Disabling loading of pretty printers in the debugger itself is more reliable. Before this commit the .gdb_debug_scripts section couldn't be included in dylibs or rlibs as otherwise there is no way to disable the section anymore without recompiling the entire standard library.

Conceptually `EarlyBinder` does not contain an `Interner` so it shouldn't tell Rust it does via `PhantomData`. This is necessary for rust-analyzer as it stores `EarlyBinder`s in query results which require `Sync`, placing restrictions on our interner setup.

This method now returns a string instead of printing directly to (possibly-captured) stdout.

This reduces the amount of "hidden" printing in error-reporting code, which will be helpful when overhauling compiletest's error handling and output capture.

…Noratrieb Implement `hash_map` macro Implementation of rust-lang#144032 Implements the `hash_map` macro under `std/src/macros.rs`.

…ter_section, r=jieyouxu Remove the omit_gdb_pretty_printer_section attribute Disabling loading of pretty printers in the debugger itself is more reliable. Before this commit the .gdb_debug_scripts section couldn't be included in dylibs or rlibs as otherwise there is no way to disable the section anymore without recompiling the entire standard library.

…iler-errors Multiple bounds checking elision failures regression test for rust-lang#120433

compiletest: Preliminary cleanup of `ProcRes` printing/unwinding While experimenting with changes to how compiletest handles output capture, error reporting, and unwinding, I repeatedly ran in to difficulties with this core code for reporting test failures caused by a subprocess. There should be no change in compiletest output. r? jieyouxu

…ler-errors `Interner` arg to `EarlyBinder` does not affect auto traits Conceptually `EarlyBinder` does not contain an `Interner` so it shouldn't tell Rust it does via `PhantomData`. This is necessary for rust-analyzer as it stores `EarlyBinder`s in query results which require `Sync`, placing restrictions on our interner setup. r? compiler-errors

…leLapkin Update E0562 to account for the new impl trait positions fixes rust-lang#142683

…ler-errors Return a struct with named fields from `hash_owner_nodes` While looking through this code for other reasons, I noticed a nice opportunity to return a struct with named fields instead of a tuple. The first patch also introduces an early-return to flatten the rest of `hash_owner_nodes`. There are further changes that could potentially be made here (renaming things, `Option<Hashes>` instead of optional fields), but I'm not deeply familiar with this code so I didn't want to disturb the calling code too much.

Updated test links in compiler Updated test links since a bunch of tests got moved around from the top level recently r? compiler

Use full flag name in strip command for Darwin Darwin always uses `rust-objcopy` which supports long-form flags Solaris unchanged due to not having support for `--discard-all` and only `-x` fixes rust-lang#135038 r? ````@WaffleLapkin```` (since bot will ping you anyway, feel free to reroll)

…mpiler-errors,scottmcm Forbid tail calling intrinsics There is only one intrinsic that can be called on stable, as far as I can find, (`transmute`).

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.

If the regression was expected or you think it can be justified,
please write a comment with sufficient written justification, and add
@rustbot label: +perf-regression-triaged to it, to mark the regression as triaged.
If you think that you know of a way to resolve the regression, try to create
a new PR with a fix for the regression.
If you do not understand the regression or you think that it is just noise,
you can ask the @rust-lang/wg-compiler-performance working group for help (members of this group
were already notified of this PR).
