Please provide standalone installers for sparc64-unknown-linux-gnu

[glaubitz]

With the progress made in the past months, the Rust compiler is now stable enough on Linux/sparc64 that it can be used to build projects like cargo and thundbird (version 58 with Rust code).

I would therefore like to ask to provide standalone installers for sparc64-unknown-linux-gnu on the download page "Other Installation Methods" (https://www.rust-lang.org/en-US/other-installers.html).

See https://doc.rust-lang.org/nightly/rustc/target-tier-policy.html for the policy on adding new targets.

My understanding is the linux builders have a bit of spare capacity, so that shouldn't be a blocker if we cross-compile from linux to sparc.

Hi @glaubitz, are you still interested in having a standalone installer? If not I'm planning to close this issue in the next month or so.

Yes, please. I'm currently having to build these manually for each Rust release in Gentoo.

Got it. It looks like sparc64-linux-gnu is currently a tier 2 target: https://doc.rust-lang.org/nightly/rustc/platform-support.html?highlight=sparc64-unknown-linux#tier-2
but https://forge.rust-lang.org/infra/other-installation-methods.html#standalone-installers only lists "tier 2 targets with host tools" (i.e. targets that have rustc available, excluding targets that only have std available).

If you want to propose uplifting sparc64 to tier 2 with host tools, there's instructions at https://doc.rust-lang.org/nightly/rustc/target-tier-policy.html#tier-2-with-host-tools.

Note that you can already download std for that target today, it just won't have the compiler available: https://static.rust-lang.org/dist/rust-1.67.0-x86_64-unknown-linux-gnu.tar.gz. Maybe we should list tier 2 targets on the standalone installer page? I'm not sure if you're expecting to have just std or to have rustc as well.

I'm going to go ahead and close this. IMO we shouldn't track desire for uplifting targets; that should be initiated by people willing to be target maintainers (per the policy). The Project doesn't have bandwidth to take that work on ourselves.
