本节内容来自 LLVM Weekly 第 561 期， Alex Bradbury 大哥持续稳定输出。

• 有意思： Joseph Huber has a rather neat port of Doom that runs on AMDGPU with ROCm and LLVM's libc.

• 感谢撰写入门文档： James Hamilton provided a high level introduction to LLVM.

• 请大家多多讨论： Chris Bieneman provided an update on efforts to establish a new LLVM project governance model, noting the hope to conduct the first elections in January 2025 if the proposal is adopted.

• 国内有企业在关注这个话题么？好像开发者一般用的都是比较高的版本： Erich Keane posted an RFC on updating the supported host compiler versions for LLVM 20. A large chunk of the ensuing discussion was about the expectations for whether builds should be -Werror-clean on all supported toolchains or not (they're not today), though it was agreed this discussion belongs in a separate RFC.

• 推荐看看： Nikita Popov suggested improvements to capture tracking in LLVM.

• 收藏： Anton Korebeynikov provided a detailed update on pointer authentication support as of the LLVM 19 release as well as listing work that is still in progress.

• David Blaikie proposed a tweak to LLVM's header including policy. Some respondents were keen to ensure the policy isn't interpreted in a way that suggests running include-what-you-use is required.

• 能行？ Rahul Joshi proposed support for auto in TableGen and also shared recent improvements to formatting/printing helpers in LLVM.

• 注意⚠️： Donald Chen shared a PSA about the semantics of program points in MLIR dataflow analysis changing.

• 变简单了： LLVM's release notes are now in Markdown rather than RST. b9f09a4.

• 更好用了？ An llvm.atan2.* intrinsic was added. 26029d7.

• 恭喜： The Zacas RISC-V extension is no longer marked as experimental. 614aeda.

• 可以试试了： Command-line options were introduced for RISC-V CFI. 9f33eb8.

• MLIR gained support for LLVM operand bundles. fde3c16.

• 假期搓一个？ Documentation on adding support for a new language was added back to LLDB. a3cf01d.

• 更加美观： Errors from LLDB's inline expression evaluator are now much prettier. d33fa70.
