+
+ * atree.adb: Minor reformatting
+
+ * exp_ch3.adb (Expand_Derived_Record): Rename to
+ Expand_Record_Extension.
+ (Build_Record_Init_Proc.Build_Assignment): The default expression in
+ a component declaration must remain attached at that point in the

+ It is therefore necessary to take a copy of the expression when building
+ the corresponding assignment statement in the init proc.

+ * sinfo.ads: Fix typo in comment.
+
+ * sem_dist.adb (Process_Remote_AST_Attribute): Simplify code that uses
+ the TSS for remote access-to-subprogram types, since these TSS are
+ always present once the type has been analyzed.
+ (RAS_E_Dereference): Same.
+
+ * sem_attr.adb (Analyze_Attribute): When analysis of an attribute
+ reference raises Bad_Attribute, mark the reference as analyzed so the

+
+ * exp_ch7.ads (Find_Final_List): Fix misaligned comment.
+
+ * exp_dist.adb: Minor comment fix.
+
+ * exp_ch4.adb (Expand_N_Allocator): For an allocator whose expected

+ allocated object can occur. If the object is controlled, attach it with
+ a count of 1. This allows attachment to the Global_Final_List, if
+ no other relevant list is available.
+ (Get_Allocator_Final_List): For an anonymous access type that is
+ the type of a discriminant or record component, the corresponding
+ finalisation list is the one of the scope of the type.

+ used as an actual.

+ "not conformant with previous declaration" is emitted if an error is
+ detected.
