本节内容来自 LLVM Weekly 第 ❤️520❤️ 期, Alex Bradbury 大哥持续稳定输出。
好汇总: David Spickett wrote on the LLVM project blog about tools for learning LLVM TableGen.
张洪滨同学加油~: There was a really detailed discussion about a proposal from Hongbin Zhang and Diego Caballero to support dynamic vector semantics (e.g. RISC-V vectors) in the MLIR vector dialect. Check the thread out for thoughts on the trade-offs of adding increasingly more types vs extending the functionality of the existing ones, specific challenges of dynamic vector types, whether to mirror LLVM's RVV representation, and more.
有意思: Johannes Doerfert shared both a llvm-project/offload roadmap and an example of portable CUDA offloading (running a CUDA kernel on an AMD GPU, falling back to CPU if not suitable GPU is found).
Intel 的 GPU 跑 GEMM: Jianhui Li proposed adding a XeGPU dialect for Intel GPUs.
或许得看看: Dayann D'almeida shared and update that an initial implementation of the llvm-cm (cost model evalution tool) proposal is now available and will be iterated on until it's in a state it can be proposed for integration into the monorepo.
好几个buff叠加的新闻: Stella Laurenzo provided an update that ONNX import is now upstreamed into torch-mlir.
全世界做调试器的人还有可能坐满一间会议室么? Chelsea Cassanova proposed improving LLDB's progress reporting to allow it to provide better feedback on long-running operations.
BPF还是来了: GlobalISel support for the BPF backend was started. 2460bf2.
打开新优化机会的大门? ThinLTO can now import a workload definition. ed10fba.
掌声: Support was added for building LLVM's libc with scudo for riscv64. 2c0abdf.
奇妙的世界线开始缝合: LLVM's OpenMP library can now be compiled to WebAssembly. As noted in the commit message, this is just a starting point with more work to be done. 68ea91d.

本周推荐:《第七天》
作者:余华
推荐:小编1号
因为喜欢作者所以拿起了这本第七天。刚开始看觉得猎奇和意外,觉得挺有意思的。到中间的时候,有了一种奇怪的“真实”感,因为书中的道路旅行式的串联回忆会让70后80后准确的记忆起来很多社会新闻里的普通人。而能上新闻的普通人,大多是以意外和悲剧的形式。这种真实和虚幻的交叠感觉一直到最后,我明白了作者的意图,并让我感觉到了一种感动。每一个悲剧新闻中离开的人,都在死后的世界里得到了生命的延伸,达到了某种释然。
作为一个普通人,对于他人的苦难我们绝大多数时候都是无能为力的。而作者说,或许,至少我可以给他们创造一个幸福一点的结局。
