    When the kernel is compiled with an "O=" argument, the object files are
    not in the source tree, but in the build tree.

    This patch fixes O= build by looking for object files in the build tree.

  • 93209d65c   tags: Unify emacs and exuberant rules ... Browse Code »

    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:

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

    'defconfig', which only works on a few architectures nowadays.

    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.

  • d2fb5aeda   tags: Treat header files as C code ... Browse Code »

    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.

    The emacs --regex for DEFINE_HASHTABLE produced a warning because of
    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,
    resulting in wrong entries in the tags file.

  • 9b24a15d8   scripts/tags.sh: ignore symlink'ed source files ... Browse Code »

    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
    file .../tools/testing/selftests/powerpc/copyloops/memcpy_64.S
    cscope: cannot find
    file .../tools/testing/selftests/powerpc/copyloops/memcpy_power7.S
    cscope: cannot find
    file .../tools/testing/selftests/powerpc/copyloops/copyuser_64.S

    In 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).

    Currently, while using ctags to read code, we would get stumbled on

    This patch adds regular expression replacement pattern for such symbols,
    like what have done for the PageXXX flag. It will teach ctags to find
    out the definition for us.

  • ae63b2d7b   scripts/tags.sh: Ignore *.mod.c ... Browse Code »

    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
    4807

    These files are not useful for cscope and should be ignored. For example,

    # line filename / context / line
    1 105 arch/x86/kvm/kvm-intel.mod.c <>
    { 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) },

    4 37 drivers/cpufreq/acpi-cpufreq.mod.c <>
    { 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) },

    Add an export to RCS_FIND_IGNORE so it can be used in scripts/tags.sh
    and add explicitly ignore *.mod.c files.
