David,
Thanks for the information. Since FSF gcc on darwin is unlikely
to gain LTO any time soon (unless it comes in the form of DragonEgg
http://dragonegg.llvm.org/), I was hoping that we might realize
some performnce improvements via graphite (or at least see that
the none of the Polyhedron 2005 benchmarks degrade under its
optimizations) in gcc 4.5.
