            Bug ID: 31267
           Summary: Bad hint when listing before reading symbols
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: cli
          Assignee: unassigned at sourceware dot org
          Reporter: blarsen at redhat dot com
  Target Milestone: ---

If a user tries to list source lines before GDB reads the inferior's symbol=
s,
they get the following error message:

    (gdb) list
    No symbol table is loaded.  Use the "file" command.

However, the error persists when the command is used, like so:

    (gdb) file ~/a.out=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=
=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20
    Reading symbols from ~/a.out...=20=20=20=20=20=20=20=20=20=20=20=20=20=
=20=20=20=20=20=20=20=20
    (No debugging symbols found in ~/a.out)=20=20=20=20=20=20=20=20=20=20=
=20=20=20
    (gdb) list=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=
=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20
    No symbol table is loaded.  Use the "file" command.=20

GDB should instead realize if the command has been used and instead tell the
user that symbols haven't been read yet (and suggest a command, eitehr 'sta=
rt'
or some command to read the symbols)
