Bootstrapped and regtested on i686-pc-linux-gnu. Okay for mainline?
That doesn't seem right to me, as this type is indeed local to a function.
I'd say that DECL_CONTEXT applied to the type should indeed be a
See dwarf2out.c add_abstract_origin_attribute
The if part this code is in is just trying to make sure the containing
function got written out (which is actually already should have now that
we do it in cgraph, but i didn't want to play with this already fragile
code for 4.0).
So it's just fine if it can't find one.
It has nothing to do with looking up the "context" of the original type,
that is done a few lines later.
That means that either TYPE_STUB_DECL should be non-NULL
tree.h's docs on TYPE_STUB_DECL gives me the distinct impression that
TYPE_STUB_DECL is optional, and may be NULL.
