132 # In "testsuite/config/unix-gdb.exp", the routine "gdb_load"
133 # is defined as "gdb_file_cmd". The binding of "gdb_file_cmd"
134 # is done at invocation time. Before this file is processed,
135 # it binds to the definition in "testsuite/lib/gdb.exp"; after
136 # this file is processed, it binds to this definition.
137 # TCL lets us overrides a previous routine definition without a
138 # warning (isn't that special?).
140 # This means that tests before use "file" to load a target, and
141 # tests afterwards use the pair "symbol-file" "exec-file".
143 # I'm leaving it as it is for now because at the moment it
144 # is the only test we have of the use of the combination of
145 # "symbol-file" and "exec-file" to load a debugging target (the
146 # other definition uses "file".
148 # Symbol-file and exec-file should be tested explicitly, not
149 # as a side effect of running a particular test (in this case,
150 # "testsuite/gdb.compat/dbx.exp").
152 # CM: Renamed the procedure so it does not override the orginal file name.
153 # Having the test suite change behavior depending on the tests run makes
154 # it extremely difficult to reproduce errors. I've also added a
155 # "dbx_gdb_load" procedure. This and only this test will call these
156 # procedures now. I also added an "expect" to the "send exec-file" line.
157 # The "expect" waits for a prompt to appear. Otherwise, if the tests run
158 # too quickly, the caller could send another command before the prompt
159 # of this command returns, causing the test to get out of sync and fail
160 # seemingly randomly or only on a loaded system.
162 # Problem is, though, that the testsuite config files can override the definition of
163 # gdb_load (without notice, as was mentioned above). Unfortunately, the gdb_load proc
164 # that was copied into this test was a copy of the unix native version.
166 # The real problem that we're attempting to solve is how to load an exec and symbol
167 # file into gdb for a dbx session. So why not just override gdb_file_cmd with the
168 # right sequence of events, allowing gdb_load to do its normal thing? This way
169 # remotes and simulators will work, too.
171 # [drow 2002-03-30]: We can restore the old gdb_file_cmd afterwards, though.
