2e2924f263 Split and rename the annotation structs.
`NoAnn` and `IdentifiedAnnotation` impl both `pprust_ast::PpAnn` and
`pprust_hir::PpAnn`, which is a bit confusing, because the optional
`tcx` is only needed for the HIR cases. (Currently the `tcx` is
unnecessarily provided in the `expanded` AST cases.)

This commit splits each one into `Ast` and `Hir` versions, which makes
things clear about where the `tcx` is needed. The commit also renames
all the traits so they consistently end with `Ann`.

060851b764 Remove pretty-printing traits.
`call_with_pp_support_ast` and `call_with_pp_support_hir` how each have
a single call site. This commit inlines and removes them, which also
removes the need for all the supporting traits: `Sess`,
`AstPrinterSupport`, and `HirPrinterSupport`. The `sess` member is also
removed from several structs.

7d145a0fde Merge print_* functions.
The handling of the `PpMode` variants is currently spread across three
functions: `print_after_parsing`, `print_after_hir_lowering`, and
`print_with_analysis`. Each one handles some of the variants. This split
is primarily because `print_after_parsing` has slightly different
arguments to the other two.

This commit changes the structure. It merges the three functions into a
single `print` function, and encapsulates the different arguments in a
new enum `PrintExtra`.

Benefits:
- The code is a little shorter.
- All the `PpMode` variants are handled in a single `match`, with no
  need for `unreachable!` arms.
- It enables the trait removal in the subsequent commit by reducing
  the number of `call_with_pp_support_ast` call sites from two to one.

e3d8bbbfe2 Simplify support traits.
First, both `AstPrinterSupport` and `HirPrinterSupport` have a `sess`
method. This commit introduces a `Sess` trait and makes the support
traits be subtraits of `Sess`, to avoid some duplication.

Second, both support traits have a `pp_ann` method that isn't needed if
we enable `trait_upcasting`. This commit removes those methods.

(Both of these traits will be removed in a subsequent commit, as will
the `trait_upcasting` use.)

Rollup merge of #113565 - workingjubilee:better-signal-handler-message, r=pnkfelix
Make SIGSEGV handler emit nicer backtraces

This annotates the code heavily with comments to explain what is going on, for the benefit of other compiler contributors. The backtrace also emits appropriate comments to clarify, to a programmer who may not know why a bunch of file paths and hexadecimal blather was just dumped into stderr, what is going on. Finally, it detects cycles and uses their regularity to avoid repeating a bunch of text. The previous backtraces we were emitting was extremely unfriendly, potentially confusing, and often alarming, and this makes things almost "nice".

We can't necessarily make them much nicer than this, because a signal handler must use "signal-safe" functions. This precludes conveniences like dynamic allocations. Fortunately, Rust's stdlib has allocation-free formatting, but it may hinder integrating this error with our localization middleware, as I wasn't able to clearly ascertain, at a glance, whether there was a zero-alloc path through it.

Rollup merge of #113780 - dtolnay:printkindpath, r=b-naber
Support `--print KIND=PATH` command line syntax

As is already done for `--emit KIND=PATH` and `-L KIND=PATH`.

In the discussion of #110785, it was pointed out that `--print KIND=PATH` is nicer than trying to apply the single global `-o` path to `--print`'s output, because in general there can be multiple print requests within a single rustc invocation, and anyway `-o` would already be used for a different meaning in the case of `link-args` and `native-static-libs`.

I am interested in using `--print cfg=PATH` in Buck2. Currently Buck2 works around the lack of support for `--print KIND=PATH` by [indirecting through a Python wrapper script](d43cf3a51a/prelude/rust/tools/get_rustc_cfg.py) to redirect rustc's stdout into the location dictated by the build system.

From skimming Cargo's usages of `--print`, it definitely seems like it would benefit from `--print KIND=PATH` too. Currently it is working around the lack of this by inserting `--crate-name=___ --print=crate-name` so that it can look for a line containing `___` as a delimiter between the 2 other `--print` informations it actually cares about. This is commented as a "HACK" and "abuse". 31eda6f7c3/src/cargo/core/compiler/build_context/target_info.rs (L242) (FYI `@weihanglo` as you dealt with this recently in https://github.com/rust-lang/cargo/pull/11633.)

