            Bug ID: 118768
           Summary: [avr] Make genmultilib.awk more robust against white
                    spaces
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gjl at gcc dot gnu.org
  Target Milestone: ---

The current genmultilib.awk is prone to errors when avr-mmcu.def adds or
removed white spaces.  For example, AVR_ATTR1|AVR_ATTR2 will be parsed not the
same like AVR_ATTR1 | AVR_ATTR2.
