…celinval rustc_public: Make Id types !Send / !Sync These types are Id's to a table stored in TLS, so using them from another tread will either panic, or give wrong results. Therefor, I've added a ~~`ReferencesTls`~~`ThreadLocalIndex` marker type, which ensures types arn't `Send`/`Sync`. This is a breaking change for users of the `rustc_public` crate. ~~It also changes how `DefId` and similar are `Serialize`d. It would be possible to preserve the old behavior if that's needed, but I couldn't see any tests for these.~~ EDIT: Not anymore: rust-lang#148261 (comment) Zulip Discussion: https://rust-lang.zulipchat.com/#narrow/channel/320896-project-stable-mir/topic/WDYM.20.22should.20not.20.20be.20shared.20across.20threads.22/with/547374171
…nsized, r=bjorn3 ignore unsized types in mips64 and sparc64 callconvs Non-rustic calling conventions should not make up an ABI for unsized types (cc rust-lang#148302). The vast majority of our callconv implementations already ignore unsized types, `sparc64` and `mips64` I guess were missed. r? ```@bjorn3```
…-out-of-spite-does-it-matter, r=GuillaumeGomez rustdoc-json: add rlib path to ExternalCrate to enable robust crate resolution Historically, it's not been possible to robustly resolve a cross-crate item in rustdoc-json. If you had a `Id` that wasn't in `Crate::index` (because it was defined in a different crate), you could only look it up it `Crate::paths`. But there, you don't get the full information, only an `ItemSummary`. This tells you the `path` and the `crate_id`. But knowing the `crate_id` isn't enough to be able to build/find the rustdoc-json output with this item. It's only use is to get a `ExternalCrate` (via `Crate::external_crates`). But that only tells you the `name` (as a string). This isn't enough to uniquely identify a crate, as there could be multiple versions/features [^1] [^2]. This was originally proposed to be solved via `@LukeMathWalker's` `--orchestrator-id` proposal (rust-lang/compiler-team#635). But that requires invasive changes to cargo/rustc. This PR instead implements `@Urgau's` proposal to re-use the path to a crate's rmeta/rlib as a unique identifer. Callers can use that to determine which package it corresponds to in the language of the build-system above rustc. E.g. for cargo, `cargo rustdoc --message-format=json --output-format=json -Zunstable-options`). (Once you've found the right external crate's rustdoc-json output, you still need to resolve the path->id in that crate. But that's """just""" a matter of walking the module tree. We should probably still make that nicer (by, for example, allowing sharing `Id`s between rustdoc-json document), but that's a future concern) For some notes from RustWeek 2025, where this was designed, see https://hackmd.io/0jkdguobTnW7nXoGKAxfEQ CC `@obi1kenobi` (who wants this for cargo-semver-checks [^3]), `@epage` (who's conversations on what and wasn't possible with cargo informed taking this approach to solve this problem) r? `@GuillaumeGomez` ## TODO: - [x] Docs: [Done](https://github.com/rust-lang/rust/compare/e4cdd0c24a994fed354081b5f907680a11f2ddc5..457ed4edb184997d5d6f879c6a220bc4d69ff6fd) - [x] Tests: [Done](https://github.com/rust-lang/rust/compare/2e1b954dc52bf7e5a6e9311394df760db37d383f..4d00c1a7ee5e03d1e78801cc01a85dac08ab603b) [^1]: rust-lang/compiler-team#635 (comment) § Problem [^2]: https://rust-lang.zulipchat.com/#narrow/channel/266220-t-rustdoc/topic/Identifying.20external.20crates.20in.20Rustdoc.20JSON/with/352701211 [^3]: obi1kenobi/cargo-semver-checks#638
…rite, r=RalfJung
fix the fragment_in_dst_padding_gets_overwritten test on s390x
on s390x 128bit types have a smaller alignment then on x86[^1]. This leads to smaller structs (24 instead of 32 bytes) and therefore the write_unaligned will write outside of the structs boundary.
To fix the test, change the trailing u32 into a u8. This will generate 7 trailing padding bytes on s390x and 15 on x86_64. Also change the start of the garbage data so it will span over x,y and padding:
```
s390x: XXXXXXXXXXXXXXXXY-------
x86_64: XXXXXXXXXXXXXXXXY---------------
GGGGGGGG
```
