LLVM/Clang/LLDB/LLD
本节内容来自 LLVM Weekly 第 442 期, Alex Bradbury 大哥持续稳定输出。
想去x1: The June Women in Compilers and Tools meetup will feature Angélica Moreira presenting "Static profiling: why should you try it?".
想去x2: The LLVM Bay Area meetups are restarting, with the first to take place on July 11th. RSVPing is recommended.
想去x3: The 2022 Clang-Built Linux Meetup will take place in Dublin, Ireland on September 10th-11th. Registration is now open.
还在讨论啊…… Tanya Lattner (on behalf of the LLVM Foundation Board of Directors) posted a response to the move to Discourse retrospective, addressing the feedback collected during that exercise.
估计很快可以订阅所有会议了: Kristof Beyls announced that an LLVM community events calendar has been created, aiming to include all online sync-ups, office hours, meetups, etc.
学习: Nikita Popov proposed removing most constant expressions in LLVM IR. Initial response has been positive about this direction. Chris Lattner also provided some historical perspective on pointer types in LLVM IR.
好像很久没有JIT的weekly了? LLVM GPU News #36 is out.
可能AI编译器有关? bf16 is now promoted to f32 when the target doesn't support it. fb34d53.
Hello libc! An entrypoint for LLVM libc's printf was added, allowing a "hello world" program with just LLVM-libc to be built. ad233c6.
诶,大事件? A generic data-flow analysis framework was added to MLIR. ead75d9.

本周推荐:《还是要相信》
作者: 陈鲁豫
推荐: 小编1号
这本书尚未翻开就带给我两大震撼:首先看封面的照片我是没看出来这是鲁豫;其次,原来鲁豫不是姓鲁,而是姓陈。书名也明显是呼应我微信常用表情包「真的么?我不信」的梗。幽默感已经外溢了。
里面的内容是比较轻松的,适合轻松的时候阅读,鲁豫自己记录下来的一些事情的看法和自己的生活的感悟。挺好的,整体上不偏激,正面积极。
还是要相信,电视媒体和平面媒体(书本)呈现的是完全不一样的感受。
