Synopsis: [3.2 regression] loop unroll bug with -march=k6-3

State-Changed-From-To: closed->open
State-Changed-By: sirl
State-Changed-When: Thu Nov 28 04:29:32 2002
State-Changed-Why:
    Reopen, backported fix From Dale causes a regression on powerpc-linux-gnu.
    The testcase gcc.c-torture/execute/961213-1.c now fails with -O2 -funroll-loops.
    Presumably the backported patch relies on some other changes in the mainline.
