Re: [Haskell-cafe] Global Arrays

Is there any proof of this? I'm not familiar enough with core to check. On Mon, Mar 12, 2012 at 3:48 AM, Ketil Malde wrote:

In Haskell, what's the canonical way of declaring a top-level array (Data.Vector of a huge list of doubles, in my case)? Performance is key in my case.

The straightforward way would just be something like:

globalArray :: V.Vector Double globalArray = V.fromList [ huge list of doubles ] {-# NOINLINE globalArray #-}

However, I don't want to have to run the fromList at runtime.

I think GHC will convert it to an array (and in general evaluate constants) at compile time (probably requires -O).
