The official documentation sorely needs an explanation of the rust runtime and what it is exactly, and I want this guide to provide that information.
I'm unsure of whether I've been too light on some topics while too heavy on others. I also feel like a few things are still missing. As always, feedback is appreciated, especially about things you'd like to see written about!
This is a patch for #8005, thanks @lfairy for the hint.
It seems like `block.expr` is None, if the last line of a function has a semi colon (= it ends with a statement).
@kmcallister does this error message cover the intended use cases?
I'm not sure about the message, the wording and the span could probably be improved.
Unsuffixed literals like 1 and 1.1, and free type parameters sometimes
have to be printed in error messages, which ended up with \<V0>, \<VI0>
and \<VF0>. This change puts the words "generic" and "integer"/"float"
into the message so it's not a completely black box.

The gamma and bessel functions are of little utility outside a small specialized subset of use cases, and so they don't really make sense for inclusion in the standard library. The only reason they were included in the first place was to mirror libm, which is not a very good justification. If people need them for their own projects then they can make their own bindings to libm (which isn't too hard).

This is unnecessary and also leads to a bug: When the user specifies
```
#[crate_type = "rlib"];
```
rustpkg still creates a dylib.
Also it's good not to duplicate functionality. `build_session_options` handles this just fine.
Dead code pass now explicitly checks for `#[allow(dead_code)]` and
`#[lang=".."]` attributes on items and marks them as live if they have
those attributes. The former is done so that if we want to suppress
warnings for a group of dead functions, we only have to annotate the
"root" of the call chain.
Close#11380 and #11440.

a30d61b05a removed all of the trailing whitespace in doc/index.md.
Unfortunately, that trailing whitespace was actually markdown syntax for
line breaks.
This fixes the incorrect lexing of things like:
~~~rust
let b = 0o2f32;
let d = 0o4e6;
let f = 0o6e6f32;
~~~
and brings the float literal lexer in line with the description of the float literals in the manual.
Specifically, dissallow setting the number base for every type of float
literal, not only those that contain the decimal point. This is in line with
the description in the manual.
In general, you can run "rustpkg help <cmd>" to see some specific usage information for <cmd>. However, this was handled in a very ad-hoc and buggy manner. For example, running "rustpkg help prefer" would actually show you the usage information for the "uninstall" cmd. Or "rustpkg help test" would show you the usage information for the "build" command. Or "rustpkg help list" would just run the "list" command (and not show you anything usage information)
This commit attempts to fix this by making a new HelpCmd (and handling it explicitly)
