15 GCC plugins are loadable modules that provide extra features to the
16 compiler. They are useful for runtime instrumentation and static analysis.

27 This plugin inserts a __sanitizer_cov_trace_pc() call at the start of
28 basic blocks. It supports all gcc versions with plugin support (from
29 gcc-4.5 on). It is based on the commit "Add fuzzing coverage support"
30 by Dmitry Vyukov <dvyukov@google.com>.

33 bool "Generate some entropy during boot and runtime"
35 By saying Y here the kernel will instrument some kernel code to
36 extract some entropy from both original and artificially created
37 program state. This will help especially embedded systems where
38 there is little 'natural' source of entropy normally. The cost
39 is some slowdown of the boot process (about 0.5%) and fork and
