2022-03-17Fixed GetTotalMallocUsage on macOS to look at all zones. (The test ↵Cristian Cadar
MemoryLimit.h fails on macOS 12.1 without this fix.)
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
2022-01-06Comment the code dealing with un/flushed bytes, and resolve old naming issue ↵Cristian Cadar

2022-01-05Remove outdated reference to klee_make_symbolic_nameCristian Cadar
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.

2021-12-20llvm13: llvm::fs::F_None has been removedLukas Zaoral
... and should be replaced with llvm::fs::OF_None since LLVM 7. See: https://reviews.llvm.org/D101506 https://github.com/llvm/llvm-project/commit/1f67a3cba9b09636c56e2109d8a35ae96dc15782
2021-12-20Support/FileHandling.cpp: rewrite to C++14Lukas Zaoral
2021-11-20Fixed fail with preferCex, removed relation from first argumentTaras Bereznyak
2021-11-02Core/Executor: use `nullptr` instead of `0`ᴀᴇꜱᴏᴘʜᴏʀ
Since KLEE requires C++14, we should prefer `nullptr` to plain `0`.
2021-10-27Module/RaiseAsm: Support i686 target as wellLukas Zaoral
Add i686 to the list of supporterd targets by this transformation pass.
2021-10-27Module/RaiseAsm: Fix crash when host and bitcode target triples differLukas Zaoral
RaiseAsm always created a target machine for the host target and not for the bitcode one. Therefore, KLEE could crash on i686 bitcode as x86_64 target machine cannot be used to raise i686 assembly. Fixes: LLVM ERROR: 64-bit code requested on a subtarget that doesn't support it!
2021-09-10llvm12: Implement llvm.abs intrinsicLukas Zaoral

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.
