* 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
* Revert r258473 as it's breaking the build with libc++Ivan Krasin2016-01-221-18/+15

* 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
