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 linux/autoconf.h by a dependency on every config + * option which is mentioned in any of the listed prequisites. + * + * To be exact, split-include populates a tree in include/config/, + * e.g. include/config/his/driver.h, which contains the #define/#undef + * for the CONFIG_HIS_DRIVER option. + * + * 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, . + * This is a C version of syncdep.pl by Werner Almesberger. + * + * + * It is invoked as + * + * fixdep + * + * and will read the dependency file + * + * The transformed dependency snipped is written to stdout. + * + * It first generates a line + * + * cmd_ = + * + * and then basically copies the ..d file to stdout, in the + * process filtering out the dependency on linux/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.
