      LLVM​

      本周合并了以下的功能改进等：

      • tangyouling、Ami-zhang 为 compiler-rt fuzzer 组件适配了非 4KiB 页的系统。当然，也包括龙架构。

      出现了以下的新动向：

      • xen0n 终于找到了足够时间调试并修复了 lld/ELF LoongArch port 的 TLS 处理逻辑。该补丁终于称得上「完成」了。

      Rust​

      添加龙架构裸机 targets 的 MCP 正在公示期内。目前没有反对意见，预计本周将获得通过。

      龙架构 Rust 维护者们也在着手为 rustup 添加支持了：

      截至发稿时，这些 PRs 都已被合并。 预计到 Rust 1.71.0 正式发布时，龙架构 Rust 开发者将得以享受不逊其他架构的同等开发体验。

      AOSCC 2023：7 月 15 至 16 日，上科大见！​

      距离今年 AOSCC 还有不到一个月，本次聚会的日程繁多，不仅有社区项目相关的展示、讨论和投票，还有许多来自开源业界的代表门将会到场分享经验，回答问题。

      详见：活动日程。

      “龙芯与你：你问我答”问题征集​

      近年来，由 LoongArch 架构驱动的龙芯 5000 系列处理器展现出了相当可观的性能提升，亦在开源社区中收获了不少人气；与此同时，企业与社区的“新旧世界”交替与在上游的碰撞与交流也成为了最近几年 LoongArch 生态参与者们时刻关注的事情。本次 AOSCC 我们有幸邀请到了来自 LoongArch 社区的上游贡献者和龙芯中科的工程师们来一同介绍和解答各位的问题和疑惑。

      考虑到日程安排较为紧凑，我们决定提前收集社区提问，请使用本问卷提交您希望得到解答的问题。

      与会者登记​

      由于本次 AOSCC 线下活动在上海科技大学举行，校方安保要求来访者登记个人信息，有意参加线下活动的，请于 7 月 13 日前填写登记问卷。

      说明

      本表格仅由社区代表（白铭骢）和 GeekPie 对接代表（秦斐然）查阅，并交由校方录入。

        先前一直以为 .NET 7.0 里增加的那个支持能用，然而实际测试发现是旧世界 ABI，新世界上无法编译。主线代码直到 2023-09-20 才在新世界达到可用，这意味着 .NET 8.0 也已经被错过。如果要用，则需 backport 或等 .NET 9.0。
