Make test messages unique and a couple other tweaks. gdb/testsuite/ 2014-09-16 Sergio Durigan Junior <sergiodj@redhat.com> Pedro Alves <palves@redhat.com> * gdb.base/watch-bitfields.exp: Pass string other than test file name to prepare_for_testing. (watch): New procedure. (expect_watchpoint): Use with_test_prefix. (top level): Factor out tests to ... (test_watch_location, test_regular_watch): ... these new procedures, and use with_test_prefix and gdb_continue_to_end.
