  82 # In "testsuite/config/unix-gdb.exp", the routine "gdb_load"
  83 # is defined as "gdb_file_cmd".  The binding of "gdb_file_cmd"
  84 # is done at invocation time.  Before this file is processed,
  85 # it binds to the definition in "testsuite/lib/gdb.exp"; after
  86 # this file is processed, it binds to this definition.
  87 # TCL lets us overrides a previous routine definition without a
  88 # warning (isn't that special?).
  89 #
  90 # This means that tests before use "file" to load a target, and
  91 # tests afterwards use the pair "symbol-file" "exec-file".
  92 #
  93 # I'm leaving it as it is for now because at the moment it
  94 # is the only test we have of the use of the combination of
  95 # "symbol-file" and "exec-file" to load a debugging target (the
  96 # other definition uses "file".
  97 #
  98 # Symbol-file and exec-file should be tested explicitly, not
  99 # as a side effect of running a particular test (in this case,
 100 # "testsuite/gdb.compat/dbx.exp").
