Michael Zolotukhin de19ed1eb1 [LoopUnroll] Avoid unnecessary DT recomputation. ... Summary: When we completely unroll a loop, it's pretty easy to update DT in-place and thus avoid rebuilding it. DT recalculation is one of the most time-consuming tasks in loop-unroll, so avoiding it at least in case of full unroll should be beneficial. On some extreme (but still real-world) tests this patch improves compile time by ~2x.

Instrumentation	[sanitizer-coverage] implement -fsanitize-coverage=trace-pc. This is similar to trace-bb, but has a different API. We already use the equivalent flag in GCC for Linux kernel fuzzing. We may be able to use this flag with AFL too	2016-02-17 21:34:43 +00:00
