Re: [eigen] LLVM matrix math intrinsics

[David Tellenbach <david.tellenbach@xxxxxxxxxxxxx>]

Hi,

the discussion went on and the patch to add LLVM matrix intrinsics got committed: https://reviews.llvm.org/rG526244b187d23351056de6aba715dc3d44668b1c

This discussion about adding matrix support to the clang frontend explicitly references Eigen (and benchmarks against it), so though I'm going to share it: http://lists.llvm.org/pipermail/cfe-dev/2020-January/064371.html

Cheers,

David

Thanks for sharing, it will be interesting to follow where this is going.

Hi all,

just wanted to point you to an interesting proposal on the LLVM mailing list: Dedicated LLVM intrinsics for matrix math (http://lists.llvm.org/pipermail/llvm-dev/2019-October/136240.html). 

On Tuesday a first patch got into review, so this is relatively concrete: https://reviews.llvm.org/D70456. Eigen even got mentioned here: https://reviews.llvm.org/D70456#inline-635182

Cheers,

David
