           Summary: Can not get symtab_and_line object given an arbitrary
                    program counter
           Product: gdb
           Version: 7.2
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: python
        AssignedTo: unassigned@sourceware.org
        ReportedBy: er_31337@yahoo.com


There is no (obvious) documented way to get a symtab_and_line object given an
arbitrary address.  
A function gdb.sal_for_pc() similar to gdb.block_for_pc() would be nice.

you can get a symtab_and_line object for an arbitrary address by using the
decode_line function (see the Basic Python section of the manual) and passing
in "*0xaddr" as the argument.

e.g. 
(gdb) python print gdb.decode_line("*" +
str(gdb.selected_frame().find_sal().pc))
(None, (<gdb.Symtab_and_line object at 0x7f55269cbe10>,))
(gdb)

I've suggested adding a reference to decode_line from the gdb.symtab_and_line
section.
If you have any recommendations how to further clarify the manual please let us
know.
