--- Comment #1 from Jason Merrill <jason at gcc dot gnu.org> 2012-05-07 14:21:30 UTC --- <21e> is there as a local stub so that multiple references to the same .debug_types type can use (smaller) local DIE references instead of all needing to use DW_FORM_sig8. The testcase is failing because of the change from "A*" to "struct A*"? Is that an important distinction? If so, could you handle the case of a nameless typedef specially on your end?
