描述

The CPU backend is currently broken on windows because it lacks an object file loader (here).

This is the same as what GHCi does, but a bit simpler because we only need to handle the most basic types of relocations etc. Unfortunately we can't use that one due to GHC#13624 (unless that does not affect windows, but I doubt it)

Any windows hackers interested in writing one? @RyanGlScott

研究方向
The primary file to modify is Data/Array/Accelerate/LLVM/Native/Link/COFF.hs (https://github.com/AccelerateHS/accelerate llvm/blob/master/accelerate llvm native/Data/Array/Accelerate/LLVM/Native/Link/COFF.hs). The issue requires implementing a COFF object file loader for Windows, similar to GHCi's loader but simpler. A known related issue is GHC#13624 which may affect the approach. Research should focus on Windows COFF format and relocations. The maintainer has expressed interest in a Windows hacker contributing.
