* alias.h (record_alias_subset): Declare.
* alias.c (record_alias_subset): Make global.
ada/
* gcc-interface/decl.c (enum alias_set_op): New enumeration.
(copy_alias_set): Rename into...
(relate_alias_sets): ...this. Add third parameter OP. Retrieve the
underlying array of unconstrained arrays for the new type as well.
If the old and new alias sets don't conflict, make one a subset of
the other as per the OP parameter.
(gnat_to_gnu_entity): Adjust calls to copy_alias_set.
<E_Record_Type>: Do not copy the alias set for derived types.
For all types, make the alias set of derived types a superset of
that of their parent type.
(make_aligning_type): Adjust calls to copy_alias_set.
(make_packable_type): Likewise.
* gcc-interface/trans.c (gnat_to_gnu)<N_Validate_Unchecked_Conversion>:
Check for alias set conflict instead of strict equality to issue the
warning.
