  • 6a5be57f0   fixdep: fix extraneous dependencies ... Browse Code »

    The introduction of include/linux/kconfig.h created 3 extraneous
    dependencies:
    include/config/.h
    include/config/h.h
    include/config/foo.h

    Fix this by excluding kconfig.h from fixdep calculations.

    fixdep: Do not record dependency on the source file itself

    changed the format of the *.cmd files without realizing that it is also
    used by modpost. Put the path to the source file to the file back, in a
    special variable, so that modpost sees all source files when calculating
    srcversion for modules.

  • b7bd18217   fixdep: Do not record dependency on the source file itself ... Browse Code »

    The dependency is already expressed by the Makefiles, storing it in the
    .cmd file breaks build if a .c file is replaced by .S or vice versa,
    because the .cmd file contains

    foo/bar.o: foo/bar.c ...

    foo/bar.c ... :

    so the foo/bar.c -> foo/bar.o rule triggers even if there is no
    foo/bar.c anymore.

  • 8af27e1dc   fixdep: use hash table instead of a single array ... Browse Code »

    I noticed fixdep uses ~2% of cpu time in kernel build, in function
    use_config()

    fixdep spends a lot of cpu cycles in linear searches in its internal
    string array. With about 400 stored strings per dep file, this begins to
    be noticeable.

    Convert fixdep to use a hash table.

    build scripts: fixdep blows segfault on string CONFIG_MODULE seen

    The string "CONFIG_MODULE" appearing anywhere in a source file causes
    fixdep to segfault. This string appeared in the wild in the current
    mISDN sources (I think they meant CONFIG_MODULES). But it shouldn't
    segfault (esp as CONFIG_MODULE appeared in a quoted string).

  • c21b1e4d9   [PATCH] kbuild: fix dependency generation ... Browse Code »

    Commit 2e3646e51b2d6415549b310655df63e7e0d7a080 changed the way the
    split config tree is built, but failed to also adjust fixdep accordingly
    - if changing a config option from or to m, files referencing the
    respective CONFIG_..._MODULE (but not the corresponding CONFIG_...)
    didn't get rebuilt.

    The problem is that trisate symbol are represent with three different
    symbols:
    SYMBOL=n => no symbol defined
    SYMBOL=y => CONFIG_SYMBOL defined to '1'
    SYMBOL=m => CONFIG_SYMBOL_MODULE defined to '1'

    But conf_split_config do not distingush between the =y and =m case, so
    only the =y case is honoured.

    This is fixed in fixdep so when a CONFIG symbol with _MODULE is found we
    skip that part and only look for the CONFIG_SYMBOL version.

  • 6176aa9ae   kbuild: consolidate command line escaping ... Browse Code »

    While the recent change to also escape # symbols when storing C-file
    compilation command lines was helpful, it should be in effect for all
    command lines, as much as the dollar escaping should be in effect for
    C-source compilation commands. Additionally, for better readability and
    maintenance, consolidating all the escaping (single quotes, dollars,
    and now sharps) was also desirable.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
