2024-02-08	Assume C compiler's default standard is `-std=gnu17`	Martin Nowack
	Newer compilers use `-std=gnu17` as the default when compiling C code. Fix all the test cases that violate this behaviour or explicitly request older standards `-std=c89` where necessary.
2023-03-23	Remove model_version from the POSIX runtime, as we have never used it.	Cristian Cadar

2022-06-15	Spelling Fixes	m-davis

2022-05-06	Updated tests to use ktest-randgen instead of gen-random-bout	Cristian Cadar

2022-05-06	Updated tests to use ktest-gen instead of gen-bout	Cristian Cadar

2021-11-20	Fixed fail with preferCex, removed relation from first argument	Taras Bereznyak

2020-10-06	Added support for klee_open_merge and klee_close_merge in replay, together ↵	Cristian Cadar
	with a test case.
2020-09-17	Add test for klee-zesti	Timotej Kapus

2020-08-07	New intrinsic: klee_is_replay	Alastair Reid
	This instrinsic detects whether the program is being executed symbolically or concretely (i.e., using the libkleeRuntest library). The intended usage (illustrated in the test program) is to allow the test program to display the input values by invoking any libraries it wants to. This is especially valuable if you are constructing complex, structured values and for languages like Rust (or C++) that have rich libraries and print libraries. For example, you might pick a symbolic value N with the assumption "0 <= N < 10" and then pick N symbolic values and write them to an array. The resulting ktest file is a bit hard to understand compared with the output of the standard print function in Rust/C++.
2019-08-14	Rewrote the checks in GenRandomBout.c to remove dependency on bash and use ↵	Cristian Cadar
	FileCheck instead (FreeBSD tests on Travis CI fail otherwise)
2019-08-14	Moved Gen*Bout.c tests outside the test/Runtime/POSIX directory, as they ↵	Cristian Cadar
	don't need POSIX support to run.
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.
