From fa4d93a08d5cd4f349c480b194a3e795273b27ed Mon Sep 17 00:00:00 2001 From: Lei Zhang Date: Fri, 25 May 2018 21:47:19 +0000 Subject: Move fuzzers to testing/fuzzers. Move them out of testing/libfuzzer, to make it possible to pull libfuzzer into that directory. Leave testing/libfuzzer/BUILD.gn there for now as a transitional build file.
