|
+ 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
|
|
|
+ machines. When building a kernel that is supposed to run only
|
|
|
+ on Cell, you should also select the POWER4_ONLY option.
