你好，请问Loongarch64推进上游的进展怎么样了？目前的补丁可以直接用在3.22版本吗？谢谢！

3.22直接打3.20的补丁（来自loongarchlinux)编译报错：

已经同步到上游最新的代码，上游这几个版本忙于 FreeBSD 和 MacOS 系统，LoongArch 和 RISC-V 的审核计划都被搁置了。该仓库的 Valgrind 还未添加向量指令支持，所以在启用了向量支持的系统上是无法正常工作的。添加向量支持是一个非常大的工程，短期无法完善。

目前支持了 glibc 用到的向量指令，可以调试大部分非向量程序了。后续会先拿这个版本继续推上游，然后再考虑添加其余的向量指令。这个问题我先关闭了，有其他问题请另开。
