- Subject: [Ada] Set dummy Etype for the fake __HEAP entity in GNATprove
GNATprove represents reads and writes via pointers as operations on a
fake __HEAP entity. This entity already had various properties set to
dummy values (e.g. Scope set to Standard_Standard), so that it can be
processed like other entities without crashing and not special-cased
everywhere. Now it also has a dummy Etype, so it can be processed with
Is_Single_Concurrent_Object.
The modified code is only executed by GNATprove; frontend is not
affected.
Tested on x86_64-pc-linux-gnu, committed on trunk
