  83 # In "testsuite/config/unix-gdb.exp", the routine "gdb_load"
  84 # is defined as "gdb_file_cmd".  The binding of "gdb_file_cmd"
  85 # is done at invocation time.  Before this file is processed,
  86 # it binds to the definition in "testsuite/lib/gdb.exp"; after
  87 # this file is processed, it binds to this definition.
  88 # TCL lets us overrides a previous routine definition without a
  89 # warning (isn't that special?).
  90 #
  91 # This means that tests before use "file" to load a target, and
  92 # tests afterwards use the pair "symbol-file" "exec-file".

  94 # I'm leaving it as it is for now because at the moment it
  95 # is the only test we have of the use of the combination of
  96 # "symbol-file" and "exec-file" to load a debugging target (the
  97 # other definition uses "file".
  98 #
  99 # Symbol-file and exec-file should be tested explicitly, not
 100 # as a side effect of running a particular test (in this case,
 101 # "testsuite/gdb.compat/dbx.exp").
