2024-02-08Replace `%libcxx_include` with `%libcxx_includes` for multi-include directoriesMartin Nowack
To support multiple include directories for c++ header files, use `%libcxx_includes`. This string contains the `-I` compiler directive for each include path as well. Update test cases to use new directive.
2024-01-12new: persistent ptree (-write-ptree) and klee-ptreeFrank Busse
Introduce three different kinds of process trees: 1. Noop: does nothing (e.g. no allocations for DFS) 2. InMemory: same behaviour as before (e.g. RandomPathSearcher) 3. Persistent: similar to InMemory but writes nodes to ptree.db and tracks information such as branch type, termination type or source location (asm) in nodes. Enabled with -write-ptree ptree.db files can be analysed/plotted with the new "klee-ptree" tool.
2023-03-22Explicitly check if 32bit support is enabled for testingMartin Nowack
Ignore test in the first place, if no 32bit is enabled.
2022-03-17remove LLVM < 6 from build/test scriptsFrank Busse
2022-03-09tests: make UBSAN print stack tracesLukáš Zaoral
2020-10-12Exception handling only for LLVM >= 8.0.0Julian 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
2019-03-17Fix libc++ testcasesMartin Nowack
* remove wrapper script invocation and script * add build instruction to test cases * added additional checks * add check to avoid execution of tests if KLEE is not compiled with libc++
2019-03-17Added libcxx flagLukas Wölfer
2019-03-12Add support to compile KLEE with MemorySanitizer (MSan)Martin Nowack
2019-03-07tests: rename xxclang to clangxxFrank Busse
2019-03-07Renamed %llvmgcc and %llvmgxx to %clang and %clangxx respectively.Cristian Cadar
2018-11-06fix: actually set -O0 in test/concrete/CMakeLists.txtJulian Büning
`-O0` has to be used in conjunction with, not instead of `-Xclang -disable-O0-optnone`
2018-10-26llvm5: test, add -disable-O0-optnone to -O0Jiri Slaby
Otherwise optimizations done in klee won't have any effect. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

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.
2016-02-14Try to fix the TravisCI build when using Z3 as the solver. TheDan Liew
``test/Feature/SolverTimeout.c`` test fails there. The error message I see in TravisCI is ``` Command 2: "/home/travis/build/klee/build/klee/Release+Asserts/bin/klee" "--output-dir=/home/travis/build/klee/build/klee/test/Feature/Output/SolverTimeout.c.tmp.klee-out" "--max-solver-time=1" "/home/travis/build/klee/build/klee/test/Feature/Output/SolverTimeout.c.tmp1.bc" Command 2 Result: -11 Command 2 Output: Command 2 Stderr: KLEE: output directory is "/home/travis/build/klee/build/klee/test/Feature/Output/SolverTimeout.c.tmp.klee-out" KLEE: WARNING: undefined reference to function: printf KLEE: ERROR: (location information missing) divide by zero KLEE: NOTE: now ignoring this error at this location 0 klee 0x0000000000da87d2 llvm::sys::PrintStackTrace(_IO_FILE*) + 34 1 klee 0x0000000000da85c9 2 libpthread.so.0 0x00007fca19936cb0 3 libz3.so 0x00007fca19079826 4 librt.so.1 0x00007fca1747640c 5 libpthread.so.0 0x00007fca1992ee9a 6 libc.so.6 0x00007fca1776c38d clone + 109 ``` The issue appears to be racey as I had to run several copies of KLEE in parallel for the bug to occur using Z3 4.4.1. I managed to get a coredump and got the backtrace from gdb for the crash which is ``` #0 0x00007f4841b11c46 in scoped_timer::imp::sig_handler (s=..., s@entry=...) at ../src/util/scoped_timer.cpp:112 #1 0x00007f484031e0ff in timer_sigev_thread (arg=0x7f48380008c0) at ../nptl/sysdeps/unix/sysv/linux/timer_routines.c:63 #2 0x00007f484291c182 in start_thread (arg=0x7f483db46700) at pthread_create.c:312 #3 0x00007f484061b47d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:111 ``` The crash appears to be in Z3 itself but I can't reproduce the issue when using the version of Z3 from the master branch. For now we simply workaround the issue by not running the ``test/Feature/SolverTimeout.c`` test when using Z3 as the solver. We should revisit this issue when another stable release of Z3 is made.
2014-09-13[tests] Add support for testing LLVM version in REQUIRES: and XFAIL: lines.Daniel Dunbar
- You can now make tests disabled, or expected to fail, by writing something like: // XFAIL: llvm-3.4 or // REQUIRES: not-llvm-3.4 - This mechanism doesn't support version comparisons, it is mostly intended to help with switching over to new LLVM versions and incrementally working through the test failures.
2014-04-14Update to new lit configuration to support changes in LLVM3.4Martin Nowack
2014-01-20Only run SELinux test if support for SELinux was detected at configureDan Liew
time.
2014-01-20Removed all of llvm-lit's dependence on DejaGNU. A few thingsDan Liew
are now broken and will be fixed shortly.
2014-01-20Allow llvm-lit from 2.9 to work by hacking %T substitution variable.Dan Liew
2014-01-20Add LLVM tool directory to PATH when running tests with llvm-lit.Dan Liew
This is needed because the helper tool 'not' is used by some tests
2010-05-02Sketch support for running KLEE tests using 'lit'.Daniel Dunbar
- Not working yet. Also, ditch a bunch of unused substitution variables from the site.exp config file. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@102872 91177308-0d34-0410-b5e6-96231b3b80d8
