Hi @browneee, I'm the co-author of this patch. Thanks for your comments.

> Who will use DFSan on loongarch64?

Currently nobody uses it as loongarch is a pretty new arch which is expected to graduate from experimental before llvm 16 release. (But I think there may be potential users of DFSan in future.) The motivation of this change is to make loongarch64 support as more compiler-rt components as possible. We notice that DFSan is a work in progress <https://clang.llvm.org/docs/DataFlowSanitizer.html#current-status>, currently under development for x86_64 Linux. So maybe we can defer the change until DFSan development is finished and there is a use case on loongarch64?

Loongson (https://www.loongson.cn/EN) can maintain it.

Yes, there is one: https://lab.llvm.org/staging/#/builders/236.
