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.
