Use a valid name for graphviz graphs
Hiridification has broken graphviz output because `HirId` has a more complex display implemetation than `NodeId`. Since the id was just used to generate a distinct identifier, we just pull out the various constituent indexed.
This commit makes two changes - separating the `NodeId` that identifies
an enum variant from the `NodeId` that identifies the variant's
constructor; and no longer creating a `NodeId` for `Struct`-style enum
variants and structs.
Separation of the variant id and variant constructor id will allow the
rest of RFC 2008 to be implemented by lowering the visibility of the
variant's constructor without lowering the visbility of the variant
itself.
No longer creating a `NodeId` for `Struct`-style enum variants and
structs mostly simplifies logic as previously this `NodeId` wasn't used.
There were various cases where the `NodeId` wouldn't be used unless
there was an unit or tuple struct or enum variant but not all uses of
this `NodeId` had that condition, by removing this `NodeId`, this must
be explicitly dealt with. This change mostly applied cleanly, but there
were one or two cases in name resolution and one case in type check
where the existing logic required a id for `Struct`-style enum variants
and structs.
Remove inline assembly from hint::spin_loop
This PR removes the inline assembly which was not required since these
instructions are available in core::arch, and extends support of
the spin_loop hint to arm targets with the v6 feature which also
support the yield instruction.
Track changes to robots.txt
Currently `robots.txt` of doc.rust-lang.org is not part of any repo, so there's [no way to contribute any changes to it](https://internals.rust-lang.org/t/deadlock-about-fixing-outdated-documentation-links-in-search-engines/9374), such as needed for #44894 and countless dupes of this issue.
I propose adding it to this repo. I'm not in control of the infrastructure, so I can't help to automate deployment of it, but even just having the file under source control is IMHO a step forward.
Remove `track_errors` from `check_match`, `typeck_item_bodies` and `register_plugins`
In the spirit of continuing through errors in type checking (#39275), remove `track_errors` from a couple of locations in the codebase.
HirIdification: kill off NodeId stragglers
The final stages of HirIdification (#57578).
This PR, along with https://github.com/rust-lang/rust/pull/59042, should finalize the HirIdification process (at least the more straightforward bits).
- replace `NodeId` with `HirId` in `trait_impls`
- remove all `NodeId`s from `borrowck`
- remove all `NodeId`s from `typeck`
- remove all `NodeId`s from `mir`
- remove `trait_auto_impl` (unused)
I would be cool to also remove `NodeId` from `hir::def::Def`, `middle::privacy::AccessLevel` and `hir::ItemId`, but I don't know if this is feasible.
I'll be happy to do more if I've missed anything.
middle: replace NodeId with HirId in AccessLevels
Pushing the limits of HirIdification (#57578).
Replaces `NodeId` with `HirId` in `middle::privacy::AccessLevels`. Actually this time I was more successful and cracked it; I probably tried to HirIdify too much at once when I attempted it last time ^^.

A convenience method like fs::copy() should try to prevent pitfalls a
normal user doesn't think about.
In case of an empty umask, setting the file mode early prevents
temporarily world readable or even writeable files,
because the default mode is 0o666.
In case the target is a named pipe or special device node, setting the
file mode can lead to unwanted side effects, like setting permissons on
`/dev/stdout` or for root setting permissions on `/dev/null`.
copy_file_range() returns EINVAL, if the destination is a FIFO/pipe or
a device like "/dev/null", so fallback to io::copy, too.
Use `fcopyfile` on MacOS instead of `copyfile`.

In order to minimize the verbosity of common syntax errors that are parsed
as type ascription, hide the feature gate error unless there are no other
errors being emitted by the parser.
Since commit 9452a8dfa3ba, the new debug info format is only generated
for LLVM 8 and newer versions. However, the tests still assume that LLVM
7 will use the new debug info format. Fix the tests (and a comment in
the code) to match the actual version check.
