Currently looking up a structure definition in TAGS / tags takes one to one of multiple "static struct X" definitions in arch sources, which makes it for many structs practically impossible to get to the required header. This patch changes the order of sources being tagged to first scan architecture includes, then the top-level include/ directory, and only then the rest. It also takes into account, that many architectures have more than one include directory, i.e., not only arch/$ARCH/include, but also arch/$ARCH/mach-X/include etc. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@xxxxxx> --- I am no expert in Kbuild, so, please, review, comment, suggest improvements, but at least, this does make TAGS usable for me. diff --git a/scripts/tags.sh b/scripts/tags.sh index 1a0c44d..b84ce1c 100755 --- a/scripts/tags.sh +++ b/scripts/tags.sh @@ -32,13 +32,18 @@ fi # find sources in arch/$ARCH find_arch_sources() { - find ${tree}arch/$1 $ignore -name "$2" -print; + for i in $archincludedir; do + prune+="-wholename $i -prune -o " + done + find ${tree}arch/$1 $ignore $prune -name "$2" -print; } # find sources in arch/$1/include find_arch_include_sources() { - find ${tree}arch/$1/include $ignore -name "$2" -print; + include=$(find ${tree}arch/$1/ -name include -type d); + archincludedir+=$include + find $include $ignore -name "$2" -print; } # find sources in include/ @@ -63,14 +68,15 @@ find_sources() all_sources() { - for arch in $ALLSOURCE_ARCHS - do - find_sources $arch '*.[chS]' - done + find_arch_include_sources $ARCH '*.[chS]' if [ ! -z "$archinclude" ]; then find_arch_include_sources $archinclude '*.[chS]' fi find_include_sources '*.[chS]' + for arch in $ALLSOURCE_ARCHS + do + find_sources $arch '*.[chS]' + done find_other_sources '*.[chS]' } -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
