--- Comment #10 from Heinrich Seebauer <heinrich.seebauer at swistec dot de> ---
Alexander, you are right, it is only strange behaviour. Using -O1 drops the
'then' clause, but the results are the same, if one takes a broader view.
The program deals with controlling schedules using actual time. Each test run
has different input values (current UTC time). I set up a situation where I was
able to control system time, and the outcomes were consistent, either using -O0
oe -O1.
What confused me was the fact that -O2/-Os did NOT drop the then clause. So -O2
ist not just optimizing the -O1 outcome, but different from the beginning of
the optimizer pass.
I apologize for not getting this point quickly.
Thank you very much for your support and your work for the commuinty,
kind regards
Heinrich
