Kostya Serebryany	0800b81a21	[libFuzzer] simplify HandleTrace again, start re-running interesting units and collecting their features. llvm-svn: 282316	2016-09-23 23:51:58 +00:00
Kostya Serebryany	d28099de5d	[libFuzzer] change ValueBitMap to remember the number of bits in it llvm-svn: 282216	2016-09-23 00:22:46 +00:00

Kostya Serebryany	5350178487	[libFuzzer] implement print_pcs with trace-pc-guard. Change the trace-pc-guard heuristic for 8-bit counters to look more like in AFL (not that it's provable better, but the existin test preferes this heuristic) llvm-svn: 281577	2016-09-15 04:36:45 +00:00