1e65b5b741 Add recursion detection to signal-safe backtrace
This cleans up the formatting of the backtrace considerably,
dodging the fact that a backtrace with recursion normally
emits hundreds of lines. Instead, simply write repeated symbols,
and add how many times the recursion occurred.
Also, it makes it look more like the "normal" backtrace.

Some fine details in the code are important for reducing
the amount of possible panic branches.

4fa00c2507 Explain SIGSEGV backtrace handler
...to both compiler contributors and other rustc invokers.
The previous error messaging was extremely unfriendly,
and potentially both confusing and alarming.

The entire modules is extracted into a new file to help
ease of reading, and plenty of comments get layered in.
The design of the messaging is focused on preventing
the overall purpose of the output from being too opaque
in common cases, so users understand why it is there.
There's not an immediate need for it being actionable,
but some suggestions are offered anyways.

d52eb4f99a Don't require each rustc_interface tool to opt-in to parallel_rustc support
Previously, forgetting to call `interface::set_thread_safe_mode` would cause the following ICE:
```

```

This calls `set_thread_safe_mode` in `interface::run_compiler` to avoid requiring it in the caller.

6a1c10bd85 Add a simple markdown parser for formatting rustc --explain
Currently, the output of `rustc --explain foo` displays the raw markdown in a
pager. This is acceptable, but using actual formatting makes it easier to
understand.

This patch consists of three major components:

1.  A markdown parser. This is an extremely simple non-backtracking recursive
    implementation that requires normalization of the final token stream
2.  A utility to write the token stream to an output buffer
3.  Configuration within rustc_driver_impl to invoke this combination for
    `--explain`. Like the current implementation, it first attempts to print to
    a pager with a fallback colorized terminal, and standard print as a last
    resort.

    If color is disabled, or if the output does not support it, or if printing
    with color fails, it will write the raw markdown (which matches current
    behavior).

    Pagers known to support color are: `less` (with `-r`), `bat` (aka `catbat`),
    and `delta`.

The markdown parser does not support the entire markdown specification, but
should support the following with reasonable accuracy:

-   Headings, including formatting
-   Comments
-   Code, inline and fenced block (no indented block)
-   Strong, emphasis, and strikethrough formatted text
-   Links, anchor, inline, and reference-style
-   Horizontal rules
-   Unordered and ordered list items, including formatting

This parser and writer should be reusable by other systems if ever needed.

1da1348924 Remove Queries::ongoing_codegen.
There's no need to store it in `Queries`. We can just use a local
variable, because it's always used shortly after it's produced.

The commit also removes the `tcx.analysis()` call in `ongoing_codegen`,
because it's easy to ensure that's done beforehand.

All this makes the dataflow within `run_compiler` easier to follow, at
the cost of making one test slightly more verbose, which I think is a
good tradeoff.

Write to stdout if `-` is given as output file

With this PR, if `-o -` or `--emit KIND=-` is provided, output will be written to stdout instead. Binary output (those of type `obj`, `llvm-bc`, `link` and `metadata`) being written this way will result in an error unless stdout is not a tty. Multiple output types going to stdout will trigger an error too, as they will all be mixded together.

This implements https://github.com/rust-lang/compiler-team/issues/431

The idea behind the changes is to introduce an `OutFileName` enum that represents the output - be it a real path or stdout - and to use this enum along the code paths that handle different output types.

781111ef35 Use Cow in {D,Subd}iagnosticMessage.
Each of `{D,Subd}iagnosticMessage::{Str,Eager}` has a comment:
```
// FIXME(davidtwco): can a `Cow<'static, str>` be used here?
```
This commit answers that question in the affirmative. It's not the most
compelling change ever, but it might be worth merging.

This requires changing the `impl<'a> From<&'a str>` impls to `impl
From<&'static str>`, which involves a bunch of knock-on changes that
require/result in call sites being a little more precise about exactly
what kind of string they use to create errors, and not just `&str`. This
will result in fewer unnecessary allocations, though this will not have
any notable perf effects given that these are error paths.

Note that I was lazy within Clippy, using `to_string` in a few places to
preserve the existing string imprecision. I could have used `impl
Into<{D,Subd}iagnosticMessage>` in various places as is done in the
compiler, but that would have required changes to *many* call sites
(mostly changing `&format("...")` to `format!("...")`) which didn't seem
worthwhile.

rustc driver: Remove argument 0 before at-expansion to prevent ICE

Under Unix-based operating systems, when I execute rustc by setting argv0 to ``@/dev/null`,` it will expand command-line arguments from this file, leading to an empty arglist, which then triggers an ICE by trying to remove first argument.

