Has something changed in LLVM BUG tracking system ?

Hi all,

I've submitted following two bugs a few weeks ago:

http://llvm.org/bugs/show_bug.cgi?id=15309

http://llvm.org/bugs/show_bug.cgi?id=15298

Those two problems are related to vector code generation for x86, one of htem is AVX specific.
With previous BUG I've submitted, there are always people that put them in CC list within the day of submission to track bug status.
Here there hasn't been any activity on the BUG submitted, I'm just wondering if that's because something has changed or just because nobody has time/interest into looking at those problems ?

Thanks for your answers
Best Regards
Seb
