Subject: [Ada] Set dummy Etype for the fake __HEAP entity in GNATprove
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=56730418631c887e3c20f6529ed9399b80b50915;p=gcc.git

[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.
