This adds some extra docs for the `no-prefer-dynamic` header. And also a `s/must_compile_successfully/compile_pass`. `must_compile_successfully` has been renamed to `compile_pass` at some point in the past and this comment was still referring to the old name.

It's a primitive slice method, not a standalone function.
…mertj Document the -Z flag to the rustc book # Description Changes: - Added new documentation on the `-Z` flag of rustc in the command-line arguments section of the rustc book. If I need to rephrase anything or if you have any improvements, please let me know! I deliberately did not create an exhaustive list of all options since they are likely to change over time and per toolchain version. closes rust-lang#41142

Kill dead code dominator code.
Hi,
Whilst fiddling around in the dominator code, I found some (I think) unused code. This code *was* used at the time it was imported, but over time it seems to have become redundant.
I've tested a build up to stage 1 with no problems. Maybe the tests will turn up something though.
P.S.
There is a FIXME comment in `dominators/mod.rs`:
```
pub fn is_dominated_by(&self, node: Node, dom: Node) -> bool {
// FIXME -- could be optimized by using post-order-rank
self.dominators(node).any(|n| n == dom)
}
```
I'm not sure of the intention of this comment. The `Dominators` struct already operates over post-order rank nodes. Any ideas?

…idtwco improve unknown enum variant errors Fixes rust-lang#56517.
Remove strange formatting in `Ordering` docs. I can't really fathom what the intent of the brackets is. The [original PR](rust-lang#12956) doesn't give any hints. I think it seems fine without them.

…0.2, r=steveklabnik Update TRPL to use mdbook 0.2 I ran linkchecker locally and it passed. Let's see if I did it correctly...
Remove note about transmute for float bitpatterns. This particular usecase has been safely abstracted in these `std` functions: [f32::to_bits](https://doc.rust-lang.org/std/primitive.f32.html#method.to_bits), [f32::from_bits](https://doc.rust-lang.org/std/primitive.f32.html#method.from_bits), [f64::to_bits](https://doc.rust-lang.org/std/primitive.f64.html#method.to_bits), [f64::from_bits](https://doc.rust-lang.org/std/primitive.f64.html#method.from_bits). So, I think we shouldn't recommend an unnecessary use of `unsafe` here anymore.

save-analysis: Pull associated type definition using `qpath_def` Closes rust-lang/rls#1390 This (probably?) fixes the case where we run the save-analysis code on the following snippet: ```rust trait Test<'a> { type Thing: Test2; } trait Test2 { fn print(); } #[allow(unused)] fn example<T>(t: T) where T: for<'a> Test<'a> { T::Thing::print(); //~ ERROR cannot extract an associated type from a higher-ranked trait bound in this context // ^ only errors in save-analysis mode } ``` The chain is as follows: - culprit is `hir_ty_to_ty` - which calls `ast_ty_to_ty` in the `ItemCtxt` - which calls `associated_path_to_ty` - which finally fails on `projected_ty_from_poly_trait_ref` https://github.com/rust-lang/rust/blob/3de0106789468b211bcc3a25c09c0cf07119186d/src/librustc_typeck/collect.rs#L212-L224 I'm not exactly sure why `hir_ty_to_ty` fails - is it because it needs more setup from typeck to work correctly? I'm guessing the fix is okay since we just pull the already typeck'd data (we run save-analysis after all the analysis passes are complete) from the tables. With this change we can 'go to def' on all segments in the `T::Thing::print()` path.
