On a riscv64-linux system (HiFive Unleashed w/ Fedora Core 29), without 
an Ada compiler in my path, I get

                 === gdb Summary ===

# of expected passes            50264
# of unexpected failures        2297
# of expected failures          57
# of unknown successes          3
# of known failures             79
# of untested testcases         132
# of unresolved testcases       110
# of unsupported tests          359

which looks OK.  There was no riscv-linux native support in gdb-8.2 so 
this is a major improvement over the last one.  I did used to have 
better results though.  I'm seeing

hifiveu017:1040$ grep ^FAIL gdb.sum | grep infcall | wc
     878    8059  103059

and I think that these mostly used to work, since I used to have about 
1500 failures.  I think something in the last 3 months broke this, but I 
haven't had time to track it down.  I see stuff like this in the log files
