[LLVMdev] llvm LTO SPEC2000 results?

[Jack Howarth]

   Are there any results for the SPEC2000 benchmarks
using llvm with and without LTO? It would be interesting
to know how the current LTO in llvm compares to the
results being seen in current gcc trunk with their
LTO...

It would appear that the gcc LTO implementation
is finally showing results (although with a lot
of wrong code results). I assume we really don't
have a functional -fwhole-program in llvm-gcc-4.2
but do we have one in clang?
