No, I think we can spare those cycles there.

Hi All,
Thanks a lot for your comments.
I've re-written reorder_operands as you proposed, but I'd like to know
if we should apply this reordering at -O0?
I will re-send the patch after testing completion.
Thanks.
Yuri.

Hi All,
Here is a patch which fixed several performance degradation after
operand canonicalization (r216728). Very simple approach is used - if
operation is commutative and its second operand required more
operations (statements) for computation, swap operands.
Currently this is done under special
