It's passed to the underlying reader, so uninitialized memory == sad
times.
We might want to shrink the default buffer size as well. 64k is pretty
huge. Java uses 8k by default, and Go uses 4k for reference.

- Tables that are too wide for the screen scroll horizontally.
- Inline code that would force the page to become wider than the width
of the screen is broken in the middle of the word.
Fixes#20732, that all links in some modules point to the same code
examples was reported. The ID's generated for documents in
librustdoc are not all unique, which means the code rendered as
text is not being properly selected.
This change removes the unique id generation and instead changes the
frontend code to grab the correct code sample by it's relative
position in the dom.
For a call like `foo.bar()` where the method `bar` can't be resolved,
the compiler will search for traits that have methods with name `bar` to
give a more informative error, providing a list of possibilities.
Closes#7643.
There are two places left where we used to only know the byte
size of/offset into an array and had to cast to i8 and back to get the
right addresses. But by now, we always know the sizes in terms of the
number of elements in the array. In fact we have to add an extra Mul
instruction so we can use the weird cast-to-u8 code. So we should really
just embrace our new knowledge and use simple GEPs to do the address
calculations.
Additionally, the pointer calculations in bind_subslice_pat don't handle
zero-sized types correctly, producing slices that point outside the
array that is being matched against. Using GEP fixes that as well.
Fixes#3729
Also adjusted some of the FFI definitions because apparently they don't use the long pointer prefix.
Gives a free performance boost because `SRWLock` is several times faster than `CriticalRegion` on every Windows system tested.
Fixes#19962
This makes the tests much easier to maintain; the particular details
of the labels attached to exiting scopes is not worth the effort
required to keep it up to date as things change in the compiler
internals.
By returning the passed value black_box can be used on data being
passed to a function being benchmarked. This ensures the compiler
does not optimize the function for the input which could result in
the entire function being optimized away.

- Make punctuation/formatting consistent with the changes made to "The
Rust Programming Language" in #20782.
- Use title casing for "Safety and Speed" section.
- Reword some phrases to improve clarity.
