- a mailing list,
- a blog article with examples,
- the article "A performance update" that describes, how LLVM can improve performance
Additional stuff

ifThenElse,whileLoop,Maybe), vector instructions, automatic adaption to target specific extensions
Applications
- synthesizer-llvm provides efficient signal processing using vector instructions, including a realtime software synthesizer
