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. 162# 163# Problem is, though, that the testsuite config files can override the definition of 164# gdb_load (without notice, as was mentioned above). Unfortunately, the gdb_load proc 165# that was copied into this test was a copy of the unix native version. 166# 167# The real problem that we're attempting to solve is how to load an exec and symbol 168# file into gdb for a dbx session. So why not just override gdb_file_cmd with the 169# right sequence of events, allowing gdb_load to do its normal thing?
