can anybody tell me a "case" which cannot be covered by VALUE
NUMBERING and covered by Common subexpression elimination.
personally i believe that Value numbering is Superior to common
subexpression elimination and value numbering can optimize all the
common subexpressions that can be optimized by common subexpression

thanks in advance,

Keep Smiling
