short answer:

gdb/testsuite/gdb.base/gdbserver.exp

long answer:

There are two ways of testing stuff like separate debug info and gdb-server:

- as part of full and separate dejagnu test run
eg: make check RUNTESTFLAGS=--target_board=gdbserver

- as a small focused functional / unit test
eg: make check RUNTESTFLAGS=gdbserver.exp

Both are correct as both offer distinct advantages and disadvantages 
(mind you I should note that I've witnessed argument disputing this :-). 
  The former provides better coverage, but with no realistic expectation 
that the average GDB developer will ever run it; while the later ensures 
that that specific functionality is always working, but lacks broad 
coverage.

A gdbserver.exp unit test would significantly improve the odds of 
gdbserver working with a standard GDB.  It would also make possible the 
writing of gdbserver specific tests that explore edge cases missed by 
the more standard tests (the attach / detach behavior for instance). 
Also, in support of this, even though separate debug info bit rot and 
broke within months of its initial commit, the breakage wasn't noticed 
for several further months (when the unit test was added).
