Changes in directory llvm/lib/CodeGen/SelectionDAG:
LegalizeDAG.cpp updated: 1.482 -> 1.483
---
Log message:
big endian 32-bit systems (e.g. ppc32) want to return the high reg first, not
the lo-reg first. This is fallout from my ppc calling conv change yesterday,
it fixes test/ExecutionEngine/2003-05-06-LivenessClobber.llx
