| 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?). |
| 139 | # |
| 140 | # This means that tests before use "file" to load a target, and |
| 141 | # tests afterwards use the pair "symbol-file" "exec-file". |
| 142 | # |
| 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". |
| 147 | # |
| 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"). |
| 151 | # |
| 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. |
| 161 | # |
| 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. |
| 165 | # |
| 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. |
| 170 | # |
| 171 | # [drow 2002-03-30]: We can restore the old gdb_file_cmd afterwards, though. |
