Subject: Re: [Ping^2, Patch, Fortran] PR100337 Should be able to pass non-present optional arguments to CO_BROADCAST

Hi Tobias,
thanks for the review.
To the questions:
- I added a test only for -fcoarray=single because in the library case the
optional stat is just propagated to the library, which is already tested a
lot of times and which needs to handle the optional stat in any case. So an
error there would have been detected in one of the earlier tests. I did not
want to add unnecessary test overhead given that the tests already run for a
long time.
- I did not add tests for the other CO_* routines, i.e. CO_MIN, CO_MAX,
CO_REDUCE or CO_SUM, that are also handled by this routine, because I believe
that showing that the fix works for CO_BROADCAST shows that the others work,
too. Because the four others do not have any special handling in their
implementation in trans_intrinsic. Or do you mean other coarray-routines
besides the five handled by conv_co_collective()?
If it is ok for you, I would apply the patch as is, or do you see a reason to
add more tests?
Regards,
Andre
