Hi, sorry for the late reply.
This certainly looks interesting (I just glanced over it so far), but I
guess for Eigen this could only serve as "inspiration" for better code,
since we need to stay compiler-independent.
At the moment, I don't think making different code-paths just to support
this, is a good idea. Although, eventually this could be handled like a
different "architecture".
Cheers,
Christoph

Hello,
As already mentioned earlier on the list, we recently shared a proposal to add support for some matrix math operations to Clang.
The extension initially helps to improve & simplify code generation for small matrixes (sizes < 15x15). We are currently trying to make sure the extension is useful for a wider range of users. It would be great if you could take a look and share any feedback or comments on cfe-dev.
The original proposal can be found on the cfe-dev mailing list: http://lists.llvm.org/pipermail/cfe-dev/2019-December/064141.html <http://lists.llvm.org/pipermail/cfe-dev/2019-December/064141.html> and the thread continues in January: http://lists.llvm.org/pipermail/cfe-dev/2020-January/064206.html <http://lists.llvm.org/pipermail/cfe-dev/2020-January/064206.html>
The original proposal uses builtins for matrix operations, but as part of the initial feedback we are planning on replacing those with proper operators for the type.
Thanks,
Florian
