From: xujialu <xujialu@xxxxxxxxx>
Subject: scripts/tags.sh: support compiled source, improved precise
Original 'COMPILED_SOURCE=1 make cscope' collects nearly 30000 files
include too many unused files, this patch precisely collects source
files from *.cmd, in this case just 3000 files include dts and dtsi.
Usage:
1) COMPILED_SOURCE=1 make {cscope,gtags}
2) COMPILED_SOURCE=1 KBUILD_ABS_SRCTREE=1 make {cscope,gtags}
3) COMPILED_SOURCE=1 ./scripts/tags.sh {cscope,gtags}
4) COMPILED_SOURCE=1 ABSPWD=$PWD/ ./scripts/tags.sh {cscope,gtags}
