I have to mention the lexer and parser of Kconfig are now built from real .l and .y sources. So, flex and bison are the requirement for building the kernel. Both of them (unlike gperf) have been stable for a long time. This change has been tested several weeks in linux-next, and I did not receive any problem report about this. Summary: - add checks for mistakes, like the choice default is not in choice, help is doubled - document data structure and complex code - fix various memory leaks - change Makefile to build lexer and parser instead of using pre-generated C files - drop 'boolean' keyword, which is equivalent to 'bool' - use default 'yy' prefix and remove unneeded Make variables - fix gettext() check for xconfig - announce that oldnoconfig will be finally removed - make 'Selected by:' and 'Implied by' readable in help and search result - hide silentoldconfig from 'make help' to stop confusing people - fix misc things and cleanups" * tag 'kconfig-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (37 commits) kconfig: Remove silentoldconfig from help and docs; fix kconfig/conf's help kconfig: make "Selected by:" and "Implied by:" readable kconfig: announce removal of oldnoconfig if used kconfig: fix make xconfig when gettext is missing kconfig: Clarify menu and 'if' dependency propagation kconfig: Document 'if' flattening logic kconfig: Clarify choice dependency propagation kconfig: Document SYMBOL_OPTIONAL logic kbuild: remove unnecessary LEX_PREFIX and YACC_PREFIX kconfig: use default 'yy' prefix for lexer and parser kconfig: make conf_unsaved a local variable of conf_read() kconfig: make xfgets() really static kconfig: make input_mode static kconfig: Warn if there is more than one help text kconfig: drop 'boolean' keyword kconfig: use bool instead of boolean for type definition attributes, again kconfig: Remove menu_end_entry() kconfig: Document important expression functions kconfig: Document automatic submenu creation code kconfig: Fix choice symbol expression leak ...
| * kbuild: prepare to remove C files pre-generated by flex and bisonMasahiro Yamada2017-12-161-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Linux build system convention, pre-generated files are version- controlled with a "_shipped" suffix. During the kernel building, they are simply shipped (copied) removing the suffix. This approach can reduce external tool dependency for the kernel build, but it is tedious to manually regenerate such artifacts from developers' point of view. (We need to do "make REGENERATE_PARSERS=1" every time we touch real source files such as *.l, *.y) Some months ago, I sent out RFC patches to run flex, bison, and gperf during the build. In the review and test, Linus noticed gperf-3.1 had changed the lookup function prototype. Then, the use of gperf in kernel was entirely removed by commit bb3290d91695 ("Remove gperf usage from toolchain"). This time, I tested several versions of flex and bison, and I was not hit by any compatibility issue except a flaw in flex-2.6.3; if you generate lexer for dtc and genksyms with flex-2.6.3, you will see "yywrap redefined" warning. This was not intentional, but a bug, fixed by flex-2.6.4. Otherwise, both flex and bison look fairly stable for a long time. This commit prepares some build rules to remove the _shipped files. Also, document minimal requirement for flex and bison. Rationale for the minimal version: The -Wmissing-prototypes option of GCC warns "no previous prototype" for lexers generated by flex-2.5.34 or older, so I chose 2.5.35 as the required version for flex. Flex-2.5.35 was released in 2008. Bison looks more stable. I did not see any problem with bison-2.0, released in 2004. I did not test bison-1.x, but bison-2.0 should be old enough. Tested flex versions: 2.5.35 2.5.36 2.5.37 2.5.39 2.6.0 2.6.1 2.6.2 2.6.3 (*) 2.6.4 (*) flex-2.6.3 causes "yywrap redefined" warning Tested bison versions: 2.0 2.1 2.2 2.3 2.4 2.4.1 2.5.1 2.6 2.6.1 2.6.2 2.6.3 2.6.4 2.6.5 2.7 2.7.1 3.0 3.0.1 3.0.2 3.0.3 3.0.4 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Way back in 2008 we didn't have "robust" in-kernel documentation system, so the idea of putting something like the kernel driver statement in the kernel tree wasn't even imagined. But now that has changed, so add the old document to the kernel source itself to allow for us to properly reference it in one canonical place (as the LF wiki keeps moving things around.) This also will allow people to add their names to it, as I seem to have lost the ability to do that by not knowing how to edit things on the original document.

THIN_ARCHIVES has been available for a while as an optional feature only for PowerPC architecture, but we do not need two different intermediate-artifact schemes. Using thin archives instead of conventional incremental linking has various advantages: - save disk space for builds - speed-up building a little - fix some link issues (for example, allyesconfig on ARM) due to more flexibility for the final linking - work better with dead code elimination we are planning As discussed before, this migration has been done unconditionally so that any problems caused by this will show up with "git bisect".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 2014, you can't successfully build kernels with GNU Make version 3.80. Example errors: $ git describe v4.11 $ make --version | head -1 GNU Make 3.80 $ make defconfig HOSTCC scripts/basic/fixdep scripts/Makefile.host:135: *** missing separator. Stop. make: *** [defconfig] Error 2 $ make ARCH=arm64 help arch/arm64/Makefile:43: *** unterminated call to function `warning': missing `)'. Stop. $ make help >/dev/null ./Documentation/Makefile.sphinx:25: Extraneous text after `else' directive ./Documentation/Makefile.sphinx:31: *** only one `else' per conditional. Stop. make: *** [help] Error 2 The first breakage was introduced by commit c8589d1e9e01 ("kbuild: handle multi-objs dependency appropriately"). Since then (i.e. v3.18), GNU Make 3.80 has not been able to compile the kernel, but nobody has ever complained aboutt (or noticed) it. Even GNU Make 3.81 is more than 10 years old. It would not hurt to match the documentation with reality instead of fixing makefiles.
