* Port libFuzzer tests to LIT. Do not require two-stage build for check-fuzzer.George Karpenkov2017-08-0471-429/+333
| | | | | | | | | | | | | | | | | | | | | This revision ports all libFuzzer tests apart from the unittest to LIT. The advantages of doing so include: - Tests being self-contained - Much easier debugging of a single test - No need for using a two-stage compilation The unit-test is still compiled using CMake, but it does not need a freshly built compiler. NOTE: The previous two-stage bot configuration will NOT work, as in the second stage build LLVM_USE_SANITIZER is set, which disables ASAN from being built. Thus bots will be reconfigured in the next few commits. Differential Revision: https://reviews.llvm.org/D36295 llvm-svn: 310075

* [libFuzzer tests] Use substring comparison in libFuzzer testsGeorge Karpenkov2017-08-021-1/+1
| | | | | | | | | LIT launches executables with absolute, and not relative, path. strncmp would try to do exact comparison and fail. Differential Revision: https://reviews.llvm.org/D36242 llvm-svn: 309889

* Generate error reports when a fuzz target exits.Matt Morehouse2017-07-2018-20/+36
| | | | | | | | | | | | | | | | | | | | | | Summary: Implements https://github.com/google/sanitizers/issues/835. Flush stdout before exiting in test cases. Since the atexit hook is used for exit reports, pending prints to stdout can be lost if they aren't flushed before calling exit(). Expect tests to have non-zero exit code if exit() is called.

* Fix fuzzer-flags.test on WindowsReid Kleckner2017-07-192-3/+1
| | | | | | | | | | | The optional external function callbacks have to be exported in order for them to be called. The test was failing because libFuzzer wasn't calling LLVMFuzzerInitialize. We can reconsider if this is the best way to mark these optional callbacks exported later. llvm-svn: 308548

* [libFuzzer] Allow non-fuzzer args after -ignore_remaining_args=1Justin Bogner2017-07-143-3/+44
| | | | | | | | | | | With this change, libFuzzer will ignore any arguments after a sigil argument, but it will preserve these arguments at the end of the command line when launching subprocesses. Using this, its possible to handle positional and single-dash arguments to the program under test by discarding everything up to -ignore_remaining_args=1 in LLVMFuzzerInitialize. llvm-svn: 308069
