/*
* "Optimize" a list of dependencies as spit out by gcc -MD
* for the kernel build
* ===========================================================================
*
* Author Kai Germaschewski
* Copyright 2002 by Kai Germaschewski <kai.germaschewski@gmx.de>
*
* This software may be used and distributed according to the terms
* of the GNU General Public License, incorporated herein by reference.
*
*
* Introduction:
*
* gcc produces a very nice and correct list of dependencies which
* tells make when to remake a file.
*
* To use this list as-is however has the drawback that virtually
* every file in the kernel includes autoconf.h.
*
* If the user re-runs make *config, autoconf.h will be
* regenerated. make notices that and will rebuild every file which
* includes autoconf.h, i.e. basically all files. This is extremely
* annoying if the user just changed CONFIG_HIS_DRIVER from n to m.
*
* So we play the same trick that "mkdep" played before. We replace
* the dependency on autoconf.h by a dependency on every config
* option which is mentioned in any of the listed prequisites.
*
* kconfig populates a tree in include/config/ with an empty file
* for each config symbol and when the configuration is updated
* the files representing changed config options are touched
* which then let make pick up the changes and the files that use
* the config symbols are rebuilt.
*
* So if the user changes his CONFIG_HIS_DRIVER option, only the objects
* which depend on "include/linux/config/his/driver.h" will be rebuilt,
* so most likely only his driver ;-)
*
* The idea above dates, by the way, back to Michael E Chastain, AFAIK.
*
* So to get dependencies right, there are two issues:
* o if any of the files the compiler read changed, we need to rebuild
* o if the command line given to the compile the file changed, we
* better rebuild as well.
*
* The former is handled by using the -MD output, the later by saving
* the command line used to compile the old object and comparing it
* to the one we would now use.
*
* Again, also this idea is pretty old and has been discussed on
* kbuild-devel a long time ago. I don't have a sensibly working
* internet connection right now, so I rather don't mention names
* without double checking.
*
* This code here has been based partially based on mkdep.c, which
* says the following about its history:
*
* Copyright abandoned, Michael Chastain, <mailto:mec@shout.net>.
* This is a C version of syncdep.pl by Werner Almesberger.
*
*
* It is invoked as
*
* fixdep <depfile> <target> <cmdline>
*
* and will read the dependency file <depfile>
*
* The transformed dependency snipped is written to stdout.
*
* It first generates a line
*
* cmd_<target> = <cmdline>
*
* and then basically copies the .<target>.d file to stdout, in the
* process filtering out the dependency on autoconf.h and adding
* dependencies on include/config/my/option.h for every
* CONFIG_MY_OPTION encountered in any of the prequisites.
*
* It will also filter out all the dependencies on *.ver. We need
* to make sure that the generated version checksum are globally up
* to date before even starting the recursive build, so it's too late
* at this point anyway.
*
* The algorithm to grep for "CONFIG_..." is bit unusual, but should
* be fast ;-) We don't even try to really parse the header files, but
* merely grep, i.e. if CONFIG_FOO is mentioned in a comment, it will
* be picked up as well. It's not a problem with respect to
* correctness, since that can only give too many dependencies, thus
* we cannot miss a rebuild. Since people tend to not mention totally
* unrelated CONFIG_ options all over the place, it's not an
* efficiency problem either.
*
* (Note: it'd be easy to port over the complete mkdep state machine,
* but I don't think the added complexity is worth it)
*/
/*
* Note 2: if somebody writes HELLO_CONFIG_BOOM in a file, it will depend onto
* CONFIG_BOOM. This could seem a bug (not too hard to fix), but please do not
* fix it! Some UserModeLinux files (look at arch/um/) call CONFIG_BOOM as
* UML_CONFIG_BOOM, to avoid conflicts with /usr/include/linux/autoconf.h,
* through arch/um/include/uml-config.h; this fixdep "bug" makes sure that
* those files will have correct dependencies.
