LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第 589 期， Alex Bradbury 大哥持续稳定输出。

• 这个厉害了： Qualcomm have open sourced ELD, an embedded linker with support for AArch32/AArch64, Hexagon, and RISC-V.

• 看看： David Malcolm writes on the Red Hat Developer blog about usability improvements in GCC 15.

• 热烈讨论中： "Sirraide" proposed making -Wreturn-type an error by default in Clang. Aaron Ballman summarised follow-up discussion in a meeting where it was concluded that leaving it as warnin by default makes most sense (due to the possibility of false positives for this warning), but a new -Whardened option could be introduced which opts into stronger diagnostic behaviour.

• 期待 RISC-V + UEFI + libc： Tristan Ross proposed adding UEFI platform support to LLVM libc.

• 开会时间调整： Alex Zinenko is looking to rearrange some upcoming Open MLIR meeting time slots and seeking input.

• 收藏： Slides were made available from the recent Open MLIR meeting on an interaction nets dialect.

• 以前我也做过基本块统计： Joel E. Denny is looking for feedback on proposed efforts to maintain more accurate block frequencies, with the motivation of improving loop transformations.

• “只要活得足够久就能看到有生之年级别的更新” A scheduler model was added for the IBM z17 processor. 80267f8.

• 国内有接触Haiku的伙伴么？ Haiku support was added to the sanitizers. d1fd977.

• CIRCT 项目虽然话题性少了，但是一直在继续： The SMT dialect from the CIRCT project was upstreamed into MLIR. de67293.

QEMU (RISC-V)

• [PATCH 00/17] Implements RISC-V WorldGuard extension v0.4 https://lists.nongnu.org/archive/html/qemu-devel/2025-04/msg02141.html
