notes This commit extends the `#[diagnostic::on_unimplemented]` (and `#[rustc_on_unimplemented]`) attributes to allow multiple `note` options. This enables emitting multiple notes for custom error messages. For now I've opted to not change any of the existing usages of `#[rustc_on_unimplemented]` and just updated the relevant compile tests.

…t-codegen This ensures that cg_clif can be built for targets that aren't natively supported by Cranelift. It will not be possible to compile for the host in this case, but cross-compilation will still be possible. We won't distribute cg_clif as rustup component for any targets that aren't natively supported by Cranelift, but will still build it if codegen-backends lists "cranelift".

This adds support for loongarch and a bunch of other targets

…ilee Bump stdarch submodule and remove special handling for LLVM intrinsics that are no longer needed Bumps stdarch to pull rust-lang/stdarch#1477, which reimplemented some functions with portable SIMD intrinsics instead of arch specific LLVM intrinsics. Handling of those LLVM intrinsics is removed from cranelift codegen and miri. cc `@RalfJung` `@bjorn3`

…rk-Simulacrum Distribute cg_clif as rustup component on the nightly channel This makes it possible to use cg_clif using: ```bash $ rustup component add rustc-codegen-cranelift-preview --toolchain nightly $ RUSTFLAGS="-Zcodegen-backend=cranelift" cargo +nightly build ``` cc rust-lang/compiler-team#405. r? `@Mark-Simulacrum`

The LLVM backend is generally available, while the gnu assembler is not on Windows and many other platforms by default.

But exclude sym operands for now as they are somewhat broken.

Now that we don't manually pass around indent levels, there's no need for these worker methods to exist separately from their main callers.

This is fixes the issue wherein typeck was succeeding for break-with-value at illegal locations such as inside `while`, `while let` and `for` loops which eventually caused an ICE during MIR interpetation for const eval. Now we fail typeck for such code which prevents faulty MIR from being generated and interpreted, thus fixing the ICE.

…piler-errors Print variadic argument pattern in HIR pretty printer Variadic argument name/pattern was ignored during HIR pretty printing. Could not figure out why it only works on normal functions (`va2`) and not in foreign ones (`va1`).

…ngjubilee Use ImageDataType for allocation type Suggested at rust-lang#100499 cc `@dvdhrm` cc `@nicholasbishop`

…mplemented, r=compiler-errors Allows `#[diagnostic::on_unimplemented]` attributes to have multiple notes This commit extends the `#[diagnostic::on_unimplemented]` (and `#[rustc_on_unimplemented]`) attributes to allow multiple `note` options. This enables emitting multiple notes for custom error messages. For now I've opted to not change any of the existing usages of `#[rustc_on_unimplemented]` and just updated the relevant compile tests. r? `@compiler-errors` I'm happy to adjust any of the existing changed location to emit the old error message if that's desired.

coverage: Replace manual debug indents with nested tracing spans in `counters` Instead of indenting these debug messages manually, we can get `#[instrument]` to do a better job of it for us, giving us some nice little simplifications.

…oli-obk Stabilize inline asm usage with rustc_codegen_cranelift Previously using inline asm with the cg_clif version built as part of rustc would return an error that inline asm support is unstable. Recently I implemented everything that remained for full support of inline asm with the exception of sym operands (which remain marked as unstable for cg_clif). As such I think it is time to declare the inline asm support of cg_clif stable. `@rustbot` label +A-codegen +A-cranelift +T-compiler

…li-obk Ignore RPIT duplicated lifetimes in `opaque_types_defined_by` An RPIT's or TAIT's own generics are kinda useless -- so just ignore them. For TAITs, they will always be empty, and for RPITs, they're always duplicated lifetimes. Fixes rust-lang#115013.

…-obk Fail typeck for illegal break-with-value This is fixes the issue wherein typeck was succeeding for break-with-value exprs at illegal locations such as inside `while`, `while let` and `for` loops which eventually caused an ICE during MIR interpretation for const eval. Now we fail typeck for such code which prevents faulty MIR from being generated and interpreted, thus fixing the ICE. Fixes rust-lang#114529

…-obk deduce_param_attrs: explain a read-only case This takes the discussion [here](https://github.com/rust-lang/rust/pull/111517/files#r1243443625) and adds it as comment in the code. Cc `@lukas-code`
