Generics are tightened by making order significant. This means `Vec` now matches only with a true vector of allocators, instead of matching the second type param. It also makes unboxing within generics stricter, so `Result` only matches if `B` is in the error type and `A` is in the success type. The top level of the function search is unaffected.

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.

This has since been fixed. The GCC backend should always produce object files that work with lld unless lld for whatever reason drops GCC support. Most of the other more niche backends don't use cg_ssa's linker code at all. If they do and don't work with lld, they can always disable lld usage using a cli argument. Without this commit using cg_clif is by default in a non-trivial amount of cases a perf regression on Linux due to ld.bfd being a fair bit slower than lld. It is possible to explicitly enable it without this commit, but most users are unlikely to do this. --- compiler/rustc_codegen_ssa/src/back/link.rs | 17 ----------------- 1 file changed, 17 deletions(-) diff --git a/compiler/rustc_codegen_ssa/src/back/link.rs b/compiler/rustc_codegen_ssa/src/back/link.rs index 8f754debaf0d2..3120b5bf0af67 100644 --- a/compiler/rustc_codegen_ssa/src/back/link.rs +++ b/compiler/rustc_codegen_ssa/src/back/link.rs @@ -3305,23 +3305,6 @@ fn add_lld_args( let self_contained_cli = sess.opts.cg.link_self_contained.is_linker_enabled(); let self_contained_target = self_contained_components.is_linker_enabled(); - // FIXME: in the future, codegen backends may need to have more control over this process: they - // don't always support all the features the linker expects here, and vice versa.

LLVM does not expect to ever see multiple dbg_declares for the same variable at the same location with different values. proc-macros make it possible for arbitrary code, including multiple calls that get inlined, to happen at any given location in the source code. Add discriminators when that happens so these locations are different to LLVM. This may interfere with the AddDiscriminators pass in LLVM, which is added by the unstable flag -Zdebug-info-for-profiling.

The previous PR left out these two features because they weren't expected to change much about compiled code so it was unclear what the rationale was. It has [since been discovered][blog] that `reference-types` can be useful as it changes the binary format of the `call_indirect` instruction. Additionally [on Zulip][zulip] there's a use case of detecting these features at compile time and generating a compile error to better warn users about features not supported on engines. This PR then additionally adds the `tail-call` feature which corresponds to the [tail-call] proposal to WebAssembly. This feature advanced to "phase 4" in the WebAssembly CG awhile back and has been supported in LLVM for quite some time now. Engines are finishing up implementations or have already shipped implementations, so while this is a bit of a late addition to Rust itself it reflects the current status of WebAssembly's state of the feature. A test has been added here not only for these features but other WebAssembly features as well to showcase that they're usable without feature gates in stable Rust.
