It can handle linking dwarf debug info. Also I misspoke, you can't get dwarf debug info with clang-cl, but you can with clang++ on windows. Look at how the test suite on windows compiles the inferiors. That's currently the best debugging experience of Windows programs.
Unfortunately i was never able to get the rest of windows support implemented as i got pulled off to add support for writing codeview/pdb to clang-cl On Wed, Jul 26, 2017 at 5:38 PM Vadim Chugunov <vadi...@gmail.com> wrote: > Why -fuse-ld=lld?
