             Bug #: 50465
           Summary: [avr] Use insn attribute to depict if and how
                    instruction lengths have to be adjusted
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: target
        AssignedTo: gjl@gcc.gnu.org
        ReportedBy: gjl@gcc.gnu.org
            Target: avr


At current, avr.c:adjust_insn_length() uses bunch of C-code to find out if and
how instruction lengths have to be adjusted.

This can be done in a more legible way by means of a new insn attribute.
