…notriddle Add jump to doc I'm using the source code pages of the compiler quite a lot, but one thing missing is the possibility to jump back from the source code to the item documentation. Since I also got a few others complaining about it, I think it's fine to add it since this option is nightly only. This PR adds a link to jump back to item's documentation on the item definition (so on `Bar` in `struct Bar {... }`, as described in the unofficial [RFC](https://github.com/GuillaumeGomez/rfcs/blob/rustdoc-jump-to-definition/text/000-rustdoc-jump-to-definition.md)). r? ````@notriddle````

Add Adt to SMIR r? ````@oli-obk````

make MCP510 behavior opt-in to avoid conflicts between the CLI and target flavors Fixes rust-lang#113597, which contains more details on how this happens through the code, and showcases an unexpected `Gnu(Cc::Yes, Lld::Yes)` flavor. rust-lang#112910 added support to use `lld` when the flavor requests it, but didn't explicitly do so only when using `-Clink-self-contained=+linker` or one of the unstable `-Clinker-flavor`s. The problem: some targets have a `lld` linker and flavor, e.g. `thumbv6m-none-eabi` from that issue. Users can override the linker but there are no linker flavors precise enough to describe the linker opting out of lld: when using `-Clinker=arm-none-eabi-gcc`, we infer this is a `Cc::Yes` linker flavor, but the `lld` component is unknown and therefore defaulted to the target's linker flavor, `Lld::Yes`. <details> <summary>Walkthrough of how this happens</summary> The linker flavor used is a mix between what can be inferred from the CLI (`-C linker`) and the target's default linker flavor: - there is no linker flavor on the CLI (and that also offers another workaround on nightly: `-C linker-flavor=gnu-cc -Zunstable-options`), so it will have to be inferred [from here](https://github.com/lqd/rust/blob/5dac6b320be868f898a3c753934eabc79ff2e406/compiler/rustc_codegen_ssa/src/back/link.rs#L1334-L1336) to [here](https://github.com/lqd/rust/blob/5dac6b320be868f898a3c753934eabc79ff2e406/compiler/rustc_codegen_ssa/src/back/link.rs#L1321-L1327). - in [`infer_linker_hints`](https://github.com/lqd/rust/blob/5dac6b320be868f898a3c753934eabc79ff2e406/compiler/rustc_target/src/spec/mod.rs#L320-L352) `-C linker=arm-none-eabi-gcc` infers a `Some(Cc::Yes)` cc hint, and no hint about lld. - the target's `linker_flavor` is combined in `with_cli_hints` with these hints. We have our `Cc::Yes`, but there is no hint about lld, [so the target's flavor `lld` component is used](https://github.com/lqd/rust/blob/5dac6b320be868f898a3c753934eabc79ff2e406/compiler/rustc_target/src/spec/mod.rs#L356-L358). It's [`Gnu(Cc::No, Lld::Yes)`](https://github.com/rust-lang/rust/blob/993deaa0bf8bab9dd3eadfd1fbeb093328e95afe/compiler/rustc_target/src/spec/thumb_base.rs#L35). - so we now have our `Gnu(Cc::Yes, Lld::Yes)` flavor </details> This results in a `Gnu(Cc::Yes, Lld::Yes)` flavor on a non-lld linker, causing an additional unexpected `-fuse-ld=lld` argument to be passed. I don't know if this target defaulting to `rust-lld` is expected, but until MCP510's new linker flavor are stable, when people will be able to describe their linker/flavor accurately, this PR keeps the stable behavior of not doing anything when the linker/flavor on the CLI unexpectedly conflict with the target's. I've tested this on a `no_std` `-C linker=arm-none-eabi-gcc -C link-arg=-nostartfiles --target thumbv6m-none-eabi` example, trying to simulate one of `cortex-m`'s test mentioned in issue rust-lang#113597 (I don't know how to build a local complete `thumbv6m-none-eabi` toolchain to run the exact test), and checked that `-fuse-lld` was indeed gone and the error disappeared. r? `````@petrochenkov`````

This is a doc regression on html5ever, so possibly #113623. That benchmark looks usually stable and noise is less likely.

However, benchmarks weren't supposed to be affected by that PR if I understand correctly; maybe some of the additional work happens on regular codepaths, and not only when source links are on.

This is probably fine but let's cc PR author @GuillaumeGomez and reviewer @notriddle just in case.

GuillaumeGomez · 2023-07-14T12:49:44Z

The change in #113623 is behind a disabled-by-default option, so it seems very unlikely to come from this one.

lqd · 2023-07-14T14:14:24Z

It's the only PR that looks like it could impact a doc benchmark in this rollup.

GuillaumeGomez · 2023-07-14T14:19:41Z

Then no clue.

lqd · 2023-07-14T14:29:09Z

Let's launch a perf run for the PR just in case it's noise.

@rust-timer build ef7ad853d355f408a8b1ee8a007bd8c4be4f9838

Is the perf hit acceptable to T-rustdoc ? Or would the team like to investigate whether some codepaths were changed that were not protected by some verification that the option in question is enabled ? If the regression is acceptable/expected/not worth investigating, simply mark this PR as perf-regression-triaged.

GuillaumeGomez · 2023-07-14T14:48:29Z

We have a suspicion about an unnecessary string allocation. Sending a fix.
