De-duplicate consecutive libs when printing native-static-libs
This PR adds a de-duplicate step just before printing the `native-static-libs`.
This step de-duplicates all the consecutive libs based only on the relevant comparison elements (this exclude spans, ast elements, ...).
Fixes https://github.com/rust-lang/rust/issues/113209
Remove `LLVMRustCoverageHashCString`
Coverage has two FFI functions for computing the hash of a byte string. One takes a ptr/len pair (`LLVMRustCoverageHashByteArray`), and the other takes a NUL-terminated C string (`LLVMRustCoverageHashCString`).
But on closer inspection, the C string version is unnecessary. The calling-side code converts a Rust `&str` into a `CString`, and the C++ code then immediately turns it back into a ptr/len string before actually hashing it. So we can just call the ptr/len version directly instead.
---
This PR also fixes a bug in the C++ declaration of `LLVMRustCoverageHashByteArray`. It should be `size_t`, since that's what is declared and passed on the Rust side, and it's what `StrRef`'s constructor expects to receive on the callee side.
Don't require each rustc_interface tool to opt-in to parallel_compiler
Previously, forgetting to call `interface::set_thread_safe_mode` would cause the following ICE:
```
thread 'rustc' panicked at 'uninitialized dyn_thread_safe mode!', /rustc/dfe0683138de0959b6ab6a039b54d9347f6a6355/compiler/rustc_data_structures/src/sync.rs:74:18
```
This calls `set_thread_safe_mode` in `interface::run_compiler` to avoid requiring it in the caller.
Fixes `tests/run-make-fulldeps/issue-19371` when parallel-compiler is enabled.

rustdoc: use src consistently over source in CSS/JS
The two terms have been used, inconsistently, in closely related spots like the `src/` directory vs `source-files.js`, and with things like `src-sidebar-toggle` vs the `source-sidebar`. This PR changes most use of `source` to `src` instead (except the localStorage configuration variables, which would be very complicated to migrate).
It also renames `.srclink` to `.src`. This is mostly aiming to cut out one of those many little peanut-butter bits of bloat, and is consistent with how other link classes are done (like how you have `a.mod` stylesheet rules, but there's also a `mod` class put on the body tag).
Implement "items do not inherit unsafety" note for THIR unsafeck
Implements the "items do not inherit unsafety from separate enclosing items" note from the MIR unsafety checker in the THIR unsafety checker (`-Z thir-unsafeck`) to maintain parity between the two unsafety checkers. The logic to find the separate enclosing item is nearly the same as in the MIR unsafety checker.
misc bootstrap cleanups
- rename `detail_exit_macro` to `exit`
- remove unnecessary `Builder::new_standalone` function
- support `x suggest` with build-metrics
Structurally normalize in selection
We need to do this because of the fact that we're checking the `Ty::kind` on a type during selection, but goals passed into select are not necessarily normalized.
Right now, we're (kinda) unnecessarily normalizing the RHS of a trait upcasting goal, which is broken for different reasons (#113393). But I'm waiting for this PR to land before discussing that one.
r? `@lcnr`
This does three things:
1. Remove `forward!(Build, fn try_run())`. Having `try_run` behave differently as a free function than an associated function is confusing, and `Builder::try_run` is a very desirable name.
2. Move `test::try_run` and `run::try_run` to `Builder::try_run`. These functions are different than `Config::try_run` - they delay the failure and print it out at the end of the build.
3. Mark `Config::try_run` as deprecated to encourage people to use `Builder::try_run` instead.
Resurrect: rustc_target: Add alignment to indirectly-passed by-value types, correcting the alignment of byval on x86 in the process.
Same as #111551, which I [accidentally closed](https://github.com/rust-lang/rust/pull/111551#issuecomment-1571222612) :/

This resurrects PR #103830, which has sat idle for a while.
Beyond #103830, this also:
- fixes byval alignment for types containing vectors on Darwin (see `tests/codegen/align-byval-vector.rs`)
- fixes byval alignment for overaligned types on x86 Windows (see `tests/codegen/align-byval.rs`)
- fixes ABI for types with 128bit requested alignment on ARM64 Linux (see `tests/codegen/aarch64-struct-align-128.rs`)

`@pcwalton's` original PR description is reproduced below:
Commit 88e4d2c from five years ago removed
support for alignment on indirectly-passed arguments because of problems with
the `i686-pc-windows-msvc` target. Unfortunately, the `memcpy` optimizations I
recently added to LLVM 16 depend on this to forward `memcpy`s. This commit
attempts to fix the problems with `byval` parameters on that target and now
correctly adds the `align` attribute.
The problem is summarized in [this comment] by `@eddyb.` Briefly, 32-bit x86 has
special alignment rules for `byval` parameters: for the most part, their
alignment is forced to 4. This is not well-documented anywhere but in the Clang
source. I looked at the logic in Clang `TargetInfo.cpp` and tried to replicate
it here. The relevant methods in that file are
`X86_32ABIInfo::getIndirectResult()` and
`X86_32ABIInfo::getTypeStackAlignInBytes()`. The `align` parameter attribute
for `byval` parameters in LLVM must match the platform ABI, or miscompilations
will occur. Note that this doesn't use the approach suggested by eddyb, because
I felt it was overkill to store the alignment in `on_stack` when special
handling is really only needed for 32-bit x86.
As a side effect, this should fix#80127, because it will make the `align`
parameter attribute for `byval` parameters match the platform ABI on LLVM
x86-64.
[this comment]: #80822 (comment)
This caught several places which weren't waiting until the command finished to drop the Group.
I also took the liberty of calling `msg_sysroot_tool` from `run_cargo_test` to reduce code duplication and make errors like this less likely in the future.
This avoids the following broken logging in CI:
```
{"book":"test-pass","reference":"test-pass","rustbook":"test-fail","rust-by-example":"test-pass","nomicon":"test-pass","embedded-book":"test-pass","edition-guide":"test-pass"}::group::Building bootstrap
```
Allow escaping bound vars during `normalize_erasing_regions` in new solver
Add `AllowEscapingBoundVars` to `deeply_normalize`, and use it in the new solver in the `query_normalize` routine.
Ideally, we'd make all `query_normalize` calls handle pass in `AllowEscapingBoundVars` individually, because really the only `query_normalize` call that needs `AllowEscapingBoundVars::Yes` is the one in `try_normalize_generic_arg_after_erasing_regions`, but I think that's kind of overkill. I am happy to be convinced otherwise, though.
