 133 # In "testsuite/config/unix-gdb.exp", the routine "gdb_load"
 134 # is defined as "gdb_file_cmd".  The binding of "gdb_file_cmd"
 135 # is done at invocation time.  Before this file is processed,
 136 # it binds to the definition in "testsuite/lib/gdb.exp"; after
 137 # this file is processed, it binds to this definition.
 138 # TCL lets us overrides a previous routine definition without a
 139 # warning (isn't that special?).
 140 #
 141 # This means that tests before use "file" to load a target, and
 142 # tests afterwards use the pair "symbol-file" "exec-file".
 143 #
 144 # I'm leaving it as it is for now because at the moment it
 145 # is the only test we have of the use of the combination of
 146 # "symbol-file" and "exec-file" to load a debugging target (the
 147 # other definition uses "file".
 148 #
 149 # Symbol-file and exec-file should be tested explicitly, not
 150 # as a side effect of running a particular test (in this case,
 151 # "testsuite/gdb.compat/dbx.exp").
 152 #
 153 # CM: Renamed the procedure so it does not override the orginal file name.
 154 #     Having the test suite change behavior depending on the tests run makes
 155 #     it extremely difficult to reproduce errors. I've also added a
 156 #     "dbx_gdb_load" procedure.  This and only this test will call these
 157 #     procedures now. I also added an "expect" to the "send exec-file" line.
 158 #     The "expect" waits for a prompt to appear. Otherwise, if the tests run
 159 #     too quickly, the caller could send another command before the prompt
 160 #     of this command returns, causing the test to get out of sync and fail
 161 #     seemingly randomly or only on a loaded system.
