2017-03-30[CMake] Add the `clean_runtime` top level target to provide an easy wayDan Liew
to clean the runtime build. Unfortuantely there is no way to have the `clean` target trigger the `clean_runtime` target unfortunately.
2017-01-18[CMake] Remove `ENABLE_TESTS` CMake cache option.Dan Liew
The intention of this option was to provide a switch that can be used to globally enable/disable tests. This option ended up causing a lot of confusion as can be seen on the discussion on writing documention for the new build system. https://github.com/klee/klee.github.io/pull/53 So it was decided to remove this option. This fixes #568 .
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.
2016-11-19[CMake] Document implicit `STP_DIR` and `metaSMT_DIR` options.Dan Liew
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.
