# SPDX-License-Identifier: GPL-2.0-onlyconfig HAVE_GCC_PLUGINS	bool	help	  An arch should select this symbol if it supports building with	  GCC plugins. menuconfig GCC_PLUGINS	bool "GCC plugins"	depends on HAVE_GCC_PLUGINS	depends on CC_IS_GCC	depends on $(success,test -e $(shell,$(CC) -print-file-name=plugin)/include/plugin-version.h)	default y	help	  GCC plugins are loadable modules that provide extra features to the	  compiler. They are useful for runtime instrumentation and static analysis. 	  See Documentation/kbuild/gcc-plugins.rst for details. if GCC_PLUGINS config GCC_PLUGIN_SANCOV	bool	# Plugin can be removed once the kernel only supports GCC 6+	depends on !CC_HAS_SANCOV_TRACE_PC	help	  This plugin inserts a __sanitizer_cov_trace_pc() call at the start of	  basic blocks. It supports all gcc versions with plugin support (from	  gcc-4.5 on). It is based on the commit "Add fuzzing coverage support"	  by Dmitry Vyukov <dvyukov@google.com>. config GCC_PLUGIN_LATENT_ENTROPY	bool "Generate some entropy during boot and runtime"	help	  By saying Y here the kernel will instrument some kernel code to	  extract some entropy from both original and artificially created	  program state.  This will help especially embedded systems where	  there is little 'natural' source of entropy normally.  The cost	  is some slowdown of the boot process (about 0.5%) and fork and	  irq processing. 	  Note that entropy extracted this way is not cryptographically	  secure! 	  This plugin was ported from grsecurity/PaX.
