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.

2021-02-22runtime/POSIX: fix failures with glibc-2.33Jiri Slaby
commit 8ed005daf0ab of glibc-2.33 (Remove stat wrapper functions, move them to exported symbols) removed renames of `__fxstat`, `__xstat`, and `__lxstat` to `__fxstat64`, `__xstat64`, and `__lxstat64`, respectively. But we relied on the renames to build `fd_64.c` properly. With glibc 2.33, we now see link failures of the POSIX runtime: error: Linking globals named '__xstat': symbol multiply defined! Rename the functions using `__REDIRECT_NTH` in the code as `__USE_FILE_OFFSET64` case (which we define at the top of the file by `#define _FILE_OFFSET_BITS 64`) did exactly that. Fixes #1384.
