This is now printed on the same line. Use NEXT/SAME depending on the LLVM version.

The two xors get folded into the select.

On LLVM 21 additional %esp adjustments are generated. Don't use NEXT to allow these.

This updates the wasi-sdk used in CI to build release binaries and run CI with. No major motivation beyond keeping things up-to-date and following the development of wasi-sdk.

…buginfo, r=wesleywiser tests: Test line number in debuginfo for diverging function calls Closes rust-lang#59558 which just [E-needs-test](rust-lang#59558 (comment)). The bug seems to have been fixed in **nightly-2021-05-10**: ```sh for toolchain in nightly-2021-05-09 \ nightly-2021-05-10 \ 1.88; do echo -e "\nWith $toolchain:" rustc +$toolchain tests/codegen/diverging-function-call-debuginfo.rs --emit llvm-ir -o /tmp/out.ll -g -Clto -Copt-level=0 build/x86_64-unknown-linux-gnu/ci-llvm/bin/FileCheck --input-file /tmp/out.ll tests/codegen/diverging-function-call-debuginfo.rs --check-prefix=CHECK --dump-input-context 10 2>/dev/null && echo OK || echo FAIL done ``` ``` With nightly-2021-05-09: FAIL With nightly-2021-05-10: OK With 1.88: OK ``` which gives the following list of candidate commits. Not clear which one it is exactly but it doesn't matter much since we can confirm that the test works.

Fix Ord, Eq and Hash implementation of panic::Location Fixes rust-lang#144486. Now properly compares/hashes the filename rather than the pointer to the string.

…t-nomination, r=jieyouxu,Urgau Enable T-compiler backport nomination This patches the triagebot.toml so that it will trigger a backport label on pull requests fixing regressions. Applying a backport label will trigger creating a Zulip thread. For now the configuration only for `T-compiler` labeled regressions. Comments in the code explain how it works. Documentation [on the forge](https://forge.rust-lang.org/triagebot/backport.html). ``` [backport.foo] # The pull request MUST have one of these labels required_pr_labels = ["T-compiler"] # The regression MUST have this label required_issue_label = "regression-from-stable-to-beta" # if the above conditions matches, the PR will receive these labels add_labels = ["beta-nominated"] ``` Anything to think about before merging this? thanks for a review

…ark-Simulacrum Update wasi-sdk to 27.0 in CI This updates the wasi-sdk used in CI to build release binaries and run CI with. No major motivation beyond keeping things up-to-date and following the development of wasi-sdk.

…ude, r=petrochenkov Resolve: cachify `ExternPreludeEntry.binding` through a `Cell` Provides interior mutability to the `binding` field of `ExternPreludeEntry` as this field behaves like a cache. Per [zulip thread](https://rust-lang.zulipchat.com/#narrow/channel/421156-gsoc/topic/Project.3A.20Parallel.20Macro.20Expansion/near/531390914). A little preparatory work for batched import resolution, which is part of [#gsoc > Project: Parallel Macro Expansion](https://rust-lang.zulipchat.com/#narrow/channel/421156-gsoc/topic/Project.3A.20Parallel.20Macro.20Expansion). r? `@petrochenkov`

Update some tests for LLVM 21 Fixes rust-lang#144604. Fixes rust-lang#144606. r? `@durin42`

Update rustc-perf submodule Mostly to include rust-lang/rustc-perf#2204.

Add support for the m68k architecture in 'object_architecture' This is a tiny PR that adds the m68k architecture to `object_architecture`. This allows us to build rmeta files for that ISA(we use the object crate to pack metadata into object files).

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
