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