffer overflow which could be triggered during seed extension. | |||
| 2024-01-30 | Refactored some code related to seeding. | Cristian Cadar | |
| 2024-01-30 | On a symbolic allocation, retrieve size from a seed, if available | Cristian Cadar | |
| 2024-01-30 | Concretize arguments to external function calls using seeds, if available. ↵ | Cristian Cadar | |
| Added a test case. | |||
| 2024-01-30 | Concretize constants using seed values, when available. Added two tests (w/ ↵ | Cristian Cadar | |
| and w/o seed extension) based on FP concretization. | |||
| 2024-01-12 | Follow-up: applied review comments, implemented meta-data cleanup (one more ↵ | Tomasz Kuchta | |

| 2024-01-12 | Feature: implement single memory object resolution for symbolic addresses. | Tomasz Kuchta | |
| This feature implements tracking of and resolution of memory objects in the presence of symbolic addresses. For example, an expression like the following: int x; klee_make_symbolic(&x, sizeof(x), "x"); int* tmp = &b.y[x].z; For a concrete array object "y", which is a member of struct "b", a symbolic offset "x" would normally be resolved to any matching memory object - including the ones outside of the object "b". This behaviour is consistent with symbex approach of exploring all execution paths. However, from the point of view of security testing, we would only be interested to know if we are still in-bounds or there is a buffer overflow. The implemented feature creates and tracks (via the GEP instruction) the mapping between the current symbolic offset and the base object it refers to: in our example we are able to tell that the reference should happen within the object "b" (as the array "y" is inside the same memory blob). As a result, we are able to minimize the symbolic exploration to only two paths: one within the bounds of "b", the other with a buffer overflow bug. The feature is turned on via the single-object-resolution command line flag. A new test case was implemented to illustrate how the feature works. | |||
| 2024-01-12 | Renamed PTree to ExecutionTree (and similar) | Cristian Cadar | |
| 2024-01-12 | Rename files from PTree to ExecutionTree (and similar) | Cristian Cadar | |
| 2024-01-12 | new: persistent ptree (-write-ptree) and klee-ptree | Frank Busse | |
| Introduce three different kinds of process trees: 1. Noop: does nothing (e.g. no allocations for DFS) 2. InMemory: same behaviour as before (e.g. RandomPathSearcher) 3. Persistent: similar to InMemory but writes nodes to ptree.db and tracks information such as branch type, termination type or source location (asm) in nodes. Enabled with -write-ptree ptree.db files can be analysed/plotted with the new "klee-ptree" tool. | |||
| 2023-09-11 | Make KDAlloc the default memory allocator | Cristian Cadar | |
| 2023-09-07 | Remove broken experimental optimisation for validity (--cex-cache-exp) | Cristian Cadar | |
| 2023-07-21 | Add code to only keep in the --help menu the KLEE/Kleaver option categories | Cristian Cadar | |
| 2023-07-21 | Move some options to the klee namespace and declare them in OptionCategories.h | Cristian Cadar | |
| 2023-07-12 | Replaced --suppress-external-warnings and --all-external-warnings with ↵ | Cristian Cadar | |
| --external-call-warnings=none|once-per-function|all. This eliminates the ambiguity when both of the old options were set. Added test for the new option. | |||
| 2023-07-08 | Combine all `ConstantExpr::toMemory` cases into one. | Daniel Schemmel | |
| Note that (as it did previously), this relies on the native types having the same internal representation as the ApInt type. | |||

| 2023-06-05 | make BatchingSearcher more readable | Julian Büning | |
| 2023-06-05 | fix BatchingSearcher's disabled time budget | Julian Büning | |
| The functionality of the batching searcher that increases the time budget if it is shorter than the time between two calls to `selectState()` ignored the disabled time budget. Effectively, the batching searcher thus picks a very arbitrary time budget on its own. | |||
