…aces, r=jyn514 Only deduplicate stack traces for good path bugs Fixes rust-lang#106267 Restores backtraces for `bug!` and `delay_span_bug` after rust-lang#106056. Only `delay_good_path_bug` needed its backtraces to be deduplicated, since it spits out the backtrace where it was created when it's being emitted. Before: ``` error: internal compiler error: /home/ubuntu/rust2/compiler/rustc_middle/src/ty/relate.rs:638:13: var types encountered in super_relate_consts: Const { ty: usize, kind: Infer(Var(_#0c)) } Const { ty: usize, kind: Param(N/#1) } note: the compiler unexpectedly panicked. this is a bug. note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md note: rustc 1.68.0-dev running on x86_64-unknown-linux-gnu query stack during panic: #0 [typeck] type-checking `<impl at /home/ubuntu/test.rs:7:1: 7:34>::trigger` #1 [typeck_item_bodies] type-checking all item bodies #2 [analysis] running analysis passes on this crate end of query stack error: aborting due to 2 previous errors ``` Hmm... that's a little bare.

There were a series of unfortunate interactions here. Here's an MCVE of the test this fixes (committed as `tests/ui/meta/no_std-extern-libc.rs`): ```rust #![crate_type = "lib"] #![no_std] #![feature(rustc_private)] extern crate libc; ``` Before, this would give an error about duplicate versions of libc: ``` error[E0464]: multiple candidates for `rlib` dependency `libc` found --> fake-test-src-base/allocator/no_std-alloc-error-handler-default.rs:15:1 | LL | extern crate libc; | ^^^^^^^^^^^^^^^^^^ | = note: candidate #1: /home/gh-jyn514/rust/build/aarch64-unknown-linux-gnu/stage2/lib/rustlib/aarch64-unknown-linux-gnu/lib/liblibc-358db1024b7d9957.rlib = note: candidate #2: /home/gh-jyn514/rust/build/aarch64-unknown-linux-gnu/stage2/lib/rustlib/aarch64-unknown-linux-gnu/lib/liblibc-ebc478710122a279.rmeta ``` Both these versions were downloaded from CI, but one came from the `rust-std` component and one came from `rustc-dev`: ``` ; tar -tf build/cache/f2d9a3d0771504f1ae776226a5799dcb4408a91a/rust-std-nightly-x86_64-unknown-linux-gnu.tar.xz | grep liblibc rust-std-nightly-x86_64-unknown-linux-gnu/rust-std-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-unknown-linux-gnu/lib/liblibc-68a2d9e195dd6ed2.rlib ; tar -tf build/cache/f2d9a3d0771504f1ae776226a5799dcb4408a91a/rustc-dev-nightly-x86_64-unknown-linux-gnu.tar.xz | grep liblibc rustc-dev-nightly-x86_64-unknown-linux-gnu/rustc-dev/lib/rustlib/x86_64-unknown-linux-gnu/lib/liblibc-f226c9fbdd92a0fd.rmeta ``` The fix was to only copy files from `rust-std` unless a Step explicitly requests for the `rustc-dev` components to be available by calling `builder.ensure(compile::Rustc)`. To avoid having to re-parse the `rustc-dev.tar.xz` tarball every time, which is quite slow, this adds a new `build/host/ci-rustc/.rustc-dev-contents` cache file which stores only the names of files we need to copy into the sysroot. This also allows reverting the hack in rust-lang#110121; now that we only copy rustc-dev on-demand, we can correctly add the `Rustc` check artifacts into the sysroot, so that this works correctly even when `download-rustc` is forced to `true`. --- See rust-lang#108767 (comment) for why `no_std` is required for the MCVE test to fail; it's complicated and not particularly important. Fixes rust-lang#108767.

…t, r=tmiasko Encode def span for foreign return-position `impl Trait` in trait Fixes rust-lang#111031, yet another def-span encoding issue :/ Includes a smaller repro than the issue, but I can confirm it ICEs: ``` query stack during panic: #0 [def_span] looking up span for `rpitit::Foo::bar::{opaque#0}` #1 [object_safety_violations] determining object safety of trait `rpitit::Foo` #2 [check_is_object_safe] checking if trait `rpitit::Foo` is object safe #3 [typeck] type-checking `main` #4 [used_trait_imports] finding used_trait_imports `main` #5 [analysis] running analysis passes on this crate ``` Luckily since this only affects nightly, this desn't need to be backported.

Change prefetch to avoid deadlock Was abled to reproduce the deadlock in rust-lang#118205 and created a coredump when it happen. When looking at the backtraces I noticed that the prefetch of exported_symbols (Thread 17 frame 4) started after the "actual" exported_symbols (Thread 2 frame 18) but it also is working on some of the collect_crate_mono_items (Thread 17 frame12 ) that Thread 2 is blocked on resulting in a deadlock. This PR results in less parallell work that can be done at the same time but from what I can find we do not call the query exported_symbols from multiple places in the same join call any more. ```
