2021-12-20test/Concrete/GlobalUndef.ll: Remove `target datalayout` and `target triple`Lukáš Zaoral
Fixes assertion violation triggered in LLVM 13 CI job due to incompatibility with default target triple and datalayout.

2021-12-20llvm13: llvm::cl::GeneralCategory is no longer a globalLukas Zaoral
Therefore, llvm::cl::getGeneralCategory() should be used instead. See: https://reviews.llvm.org/D105959
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
2021-12-19cmake: copy klee-uclibc and klee-libcxx to expected locationsLukas Zaoral
Before this change, we created a symlink to the given libraries in their expected location and then installed the original library. This was problematic as the install directives are performed the order they are encountered during the configure step and the installation of directory containing the symlink was processed after the installation of the original library. Therefore, the original libraries were installed but were subsequently overwritten by the symlinks that can become broken rather easily. This commit changes the behaviour so that we create copy the libraries to the expected location and install them together with the rest of the KLEE runtime as was originally intended.

2021-10-27tools/klee: Warn if module and host target triples differLukas Zaoral
... as running a bitcode with a different target triple may result in unexpected crashes or assertion violations.
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!

2021-10-17test/Runtime/POSIX/Futimesat: Compile with -std=c99Lukas Zaoral
.. so that `linux` is not a defined macro. Without the `-std=c99` option, linux is an implicitly defined macro so all such substrings in the given path will be replaced with `1` during stringification. Unfortunately, Fedora's rpmbuild uses `x86_64-redhat-linux-gnu` as a build directory for all CMake projects which leads to a failure due to a change to `x86_64-redhat-1-gnu`. Fixes: #1424
2021-10-13test/Feature/FunctionAlias.c: Add missing CHECK-UNKNOWN prefixLukas Zaoral
This test started to fail on LLVM 13 because FileCheck switched the default setting regarding the allowance of unused prefixes. This is now considered to be a fatal error.

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.
2021-05-10extend function pointer testJulian Büning
Part of the test was already disabled in the initial checkin. However, we do support function pointers if they are restricted to one or more possible values.

2021-04-18tests: Do not add klee tools to PATH in litLukas Zaoral
It may happen that some older instance of klee is already present in PATH. All tests that call plain klee instead of %klee may use it and then unexpectedly fail. This commit will make all tests that rely on klee tools being explicitly in PATH fail in our CI. From now on, only LLVM tools, FileCheck and not will be in lit's PATH.
2021-04-08cmake: Fix CMP0026 policy deprecation warningLukas Zaoral
CMake 3.19+ started to issue warnings if this policy is set to OLD: CMake Deprecation Warning at test/CMakeLists.txt:143 (cmake_policy): The OLD behavior for policy CMP0026 will be removed from a future version of CMake. The cmake-policies(7) manual explains that the OLD behaviors of all policies are deprecated and that a policy should be set to OLD only under specific short-term circumstances. Projects should be ported to the NEW behavior and not rely on setting a policy to OLD.
