> Since commit 22d651dcef536c75f75537290bf3da5038e68b6b ('selftests/powerpc:
> Import Anton's memcpy / copy_tofrom_user tests'), some source files in the
> tree appear as symlink.
> Until commit 8c38a5328af8080bc69a25b3e4e144b03eeea95e ('scripts/tags.sh:
> ignore code of user space tools'), those symlinks made cscope report some
> warnings:
>
> $ make ALLSOURCE_ARCHS=all O=./obj-cscope/ cscope
> GEN cscope
> cscope: cannot find
> file .../tools/testing/selftests/powerpc/copyloops/copyuser_power7.S
> cscope: cannot find
> file .../tools/testing/selftests/powerpc/copyloops/memcpy_64.S
> cscope: cannot find
> file .../tools/testing/selftests/powerpc/copyloops/memcpy_power7.S
> cscope: cannot find
> file .../tools/testing/selftests/powerpc/copyloops/copyuser_64.S

> In order to prevent the same kind of warnings to be triggered by future
> addition of symlinks, the best option is to ignore all symlinks when
> building the file list to be processed by cscope (and other tools
> supported by scripts/tags.sh).
>
> Ignoring symlinks won't hide source files from cscope (and others) as the
> target of these symlinks already appear somewhere else in the tree, and,
> as such, should be processed by cscope (or others).
>
> Note that, cscope, when used with -R option to make it find the files to
> process by itself, already skip symlinks: it's not expected that cscope
> access source files through symlink.

> On top of commit 8c38a5328af8080bc69a25b3e4e144b03eeea95e ('scripts/tags.sh:
> ignore code of user space tools'), scripts/tags.sh output from
> "make cscope tags TAGS" is the same with and without this patch: it doesn't
> seems to introduce any regression (on Fedora 20).
