* 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

* [sanitizer-coverage/libFuzzer] instrument comparisons with ↵Kostya Serebryany2016-08-181-0/+2
| | | | | | __sanitizer_cov_trace_cmp[1248] instead of __sanitizer_cov_trace_cmp, don't pass the comparison type to save a bit performance. Use these new callbacks in libFuzzer llvm-svn: 279027
