Hi,
=20
I'm porting GDB 6.6 to our target and one of my users reported a problem
with the command 'info reg sp'. Having done some digging it seems the
following code in infcmd.c is causing me problems:

 int regnum =3D frame_map_name_to_regnum (deprecated_selected_frame,
            start, end - start);
 if (regnum >=3D 0)
   {
     gdbarch_print_registers_info (current_gdbarch, gdb_stdout,
       deprecated_selected_frame, regnum, fpregs);
     continue;
   }

The problem is that frame_map_name_to_regnum returns a value greater
than NUM_REGS+NUM_PSEUDO_REGS because there is a builtin user reg by
that name which is returned by user_reg_map_name_to_regnum. The question
is: should my print_registers_info be able to handle this (if so how? I
suppose by calling value_of_user_reg) or is this code broken?

Many thanks,

Robert Norton
