To make progress I think we'll need to look at the generated code and
figure out why it is so bad. By far the worst result seems to be for
STRATCOMP1-ALL:
> |2.95 -O2|2.95 -O3| 3.0 -O2| 3.0 -O3|3.0.1-O2|3.0.1-O3|
> ---------------------+-----------------------------------------------------+
> STRATCOMP1-ALL | 8.26 | 8.07 | 94.42 | 94.50 | 107.90 | 103.03 |
Can you try to isolate where the bad code is?
