When SUBARCH is "omap1" or "omap2", plat-omap/ directory must be
indexed. Handle this special case properly.While at it, check if mach- directory exists at all.

The emacs rules were constantly lagging behind the exuberant ones. Use a
single set of rules for both, to make the script easier to maintain.
The language understood by both tools is basic regular expression with
some limitations, which are documented in a comment. To be able to store
the rules in an array and easily iterate over it, the script requires
bash now. In the exuberant case, the change fixes some false matches in
and also some too greedy matches in the arguments
of the DECLARE_*/DEFINE_* macros. In the emacs case, several previously
not working rules are matching now. Tested with these versions of the
tools:Exuberant Ctags 5.8, Copyright (C) 1996-2009 Darren Hiebert

We are not indexing the userspace tools, so the rules only match some

The defconfig files are in predictable locations, so there is no need to

Apparently, ctags applies the rules before deleting comments:
ctags: Warning: include/linux/completion.h:22: null expansion of name pattern "\2"
Work around this particular case by requiring the group to contain at
least one character. Leave the other patters as they are, until a better
solution is found.Signed-off-by: Michal Marek
-
This allows to apply the same patters to both source and header files.
The effect is mostly visible in the case of DECLARE_BITMAP, but there
are small gains all over the place. There is also lots of random changes
in the diff, I believe this is simply because there are still lots of
unexpanded macros in the code and the C and C++ parsers fail and recover
at different points. Also, qconf.h is parsed as C, but that's a
negligible regression.Signed-off-by: Michal Marek

an unmatched '\('. Further, the whole entry did not work, because the
regex needs to match from the beginning of a line, including keywords
like 'static'. Finally, '\w' should not be used, because it
stops at underscores which are often part of variable names in C,

Since commit 22d651dcef536c75f75537290bf3da5038e68b6b ('selftests/powerpc:
Import Anton's memcpy / copy_tofrom_user tests'), some source files in the
tree appear as symlink.
Until commit 8c38a5328af8080bc69a25b3e4e144b03eeea95e ('scripts/tags.sh:
ignore code of user space tools'), those symlinks made cscope report some
warnings:$ make ALLSOURCE_ARCHS=all O=./obj-cscope/ cscope
GEN cscope
cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/copyuser_power7.S
cscope: cannot find

cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/memcpy_power7.S
cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/copyuser_64.SIn order to prevent the same kind of warnings to be triggered by future
addition of symlinks, the best option is to ignore all symlinks when
building the file list to be processed by cscope (and other tools
supported by scripts/tags.sh).Ignoring symlinks won't hide source files from cscope (and others) as the
target of these symlinks already appear somewhere else in the tree, and,
as such, should be processed by cscope (or others).Note that, cscope, when used with -R option to make it find the files to
process by itself, already skip symlinks: it's not expected that cscope
access source files through symlink.On top of commit 8c38a5328af8080bc69a25b3e4e144b03eeea95e ('scripts/tags.sh:
ignore code of user space tools'), scripts/tags.sh output from
"make cscope tags TAGS" is the same with and without this patch: it doesn't
seems to introduce any regression (on Fedora 20).Link: http://lkml.kernel.org/r/1396530975.4361.28.camel@localhost.localdomain

CONFIG_MODVERSIONS=y results in a .mod.c for every compiled file in the
kernel. Issuing a 'make cscope' on a compiled kernel tree results in
the cscope files containing *.mod.c files.[prarit@prarit linux]# make cscope
[prarit@prarit linux]# cat cscope.files | grep mod.c | wc -l
4807These files are not useful for cscope and should be ignored. For example,
# line filename / context / line
