Subject: [PATCH v2 0/3] Introduce GCC plugin infrastructure
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 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)
* Removed the unnecessary example plugin
