  • c79624c1a   kbuild: Fix packaging targets with relative $(srctree) ... Browse Code »

    All other users of Makefile.build set $(obj) to the name of the
    subdirectory to build. Do the same for the packaging targets, otherwise
    the build fails if $(srctree) is a relative directory:

    $ make O=build tar-pkg
    make[1]: Entering directory `/home/mmarek/linux-2.6/build'
    CHK include/config/kernel.release
    ../scripts/Makefile.build:44: ../../scripts/package/Makefile: No such file or directory
    make[2]: *** No rule to make target `../../scripts/package/Makefile'. Stop.

    With commit 9da0763b (kbuild: Use relative path when building in a
    subdir of the source tree), the compiler messages include relative
    paths. These are however relative to the build directory, not the
    directory where make was started. Print the "Entering directory ..."
    message once, so that IDEs/editors can find the source files.

    On architectures that setup CROSS_COMPILE in their arch/*/Makefile
    (arc, blackfin, m68k, mips, parisc, score, sh, tile, unicore32, xtensa),
    cc-option and cc-disable-warning may check against the wrong compiler,
    causing errors like

    cc1: error: unrecognized command line option "-Wno-maybe-uninitialized"

    if the host gcc supports a compiler option, while the cross compiler
    doesn't support that option.

    Move all logic using cc-option or cc-disable-warning below the inclusion
    of the arch's Makefile to fix this.

    Introduced by
    - commit e74fc973b6e531fef1fce8b101ffff05ecfb774c ("Turn off
    -Wmaybe-uninitialized when building with -Os"),
    - commit 61163efae02040f66a95c8ed17f4407951ba58fa ("kbuild: LLVMLinux:
    Add Kbuild support for building kernel with Clang").

    As -Wno-maybe-uninitialized requires a quite recent gcc (gcc 4.6.3 on
    Ubuntu 12.04 LTS doesn't support it), this only showed up recently (gcc
    4.8.2 on Ubuntu 14.04 LTS does support it).

    When doing make O=, use '..' to refer to the source tree. This
    allows for more readable compiler messages, and, more importantly, it
    sets the VPATH to '..', so filenames in WARN_ON() etc. will be shorter.

    When not using O=, $(srctree) refers to the same directory as
    $(objtree), so we can set it to '.' as well. This makes the default
    include path more compact and results in more readable messages from the
    compiler. The only case where we need the absolute path is when creating
    the 'source' symlink in /lib/modules.

    The main Makefile sets its working directory to the object tree and
    never changes it again. Therefore, we can use '.' instead of the
    absolute path. The only case where we need the absolute path is when
    creating the 'build' symlink in /lib/modules.

    Kbuild is supposed to support mixed targets. (%config and build targets)

    But "make all" did nothing if it was run with configuration targets.
    For example,

    $ LANG=C make defconfig all
    HOSTCC scripts/basic/fixdep
    HOSTCC scripts/kconfig/conf.o
    SHIPPED scripts/kconfig/zconf.tab.c
    SHIPPED scripts/kconfig/zconf.lex.c
    SHIPPED scripts/kconfig/zconf.hash.c
    HOSTCC scripts/kconfig/zconf.tab.o
    HOSTLD scripts/kconfig/conf
    *** Default configuration is based on 'x86_64_defconfig'
    #
    # configuration written to .config
    #
    make: Nothing to be done for `all'.

    This commits allows "make %config all" and makes sure
    mixed targets are built one by one in the given order.

  • a86fe3537   kbuild: move extra gcc checks to scripts/Makefile.extrawarn ... Browse Code »

    W=... provides extra gcc checks.

    Having such code in scripts/Makefile.build results in the same flags
    being added to KBUILD_CFLAGS multiple times becuase
    scripts/Makefile.build is invoked every time Kbuild descends into
    the subdirectories.

    Since the top Makefile is already too cluttered, this commit moves
    all of extra gcc check stuff to a new file scripts/Makefile.extrawarn,
    which is included from the top Makefile.

    Add support to toplevel Makefile for compiling with clang, both for
    HOSTCC and CC. Use cc-option to prevent gcc option from breaking clang, and
    from clang options from breaking gcc.

    Clang 3.4 semantics are the same as gcc semantics for unsupported flags. For
    unsupported warnings clang 3.4 returns true but shows a warning and gcc shows
    a warning and returns false.

    objdiff is useful when doing large code cleanups. For example, when
    removing checkpatch warnings and errors from new drivers in the staging
    tree.

    objdiff can be used in conjunction with a git rebase to confirm that
    each commit made no changes to the resulting object code. It has the
    same return values as diff(1).

    This was written specifically to support adding the skein and threefish
    cryto drivers to the staging tree. I needed a programmatic way to
    confirm that commits changing >90% of the lines didn't inadvertently
    change the code.

    Temporary files (objdump output) are stored in

    /path/to/linux/.tmp_objdiff

    'make mrproper' will remove this directory.
