2022-03-17remove LLVM < 6 from sourcesFrank Busse
2022-03-09Core/Executor: Fix unaligned write of fp80 argumentsLukáš Zaoral
... in Executor::callExternalFunction. Fixes the following error reported in Feature/VarArg{Alignment,LongDouble}.c tests: lib/Expr/Expr.cpp:366:5: runtime error: store to misaligned address 0x7ffc011d3528 for type 'long double', which requires 16 byte alignment
2022-03-09Core/ExecutionState: Fix uninitialized reads in unit testsLukáš Zaoral
... by initialising all members of fundamental types of the ExecutionState class. Fixes the following error in SearcherTest.{Two,}RandomPath unit tests: lib/Core/ExecutionState.cpp:114:22: runtime error: load of value 254, which is not a valid value for type 'bool'
2022-01-07stats: remove reachableUncovered (unused)Frank Busse

2021-12-23Introduce termination categoriesFrank Busse
Track all path terminations: esp. for debugging or visualising a persistent process tree (with or without full MoKlee integration) it is helpful to know the exact reason (StateTerminationType) why a path terminated.

2021-11-02Core/Executor: use `nullptr` instead of `0`ᴀᴇꜱᴏᴘʜᴏʀ
Since KLEE requires C++14, we should prefer `nullptr` to plain `0`.
2021-09-10llvm12: Implement llvm.abs intrinsicLukas Zaoral
The vector variants are not implemented at the moment. See: https://reviews.llvm.org/D84125 Co-authored-by: Lukas Zaoral <lzaoral@redhat.com> Co-authored-by: Martin Nowack <m.nowack@imperial.ac.uk>

2021-09-10llvm12: VectorType::getNumElements() has been deprecatedLukas Zaoral
... and has already been removed from the LLVM 13 source tree. See: https://reviews.llvm.org/D78127 https://reviews.llvm.org/D95570
2021-05-10allocate memory objects for functionsJulian 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.

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)

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.
