Cell Broadband Engine (Playstation 3)

Don't use -mcpu=970 it will make the PS3 slower due to the different pipeline (after all it is a CELL B.E and not a G5). GCC 4.3 or SDK 2.1+ is recommended. A second hint: Unlike x86-64 architecture, it is better to use 32bit user land on a PowerPC with a 64bit kernel. The benefit is, that pointers are 32bits so memory usage goes down slightly. In fact unlike x86_64, the number of registers don't change and the register size does not change (though the Linux kernel has issues with interrupts) and the kernel will save all 64bits of the register across context switches.
