关于src-openeuler构建代码仓中适配RISC-V 所做修改的代码管理策略说明
by zhangxuzhou 14 Sep '20

14 Sep '20

各位专家，TC委员大家好：在进行RISC-V架构的移植过程中，涉及到适配RISC-V所做的代码修改和如何提交的问题；经过在release-management 社区进行issue讨论（点击查看）<https://gitee.com/openeuler/release-management/issues/I1TSRP?from=project-i…>，给出一个对于RISC-V相关的代码管理策略，想听取各位的意见： 1．优先“共主线”原则，即涉及到适配RISC-V所做的修改在不影响openEuler master版本的情况下，推送代码仓的master分支； 2．若无法共主线（如master版本暂时无法升级，需回合大量补丁影响master稳定等），则新建立分支，并统一命名为“riscv”，方便在未来进行openEuler RISC-V版本构建时统一拉取分支； 3．对于2中所述的情况，在master版本可收编时，及时收编 riscv 分支，保持共主线原则；麻烦各位专家委员协助审视反馈策略是否需要改进。 Best Regards! 张旭舟华为技术有限公司 [cid:image002.png@01D6674C.23784BB0]

1．回顾上周的工作，这一阶段优化同步到openEuler社区的工作已经完成 2． glibc库编译失败，可能原因是gcc的优化导致，目前提交了一个修复补丁，解决部分问题，但glibc包整体上依然编译失败，需要支持解决会上Eric（ARM）提了几个问题： 1． https://gcc.gnu.org/pipermail/gcc-patches/2020-June/546950.html gcc社区原生的问题，会影响HPC场景的编译，ARM的同事Wilco提了一些意见，建议通过修改abi的方式实现，会后我们需要看下基于这个思路如何实现 2．关于Compiler SIG在JDK/GCC上的优化后续upstream的讨论会后和ARM公司的简宁胜做了交流，在OpenJDK上SVE指令的支持进行分工合作，ARM的同事将投入Vector API mask对SVE的支持，Compiler SIG的同事在vector api SVE backend剩余OP的支持工作上进行投入发件人: Meeting Book [mailto:uMeeting@huawei.com] 发送时间: 2020年9月7日 11:25 收件人: dev(a)openeuler.org 主题: [Dev] 【Meeting Notice】Compiler SIG weekly meeting Time: 2020-09-08 10:00-11:00 Topic Compiler SIG weekly meeting Time 2020-09-08 10:00-11:00((UTC+08:00)Beijing) Join Conference Join (External) >><https://welink-meeting.zoom.us/j/162757639> Meeting ID 162 757 639 Convener 郭歌 Tips: Dial the access number to join conference<http://app.huawei.com/eshare/voiceMeetings> 注：仅支持部分国家和地区。( Only some countries and regions are supported.) 如果加入会议提示“会议已结束或会议号不存在”，请在官网下载最新版本入会。立即下载<https://zoom.us/download> If a message is displayed, indicating that the meeting has ended or the meeting ID does not exist, download the latest meeting client and try again.Download<https://zoom.us/download>

你好，目前openEuler的主干以及20.03版本都已经升级到10.0.1了，但是补丁还没有发布，待补丁发布后，预期可以在 http://repo.openeuler.org/openEuler-20.03-LTS/update/aarch64/Packages/ 下面看到供升级的包（也有可能有别的提供方式，比如在sp版本中提供，这个要看release-management SIG的安排）对于将llvm升级到11.0.0版本，我认为现在还不是最好的时机，因为11.0.0版本社区实际上还没有发布最终正式版本，目前只有rc版本，请见 http://llvm.org/，我们会在社区发布final版本的时候升级至最新版本我们致力于为openEuler社区提供【最具竞争力的】【稳定版本】，对于一些包我们会保持活跃的开发态，和上游社区的开发状态保持一致，但llvm目前还不在此列祝好发件人: 妞妞乖乖妈妈 [mailto:jeremiah.shi@qq.com] 发送时间: 2020年9月8日 7:49 收件人: guoge (A) <guoge1(a)huawei.com> 抄送: Zhanghaijian (A) <z.zhanghaijian(a)huawei.com>; liuzhiqiang (I) <liuzhiqiang26(a)huawei.com>; 502874763 <502874763(a)qq.com> 主题: Re: 答复: Clang在openeuler编译，求助亲爱的郭歌@jdkboy，早上好，我在openEuler 20.03 TLS everything 的安装还需要再更新一下安装库。昨天在Ubuntu 20.4环境下，已经部署成功了 Clang 10.0.0.4. 近期我在关注Clang code static Anayzer. 如果能OpenEuler上升级到Clang 10.0.0.X，也是很不错的：）在社区里，我找到了源代码包：clang-10.0.1.src.tar，没有能够编译成功。这方面，还请教您，看看可不可以在移植到openEuler上，我们保持好一点的成绩。从Mac OS 10.15来看，Apple的成绩是 Clang 11.X. 亟盼佳音：） Shalom Anno Domini 2020-09-08-7:48 jeremiah@jeremiah-VirtualBox:~/Desktop$ sudo aptitude install clang sudo: aptitude: command not found jeremiah@jeremiah-VirtualBox:~/Desktop$ ps aux | grep -i apt root 2655 0.4 1.1 196788 90764 ?
