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
2+
=========================
3+
4+
5+
1. Introduction
6+
===============
7+
8+
GCC plugins are loadable modules that provide extra features to the
9+
compiler [1]. They are useful for runtime instrumentation and static analysis.
10+
We can analyse, change and add further code during compilation via
11+
callbacks [2], GIMPLE [3], IPA [4] and RTL passes [5].
12+
13+
The GCC plugin infrastructure of the kernel supports all gcc versions from
14+
4.5 to 6.0, building out-of-tree modules, cross-compilation and building in a
15+
separate directory.
16+
Plugin source files have to be compilable by both a C and a C++ compiler as well
17+
because gcc versions 4.5 and 4.6 are compiled by a C compiler,
18+
gcc-4.7 can be compiled by a C or a C++ compiler,
19+
and versions 4.8+ can only be compiled by a C++ compiler.
20+
21+
Currently the GCC plugin infrastructure supports only the x86, arm and arm64
22+
architectures.
23+
24+
This infrastructure was ported from grsecurity [6] and PaX [7].

2. Files
37+
========
38+
39+
$(src)/scripts/gcc-plugins
40+
This is the directory of the GCC plugins.
41+
42+
$(src)/scripts/gcc-plugins/gcc-common.h
43+
This is a compatibility header for GCC plugins.
44+
It should be always included instead of individual gcc headers.
45+
46+
$(src)/scripts/gcc-plugin.sh
47+
This script checks the availability of the included headers in
48+
gcc-common.h and chooses the proper host compiler to build the plugins
49+
(gcc-4.7 can be built by either gcc or g++).
50+
51+
$(src)/scripts/gcc-plugins/gcc-generate-gimple-pass.h
52+
$(src)/scripts/gcc-plugins/gcc-generate-ipa-pass.h
53+
$(src)/scripts/gcc-plugins/gcc-generate-simple_ipa-pass.h
54+
$(src)/scripts/gcc-plugins/gcc-generate-rtl-pass.h
55+
These headers automatically generate the registration structures for
56+
GIMPLE, SIMPLE_IPA, IPA and RTL passes. They support all gcc versions
57+
from 4.5 to 6.0.
58+
They should be preferred to creating the structures by hand.
59+
60+
61+
3. Usage
62+
========
63+
64+
You must install the gcc plugin headers for your gcc version,
65+
e.g., on Ubuntu for gcc-4.9:
66+
67+
apt-get install gcc-4.9-plugin-dev
68+
69+
Enable a GCC plugin based feature in the kernel config:
70+
71+
CONFIG_GCC_PLUGIN_CYC_COMPLEXITY = y
72+
73+
To compile only the plugin(s):
74+
75+
make gcc-plugins
76+
77+
or just run the kernel make and compile the whole kernel with
78+
the cyclomatic complexity GCC plugin.
79+
80+
81+
4. How to add a new GCC plugin
82+
==============================
83+
84+
The GCC plugins are in $(src)/scripts/gcc-plugins/. You can use a file or a directory
85+
here. It must be added to $(src)/scripts/gcc-plugins/Makefile,
86+
$(src)/scripts/Makefile.gcc-plugins and $(src)/arch/Kconfig.
87+
See the cyc_complexity_plugin.c (CONFIG_GCC_PLUGIN_CYC_COMPLEXITY) GCC plugin.

* Usage:
7+

8+
* 1. before inclusion define PASS_NAME
9+
* 2. before inclusion define NO_* for unimplemented callbacks
10+
* NO_GATE
11+
* NO_EXECUTE
12+
* 3. before inclusion define PROPERTIES_* and TODO_FLAGS_* to override
13+
* the default 0 values
14+
* 4. for convenience, all the above will be undefined after inclusion!
15+
* 5. the only exported name is make_PASS_NAME_pass() to register with gcc
