# 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.
