In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
Cause the compiler to optimize for the PPE of the Cell Broadband
Engine. This will make the code run considerably faster on Cell
but somewhat slower on other machines. This option only changes
the scheduling of instructions, not the selection of instructions
itself, so the resulting kernel will keep running on all other
