book: match enum warning
Matching enums with named fields in the previous way yielded the "non_shorthand_field_patterns" warning.
The new code shows the shorthand syntax as well as field renaming, so it should be exhaustive ;-)
Remove proc_macro from the tidy whitelist again
PR #38842 has exposed that we were missing the src/test/compile-fail-fulldeps
directory in the search for feature gate tests. Because the detection didn't
work despite the effort to name the test appropriately and add a correct
"// gate-test-proc_macro" comment, proc_macro was added to the whitelist.
We fix this little weakness in the feature gate tidy check and add
the src/test/compile-fail-fulldeps directory to the checked directories.
Part of issue #39059 .

libstd: replace all `try!` with `?` in documentation examples
See #38644.
For the record, I used the following Perl one-liner and then manually fixed a couple of things it got wrong:
$ perl -p -i -e 's#(///.*)try!\((.*)\)#$1$2?#' src/libstd/**/*.rs
Add error explanation for E0328.
This PR adds an explanation for an error in the list in #32777.
I haven't used this feature myself, so I was piecing it together from the docs. Please let me know if any changes in wording should be made.
One problem: When I followed the instructions in CONTRIBUTING.md, it said to run `make check-stage1` before posting the PR. This reported failures, but they seemed to be intermittent. I got different numbers of failures on each run. Here's the output for the last run

Use fs::symlink_metadata in doc for is_symlink
fs::metadata() follows symlinks so is_symlink() will always return
false. Use symlink_metadata instead in the example in the
documentation.
See issue #39088.
syntax: remove abi::Os and abi::Architecture
They're long dead since the switch to flexible targets, but was not removed like their consumers were. Interesting they even got maintained by various porters out there!
Technically [syntax-breaking] as they're public API, but since they're unused in the compiler, the potential breakage IMO should be minimal.
Document that `Metadata` can be obtained from `symlink_metadata`
When retrieving the information about a syslink (specifically, when invoking `Metadata::is_symlink`) you generally want the `syslink_metadata`. It would be natural to point at both options to retrieve a `Metadata` value, as they are both appropriate (for different use cases).
* Command::envs() now takes anything that is IntoIterator<Item=(K, V)>
where both K and V are AsRef<OsStr>.
* Since we're not 100% sure that's the right signature, envs() is
now marked unstable. (You can use envs() with HashMap<str, str> but
not Vec<(str, str)>, for instance.)
* Update the test to match.
* By analogy, args() now takes any IntoIterator<Item=S>, S: AsRef<OsStr>.
This should be uncontroversial.
linkchecker: Fix checking links which are just fragments
Also fix a typo which linkchecker should have caught.
It was broken by 31a8638e5e716bec90f4398a57c58fb34e492667.

Fix rustbuild to work with --libdir.
Similar to the makefiles, pass CFG_LIBDIR_RELATIVE to cargo when building
rustc in stages > 0. This tells rustc to check the different directory.
I'm not sure how you want this handled in the toml system (my distribution, Gentoo, uses configure still). I have a feeling the system needs a rework anyways for rustbuild. If there is some discussion that needs to happen, could you merge this in the mean time? I'd be happy to help transition this to a better method.
