           Summary: VE backend tests fail on 32-bit x86

The following tests fail when LLVM is built with VE target enabled on 32-bit
x86 (well, 32-bit multilib of an amd64 system, to be more precise).  They pass
on a 64-bit system, so I suspect the backend code is not 32-bit friendly
somewhere.


Failed Tests (13):
  LLVM :: CodeGen/VE/Scalar/br_cc.ll
  LLVM :: CodeGen/VE/Scalar/cast.ll
  LLVM :: CodeGen/VE/Scalar/fcopysign.ll
  LLVM :: CodeGen/VE/Scalar/fp_add.ll
  LLVM :: CodeGen/VE/Scalar/fp_fneg.ll
  LLVM :: CodeGen/VE/Scalar/fp_mul.ll
  LLVM :: CodeGen/VE/Scalar/fp_sub.ll
  LLVM :: CodeGen/VE/Scalar/fp_to_int.ll
  LLVM :: CodeGen/VE/Scalar/select.ll
  LLVM :: CodeGen/VE/Scalar/shl.ll
  LLVM :: CodeGen/VE/Scalar/shr.ll
  LLVM :: CodeGen/VE/VELIntrinsics/vbrd.ll
  LLVM :: CodeGen/VE/Vector/insert_elt.ll


I'm attaching the complete build log in case it's helpful.  It includes all
build commands (both 32-bit and 64-bit), and the complete test suite output.
