Understanding the dependency to a-calend.adb introduced by gnatcoll-xref.adb in gnatcoll-xref.ali

Understanding the dependency to a-calend.adb introduced by gnatcoll-xref.adb in gnatcoll-xref.ali

[David SAUVAGE]

Hi.all,

This is a GNAT specific topic, we are trying to understand why a dependency to Ada.Calendar implementation is introduced by the GNATColl.Xref unit in the gnatcoll-xref.ali [2] Ada Library Information [1] file

I would suppose this could be needed in the case of generic-related-uses, but as that does not seem to be the case here, I would expect only a dependency to a-calend.ads 

Any feedbacks are most welcome,

Cheers

There are a whole lot of pragma Inline's in Ada.Calendar'spec (in the
private part).

Oh yes many thanks Simon, I missed that the GNATColl.Xref unit has been built with -O2.
