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.