The panic message is this:
```

```

My fix is to remove the first argument before expanding arguments.

I also checked if I can trigger a similar problem by passing empty argument list to `execve`, but at least under Linux, it seems to always insert an empty first argument if there are none.

01e33a3600 Avoid &format("...") calls in error message code.
Error message all end up passing into a function as an `impl
Into<{D,Subd}iagnosticMessage>`. If an error message is creatd as
`&format("...")` that means we allocate a string (in the `format!`
call), then take a reference, and then clone (allocating again) the
reference to produce the `{D,Subd}iagnosticMessage`, which is silly.

This commit removes the leading `&` from a lot of these cases. This
means the original `String` is moved into the
`{D,Subd}iagnosticMessage`, avoiding the double allocations. This
requires changing some function argument types from `&str` to `String`
(when all arguments are `String`) or `impl
Into<{D,Subd}iagnosticMessage>` (when some arguments are `String` and
some are `&str`).

Introduce `DynSend` and `DynSync` auto trait for parallel compiler

part of parallel-rustc #101566

This PR introduces `DynSend / DynSync` trait and `FromDyn / IntoDyn` structure in rustc_data_structure::marker. `FromDyn` can dynamically check data structures for thread safety when switching to parallel environments (such as calling `par_for_each_in`). This happens only when `-Z threads > 1` so it doesn't affect single-threaded mode's compile efficiency.

Rollup merge of #105354 - BlackHoleFox:apple-deployment-printer, r=oli-obk
Add deployment-target --print flag for Apple targets

This is very useful for crates that need to know what the Apple OS deployment target is for their build scripts or inside of a build environment. Right now, the defaults just get copy/pasted around the ecosystem since they've been stable for so long. But with #104385 in progress, that won't be true anymore and everything will need to move. Ideally whenever it happens again, this could be less painful as everything can ask the compiler what its default is instead.

To show examples of the copy/paste proliferation, here's some crates and/or apps that do:
- [cc](https://github.com/rust-lang/cc-rs/pull/708/files), Soon
-  [mac-notification-sys](https://github.com/h4llow3En/mac-notification-sys/pull/46/files#diff-d0d98998092552a1d3259338c2c71e118a5b8343dd4703c0c7f552ada7f9cb42R10-R12)

b5d3d970fa Add rustc_fluent_macro to decouple fluent from rustc_macros
Fluent, with all the icu4x it brings in, takes quite some time to
compile. `fluent_messages!` is only needed in further downstream rustc
crates, but is blocking more upstream crates like `rustc_index`. By
splitting it out, we allow `rustc_macros` to be compiled earlier, which
speeds up `x check compiler` by about 5 seconds (and even more after the
needless dependency on `serde_json` is removed from
`rustc_data_structures`).

d1fcf61117 errors: generate typed identifiers in each crate
Instead of loading the Fluent resources for every crate in
`rustc_error_messages`, each crate generates typed identifiers for its
own diagnostics and creates a static which are pulled together in the
`rustc_driver` crate and provided to the diagnostic emitter.

22a5125a36 Remove save-analysis.
Most tests involving save-analysis were removed, but I kept a few where
the `-Zsave-analysis` was an add-on to the main thing being tested,
rather than the main thing being tested.

For `x.py install`, the `rust-analysis` target has been removed.

For `x.py dist`, the `rust-analysis` target has been kept in a
degenerate form: it just produces a single file `reduced.json`
indicating that save-analysis has been removed. This is necessary for
rustup to keep working.

Closes #43606.

Rollup merge of #107838 - estebank:terminal_hyperlinks, r=nagisa
Introduce `-Zterminal-urls` to use OSC8 for error codes

Terminals supporting the OSC8 Hyperlink Extension can support inline anchors where the text is user defineable but clicking on it opens a browser to a specified URLs, just like `<a href="URL">` does in HTML.

Rollup merge of #107761 - oli-obk:miri_🪵, r=TaKO8Ki
Replace a command line flag with an env var to allow tools to initialize the tracing loggers at their own discretion

fixes https://github.com/rust-lang/miri/issues/2778

this was introduced in https://github.com/rust-lang/rust/pull/104645, so this PR reverts the flag-part and uses an env var instead.
