Old Synopsis: redundant comparison introduced with gcc-3.0 (regression from gcc 2)
New Synopsis: redundant conditional branch

State-Changed-From-To: open->analyzed
State-Changed-By: rth
State-Changed-When: Tue Apr  2 19:53:47 2002
State-Changed-Why:

            jle     .L8
            incl    %eax
    .L8:
    
    However, I'm not closing the PR since we really should have
    eliminated one of the branches.
