Check for architectures that don't support unaligned reads?

[oberblastmeister]

I think there are some unaligned reads here, and some architectures don't support them.

Do you know perhaps how to check for architectures? I searched just now and didn't find out.

It makes sense to do it, but I'd consider it very low priority. Backends without unaligned access are extremely niche. Some searching turned up SPARC as the only such official backend.

bytestring does this https://github.com/haskell/bytestring/blob/master/Data/ByteString/Short/Internal.hs#L22

Thanks!

GHC 9.10 will be coming with (read|write)Word8OffAddrAs<ty> primops, which will handle unalignment on platforms that don't support it! (This isn't news to oberblastmeister because they wrote it! but I only just learned and it's gonna be super handy for some of my own code! thanks!!)
