It's difficult for the nix maintainers to validate changes for platforms which are not supported by rustc, including ensuring they don't immediately regress in support as part of other changes. I see that there is a PR up adding support to rustc for loongarch64-unknown-linux-gnu; this change is likely gated on that PR and until loongarch64-unknown-linux-gnu is supported as at least a Tier 3 target by the Rust compiler.

Once loongarch64-unknown-linux-gnu is supported as a Tier 3 target by rustc, I'd like to see it added to our CI pipeline as part of this PR, so we can ensure the support doesn't regress. #1603 is a good example of the changes needed. Note that it'd be added to the Tier 3 section of README.md, not Tier 1.

thank you very much for your suggestion, I have moved loongarch64-unknown-linux-gnu to the Tier 3 section of README.md

We will use loongarch64-unknown-linux-gnuf64 as the target name (see https://github.com/rust-lang/rust/pull/96971). AFAIK rustc doesn't have any "alias" support for target names so we can't use a plain loongarch64-unknown-linux-gnu.

And please just wait until rust-lang/rust#96971 is merged and released, otherwise the code here would be still useless at best, or require further changes if things change at the Rust side.

Thans for your review, i just rebase the code, I whill wait until https://github.com/rust-lang/rust/pull/96971 is merged and released

Ah, so an equivalent change was already merged in #2045. This can be safely closed then.
