HashMap and HashSet require keys to implement TotalEq. This makes it possible to use TypeId as a HashMap key again.
Question for reviewers: assuming we want to support `HashMap<TypeId, whatever>`, would it make sense to add a relevant test? If so, should it go to libcollections or libstd?
Summary:
So far, we've used the term POD "Plain Old Data" to refer to types that
can be safely copied. However, this term is not consistent with the
other built-in bounds that use verbs instead. This patch renames the Pod
kind into Copy.

This reverts commit 7180b5de44.
We don't particularly need this, I've never seen it clutter up the docs, it just seemed nice at the time. Sadly it caused a regression for reexported methods.
Closes#13091
The previous dependency calculation was based on an arbitrary set of asterisks
at an arbitrary depth, but using the recursive version should be much more
robust in figuring out what's dependent.
A variety of stuff here, mostly aimed at making `make install` work correctly with `--libdir` and `--mandir`. `make install` again goes through `install.sh`.
This commit removes implicitly adding the Send bound to ~Trait objects and
procedure types. It will now be manually required to specify that a procedure
or trait must be send-able.
Closes#10296
This bench is meant to exercise libgreen, not libnative. It recently caused the
auto-linux-32-nopt-t bot to fail as no output was produced for an hour.
We really do *not* want TCO to kick in. If it does, we'll never blow the
stack, and never trigger the condition the test is checking for. To that end,
do a meaningless alloc that serves only to get a destructor to run. The
addition of nocapture/noalias seems to have let LLVM do more TCO, which
hurt this testcase.
When calling
make verify-grammar
a lot of errors are reported by llnextgen.
Only simple errors like:
missing semicolons,
missing single quotes,
usage of parentheses instead of squared brackets or
usage of single quote instead of double quote
are fixed by this patch.
This can only be tested, when llnextgen is installed.

When calling
make verify-grammar
or when llnextgen is not installed:
python2.7 src/etc/extract_grammar.py <src/doc/rust.md
an error is reported by extract_grammar.py that the
keyword "crate" is not defined.
This patch adds the keyword "crate" to the grammar in rust.md.

The `_match.rs` takes advantage of passes prior to `trans` and
aggressively prunes the sub-match tree based on exact equality. When it
comes to literal or range, the strategy may lead to wrong result if
there's guard function or multiple patterns inside tuple.

The previous syntax was `Foo:Bound<trait-parameters>`, but this is a little
ambiguous because it was being parsed as `Foo: (Bound<trait-parameters)` rather
than `Foo: (Bound) <trait-parameters>`
This commit changes the syntax to `Foo<trait-parameters>: Bound` in order to be
clear where the trait parameters are going.
Closes#9265
This change prepares `rustc` to accept private fields by default. These changes will have to go through a snapshot before the rest of the changes can happen.

Add some docs to ExpnInfo. Add a single overlooked `new_span` call to the folder (I'm pretty sure nothing reads this span, though, so it's probably pointless).
This change is in preparation for #8122. Nothing is currently done with these
visibility qualifiers, they are just parsed and accepted by the compiler.

The problem was that we need to apply the substitution, so that the
formal lifetime parameters get replaced with (unifiable)
free-lifetimes that can actually be fed into the constraint solver.
Also, refactor code os that substitution for `check_item` and
`check_method`, moving both down the control flow into `check_bare_fn`.
----
Finally, there was another (similar) spot where we needed to
substitute early-bound lifetimes when invoking an object method of a
trait.

This was leaving Decls without the new spans; this is a minor change,
since literally nothing reads in the code base reads the span of a Decl
itself, always just its contents.
Apparently we had forgotten to do this for freebsd, causing possible problems
on FreeBSD 10. The discussion in #12324 has some more details about how it's
missing.
