~cnx/klee - KLEE fork for patch differentiation testing

Age	Commit message (Collapse)	Author
2019-03-07	Renamed %llvmgcc and %llvmgxx to %clang and %clangxx respectively.	Cristian Cadar

2018-10-26	llvm5: test, add -disable-O0-optnone to -O0	Jiri Slaby
	Otherwise optimizations done in klee won't have any effect. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-08-03	Fixed runtest library to handle the case of a NULL "name" argument in ↵	Cristian Cadar
	klee_make_symbolic. Changed a test case to check this feature.
2018-05-01	Ensured program reliably has 3 paths to be explored, and removed unnecessary ↵	Cristian Cadar
	options. Make klee_abort() call abort() in replay, and removed trivial test which cannot be easily integrated into the test suite.
2018-05-01	Implement klee_prefer_cex() and klee_abort() in Runtest and added ↵	lyxia
	corresponding tests
2017-07-24	Moved klee_choose from klee-libc to KLEE intrinsics.	Cristian Cadar

2017-02-14	Fix linker compatibility under macOS	Andrea Mattavelli

2017-01-14	Change how error handling is done in libkleeRuntest.	Dan Liew
	Previously error messages would be emitted but execution would continue which might not be desirable. Now a wrapper function (for fprintf) `report_internal_error()` is used which will cause the program to exit. The older behaviour of continuing to execute after an error can be achieved by setting a new environment variable `KLEE_RUN_TEST_ERRORS_NON_FATAL`. This commit also adds a test for each error case.
2017-01-14	Fix bug reported privately by @danielschemmel .	Dan Liew
	If KLEE generates ktest files with `--posix-runtime` then if replaying using libkleeRuntest then replay would be incorrect because the `model_version` object would be unintentionally used during replay. For now just skip over that object and try the next one. Also emit a warning if the object names don't match.
2017-01-14	Write 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.
