Kostya Serebryany	dfbe59b03d	[libFuzzer] add InsertRepeatedBytes and EraseBytes. 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	2016-08-15 17:48:28 +00:00
Dan Liew	02432480c7	[LibFuzzer] Move tests in ``fuzzer-traces.test`` that require hooks to their own test. The tests in ``fuzzer-traces-hooks.test`` only work on Linux because calls to hooks (e.g. ``__sanitizer_weak_hook_memcmp()``) from inside the sanitizer runtime are only implemented on Linux. Therefore these tests are set to only run on Linux. Differential Revision: http://reviews.llvm.org/D21253 llvm-svn: 272600	2016-06-14 00:11:34 +00:00

Kostya Serebryany	ae5b9567bc	[libFuzzer] do mutations based on memcmp/strcmp interceptors under a separate flag (-use_memcmp, default=1) llvm-svn: 257873	2016-01-15 06:24:05 +00:00
Kostya Serebryany	4b35874b2a	[libFuzzer] suggest a dictionary to the user of some of the trace-based dictionary entries were successful llvm-svn: 257736	2016-01-14 02:36:44 +00:00
Kostya Serebryany	b65805a939	[libFuzzer] change the way trace-based mutations are applied. Instead of a custom code just rely on the automatically created dictionary llvm-svn: 257248	2016-01-09 03:08:58 +00:00
Kostya Serebryany	bf65644c97	[libFuzzer] split the tests to run them in parallel, remove one redundant test llvm-svn: 256085	2015-12-19 03:35:30 +00:00
