Note that the output of `unpretty-debug.stdout` has changed. In that
test the hash values are normalized from a symbol numbers to small
numbers like "0#0" and "0#1". The increase in the number of static
symbols must have caused the original numbers to contain more digits,
resulting in different pretty-printing prior to normalization.
lint: use `transparent_newtype_field` to avoid ICE
Fixes#73747.
This PR re-uses the `transparent_newtype_field` function instead of manually calling `is_zst` on normalized fields to determine which field in a transparent type is the non-zero-sized field, thus avoiding an ICE.
typeck: use `item_name` in cross-crate packed diag
Fixes#73112.
This PR replaces the use of `expect_local` and `hir().get` to fetch the identifier for a ADT with `item_name` - which works across crates.
pprust: support multiline comments within lines
Fixes#73626.
This PR adds support to `rustc_ast_pretty` for multiline comments that start and end within a line of source code.
Fun fact: [the commit which added this assert](d12ea39896) was from 2011!

When encountering a unit or tuple pattern for a struct-like item, suggest
using the correct pattern.
Use `insert_field_names_local` when evaluating variants and store field
names even when the list is empty in order to produce accurate
structured suggestions.

typeck: report placeholder type error w/out span
Fixes#74086.
This PR fixes a regression introduced in rust-lang/rust#70369 which meant that an error was not being emitted for invalid placeholder types when there wasn't a span available.

typeck: check for infer before type impls trait
Fixes#73886.
This PR checks that the target type of the cast (an error related to which is being reported) does not have types to be inferred before checking if it implements the `From` trait.

Added detailed error code explanation for issue E0688 in Rust compiler.

rustdoc: Allow linking from private items to private types
Fixes#74134
After PR #72771 this would trigger an intra_doc_link_resolution_failure warning
when rustdoc is invoked without --document-private-items. Links from private
items to private types are however never actually generated in that case and
thus shouldn't produce a warning. These links are in fact a very useful tool to
document crate internals.
Tests are added for all 4 combinations of public/private items and link
targets. Test 1 is the case mentioned above and fails without this commit. Tests
2 - 4 passed before already but are added nonetheless to prevent regressions.
This commit adds support to rustc_ast_pretty for multiline comments that
start and end within a line of source code.

debuginfo: Mangle tuples to be natvis friendly, typedef basic types
These changes are meant to unblock rust-lang/rust#70052 "Update hashbrown to 0.8.0" by allowing the use of `tuple<u64, u64>` as a .natvis expression in MSVC style debuggers (MSVC, WinDbg, CDB, etc.)
* f8eb81b does the actual mangling of `(u64, u64)` -> `tuple<u64, 64>`
* 24a728a allows `u64` to resolve (fixing `$T1` / `$T2` when used to visualize `HashMap<u64, u64, ...>`)
Stabilize `transmute` in constants and statics but not const fn
cc #53605 (leaving issue open so we can add `transmute` to `const fn` later)
Previous attempt: #64011
r? @RalfJung
cc @rust-lang/wg-const-eval
As per the discussion in PR #74147, the 4 individual tests are replaced by a
single one.
The test is expanded to cover all 4 public/private cases, each with and without
--document-private-items.
Only add CFGuard on `windows-msvc` targets
As @ollie27 pointed out in #73893, the `cfguard` module flag causes incorrect behavior on `windows-gnu` targets. This patch restricts rustc to only add this flag for `windows-msvc` targets (this may need to be changed if other linkers gain support for CFGuard).
adjust ub-enum test to be endianess-independent
@cuviper noted that our test fails on "other" endianess systems (I never know which is which^^), so let's fix that.
