Last time I tested (which was a long while ago) there weren't any changes needed any more for 64 bit big endian powerpc - apart from 32 bit bool compatibility.

In case you've got a MacroAssembler implementation for some big endian architecture, you'd need the YARR JIT changes in order to make YARR JIT work correctly. I do have one for PPC OS X (ported from TenFourFox - Firefox port for PPC OS X) but I'll probably never be able to make it ready for getting committed. By the way I've also got the CSS selector JIT working with that MacroAssembler on PPC OS X.
