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.

2016-03-05Fix SELinux signatures in runtimeLaszlo Szekeres
The SELinux function signatures have changed between version 2.2 and 2.3. In particular, the type of the "security context" parameter was changed from char * to const char *, with the following patch: SELinuxProject/selinux@9eb9c9327563014ad6a807814e7975424642d5b9. Recent Linux distributions (e.g. Ubuntu 15.10) ship with the updated version of libselinux. This change makes the SELinux runtime compatible with the newer versions of the library by replacing security_context_t with its original char * definition and defining it as const only if the installed library does so. Whether the system uses const char * types is detected with the configure script. Fixes klee/klee#303.
2015-06-03Added an option --readable-posix-inputs which is used to turn on/off the CEX ↵Cristian Cadar
preferences added in the POSIX model. Removed option --prefer-cex which controlled all CEX preferences.

2015-04-25Clean up the installation/building of the runtime libraries.Dan Liew
* We don't need to build the native versions so that is now disabled * We don't need to install (and hence build) the bytecode archive library versions of klee-libc or kleeRuntimeIntrinsic for new versions of LLVM right now (this is kind of messy).

2014-01-09Fixed race condition in parallel build where a symbolic linkDan Liew
(for klee-uclibc) would be created before the destination directory existed.
2013-12-21klee-uclibc detection is now a lot cleaner. KLEE now assumesDan Liew
it can find klee-uclibc inside the same folder as the other runtime libraries with the name "klee-uclibc.bca" This is implemented as follows: * When building, a sym-link is created to klee-uclibc's libc.a file in the same directory that the rest of KLEE's runtime libraries are built. This done so that if a developer changes klee-uclibc on their system then the correct version of klee-uclibc is used by KLEE. * When installing, klee-uclibc's libc.a file is installed in the same directory that the rest of KLEE's runtime libraries are installed. In addition the configure script argument --with-uclibc can now operate in two ways. It can either be passed the path to the root of klee-uclibc or it can be passed a path to the libc.a file built by klee-uclibc. This new behaviour has been added to allow users to potential use pre-built versions of klee-uclibc.

2013-08-27Port to LLVM 3.3Martin Nowack
Major changes are: - Switching to llvm-link to build archive files - Use GetMallocUsage instead of GetTotalMemoryUsage (be aware of bug in LLVM 3.3 http://llvm.org/bugs/show_bug.cgi?id=16847) - intrinsic library functions like memcpy/mov/set use weak linkage to be replaced by e.g. uclibc functions - rewrote linking with library - enhanced MemoryLimit test case to check if mallocs were successful

2012-10-24Patch by Dan Liew: " Added "sys/resource.h" include to POSIX stubCristian Cadar
methods. This fixes build problems (at least on my machine glibc 2.16.0-2) The __priority_which_t and __rlimit_resource_t data types which functions set_priority(), setrlimit() and setrlimit64() need are not defined in any of the headers the runtime/POSIX/stubs.c includes. It appears in the past the "sys/resource.h" was included by "sys/wait.h" but in the recent version of glibc I am using it is not. So to fix this I've added the include." git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@166554 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-11This is a workaround for the infinite loop reported at Cristian Cadar
http://keeda.stanford.edu/pipermail/klee-dev/2011-August/000723.html KLEE needs to use --fno-builtin when compiling its version of memset. However, this patch also adds the workaround suggested by Paul in the thread above, since support for --fno-builtin was added to llvm-gcc only after LLVM 2.9 was released.
