With LTO we somehow decided we can do (insn 2 3 4 2 (set (subreg:DI (reg:V2SF 61) 0) (reg:DI 21 xmm0 [ x ])) 20050316-2.c:17 -1 (nil)) but without we go through the stack. I'm sure our option-replay code is at fault, but if it is then possibly there exists a user command-line option that triggers this without LTO.
