89e437354a rustc_trans: remove primitive_align optimization. 2017-11-19 20:33:46 +02:00

1a9dc2e902 dead code lint to say "never constructed" for variants 
As reported in #19140, #44083, and #44565, some users were confused when
the dead-code lint reported an enum variant to be "unused" when it was
matched on (but not constructed). This wording change makes it clearer
that the lint is in fact checking for construction.

We continue to say "used" for all other items (it's tempting to say
"called" for functions and methods, but this turns out not to be
correct: functions can be passed as arguments and the dead-code lint
isn't special-casing that or anything).

Resolves #19140.

d8d5b6180f Auto merge of #46074 - scottmcm:unspecialize-nth, r=bluss 
Undo the Sized specialization from Iterator::nth

I just added this as part of https://github.com/rust-lang/rust/pull/45595, but I'm now afraid there's a specialization issue with it, since I tried to add [another similar specialization](https://github.com/rust-lang/rust/compare/master...scottmcm:faster-iter-by-ref?expand=1#diff-1398f322bc563592215b583e9b0ba936R2390), and ended up getting really disturbing test failures like
```
thread 'iter::test_by_ref_folds' panicked at 'assertion failed: `(left == right)`
  left: `15`,
 right: `15`', src\libcore\../libcore/tests\iter.rs:1720:4
```

So since this wasn't the most critical part of the change and a new beta is branching within a week, I think putting this part back to what it was before is the best option.
