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 haveopen 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 aboutusability improvements in GCC 15.
热烈讨论中： "Sirraide" proposedmaking-Wreturn-typean error by default in Clang. Aaron Ballmansummarised follow-up discussion in a meetingwhere 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-Whardenedoption could be introduced which opts into stronger diagnostic behaviour.
期待 RISC-V + UEFI + libc： Tristan Ross proposedadding UEFI platform support to LLVM libc.
开会时间调整： Alex Zinenko islooking to rearrange some upcoming Open MLIR meeting time slotsand seeking input.
收藏： Slides weremade 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 islooking 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.
