LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第 568 期， Alex Bradbury 大哥持续稳定输出。

• 宋教授！ MaskRay blogged about removing global state from LLD.

• 没看懂在干啥： Neil Henning wrote up work to add custom runtime togglable asserts in an otherwise unmodified LLVM codebase.

• 赞美！ Stefanos Baziotis wrote a high level overview of some common compiler optimisations.

• 参考： The MLIR and LLVM related activities at SC'24 are summarised here.

• David Spickett shared news of the major usability improvement now implemented through better test result reporting of Buildkite pre-commit checks. Thank you David!

• 啊？这个还需要讨论？ James Y Knight kicked off a discussion on C calling convention lowering to LLVM IR.

• 国内有伙伴在做LLVM的buildbot么？OSDT大会上交流下？ Alex Bradbury shared a PSA on recent improvements to llvm-zorg buildbot configuration testing. Specifically, there's now a documented and working flow that allows you to test a builder locally before submitting to llvm-zorg, and llvm-zorg now has precommit checks via GitHub Actions using this.

• 好用： lit gained a --report-failures-only option to only list failures in the XUnit XML test report. c63e83f.

• 有RISC-V了： LLVM Offload now has minimal support for riscv64 in its host plugin. b6bd747.
