2020-12-04llvm11: CallBase::getParamAlignment has been deprecatedLukas Zaoral
and should be replaced with CallBase::getParamAlign
2020-12-04llvm11: GlobalValue::getAlignment has been removedLukas Zaoral
See: https://reviews.llvm.org/D80368
2020-12-04llvm11: Composite and Sequential types were removedLukas Zaoral

2020-12-04llvm11: Use getCalledOperand instead of getCalledValueLukas Zaoral
CallBase::getCalledValue has been deprecated by getCalledOperand since LLVM 8 and has been removed in LLVM 11 See: https://reviews.llvm.org/D78882
2020-12-04llvm11: Make conversions from StringRef to std::string explicitLukas Zaoral
The same applies to SmallString. See: llvm/llvm-project@777180a#diff-497ba4c0c527a125d382b51a34f32542

Currently, only 32bit vs. 64bit is supported.

2020-10-12Exception handling only for LLVM >= 8.0.0Julian Büning
2020-10-12use isa<> and explicit nullptr-check for compilation with older LLVM ↵Felix Rath
versions, also mark two errors as ExecErrors, as these should not be caused by users
2020-10-12Implemented support for C++ ExceptionsFelix 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>
2020-10-09implement fneg instructionJulian Büning
2020-10-09fix: fabs() working on the wrong argumentDavid Laprell
2020-09-26Replace 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.
2020-09-03Guard process-tree compression with a command-line switchSebastian Poeplau
2020-09-03Fix PTree::remove to clean the tree properlySebastian Poeplau
The previous version left unnecessary intermediate nodes behind, sometimes leading to very long paths in the tree.
2020-09-02More robust handling of unknown intrinsicsAlastair 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.
2020-08-19DiscretePDF: use IDs instead of pointers (see PR #739)Frank Busse
2020-07-30introduce --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.
2020-07-01Remove state contructor with constraintsMartin Nowack
This constructor has been a hack and was wrongly used, use ConstraintManager instead. Allow copy-constructing states only via `ExecutionState::branch()` call.
2020-07-01Use constraint sets and separate metadata for timing solver invocationMartin 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)
2020-07-01Use `unique_ptr` for solver in timing solverMartin Nowack
2020-07-01Separate constraint set and constraint managerMartin Nowack
2020-06-29Enable subsets for RandomPathSearcherTimotej Kapus
2020-06-29[PTree] Replace left/right with PointerIntPairTimotej Kapus
2020-06-29Revert "refactor PTree: use unique_ptr"Timotej Kapus
This reverts commit 0aed7731210d0eb41c0ea767edb8067130cf6252.
2020-06-29Implement fshr/fshl intrinsicsAlastair Reid
Changes: - IntrinsicCleaner accepts fshr/fshl as accepted intrinsics - Executor::executeCall converts fshr/fshl to urem/zext/concat/shift/extract - Klee/main suppresses warnings about externals that are LLVM reserved (i.e., begin with "llvm.") - New test exercises 32 and 7 bit versions including oversize shift values Test values are based on LLVM's test for fshl/fshr - Changes that depend on existence of fshr/fshl are guarded by #if LLVM_VERSION_CODE >= LLVM_VERSION(7, 0) or ; REQUIRES: geq-llvm-7.0
2020-06-25Enforce fork/branch limits in branch() and fix double terminationFrank Busse
* extend help messages for -max-memory and -max-memory-inhibit * introduces branchingPermitted() * enforces fork/branch limits in branch() (vector version) * changes main loop * calls updateStates() before checkMemoryUsage() * calls updateStates() again in case we early terminate states This should prevent double termination for now. Other solutions are imho more expensive as we would have to compare possibly large vectors of states (either states(arr) in checkMemoryUsage() or removedStates in terminateState()).

2020-06-25ExecutorUtil: assert that GlobalValue is already knownJulian Büning
2020-06-24StatsTracker: initialize indexed stats when user searcher requires MD2UAdrian Herrera
This is the same check used in Executor::setModule. Without this check, KLEE will segfault in StatisticsManager::incrementIndexedValue, getIndexedValue, and setIndexedValue when `-output-stats=false` or `-output-istats=false` because StatisticsManager::indexedStats has not been allocated.
2020-06-24print stateID with --debug-print-instructionsFrank Busse
2020-06-24add ExecutionState IDsFrank Busse
* add getID()/setID() * use ExecutionStateIDCompare in Executor::states set * output state id in .err files

"Instruction *i" declared at the beginning of the function. Reformatted this function.
