Jake Ehrlich 4b23c24bc8 [libFuzzer] Always print DSO map on Fuchsia libFuzzer launch 
Fuchsia doesn't have /proc/id/maps, so it relies on the kernel logging system
to provide the DSO map to be able to symbolize in the context of ASLR. The DSO
map is logged automatically on Fuchsia when encountering a crash or writing to
the sanitizer log for the first time in a process. There are several cases
where libFuzzer doesn't encounter a crash, e.g. on timeouts, OOMs, and when
configured to print new PCs as they become covered, to name a few. Therefore,
this change always writes to the sanitizer log on startup to ensure the DSO map
is available in the log.

afl Summary: 2019-04-18 18:49:11 +00:00
dataflow [libFuzzer] split DataFlow.cpp into two .cpp files, one of which can be compiled w/o dfsan to speed things up (~25% speedup) 2019-06-21 01:39:35 +00:00
scripts [libFuzzer] remove the data-flow-trace (DFT) python scripts; their functionality is now part of libFuzzer proper; also write functions.txt to the disk only if this file doesn't exist yet 2019-05-23 01:03:42 +00:00
