Subject: [Ada] Attach the special GNATprove HEAP entity to the Standard package
X-Git-Tag: upstream/12.2.0~30336
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7abe752684b9afa6aa4bf4f293c9f2e13bd38835;p=platform%2Fupstream%2Fgcc.git

[Ada] Attach the special GNATprove HEAP entity to the Standard package

In GNATprove mode we use frontend cross-references to synthesize the
Global contract of subprograms with SPARK_Mode => Off and represent
a read/write via a pointer as a read/write of a special entity called
HEAP. This entity is now attached to the Standard package, so that we can
safely check the Ekind of its Scope, which now happens in Scope_Within.

This only affects GNATprove, so no frontend test provided.
