This will allow introducing a separate incr comp session dir for the post LTO artifacts in the future. In addition it statically encodes the lifetime of the incr comp session rather than requiring an enum behind a mutex stored in the Session.
The guard checked `data_len > u16::MAX`, allowing paths far larger than `PathBuffer` (a fixed 16384-element array), which the subsequent single `copy_from` then overflows. Bound against `MAXIMUM_REPARSE_DATA_BUFFER_SIZE` plus header instead, matching the kernel's limit.
Pure file moves; the module path repointing and platform gating follow in the next commit. Recorded in .git-blame-ignore-revs so blame skips the rename.
Select the platform implementation with a cfg_select! in sys::sync::futex, repoint each one at the pal primitives it uses (time, fuchsia, the windows api module, hermit_abi), and remove the now-unused futex declarations from the pal modules. The sync primitives import crate::sys::sync::futex rather than the crate::sys::futex glob re-export.
Use codegen tail discovery so wrappers such as OsStr keep slice element metadata without losing offsets for prefixed DSTs. Keep recursion tracking scoped to the current traversal path.
`rustc_privacy` pulls in all of `rustc_ty_utils`, but only wants `SpannedTypeVisitor` and `walk_types`. Move those to a small `rustc_ty_walk` crate. This allows `rustc_privacy` to start building much sooner.

…afe` Also renames it to `rustc_specialization_ignore_lifetime_constraints`
There is a `impl PpAnn for TyCtxt` that is unneeded. None of the big crates (middle, trait_selection) actually do any hir pretty printing so it can be removed and can either be implemented for local structs elsewhere or done by casting to `&dyn PpAnn` instead.
Clarify that slice-tail layout checks apply to the sized prefix rather than the slice element, and cover zero-sized slice elements in the type-tree run-make test.

Fixes a small typo in the documentation comment for AllowExprMetavar. Changes decrarative to `declarative`. Change in compiler/rustc_attr_parsing/src/parser.rs: Line 492
Reword the `.expect(...)` messages in the TcpStream/TcpListener doc examples in library/std/src/net/tcp.rs to follow the 'expect as precondition' style from the std library guidance (describe why the operation is expected to succeed, rather than restating the failure). Examples: "set_nodelay call failed" -> "set_nodelay should succeed" "could not set TTL" -> "set_ttl should succeed" "Cannot set non-blocking" -> "set_nonblocking should succeed" Doc-only change, no behavior change.

also refactor check-miri a bit to make it easier to read
Using a separate step lets us remove the `default_to_suites_only` hack.
