  • 5e8d780d7   kbuild: fix ia64 breakage after introducing make -rR ... Browse Code »

    kbuild used $¤(*F to get filename of target without extension.
    This was used in several places all over kbuild, but introducing
    make -rR broke his for all cases where we specified full path to
    target/prerequsite. It is assumed that make -rR disables old style
    suffix-rules which is why is suddenly failed.

    ia64 was impacted by this change because several div* routines in
    arch/ia64/lib are build using explicit paths and then kbuild failed.

    Thanks to David Mosberger-Tang for an explanation
    what was the root-cause and for testing on ia64.

    This patch also fixes two uses of $(*F) in arch/um

    This reverts commit e5c44fd88c146755da6941d047de4d97651404a9.

    Thanks to Daniel Ritz and Michal Piotrowski for noticing the problem.

    Daniel says:

    "[The] reason is a recent change that made modules always shows as
    module.mod. it breaks modprobe and probably many scripts..besides
    lsmod looking horrible

    stuff like this in modprobe.conf:
    install pcmcia_core /sbin/modprobe --ignore-install pcmcia_core; /sbin/modprobe pcmcia
    makes modprobe fork/exec endlessly calling itself...until oom
    interrupts it"

  • e5c44fd88   kbuild: fix make -rR breakage ... Browse Code »

    make failed to supply the filename when using make -rR and using $(*F)
    to get target filename without extension.
    This bug was not reproduceable in small scale but using:
    $(basename $(notdir $@)) fixes it with same functionality.

  • d9df92e22   kbuild: properly pass options to hostcc when doing make O=.. ... Browse Code »

    This fix a longstanding bug where proper options was not
    passed to hostcc in case of a make O=.. build.
    This bug showed up in (not yet merged) klibc, and is not known
    to have any counterpart in-kernel.
    Fixed by moving the flags macro to Kbuild.include so it can be used
    by both Makefile.lib and Makefile.host.

  • 4f1933620   kbuild: change kbuild to not rely on incorrect GNU make behavior ... Browse Code »

    The kbuild system takes advantage of an incorrect behavior in GNU make.
    Once this behavior is fixed, all files in the kernel rebuild every time,
    even if nothing has changed. This patch ensures kbuild works with both
    the incorrect and correct behaviors of GNU make.

    For more details on the incorrect behavior, see:

    http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html

    Changes in this patch:
    - Keep all targets that are to be marked .PHONY in a variable, PHONY.
    - Add .PHONY: $(PHONY) to mark them properly.
    - Remove any $(PHONY) files from the $? list when determining whether
    targets are up-to-date or not.

  • 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.

  • 20a468b51   kbuild: make cc-version available in kbuild files ... Browse Code »

    Move $(CC) support functions to Kbuild.include so they are available
    in the kbuild files.
    In addition the following was done:
    o as-option documented in Documentation/kbuild/makefiles.txt
    o Moved documentation to new section to match
    new scope of functions
    o added cc-ifversion used to conditionally select a text string
    dependent on actual $(CC) version
    o documented cc-ifversion
    o change so Kbuild.include is read before the kbuild file

    $(foo) is an absolute path.

  • 8ec4b4ff1   kbuild: introduce Kbuild.include ... Browse Code »

    Kbuild.include is a placeholder for definitions originally present in
    both the top-level Makefile and scripts/Makefile.build.
    There were a slight difference in the filechk definition, so the most videly
    used version was kept and usr/Makefile was adopted for this syntax.
