make unsupported_calling_conventions a hard error #129935

RalfJung · 2024-09-03T16:52:10Z

This has been a future-compat lint (not shown in dependencies) since Rust 1.55, released 3 years ago. Hopefully that was enough time so this can be made a hard error now. Given that long timeframe, I think it's justified to skip the "show in dependencies" stage. There were not many crates hitting this even when the lint was originally added.

This should get cratered, and I assume then it needs a t-compiler FCP. (t-compiler because this looks entirely like an implementation oversight -- for the vast majority of ABIs, we already have a hard error, but some were initially missed, and we are finally fixing that.)

Fixes #87678

@craterbot check
The fact that crater is Linux-only is actually good here; on Windows the ABI keeps being accepted on all targets, only on other OSes does it get rejected.

6 crates on crates.io are affected, those all look like genuine regressions. They are all rarely used (the one with most downloads has 12k total downloads, that one also has not seen any updates in 8 years).

I have filed issues for the 4 crates that saw updates in the last 5 years, see the backlinks above.

RalfJung · 2024-09-09T06:21:32Z

@fee1-dead I think this is then ready for review.

Does it need a t-compiler FCP because it is a breaking change?

[Stabilize MSRV-aware resolver config] (rust-lang/cargo#14639) - [Stabilize resolver v3] (rust-lang/cargo#14754) Rustdoc ------- - [rustdoc-search: improve type-driven search] (rust-lang/rust#127589) Compatibility Notes ------------------- - [Enable by default the `LSX` target feature for LoongArch Linux targets] (rust-lang/rust#132140) - [The unstable `-Zprofile` flag ("gcov-style" coverage instrumentation) has been removed.](rust-lang/rust#131829) This does not affect the stable flags for coverage instrumentation (`-Cinstrument-coverage`) and profile-guided optimization (`-Cprofile-generate`, `-Cprofile-use`), which are unrelated and remain available. - Support for the target named `wasm32-wasi` has been removed as the target is now named `wasm32-wasip1`. This completes the [transition] (rust-lang/compiler-team#607) [plan](rust-lang/compiler-team#695) for this target following [the introduction of `wasm32-wasip1`] (rust-lang/rust#120468) in Rust 1.78. Compiler warnings on [use of `wasm32-wasi`] (rust-lang/rust#126662) introduced in Rust 1.81 are now gone as well as the target is removed. - [The syntax `&pin (mut|const) T` is now parsed as a type which in theory could affect macro expansion results in some edge cases] (rust-lang/rust#130635 (comment)) - [Legacy syntax for calling `std::arch` functions is no longer permitted to declare items or bodies (such as closures, inline consts, or async blocks).] (rust-lang/rust#130443 (comment)) - The `wasm32-unknown-emscripten` target's binary release of the standard library is now [built with the latest emsdk 3.1.68] (rust-lang/rust#131533), which fixes an ABI-incompatibility with Emscripten >= 3.1.42. If you are locally using a version of emsdk with an incompatible ABI (e.g. before 3.1.42 or a future one), you should build your code with `-Zbuild-std` to ensure that `std` uses the correct ABI. - [Declaring functions with a calling convention not supported on the current target now triggers a hard error] (rust-lang/rust#129935) - [The next-generation trait solver is now enabled for coherence, fixing multiple soundness issues] (rust-lang/rust#130654)
