This is a tracking issue for `rtm_target_feature`, the `rtm` target feature on x86. See https://github.com/rust-lang/rust/issues/44839 for discussion from before this feature got its own tracking issue. ### About tracking issues Tracking issues are used to record the overall progress of implementation. They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions. A tracking issue is however *not* meant for large scale discussion, questions, or bug reports about a feature. Instead, open a dedicated issue for the specific matter and add the relevant feature gate label. Discussion comments will get marked as off-topic or deleted. Repeated discussions on the tracking issue may lead to the tracking issue getting locked. ### Steps <!-- Include each step required to complete the feature. Typically this is a PR implementing a feature, followed by a PR that stabilises the feature. However for larger features an implementation could be broken up into multiple PRs. --> - [ ] Figure out ABI interactions and other possible blockers/concerns - [ ] Final Comment Period (FCP) - [ ] Stabilization PR ([see instructions on rustc-dev-guide][stabilization-guide]) [stabilization-guide]: https://rustc-dev-guide.rust-lang.org/stabilization_guide.html#stabilization-pr [doc-guide]: https://rustc-dev-guide.rust-lang.org/stabilization_guide.html#documentation-prs [nightly-style-procedure]: https://github.com/rust-lang/style-team/blob/main/nightly-style-procedure.md [Style Guide]: https://github.com/rust-lang/rust/tree/HEAD/src/doc/style-guide ### Unresolved Questions <!-- Include any open questions that need to be answered before the feature can be stabilised. --> none at the moment ### Implementation history <!-- Include a list of all the PRs that were involved in implementing the feature. -->
