7月15日截稿。

The 2020 Virtual LLVM Developers' Meeting call for papers is out, with a July 15th submission deadline. The Meeting has been moved to October 6-8 so as not to conflict with the Grace Hopper Conference.

开始学Python等社区了？

  • The first of the new "LLVM Proposals" format has been accepted, "LP001 Introduce a new LLVM process to resolve contentious decisions". As Review Manager, Chris Lattner summarised the feedback raised in the review.

本周安全性更新patch有点多？

  • An AArch64SLSHardeningPass was introduced to provide hardening for speculative execution across RET, BR, and BLR instructions. 0ee176e, c35ed40.

  • The LLVM coding standards documentation was updated to clarify that single-statement bodies of if/else/loop statements don't have braces. c08ea07.

  • FileCheck will now default to dumping input upon failure. d31c9e5.

  • Numerical expressions in FileCheck now allow calls to predefined functions. 8fd2270.

  • A lower complexity X86 Load Value Injection hardening pass was added for O0. 7e06cf0.

  • The X86 ASM parser can now harden inline assembly RET instructions against Load Value Injection. 0cbe713.

  • Clang static analyser now supports on-demand parsing of needed ASTs during cross translation unit analysis. 5cc1851.

  • LLVM's libc gained implementations of round[f], copysign[f], frexp[f], logb[f], and modf[f]. 4be1c11, 118c13c.

  • MLIR gained the skeleton of a SPIR-V to LLVM dialect conversion. fda5192.

本周推荐阅读

本周推荐：《上帝的图书馆》

作者: [美] 司各特·霍金斯

原作名: The Library at Mount Char

译者: 孙加

出版年: 2016-4-1

经由一位小伙伴推荐，拿起了这本书。一开始以为是鸡汤，后来没想到非常的刺激。故事是架空世界，如果灵魂只是脱离肉体进入了遗忘之地，而如果有人能够掌握知识将其召唤回来，那么，这个人是否就有了上帝的能力？原本是一位码农的作者，脑洞之大，让我读得非常的投入。当我翻到最后一个章节的时候，我已经基本上相信在美国是真的有一个这个地方了（手动狗头）。别的就不剧透了哈哈。

提示：有血腥、暴力等场景描写。
