             Bug #: 50820
           Summary: [avr] Use EIND consistently
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: documentation, wrong-code
          Severity: enhancement
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gjl@gcc.gnu.org
                CC: eric.weddington@atmel.com
            Target: avr


EIND is not used consistently by the compiler: Some places use EICALL/EIJMP,
others to PUSH __zero_reg__ prior to indirect jump by means of RET.

Moreover, the usage of EIND and its assertions need documentation.
