Fixing it all properly means some fairly significant architectural changes, and dropping the via-C backend
oh, thank you. from my POV, C backend still may be used together with "non-registerized" compilers. in particular, i hope that win-x64 will be supported at least in this way
noone asked my question about plans of win-x64 support. it's important for my users, so i ask you again - can you please implement it?
to other GHC users: i'm pretty sure that win-x64 support will not be implemented if it's required only for me. so, if someone need it - please write about this to ghc debelopers
It'll get implemented when (a) there is a working mingw64, and (b) it is important enough to enough people. As I understand it, (a) is getting closer, but there's still no official release. My guess is that it's a couple of weeks' work. Win64 is quite different from the x86-64 Unix ABI: the calling convention is different, which means that all the FFI stuff has to be ported (the NCG foreign call support, GHCi foreign calls, rts/Adjustor.c). It took me a few days to get these working for x86-64 on Unix. What's more, while x86-64 on Unix is nicer in many ways than the 32-bit ABI, Win64 is significantly more horrible than Win32 (just MHO based on memories of reading a couple of MSDN articles), so I don't expect it to be a very enjoyable couple of weeks work :) Cheers, Simon
