118 Cause the compiler to optimize for the PPE of the Cell Broadband
119 Engine. This will make the code run considerably faster on Cell
120 but somewhat slower on other machines. This option only changes
121 the scheduling of instructions, not the selection of instructions
122 itself, so the resulting kernel will keep running on all other
123 machines. When building a kernel that is supposed to run only
124 on Cell, you should also select the POWER4_ONLY option.
