I don't know.  =/

All my bytecode files are built for:

	target datalayout = "e-p:32:32"
	target endian = little
	target pointersize = 32
	target triple = "i386-portbld-freebsd7.0"

Build a small bytecode file on your end, disassemble it, and compare.
(llvm-dis < yourfile.o | head -5)

LLVMers, given the same endianness and pointersize, can one mix and
match LLVM bytecode files produced on different platforms?
