llvm/clang static analyzer reports

[Maarten Hoes]

Hi,


Bugzilla bug report #39596 [1] is talking about finding a way to run
automated reports of the llvm/clang static analyzer on the libreoffice
codebase. I mentioned I was looking into picking this up briefly on irc,
and it was suggested to just do a manual run first, just to see if results
might be useful.

I managed to do a full clang-analyzer run on the libreoffice codebase, and
uploaded the tar.gz html results to google drive [2]. I honestly have no
idea if the results are valid/useful though. Perhaps someone could take a
look at them ? As mentioned, the results should be here [2].

It looks like a lot, but it also seems that the same file(s) and line is
included lots of times (for example, core/include/rtl/ref.hxx, function
get, line 192, is listed a lot). As far as i can tell, the analyzer is
supposed to filter these and only include one of the duplicates in the
final report instead of listing all of them, so something must be going
wrong here.

For what it's worth: the entire run took about 4 hours to complete on my
system (Intel Core i7-10700, 32GB RAM)


Sincerely,


Maarten Hoes
