# Clean up QEMU #include lines by ensuring that qemu/osdep.h
# is the first include listed in .c files, and no headers provided
# by osdep.h itself are redundantly included in either .c or .h files.
#
# Copyright (c) 2015 Linaro Limited

# Authors:
# Peter Maydell <peter.maydell@linaro.org>
#
# This work is licensed under the terms of the GNU GPL, version 2
# or (at your option) any later version. See the COPYING file in
# the top-level directory.
# Usage:
# clean-includes [--git subjectprefix] file ...
# or
# clean-includes [--git subjectprefix] --all
#
# If the --git subjectprefix option is given, then after making
# the changes to the files this script will create a git commit
# with the subject line "subjectprefix: Clean up includes"
# and a boilerplate commit message.
#
# Using --all will cause clean-includes to run on the whole source
# tree (excluding certain directories which are known not to need
# handling).
# This script requires Coccinelle to be installed.
# .c files will have the osdep.h included added, and redundant
# includes removed.
# .h files will have redundant includes (including includes of osdep.h)
# removed.
# Other files (including C++ and ObjectiveC) can't be handled by this script.
# The following one-liner may be handy for finding files to run this on.
# However some caution is required regarding files that might be part
# of the guest agent or standalone tests.
# for i in `git ls-tree --name-only HEAD` ; do test -f $i && \
