--- Comment #1 from Andrew Stubbs <ams at gcc dot gnu.org> ---
GCN uses TImode for a few special purposes, but lacks real TImode support.

(Basically, it allows TImode loads and stores for the SLP fake vectorizatio=
n,
and there's one instruction that needs two DImode values in consecutive
registers.)

Probably this is a GCN-specific issue, and we should be finding another way=
 to
handle the quasi-128-bit values.=
