Regression from 4.5. Eventually the assert was just added ...

Yep. r189974.
Looks like the target is confused by building a -fshort-double V2DF with
using double_type_node.
Probably broken also on i?86, just not triggered.
OTOH, -fshort-double is a red herring ...

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r189974, but that is just because it added an assertion.
The question is, if -fshort-double really has to be supported on x86_64/i686
(as ABI changing option), what to do with the intrinsics, grep double
config/i386/*intrin*.h shows quite a lot of intrinsics that use double, and
various builtins really assume DFmode arguments/return values/V*DF vectors etc.
So, perhaps we could just override
ix86_builtin_type_tab[(int)IX86_BT_DOUBLE] if double_type_node doesn't have
DFmode TYPE_MODE to some DFmode REAL_TYPE (that would likely fix this ICE), and
perhaps tweak the *intrin*.h headers to use typedef double __real_double
__attribute__((__mode__(__DFmode__))); instead of double (perhaps not this
part, it will very unlikely do the right thing, perhaps just tell people not to
use the intrinsics).

I'm seeing the same ICE on i386-pc-solaris2.1[01] as of r209079. I suppose the
test needs to be skipped on that combination, too.

Should we just disable the option? If it hasn't worked since 4.5 probably noone
needs it.

IMHO -fshort-double should be made a target specific option and generally not
supported.
