Hi everyone, the author is here. Yes, I believe the title should be changed to `Optimizing 128-bit Division`

Yet, I was not expecting it to be here. Overall, I put some knowledge hidden in Hacker's Delight book, Knuth, GMP and GNU in the article with my knowledge of low level optimizations. In the end it turned out to be a good thing to write and to submit into LLVM

What's the license? Hopefully, Boost or Boost compatible?

For compiler-rt it is Apache 2.0 license

Thank you. We've standardized on the Boost license for D, as it is the least restrictive, and well-accepted in the C++ community.

Is it possible you can make a Boost licensed version of it so we can add it to D?

That's a difficult question. As I am working at Google I need to consult each open source I want to publish on my behalf. This does not involve contributing to the list of the approved projects and telling about these contributions.

If you want to workaround this for now, I suggest looking into libdivide (https://github.com/ridiculousfish/libdivide), it is published with the boost license and the library contains all the needed artifacts I described in the article (unfortunately, not combined).
