Add sancov plugin2016-06-07T20:57:10ZEmese Revfyre.emese@gmail.com2016-05-23T22:11:37Zurn:sha1:543c37cb165049c3be24a0d4733e67caa2b33eef
The sancov gcc plugin inserts a __sanitizer_cov_trace_pc() call
at the start of basic blocks.
This plugin is a helper plugin for the kcov feature. It supports
all gcc versions with plugin support (from gcc-4.5 on).
It is based on the gcc commit "Add fuzzing coverage support" by Dmitry Vyukov
(https://gcc.gnu.org/viewcvs/gcc?limit_changes=0&view=revision&revision=231296).
