Extended Description

Currently, lld/COFF completely ignores /align option. That option is not required for building regular programs, but some programs such as device drivers needs it.

We need to handle that option correctly.

Steven,

I created a patch for you. If you can build lld locally, can you apply this patch and try to see if this would fix your issue? https://reviews.llvm.org/D65736
