This is the third public release of the LLVM compiler infrastructure.

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

-The LLVM native code generators are very stable but do not currently support -unwinding (exception throwing or longjmping), which prevent them from -working with programs like the 253.perlbmk in SPEC CPU2000. The C -backend and the rest of LLVM supports these programs, so you can -still use LLVM with them. Support for unwinding will be added in a future -release. +received less testing than the C front-end.
