followed by a semicolon.
This allows code like `vec![1i, 2, 3].len();` to work.
This breaks code that uses macros as statements without putting
semicolons after them, such as:
fn main() {
...
assert!(a == b)
assert!(c == d)
println(...);
}
It also breaks code that uses macros as items without semicolons:
local_data_key!(foo)
fn main() {
println("hello world")
}
Add semicolons to fix this code. Those two examples can be fixed as
follows:
fn main() {
...
assert!(a == b);
assert!(c == d);
println(...);
}
local_data_key!(foo);
fn main() {
println("hello world")
}

Closes#18635.

Windows dbghelp strips leading underscores from symbols, and I could not find a way to turn this off. So let's accept "ZN...E" form too.
Also, print PC displacement from symbols. This is helpful in gauging whether the PC was indeed within the function displayed in the backtrace, or whether it just happened to be the closest public symbol in the module.

We discussed coercions for `if` and `match` expressions. `if` seems to work already, was there some specific behaviour which wasn't working?
There is currently no way to specify the stability level for a trait
impl produced by `deriving`. This patch is a stopgap solution that:
* Turns of stability inheritance for trait impls, and
* Uses the stability level of the *trait* if no level is directly
specified.
That is, manual trait impls may still provide a directly stability
level, but `deriving` will use the level of the trait. While not a
perfect solution, it should be good enough for 1.0 API stabilization, as
we will like *remove* any unwanted impls outright.
This narrows the definition of nested returns such that only when the
outer return has a chance of being executed (due to the inner return
being conditional) do we mark the function as having nested returns.
Fixes#19684
If you configure with `--disable-docs`, the `doc` directory does not get generated, so
`cp -r doc dist/` fails when you `make dist{,-tar-bins,-doc}` or `make install`
Fix `make TAGS.emacs`.
@nikomatsakis has been complaining to me about this. (I had not noticed since I drive `ctags` with a separate script.)
(Suitable for a rollup build.)
This is to encourage the use of the sugary syntax instead of the `<>` syntax, which will not be usable post-1.0. Rustdoc [still uses the `<>` syntax](https://github.com/rust-lang/rust/issues/19909), so if a rustdoc wizard is looking for something to do, it would be nice to use the parenthetical syntax there as well. (I tried to patch rustdoc as well, but failed…)
Fixes some tuple indexing deprecation warnings. Didn't test. Don't see how it could fail unless I need to modify a makefile somewhere...

Was testing rustup on a very minimal Debian installation and got errors during the install process (error occurred in `install.sh` of the Rust nightly.)
Noticed that Rustup was downloading the i686 nightly instead of x86-64. Installing `file` fixed the problem, and this patch adds the probe to ensure file is installed before attempting to use it.
There may still be an issue with the i686 installation, I did not investigate further.
Added -Z print-region-graph debugging option; produces graphviz visualization of region inference constraint graph.
Optionally uses environment variables `RUST_REGION_GRAPH=<path_template>` and `RUST_REGION_GRAPH_NODE=<node-id>` to select which file to output to and which AST node to print.
Relax some of the bounds on the decoder methods back to FnMut to help accomodate
some more flavorful variants of decoders which may need to run the closure more
than once when it, for example, attempts to find the first successful enum to
decode.
