As others have said, there is no similar instruction.

I think the problem is that you haven't fully set your compile environment
up to generate ppc code. It sounds like you are using a ppc assembler but
that the c compiler is still emmiting x86 assembly code (which of course
the ppc assembler doesn't understand). Or some assembly language fragment
is getting included, and the wrong one is being pulled in.

Good luck!

Take care,

Bill
