| 2021-09-10 | llvm12: VectorType::getNumElements() has been deprecated | Lukas Zaoral | |

| 2021-05-10 | allocate memory objects for functions | Julian Büning | |
| Before, we reused the llvm::Function* value in the target program, even though it stems from KLEE's own address space. This leads to non-deterministic function pointers, even with --allocate-determ. This issue was identified in the MoKLEE paper. Now, we allocate a memory object per function, for its (potentially) deterministic address. Mapping this address back to llvm::Functions is done by the legalFunctions map. Also, pointer width now depends on the target, not the host. | |||

| 2020-11-04 | Link to the different runtime libraries depending on the application to test. | Martin Nowack | |

| 2020-10-12 | Implemented support for C++ Exceptions | Felix Rath | |
| We implement the Itanium ABI unwinding base-API, and leave the C++-specific parts to libcxxabi. Co-authored-by: Lukas Wölfer <lukas.woelfer@rwth-aachen.de> | |||
| 2020-10-09 | implement fneg instruction | Julian Büning | |
| 2020-10-09 | fix: fabs() working on the wrong argument | David Laprell | |
| 2020-10-09 | Replace `NULL` with explicit `nullptr` | Martin Nowack | |
| 2020-10-09 | Explicitly track global variables in getDirectCallTarget | Martin Nowack | |
| Global variables can't be a direct call target. Their values are read and treated as indirect call targets. | |||
| 2020-09-26 | Replace llvm::CallSite with llvm::CallBase on LLVM 8+ | Lukas Zaoral | |
| This is in preparation for LLVM 11 as the llvm:CallSite class has been removed. | |||
| 2020-09-03 | Guard process-tree compression with a command-line switch | Sebastian Poeplau | |
| 2020-09-03 | Fix PTree::remove to clean the tree properly | Sebastian Poeplau | |
| The previous version left unnecessary intermediate nodes behind, sometimes leading to very long paths in the tree. | |||
| 2020-09-02 | More robust handling of unknown intrinsics | Alastair Reid | |
| - If an unknown intrinsic appears in the bitcode file, it is reported but execution can proceed. - If an unknown intrinsic is encountered during execution of some path, - the intrinsic is reported - this path is treated as an error - execution of other paths can proceed To be more precise, there is a list of "known unknown intrinsics". Intrinsics not on this list will prevent execution. | |||
| 2020-08-19 | DiscretePDF: use IDs instead of pointers (see PR #739) | Frank Busse | |
| 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 | Remove state contructor with constraints | Martin Nowack | |
| This constructor has been a hack and was wrongly used, use ConstraintManager instead. Allow copy-constructing states only via `ExecutionState::branch()` call. | |||
| 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) | |||
| 2020-07-01 | Use `unique_ptr` for solver in timing solver | Martin Nowack | |
| 2020-07-01 | Separate constraint set and constraint manager | Martin Nowack | |
