2023-03-22Change `llvm_map_components_to_libnames` to `llvm_config` CMake functionMartin Nowack
With recent LLVM versions, this should allow to link against dynamic LLVM libraries.
2023-03-17[cmake] Use LLVM's CMake functionality onlyMartin Nowack
LLVM became more complex, use LLVM's CMake functionality directly instead of replicating this behaviour in KLEE's build system. Use the correct build flags provided by LLVM itself. This is influenced by the way LLVM is built in the first place. Remove older CMake support (< 3.0).

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.
2020-12-02Detect system include headers on macOSMartin Nowack
System header files on macOS are not part of `/usr/include` since Catalina. Instead, multiple locations are possible and depend on the selected SDK. Use `xcrun` to automatically detect the correct path on macOS.
2020-11-04[cmake] Remove several leftovers from old autoconf build systemMartin Nowack
2019-09-05test/CMakeLists.txt: error handling for downloadJulian Büning
2019-09-05test/CMakeLists.txt: use official llvm monorepo for downloadJulian Büning
2019-07-30fix two test issuesFelix Rath
* Add 'uclibc'-feature for testing if it is enabled * -> allow tests to depend on uclibc-availability * ENABLE_UCLIBC was redundant, use SUPPORT_KLEE_UCLIBC instead * Cleaned up 'libcxx'-feature availability detection
2019-07-30Add missing dependencies for `check` targetMartin Nowack
Build `gen-bout` and `gen-random-bout` before running tests
2018-10-08add support for klee-replay on OSXFrank Busse
* also adds klee-replay as dependency for systemtests

2017-03-17test: fix 'not' buildJiri Slaby
There was a typo and 'not' utility was tried to be built with FileCheck's libraries. But those can be undefined. Fix this by using the correct variable. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2017-01-19Teach both build systems to pass the user provided CXXFLAGS and CFLAGSDan Liew
when using the native compiler in system tests. This fixes the `libkleeruntest` tests when building with ASan.
2017-01-16[CMake] Rename "integrationtests" to "systemtests".Dan Liew
This was a proposal from #500. @andreamattavelli pointed out that the lit tests are really system tests rather than integration tests so this commit fixes the inappropriate naming that I chose.
2017-01-14Write tests to test `libkleeRuntest`. The `replay_posix_runtime.c`Dan Liew
test is marked XFAIL because there is a bug in the implementation of `libkleeRuntest`. Quite a few changes had to be made to the lit configuration in order to support these tests. To run the tests I had to fix #480 for the autoconf/Makefile build system otherwise the `libkleeRuntest` library would not be found by the system linker at runtime.
2016-11-07Implement a CMake based build system for KLEE.Dan Liew
This is based off intial work by @jirislaby in #481. However it has been substantially modified. Notably it includes a separate build sytem to build the runtimes which is inspired by the old build system. The reason for doing this is because CMake is not well suited for building the runtime: * CMake is configured to use the host compiler, not the bitcode compiler. These are not the same thing. * Building the runtime using `add_custom_command()` is flawed because we can't automatically get transitive depencies (i.e. header file dependencies) unless the CMake generator is makefiles. (See `IMPLICIT_DEPENDS` of `add_custom_command()` in CMake). So for now we have a very simple build system for building the runtimes. In the future we can replace this with something more sophisticated if we need it. Support for all features of the old build system are implemented apart from recording the git revision and showing it in the output of `klee --help`. Another notable change is the CMake build system works much better with LLVM installs which don't ship with testing tools. The build system will download the sources for `FileCheck` and `not` tools if the corresponding binaries aren't available and will build them. However `lit` (availabe via `pip install lit`) and GTest must already be installed. Apart from better support for testing a significant advantage of the new CMake build system compared to the existing "Autoconf/Makefile" build system is that it is **not** coupled to LLVM's build system (unlike the existing build system). This means that LLVM's autoconf/Makefiles don't need to be installed somewhere on the system. Currently all tests pass. Support has been implemented in TravisCI and the Dockerfile for building with CMake. The existing "Autoconf/Makefile" build system has been left intact and so both build systems can coexist for a short while. We should remove the old build system as soon as possible though because it creates an unnecessary maintance burden.
