TODO: Works on: SPEC CPU 2000<p>
TODO: Works on: Olden/Ptrdist benchmarks<p>
The What's New section should give a bulletted list of what is
included, perhaps a couple of lists (Stable, Beta).<p>
It would be useful to give a pointer to a list of the available passes (at least
for the standard compiler techniques).<p>
At this time, LLVM is known to work properly with SPEC CPU 2000, the Olden
benchmarks, and the Ptrdist benchmarks among many other programs. Note however
that the Sparc and X86 backends do not currently support exception throwing or
long jumping. For these programs you must use the C backend.<p>
