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.
Jack
