本节内容来自 LLVM Weekly 第 647 期， Alex Bradbury 大哥持续稳定输出。

欢迎参加： The Beijing LLVM meetup will take place on May 29th and feature two RISC-V focused talks.
主持： Aaron Ballman is seeking to organise a testimonial to ISO on the importance of open access to ISO standards documents on behalf of the LLVM community. Per the timeline, please leave comments and recommended edits on the linked draft through to May 27th.
简化： Reid Kleckner proposed transitioning from reST to Markdown for LLVM documentation. There's a lot of support for this direction, but also some concerns about the churn, packaging issues, and the volume of existing reST documentation.
祝贺 Luke！ Luke Lau shares that lnt.llvm.org is now tracking RISC-V performance for clang and GCC. Now that the official LLVM-hosted LNT instance is back up, reporting has moved from Igalia's instance. Even more importantly, Luke gives a really great quick start guide on how to navigate the web interface and interpret the results.
感觉可能是个深远的变化？ Varad Rahul Kamthe posted an RFC on supporting default arguments in LLVM intrinsics as a way to help avoid breaking changes when new arguments are added to intrinsics.
日积跬步： 32-bit RISC-V support was added to BOLT. ce002b2.
欢迎 FreeBSD，最近一年看接触到了更多的 FreeBSD 伙伴： Initial FreeBSD support was added to LLVM's libc. 633539b.

往期社招及实习生招聘长期有效。
