           Summary: backport r158175: replace dominated uses in
                    loop-invariant
           Product: gcc
           Version: 4.4.5
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: big...@acm.org


While updating the msp430 back-end, I've discovered that the problem fixed in
trunk in revision 158175 bites me as well in 4.4.x and 4.5.x.  This is a
request to back-port the corresponding fix to gcc-4_4-branch and
gcc-4_5-branch.
