At this time, LLVM is known to correctly compile and run all C &amp; C++ SPEC
CPU2000 benchmarks, the Olden benchmarks, and the Ptrdist benchmarks. It has
also been used to compile <b>many</b> other programs. LLVM now also works with
a broad variety of C++ programs, though it has still received less testing than
the C front-end.
