The problem is that during dce the call to is_hidden_global_store returns false
cause the tag is not marked as global/static.
This seems to fix it:
Index: tree-ssa-alias.c
===================================================================
*** tree-ssa-alias.c (revision 110911)
--- tree-ssa-alias.c (working copy)
*************** new_type_alias (tree ptr, tree var)
*** 2638,2643 ****
--- 2638,2651 ----
add_may_alias (tag, al);
}
}
+
+ /* CHECKME:
+ DECL_CONTEXT (tag) = DECL_CONTEXT (var);
+ TREE_PUBLIC (tag) = TREE_PUBLIC (var);
+ TREE_READONLY (tag) = TREE_READONLY (var);
+ */
+ MTAG_GLOBAL (tag) = DECL_EXTERNAL (var);
+ TREE_STATIC (tag) = TREE_STATIC (var);
}
but I don't know if it's the right thing to do in the general case.
