Host platform

determineHostPlatform :: IO (Maybe Platform)

Determine the default host platform.

Uses the arch and uname commands which must be in the current path.

Returns Nothing if arch or uname cannot be found, returned an error, or we didn't recognise their response.

For Platforms like Darwin which can run both 32-bit and 64-bit binaries, we return whatever the default is reported by arch and uname.

determineHostArch :: IO (Maybe Arch)

Determine the host archicture. Uses the arch command which must be in the current path.

determineHostOs :: IO (Maybe Os)

Determine the host OS. Uses the uname command which must be in the current path.

determineHostLlvmVersion :: Maybe FilePath -> IO (Maybe String)

Determine the host LLVM version string, eg "3.5.2" Takes the path to the LLVM compiler to use, or Nothing to use whatever is in the current path.
