A quick update on our large dataset of LLVM intermediate representation - we have published the full dataset on HuggingFace datasets by now (huggingface.co/datasets/llvm…) with more work to come in the near future :) We've also revised the preprint: arxiv.org/abs/2309.15432

For a friend: A certain national lab in Illinois decided to mess with their employee medical benefits. (With no consultation and 1 month lead time). If you were looking to poach some great #HPC people, now is probably an ideal time.
