LLVM is an abbreviation of "Low Level Virtual Machine"; LLVM is:
- A compilation strategy
- A virtual instruction set
- A compiler infrastructure
It is developed by the University of Illinois. It is implemented on many platforms, amongst others the iPhone.
You can use this from a Haskell program using essentially two bindings:
A strongly typed interface that is mainly intended to accelerate your Haskell programs with low-level code:
- llvm-tf, llvm-ffi
- a darcs repository,
- a blog article with examples,
- the article "A performance update" that describes, how LLVM can improve performance
- llvm-extra provides high-level control structures (
ifThenElse,whileLoop,Maybe), vector instructions, automatic adaption to target specific extensions - knead provides array processing similar to accelerate
- Example applications:
- synthesizer-llvm provides efficient signal processing using vector instructions, including a live software synthesizer
- patch-image constructs a big image from overlapping parts
An untyped interface mainly intended to write compilers and analyse LLVM bitcode:
