Pull kbuild updates from Michal Marek:
- GCC plugin support by Emese Revfy from grsecurity, with a fixup from
Kees Cook. The plugins are meant to be used for static analysis of
the kernel code. Two plugins are provided already.
- reduction of the gcc commandline by Arnd Bergmann.
- IS_ENABLED / IS_REACHABLE macro enhancements by Masahiro Yamada
- bin2c fix by Michael Tautschnig
- setlocalversion fix by Wolfram Sang
* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
gcc-plugins: disable under COMPILE_TEST
kbuild: Abort build on bad stack protector flag
scripts: Fix size mismatch of kexec_purgatory_size
kbuild: make samples depend on headers_install
Kbuild: don't add obj tree in additional includes
Kbuild: arch: look for generated headers in obtree
Kbuild: always prefix objtree in LINUXINCLUDE
Kbuild: avoid duplicate include path
Kbuild: don't add ../../ to include path
vmlinux.lds.h: replace config_enabled() with IS_ENABLED()
kconfig.h: allow to use IS_{ENABLE,REACHABLE} in macro expansion
kconfig.h: use already defined macros for IS_REACHABLE() define
export.h: use __is_defined() to check if __KSYM_* is defined
kconfig.h: use __is_defined() to check if MODULE is defined
kbuild: setlocalversion: print error to STDERR

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. |
