115 Engine. This will make the code run considerably faster on Cell
116 but somewhat slower on other machines. This option only changes
117 the scheduling of instructions, not the selection of instructions
118 itself, so the resulting kernel will keep running on all other
119 machines. When building a kernel that is supposed to run only
120 on Cell, you should also select the POWER4_ONLY option.
