LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第 453 期， Alex Bradbury 大哥持续稳定输出。

• MLIR太火了： The MLIR Bay Area Developer Summit will now take place on November 10th, the day after the LLVM Developers' meeting.

• LLVM15开始准备： Tobias Hieta provided an update on the LLVM 15.0.0 release plans. At the time of writing, there are no open issues in the LLVM 15.0.0 release milestone on GitHub.

• Discussion within the thread on incubating the MLIR TCP dialect moved to more general comments about the status of the MLIR codebase and whether the incubator progress is always appropriate/required for new dialects. See e.g. responses from Chris Lattner, Stephen Neuendorffer, or Renato Golin.

• 这种讨论好像中国的伙伴一般都没参与？ Aaron Ballman created a thread about community code ownership in LLVM in general, which attracted many responses including detailed thoughts from Tanya Lattner.

• 宋老师回来了： Fangrui Song started a discussion on extending lit to support repeating a RUN line multiple time with different replacements, e.g. to make it easy to run the same test file on a range of C++ dialects in Clang.

• Emmmer同学稳定输出： Decode and emulation of further RISC-V instructions was added to LLDB. ff7b876.
