--- Comment #6 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
So it seems to me that -ftree-coalesce-vars expects every GIMPLE register to be
mapped onto an RTL register if the type is returned in registers by the target,
but that's not true with BLKmode vector types on SPARC 64-bit. We may be able
to work around this during expand if there is an integer mode with the same
size as the vector type, but then we would need to add a new mode (OImode) for
SPARC.
Alexandre, any hint on the best course of action here?
