--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Iff we are sure abstract origin and BLOCK are never in the same SCC we can
fixup
during stream-in, but it's still somewhat ugly and it feels that we are losing
some debug info here (which clone we inlined).

when we'd stream this reference as DIE we would get away. But of course
esp. the FUNCTION_DECLs referenced as part of the inline BLOCKs are very
hard to get rid of (BLOCKs as abstract origin not so). And this isn't
stage1 material anymore I fear.
