Description
Proposal
Promote the following Tier 2 without Host Tools targets to Tier 2 with Host Tools:
aarch64-unknown-linux-ohos
armv7-unknown-linux-ohos
x86_64-unknown-linux-ohos
Requirements for Tier 2 with Host Tools
Depending on the target, its capabilities, its performance, and the likelihood of use for any given tool, the host tools provided for a tier 2 target may include only
rustc
andcargo
, or may include additional tools such asclippy
andrustfmt
.
rustc
, cargo
, clippy
and rustfmt
are required.
Approval of host tools will take into account the additional time required to build the host tools, and the substantial additional storage required for the host tools.
Maybe the infrastructure team will have to comment on this.
The host tools must have direct value to people other than the target's maintainers. (It may still be a niche target, but the host tools must not be exclusively useful for an inherently closed group.) This requirement will be evaluated independently from the corresponding tier 2 requirement.
There must be a reasonable expectation that the host tools will be used, for purposes other than to prove that they can be used.
These targets and host tools are intended for use by application developers on the OpenHarmony platform.
The host tools must build and run reliably in CI (for all components that Rust's CI considers mandatory), though they may or may not pass tests.
OK.
Building host tools for the target must not take substantially longer than building host tools for other targets, and should not substantially raise the maintenance burden of the CI infrastructure.
Yes.
The host tools must provide a substantively similar experience as on other targets, subject to reasonable target limitations.
Yes.
If the host tools for the platform would normally be expected to be signed or equivalent (e.g. if running unsigned binaries or similar involves a "developer mode" or an additional prompt), it must be possible for the Rust project's automated builds to apply the appropriate signature process, without any manual intervention by either Rust developers, target maintainers, or a third party. This process must meet the approval of the infrastructure team.
Currently works without a signature.
Providing host tools does not exempt a target from requirements to support cross-compilation if at all possible.
There targets are already well-supported by cross compilation.
All requirements for tier 2 apply.
These targets are already supported in Tier 2.

Process
The main points of the Major Change Process are as follows:
- File an issue describing the proposal.
- A compiler team member or contributor who is knowledgeable in the area can second by writing
@rustbot second
.- Finding a "second" suffices for internal changes. If however, you are proposing a new public-facing feature, such as a
-C flag
, then full team check-off is required. - Compiler team members can initiate a check-off via
@rfcbot fcp merge
on either the MCP or the PR.
- Finding a "second" suffices for internal changes. If however, you are proposing a new public-facing feature, such as a
- Once an MCP is seconded, the Final Comment Period begins. If no objections are raised after 10 days, the MCP is considered approved.

Comments
This issue is not meant to be used for technical discussion. There is a Zulip stream for that. Use this issue to leave procedural comments, such as volunteering to review, indicating that you second the proposal (or third, etc), or raising a concern that you would like to be addressed.
