The accelerate-llvm package

[ Tags: bsd3, compilers-interpreters, concurrency, data, library, parallelism ] [ Propose Tags ]

This library implements direct LLVM IR generation for the Accelerate language. For further information, refer to the main accelerate package.


Haskell dependencies are available from Hackage. The following external libraries are alse required:

Installing LLVM


Example using Homebrew on macOS:

brew install llvm-hs/homebrew-llvm/llvm-4.0

Debian & Ubuntu

For Debian/Ubuntu based Linux distributions, the website provides binary distribution packages. Check for instructions for adding the correct package database for your OS version, and then:

apt-get install llvm-4.0-dev

Building from source

If your OS does not have an appropriate LLVM distribution available, you can also build from source. Detailed build instructions are available on Make sure to include the cmake build options -DLLVM_BUILD_LLVM_DYLIB=ON -DLLVM_LINK_LLVM_DYLIB=ON so that the libLLVM shared library will be built.

If using the accelerate-llvm-ptx backend, also ensure that the LLVM_TARGETS_TO_BUILD option includes the NVPTX target (if not specified, all targets are built).

Installing accelerate-llvm

To use accelerate-llvm it is important that the llvm-hs package is installed against the libLLVM shared library, rather than statically linked, so that we can use LLVM from GHCi and Template Haskell. This is the default configuration, but you can also enforce this explicitly by adding the following to your stack.yaml file:

    shared-llvm: true

Or by specifying the shared-llvm flag to cabal:

cabal install llvm-hs -fshared-llvm

Enable debug tracing message flags. Note that debug must be enabled in the base accelerate package as well. See the accelerate package for usage and available options.


Enable bounds checking


Enable bounds checking in unsafe operations


Enable internal consistency checks


Use a Chase-Lev deque for work stealing


Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info


Note: This package has metadata revisions in the cabal description newer than included in the tarball. To unpack the package including the revisions, use 'cabal get'.
