This patch set introduce the GCC plugin infrastructure with examples for testing and documentation. GCC plugins are loadable modules that provide extra features to the compiler. They are useful for runtime instrumentation and static analysis. The infrastructure supports all gcc versions from 4.5 to 6.0, building out-of-tree modules and building in a separate directory. Cross-compilation is supported too but currently only the x86 architecture enables plugins. This infrastructure was ported from grsecurity/PaX. It is a CII project supported by the Linux Foundation. Emese Revfy (3): GCC plugin infrastructure Add Cyclomatic complexity plugin Documentations of the GCC plugin infrastructre Changes from v2: * Fixed incorrectly encoded characters * Generate the GIMPLE, IPA, SIMPLE_IPA and RTL pass structures (Suggested-by: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>) * Write plugin related warning messages to stderr instead of stdout (Suggested-by: Kees Cook <keescook@xxxxxxxxxxxx>) * Mention the installation of the gcc plugin headers (Documentation) Changes from v1: * Move the gcc-plugins make target into a separate Makefile because there may be a lot of plugins (Suggested-by: Rasmus Villemoes) * Simplify the dependencies of the plugin related config option (Suggested-by: Kees Cook <keescook@xxxxxxxxxxxx>) * Removed the unnecessary example plugin --- Documentation/dontdiff | 1 + Documentation/gcc-plugins.txt | 80 ++++ Makefile | 41 +- arch/Kconfig | 24 + arch/x86/Kconfig | 1 + init/Makefile | 3 + scripts/Makefile.build | 2 +- scripts/Makefile.clean | 3 +- scripts/Makefile.gcc-plugins | 30 ++ scripts/Makefile.host | 69 ++- scripts/gcc-plugin.sh | 51 ++ scripts/link-vmlinux.sh | 2 +- scripts/package/builddeb | 1 + tools/gcc/Makefile | 19 + tools/gcc/cyc_complexity_plugin.c | 70 +++ tools/gcc/gcc-common.h | 794 +++++++++++++++++++++++++++++++ tools/gcc/gcc-generate-gimple-pass.h | 172 +++++++ tools/gcc/gcc-generate-ipa-pass.h | 286 +++++++++++ tools/gcc/gcc-generate-rtl-pass.h | 172 +++++++ tools/gcc/gcc-generate-simple_ipa-pass.h | 172 +++++++ 20 files changed, 1978 insertions(+), 15 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
