2021-02-16Executor: remove obsolete special case for __cxa_{re,}throwJulian Büning
__cxa_throw and __cxa_rethrow were not handled by special function handlers in the final version of #966 (which introduced support for C++ exception handling)

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

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

2020-10-09Replace `NULL` with explicit `nullptr`Martin Nowack
2020-10-09Explicitly track global variables in getDirectCallTargetMartin Nowack
Global variables can't be a direct call target. Their values are read and treated as indirect call targets.
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

2020-06-29Implement 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()).
