             Bug #: 13129
           Summary: avr-gas lacks documentation of gs() modifier
           Product: binutils
           Version: 2.21
               URL: http://sourceware.org/binutils/docs-2.21/as/AVR_002dMo
                    difiers.html#AVR_002dModifiers
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: gas
        AssignedTo: unassigned@sources.redhat.com
        ReportedBy: gjl@gcc.gnu.org
                CC: bjoern.m.haase@web.de
    Classification: Unclassified
            Target: avr


In the documentation of "Relocatable Expression Modifiers"

Machine Dependencies -> AVR-Dependent -> AVR Syntax -> AVR-Modifiers

http://sourceware.org/binutils/docs-2.21/as/AVR_002dModifiers.html#AVR_002dModifiers

there is no documentation for gs() modifier (and maybe others).

Moreover, description of, e.g. pm_lo8, is very unprecise; it just states that
it is "useful for addressing data or code from Flash/Program memory" but does
not specify what it really does.
