This library implements a backend for the /Accelerate/ language which

package.

[/Dependencies/]

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

* <http://llvm.org LLVM>

* <https://developer.nvidia.com/cuda-downloads CUDA>

[/Installing LLVM/]

/Homebrew/

Example using Homebrew on macOS:

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

/Debian & Ubuntu/

For Debian/Ubuntu based Linux distributions, the LLVM.org website provides
binary distribution packages. Check <http://apt.llvm.org apt.llvm.org> 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
<http://releases.llvm.org/4.0.0/docs/CMake.html LLVM.org>. 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. 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:

> flags:
>   llvm-hs:
>     shared-llvm: true

Or by specifying the @shared-llvm@ flag to cabal:

> cabal install llvm-hs -fshared-llvm
