Re: optimization/5263: a & b & ~a & ~b not optimized


Old Synopsis: Poor optimization for expression with more than three operands
New Synopsis: a & b & ~a & ~b not optimized

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Sat Mar 15 04:26:14 2003
State-Changed-Why:
    Confirmed. Behavior persists on mainline. While
      a & b & ~a & ~b
    is not optimized, the reordered expression
      a & ~a & b & ~b
    is.
    
    W.
