* [libFuzzer] don't require seed in fuzzer::Mutate, instead use the global ↵Kostya Serebryany2016-02-131-0/+5
| | | | | | Fuzzer object for fuzzer::Mutate. This makes custom mutators fast llvm-svn: 260810

| | | | llvm-svn: 260794
* [libFuzzer] don't write the test unit when a leak is detected (since we ↵Kostya Serebryany2016-02-041-0/+1
| | | | | | don't know which unit causes the leak) llvm-svn: 259731

* Use std::piecewise_constant_distribution instead of ad-hoc binary search.Ivan Krasin2016-01-221-35/+45
| | | | | | | | | | | | | | | Summary: Fix the issue with the most recently discovered unit receiving much less attention. Note: this is the second attempt (prev: r258473). Now, libc++ build is fixed. Reviewers: aizatsky, kcc Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D16487 llvm-svn: 258571

* Use std::piecewise_constant_distribution instead of ad-hoc binary search.Ivan Krasin2016-01-221-15/+18
| | | | | | | | | | | | | | | | | | Summary: Fix the issue with the most recently discovered unit receiving much less attention. Note: I had to change the seed for one test to make it pass. Alternatively, the number of runs could be increased. I believe that the average time of 'foo' discovery is not increased, just seed=1 was particularly convenient for the previous PRNG scheme used.

* [libFuzzer] make sure we find buffer overflow in the input buffer. ↵Kostya Serebryany2016-01-131-5/+8
| | | | | | Previously, re-using the same vector object was hiding buffer overflows (unless we used annotated vector) llvm-svn: 257701
