For windows we have Portable Executable (PE) as the container format. This implies that the DWARF work is (unsurprisingly) completely inapplicable for Windows. It's not quite as simple. Dwarf info can be embedded into windows executables/libraries. Tools that understand dwarf can read that information and use it. However many tools on windows don't understand dwarf debugging information since windows has it's own debugging format.
So it's not quite as helpful as on linux where everyone agreed to use dwarf. But it still can be used for some things. E.g. there are debuggers on windows (lldbg, gdb) that can read and use this information. Further we could in theory start emitting the same information in the windows native format. In that case we could re-use much of the work that went into GHC to allows us to collect debugging information. Putting into the right format comes fairly late in the pipeline and all steps up to that could be shared. Cheers Andreas
