From a680eedc6c621c75695c68198533fc3c98f4053b Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Wed, 3 Dec 2008 22:24:13 +0100 Subject: tags and cscope support really belongs in a shell script as they do not benefit from the make functionality. Moving the support to a shell script has several benefits: - The readability of the code has increased a lot - More people is able to extend the tags support - We see less changes to the top-level Makefile The shell script version includes improvements from: Alexey Dobriyan (jump to kconfig symbols) Alexey Dobriyan (drop ./ in paths) Ian Campbell (simplified find algorithms) This version has a few caveats: => It does not support ALLSOURCE_ARCHS - it is easy to add if it is really used => It assumes all archs have moved to arch/$ARCH/include - until that happens we have a few additional hits in the archs Signed-off-by: Sam Ravnborg Cc: Alexey Dobriyan Tested-by: Ian Campbell --- Makefile | 117 ++------------------------------------------------------------- 1 file changed, 3 insertions(+), 114 deletions(-) (limited to 'Makefile') diff --git a/Makefile b/Makefile index 3a6ac688f38..be462cf3cdc 100644 --- a/Makefile +++ b/Makefile @@ -1409,123 +1409,12 @@ endif # KBUILD_EXTMOD # Generate tags for editors # --------------------------------------------------------------------------- +quiet_cmd_tags = GEN $@ + cmd_tags = $(CONFIG_SHELL) $(srctree)/scripts/tags.sh $@ -#We want __srctree to totally vanish out when KBUILD_OUTPUT is not set -#(which is the most common case IMHO) to avoid unneeded clutter in the big tags file. -#Adding $(srctree) adds about 20M on i386 to the size of the output file! - -ifeq ($(src),$(obj)) -__srctree = -else -__srctree = $(srctree)/ -endif - -ifeq ($(ALLSOURCE_ARCHS),) -ifeq ($(ARCH),um) -ALLINCLUDE_ARCHS := $(ARCH) $(SUBARCH) -else -ALLINCLUDE_ARCHS := $(SRCARCH) -endif -else -#Allow user to specify only ALLSOURCE_PATHS on the command line, keeping existing behaviour. -ALLINCLUDE_ARCHS := $(ALLSOURCE_ARCHS) -endif - -ALLSOURCE_ARCHS := $(SRCARCH) - -define find-sources - ( for arch in $(ALLSOURCE_ARCHS) ; do \ - find $(__srctree)arch/$${arch} $(RCS_FIND_IGNORE) \ - -wholename $(__srctree)arch/$${arch}/include/asm -type d -prune \ - -o -name $1 -print; \ - done ; \ - find $(__srctree)security/selinux/include $(RCS_FIND_IGNORE) \ - -name $1 -print; \ - find $(__srctree)include $(RCS_FIND_IGNORE) \ - \( -name config -o -name 'asm-*' \) -prune \ - -o -name $1 -print; \ - for arch in $(ALLINCLUDE_ARCHS) ; do \ - test -e $(__srctree)include/asm-$${arch} && \ - find $(__srctree)include/asm-$${arch} $(RCS_FIND_IGNORE) \ - -name $1 -print; \ - test -e $(__srctree)arch/$${arch}/include/asm && \ - find $(__srctree)arch/$${arch}/include/asm $(RCS_FIND_IGNORE) \ - -name $1 -print; \ - done ; \ - find $(__srctree)include/asm-generic $(RCS_FIND_IGNORE) \ - -name $1 -print; \ - find $(__srctree) $(RCS_FIND_IGNORE) \ - \( -name include -o -name arch -o -name '.tmp_*' \) -prune -o \ - -name $1 -print; \ - ) -endef - -define all-sources - $(call find-sources,'*.[chS]') -endef -define all-kconfigs - $(call find-sources,'Kconfig*') -endef -define all-defconfigs - $(call find-sources,'defconfig') -endef - -define xtags - if $1 --version 2>&1 | grep -iq exuberant; then \ - $(all-sources) | xargs $1 -a \ - -I __initdata,__exitdata,__acquires,__releases \ - -I __read_mostly,____cacheline_aligned,____cacheline_aligned_in_smp,____cacheline_internodealigned_in_smp \ - -I EXPORT_SYMBOL,EXPORT_SYMBOL_GPL \ - --extra=+f --c-kinds=+px \ - --regex-asm='/^ENTRY\(([^)]*)\).*/\1/'; \ - $(all-kconfigs) | xargs $1 -a \ - --langdef=kconfig \ - --language-force=kconfig \ - --regex-kconfig='/^[[:blank:]]*(menu|)config[[:blank:]]+([[:alnum:]_]+)/\2/'; \ - $(all-defconfigs) | xargs -r $1 -a \ - --langdef=dotconfig \ - --language-force=dotconfig \ - --regex-dotconfig='/^#?[[:blank:]]*(CONFIG_[[:alnum:]_]+)/\1/'; \ - elif $1 --version 2>&1 | grep -iq emacs; then \ - $(all-sources) | xargs $1 -a; \ - $(all-kconfigs) | xargs $1 -a \ - --regex='/^[ \t]*\(\(menu\)*config\)[ \t]+\([a-zA-Z0-9_]+\)/\3/'; \ - $(all-defconfigs) | xargs -r $1 -a \ - --regex='/^#?[ \t]?\(CONFIG_[a-zA-Z0-9_]+\)/\1/'; \ - else \ - $(all-sources) | xargs $1 -a; \ - fi -endef - -quiet_cmd_cscope-file = FILELST cscope.files - cmd_cscope-file = (echo \-k; echo \-q; $(all-sources)) > cscope.files - -quiet_cmd_cscope = MAKE cscope.out - cmd_cscope = cscope -b -f cscope.out - -cscope: FORCE - $(call cmd,cscope-file) - $(call cmd,cscope) - -quiet_cmd_TAGS = MAKE $@ -define cmd_TAGS - rm -f $@; \ - $(call xtags,etags) -endef - -TAGS: FORCE - $(call cmd,TAGS) - -quiet_cmd_tags = MAKE $@ -define cmd_tags - rm -f $@; \ - $(call xtags,ctags) -endef - -tags: FORCE +tags TAGS cscope: FORCE $(call cmd,tags) - # Scripts to check various things for consistency # --------------------------------------------------------------------------- -- cgit v1.2.3
