I attempted a similar thing based also on redstar's work:
Clang part: http://llvm.org/bugs/show_bug.cgi?id=18654
LLVM part: http://www.redstar.de/ldc/win64eh_all_20140201.diff (latest
version should be linked on http://redstar.de/)
AFAICT, the code is emitted, but is faulty.
Also, feel free to try my Driver code as well, which removes all the silly
InitHeaderSearch junk from the MinGW-w64 code path:
http://llvm.org/bugs/show_bug.cgi?id=18546
This needs tests so it can be submitted. But I have not found the time nor
interest to write these, although they should be simple enough.
Cheers,
Ruben
