[llvm-dev] AOSP buildbot fails with assert in :ScheduleDAGRRList::PickNodeToScheduleBottomUp

Hi Pengxuan,

I just saw that the newly added AOSP buildbot allready builds LLVM very
nicely. However, it is still red due to the following assertion:

Do you happen to have a reduced test case for this or does there even
exist a bug report?
