135 | # In "testsuite/config/unix-gdb.exp", the routine "gdb_load" | |
136 | # is defined as "gdb_file_cmd". The binding of "gdb_file_cmd" | |
137 | # is done at invocation time. Before this file is processed, | |
138 | # it binds to the definition in "testsuite/lib/gdb.exp"; after | |
139 | # this file is processed, it binds to this definition. | |
140 | # TCL lets us overrides a previous routine definition without a | |
141 | # warning (isn't that special?). | |
142 | # | |
143 | # This means that tests before use "file" to load a target, and | |
144 | # tests afterwards use the pair "symbol-file" "exec-file". | |
145 | # | |
146 | # I'm leaving it as it is for now because at the moment it | |
147 | # is the only test we have of the use of the combination of | |
148 | # "symbol-file" and "exec-file" to load a debugging target (the | |
149 | # other definition uses "file". | |
150 | # | |
151 | # Symbol-file and exec-file should be tested explicitly, not | |
152 | # as a side effect of running a particular test (in this case, | |
153 | # "testsuite/gdb.compat/dbx.exp"). | |
154 | # | |
155 | # CM: Renamed the procedure so it does not override the orginal file name. | |
156 | # Having the test suite change behavior depending on the tests run makes | |
157 | # it extremely difficult to reproduce errors. I've also added a | |
158 | # "dbx_gdb_load" procedure. This and only this test will call these | |
159 | # procedures now. I also added an "expect" to the "send exec-file" line. | |
160 | # The "expect" waits for a prompt to appear. Otherwise, if the tests run | |
161 | # too quickly, the caller could send another command before the prompt | |
162 | # of this command returns, causing the test to get out of sync and fail | |
163 | # seemingly randomly or only on a loaded system. | |
164 | # | |
7be570e7 JM |
165 | # Problem is, though, that the testsuite config files can override the definition of |
166 | # gdb_load (without notice, as was mentioned above). Unfortunately, the gdb_load proc | |
167 | # that was copied into this test was a copy of the unix native version. | |
168 | # | |
169 | # The real problem that we're attempting to solve is how to load an exec and symbol | |
170 | # file into gdb for a dbx session. So why not just override gdb_file_cmd with the | |
171 | # right sequence of events, allowing gdb_load to do its normal thing? This way | |
172 | # remotes and simulators will work, too. | |
