I see the drap and some of the pr36728-1 fails in my test logs. I don't
understand how I failed to notice them when comparing results; I probably
mistakenly used an already-failing baseline. I'll look into this, thanks.

The last one is an unrelated issue, caused by
http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=190543
(you'll notice also that all of the C and C++ guality testing is not performed
any longer). The issue is that with the above change one needs to use GDB 7.5
or later (or at least have the constant class DW_AT_high_pc support patch
backported to GDB 7.4.*). Mark, can you point to the commit with the fix?
