Looks like 7630 duplicate. We allow DImode in XMM and subreg DI->DF is actually the problem - we fail to reload DImode value to DFmode that is quite correct. Perhaps CLASS_CANNOT_CHANGE_MODE for FLOAT_REGS? I've raised the priority of the other bug, so I am keeping this medium http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=7897
