Paolo Carlini <paolo.carlini at oracle dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at gcc dot gnu.org --- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> --- Jason, looks like some bits related to debugging are missing from the work on return type deduction and people cannot debug uses of the new facility. gen_type_die_with_usage gets a TEMPLATE_TYPE_PARM which doesn't know how to handle. Is it just matter of somehow having an equivalent of is_auto and using a DW_TAG_unspecified_type? Or we shouldn't have a TEMPLATE_TYPE_PARM at all at this point? (I don't see what else) ... or you prefer to look a bit into this? ;)
