GCC
重要的一步终于迈出 RISC-V: Public review for Non-ISA Specification: psABI https://gcc.gnu.org/pipermail/gcc/2022-July/239091.html
[PATCH] arm: add -static-pie support https://gcc.gnu.org/pipermail/gcc-patches/2022-July/598573.html
一步一个脚印,LoongArch的将来会更好 [PATCH v1 0/2] LoongArch: Modify the method of obtaining symbolic addresses. https://gcc.gnu.org/pipermail/gcc-patches/2022-July/598545.html
[PATCH] Revert "[PATCH] RISC-V: Use new linker emulations for glibc ABI." https://gcc.gnu.org/pipermail/gcc-patches/2022-July/598430.html
[PATCH 0/1 V4] RISC-V: Support Zmmul extension https://gcc.gnu.org/pipermail/gcc-patches/2022-July/598205.html Zmmul是RISC-V技术委员会今年批准的第一个ISA相关的SPEC,实现不带除法的m extension,设计的初衷参见: “For many microcontroller applications, division operations are too infrequent to justify the cost of divider hardware, the RISC-V Zmmul extension will benefit simple FPGA soft cores in particular.”
Binutils/GDB

GLIBC
GLIBC社区的 patch review meeting 真好,大大加快patch合入的速度 Monday Patch Queue Review update (2022-07-18) https://sourceware.org/pipermail/libc-alpha/2022-July/140788.html
[PATCH v7 00/13] GLIBC LoongArch PATCHES, almost there! https://sourceware.org/pipermail/libc-alpha/2022-July/140794.html
LLVM/Clang/LLDB/LLD
本节内容来自 LLVM Weekly 第 446 期, Alex Bradbury 大哥持续稳定输出。
这是啥?不知道: What LLVM merchandise would you like to see? Take part in the survey.
收藏收藏: Another talk from EuroLLVM is now available (I believe the final one). Jan Svoboda presents "Implicitly discovered, explicitly built Clang modules".
LLVM 15 要来了么: As a reminder, LLVM 15.x will branch on July 26th.
诶? The first meeting about creating an MLIR based Clang IR will take place on Friday July 22nd.
修了好几次了? Stella Laurenzo provided detailed notes on the recent MLIR C/Python API registration overhaul.
有用么? Kazu Hirata proposed deprecating
llvm::Optional<X>::hasValue/getValue/getValueOr, instead recommending the use ofhas_value/value/value_orwhich matches thestd::optionalinterface.终于! Kito Cheng shared that the RISC-V psABI public review period has now started.
做C++前端估计头大: Sheng posted an RFC focused on implementing C++20 P0960R3, for initialising aggregated with a parenthesised list of values.
龙芯加油: LoongArch codegen functionality was further expanded, with support for FP conversions and atomics. 1df96ce, e147a0f, 47f3dc6.
Topper太勤勉了: A RISC-V specific CodeGenPrepare pass was added, looking for opportunities for replacing zero-extension with sign-extension on RV64. 1a8468b.

本周推荐:《激荡三十年:中国企业1978-2008》
作者: 吴晓波
推荐: 小编1号
几年前,小编一号离开了校园,开始直面社会以及自己未来短暂的生命的时候,产生了在文明尺度下自己生命和价值之渺小的恐慌。于是开始大量的阅读历史人物的传记、阅读不过的学者写的世界史,尝试将自己的生命和更为久远的文明联系起来。而另一方面我又热衷于去寻找历史中人物的细节,没想到一个朝代,就问那个时代,成年人如何上厕所、小孩子如果肠套叠能否有的救、眼睛近视了能否有眼镜可以戴,诸如此类的细碎生活。就像是想要有短暂的一生去过好多人的一辈子。何其的贪心呐。
《激荡三十年》是满足了我的贪心的非常好的作品。即便身为创业者我已经对书中多数人物的故事有所了解,吴晓波在书中展示的细节,大量的不经意的细节,总是让我在没有防备的地方突然情绪涌上来。
即便你不是创业者、也没有成为企业主的念头,这本书中描写到的企业家和他们的企业也一定能够在某些时刻进入过你的生活 —— 甚至刷满了你家的外墙 —— 用那个年代特别狂野的方式。
