+       (record_reg_classes): Cope with a prefclass set to NO_REGS.
+       * reload.c (find_reloads): Take PREFERRED_OUTPUT_RELOAD_CLASS
+       into account.  For non-registers, equate an empty preferred
+       reload class to a `!' in the constraint; move the if clause to
+       do so after those that reject the insn.

+       return NO_REGS.
+       (find_dummy_reload): Likewise.
+       * doc/tm.texi (Register Classes): Document what it means
+       if PREFERRED_*_RELOAD_CLASS return NO_REGS.
+       * config/i386/i386.c (ix86_preferred_reload_class): Force
+       using SSE registers (and return NO_REGS for floating-point
