Hi Gary,

For some reason, we don't see you ChangeLog entry in the patch (although
the diffstat shows changes to it), but it looks like:

+2020-04-20  Gary Benson <gbenson@redhat.com>
+
+       * gdb/testsuite/gdb.trace/tspeed.c: Fix compilation error with
+       clang.

The filename should not have the gdb/testsuite part.
