on s390x 128bit types have a smaller alignment then on x86[^1]. This leads to smaller structs and therefore the write_unaligned will write outside of the structs boundary. For now disable the tests on s390x. [^2] [^1]: s390x ELF ABI Table 1.1, Page 12 https://github.com/IBM/s390x-abi [^2]: rust-lang#149056 (comment) Co-authored-by: Ralf Jung <post@ralfj.de>
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 `ThreadLocalIndex` marker type, which ensures types arn't `Send`/`Sync`. This is a breaking change for users of the `rustc_public` crate. 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
Add doc for va_list APIs I observed that [PR146521](rust-lang#146521) submitted two weeks ago resolved some documentation issues related to `VaListImpl`, similar to the previous [PR136969](rust-lang#136969). This PR specifically adds requirements about argument availability for `VaListImpl::arg`, and also adds safety descriptions to the three associated intrinsic APIs.
alloc: fix `Debug` implementation of `ExtractIf` I noticed this while reviewing rust-lang#141032. Calling `get` on the inner `Vec` never returns `Some` as the `Vec`'s length is temporarily set to zero while the `ExtractIf` exists.

…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`````

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
```
