[llvm-commits] CVS: llvm/lib/CodeGen/SelectionDAG/LegalizeDAG.cpp

[Chris Lattner]

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
