gdb: Auto-loading verbose mode

 
 22.8.4 Displaying files tried for auto-load
 -------------------------------------------
 
 For better visibility of all the file locations where you can place
 scripts to be auto-loaded with inferior -- or to protect yourself
 against accidental execution of untrusted scripts -- GDB provides a
 feature for printing all the files attempted to be loaded.  Both
 existing and non-existing files may be printed.
 
    For example the list of directories from which it is safe to
 auto-load files (SeeAuto-loading safe path) applies also to
 canonicalized filenames which may not be too obvious while setting it
 up.
 
      (gdb) set debug auto-load on
      (gdb) file ~/src/t/true
      auto-load: Loading canned sequences of commands script "/tmp/true-gdb.gdb"
                 for objfile "/tmp/true".
      auto-load: Updating directories of "/usr:/opt".
      auto-load: Using directory "/usr".
      auto-load: Using directory "/opt".
      warning: File "/tmp/true-gdb.gdb" auto-loading has been declined
               by your `auto-load safe-path' set to "/usr:/opt".
 
 'set debug auto-load [on|off]'
      Set whether to print the filenames attempted to be auto-loaded.
 
 'show debug auto-load'
      Show whether printing of the filenames attempted to be auto-loaded
      is turned on or off.
