             Bug #: 52507
           Summary: [avr]: movmem loop for __memx address space uses wrong
                    loop label
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: wrong-code
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: g...@gcc.gnu.org


The __movmemx_hi and __movmemx_qi functions from libgcc use an incorrect loop
label for the RAM-copy part of their code.

Effect will be that after the first byte the read will be from Flash and not
from RAM.
