* Moving libFuzzer from LLVM to compiler-rt.George Karpenkov2017-08-211-3/+0
| | | | | | | | | This change only removes libFuzzer tests and CMake machinery, the source copy temporarily remains at the old location. Differential Revision: https://reviews.llvm.org/D36980 llvm-svn: 311405
* [libFuzzer] remove the now redundant 'LLVMFuzzer-' prefix from libFuzzer testsKostya Serebryany2017-08-041-2/+2

* Port libFuzzer tests to LIT. Do not require two-stage build for check-fuzzer.George Karpenkov2017-08-041-1/+2
| | | | | | | | | | | | | | | | | | | | | 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
* Generate error reports when a fuzz target exits.Matt Morehouse2017-07-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

* [libFuzzer] add InsertRepeatedBytes and EraseBytes.Kostya Serebryany2016-08-151-0/+2
New mutation: InsertRepeatedBytes. Updated mutation: EraseByte => EraseBytes. This helps https://github.com/google/sanitizers/issues/710 where libFuzzer was not able to find a known bug. Now it finds it in minutes. Hopefully, the change is general enough to help other targets. llvm-svn: 278687
