  • 得看看： Nikita Popov made a proposal, 'yet another strict FP'. "I believe that if we want to improve on the current strict FP situation, and treat strict FP as more of a first class citizen, we need to avoid further half measures, and actually support first-class FP environment annotations on all floating-point operations, including basic FP instructions." This proposal was move the IR from something like %res = call float @llvm.experimental.constrained.fadd.f32(float %a, float %b, metadata !"round.dynamic", metadata !"fpexcept.strict") to %res = fadd float %a, %b fpenv(rounding_mode: dynamic, strict_except: true, ...).

  • 注意看看： The Project Council fed back on some RFCs, such as enforcing the rule of three and adding a non-blocking pre-commit clang-tidy bot.

  • 许传奇： ChuanqiXu suggested that C++20 modules serialisation tests be required for new features.

  • Arm 最近更新量很大： A new pass was added to the AArch64 backend for code layout optimisation, forcing 64-byte function alignment in certain cases and instruction alignment for some instruction pairs that may cross cache lines. 8996639.

  • 好久没有为win32开发过程序了： A bug was fixed where Clang over and under-aligned variables for Windows MSVC. 8ecec45.

本周推荐：《龙与洋鬼子：一位瑞典地质学家眼中的万象中国》

作者：安特生

译者：李雪涛

推荐：小编1号

最近微信读书推荐的民国的书籍变多了些，这本书的作者精力也是颇具“穿越”色彩。作为一个瑞典考古学家，来到了民国时期的中国，进行考虑，还受雇于北洋政府，跟袁世凯见过面。北京猿人、仰韶文化等发现都有作者的参与或主导。

所以阅读本书就时不时有一种年代缝合感，九年义务教育中已经忘记差不多的历史、地址、政治、语文知识，通过一个具体的老外考古学家串在了一起。
