GCC plugin infrastructure
This patch allows to build the whole kernel with GCC plugins. It was ported from
grsecurity/PaX. The infrastructure supports building out-of-tree modules and
building in a separate directory. Cross-compilation is supported too.
Currently the x86, arm, arm64 and uml architectures enable plugins.
The directory of the gcc plugins is scripts/gcc-plugins. You can use a file or a directory
there. The plugins compile with these options:
* -fno-rtti: gcc is compiled with this option so the plugins must use it too
* -fno-exceptions: this is inherited from gcc too
* -fasynchronous-unwind-tables: this is inherited from gcc too
* -ggdb: it is useful for debugging a plugin (better backtrace on internal
errors)
* -Wno-narrowing: to suppress warnings from gcc headers (ipa-utils.h)
* -Wno-unused-variable: to suppress warnings from gcc headers (gcc_version
variable, plugin-version.h)
The infrastructure introduces a new Makefile target called gcc-plugins. It
supports all gcc versions from 4.5 to 6.0. The scripts/gcc-plugin.sh script
chooses the proper host compiler (gcc-4.7 can be built by either gcc or g++).
This script also checks the availability of the included headers in
scripts/gcc-plugins/gcc-common.h.
The gcc-common.h header contains frequently included headers for GCC plugins
and it has a compatibility layer for the supported gcc versions.
The gcc-generate-*-pass.h headers automatically generate the registration
structures for GIMPLE, SIMPLE_IPA, IPA and RTL passes.
Note that 'make clean' keeps the *.so files (only the distclean or mrproper
targets clean all) because they are needed for out-of-tree modules.
Based on work created by the PaX Team.

GCC plugin infrastructure
|
||||
=========================
|
||||
|
||||
|
||||
1. Introduction
|
||||
===============
|
||||
|
||||
GCC plugins are loadable modules that provide extra features to the
|
||||
compiler [1]. They are useful for runtime instrumentation and static analysis.
|
||||
We can analyse, change and add further code during compilation via
|
||||
callbacks [2], GIMPLE [3], IPA [4] and RTL passes [5].
|
||||
|
||||
The GCC plugin infrastructure of the kernel supports all gcc versions from
|
||||
4.5 to 6.0, building out-of-tree modules, cross-compilation and building in a
|
||||
separate directory.
|
||||
Plugin source files have to be compilable by both a C and a C++ compiler as well
|
||||
because gcc versions 4.5 and 4.6 are compiled by a C compiler,
|
||||
gcc-4.7 can be compiled by a C or a C++ compiler,
|
||||
and versions 4.8+ can only be compiled by a C++ compiler.
|
||||
|
||||
Currently the GCC plugin infrastructure supports only the x86, arm and arm64
|
||||
architectures.
|
||||
|
||||
This infrastructure was ported from grsecurity [6] and PaX [7].

2. Files
|
||||
========
|
||||
|
||||
$(src)/scripts/gcc-plugins
|
||||
This is the directory of the GCC plugins.
|
||||
|
||||
$(src)/scripts/gcc-plugins/gcc-common.h
|
||||
This is a compatibility header for GCC plugins.
|
||||
It should be always included instead of individual gcc headers.
|
||||
|
||||
$(src)/scripts/gcc-plugin.sh
|
||||
This script checks the availability of the included headers in
|
||||
gcc-common.h and chooses the proper host compiler to build the plugins
|
||||
(gcc-4.7 can be built by either gcc or g++).
|
||||
|
||||
$(src)/scripts/gcc-plugins/gcc-generate-gimple-pass.h
|
||||
$(src)/scripts/gcc-plugins/gcc-generate-ipa-pass.h
|
||||
$(src)/scripts/gcc-plugins/gcc-generate-simple_ipa-pass.h
|
||||
$(src)/scripts/gcc-plugins/gcc-generate-rtl-pass.h
|
||||
These headers automatically generate the registration structures for
|
||||
GIMPLE, SIMPLE_IPA, IPA and RTL passes. They support all gcc versions
|
||||
from 4.5 to 6.0.
|
||||
They should be preferred to creating the structures by hand.
|
||||
|
||||
|
||||
3. Usage
|
||||
========
|
||||
|
||||
You must install the gcc plugin headers for your gcc version,
|
||||
e.g., on Ubuntu for gcc-4.9:
|
||||
|
||||
apt-get install gcc-4.9-plugin-dev
|
||||
|
||||
Enable a GCC plugin based feature in the kernel config:
|
||||
|
||||
CONFIG_GCC_PLUGIN_CYC_COMPLEXITY = y
|
||||
|
||||
To compile only the plugin(s):
|
||||
|
||||
make gcc-plugins
|
||||
|
||||
or just run the kernel make and compile the whole kernel with
|
||||
the cyclomatic complexity GCC plugin.
|
||||
|
||||
|
||||
4. How to add a new GCC plugin
|
||||
==============================
|
||||
|
||||
The GCC plugins are in $(src)/scripts/gcc-plugins/. You can use a file or a directory
|
||||
here. It must be added to $(src)/scripts/gcc-plugins/Makefile,
|
||||
$(src)/scripts/Makefile.gcc-plugins and $(src)/arch/Kconfig.
|
||||
See the cyc_complexity_plugin.c (CONFIG_GCC_PLUGIN_CYC_COMPLEXITY) GCC plugin.
