ABI checks: add support for tier2 arches See #131800 for the data collection behind this change. Also adds a test that exercise the "empty list of features" path. 2024-11-10 10:36:50 +00:00			warning: this function definition uses a SIMD vector type that (with the chosen ABI) requires the `sse` target feature, which is not enabled
Emit warning when calling/declaring functions with unavailable vectors. On some architectures, vector types may have a different ABI depending on whether the relevant target features are enabled. (The ABI when the feature is disabled is often not specified, but LLVM implements some de-facto ABI.) As discussed in rust-lang/lang-team#235, this turns out to very easily lead to unsound code. This commit makes it a post-monomorphization future-incompat warning to declare or call functions using those vector types in a context in which the corresponding target features are disabled, if using an ABI for which the difference is relevant. This ensures that these functions are always called with a consistent ABI. See the [nomination comment](https://github.com/rust-lang/rust/pull/127731#issuecomment-2288558187) for more discussion.
