2019-10-17Inline and remove `iterate_until_fixed_point()`.Nicholas Nethercote-39/+28
The commit also removes the debug statement, because they annoyed me. This change wins another 1% on `unicode_normalization`, at least partly because it no longer needs to increment `iteration`.
2019-10-16Auto merge of #63756 - Zoxc:sharded-dep-graph-1, r=nikomatsakisbors-60/+72
Use more fine grained locks for the dep graph Split out from https://github.com/rust-lang/rust/pull/61845. r? @michaelwoerister cc @aturon
2019-10-17Use a `BitSet` in `LexicalResolver::iterate_until_fixed_point()`.Nicholas Nethercote-5/+18
This wins 3% on `unicode_normalization`.

2019-10-15Rollup merge of #65389 - ecstatic-morse:zero-sized-array-no-drop, r=eddybTyler Mandry-0/+3
Return `false` from `needs_drop` for all zero-sized arrays. Resolves #65348. This changes the result of the `needs_drop` query from `true` to `false` for types such as `[Box<i32>; 0]`. I believe this change to be sound because a zero-sized array can never actually hold a value. This is an elegant way of resolving #65348 and #64945, but obviously it has much broader implications.

2019-10-15Rollup merge of #65293 - tmandry:turbo-expander, r=matthewjasperTyler Mandry-4/+17
Optimize `try_expand_impl_trait_type` A lot of time was being spent expanding some large `impl Future` types in fuchsia. This PR takes the number of types being visited in one expansion from >3 billion to about a thousand, and eliminates the compile time regression in https://github.com/rust-lang/rust/issues/65147 (in fact, compile times are better than they were before). Thanks to @Mark-Simulacrum for helping identify the issue and to @matthewjasper for suggesting this change. Fixes #65147. r? @matthewjasper,@nikomatsakis
2019-10-15Rollup merge of #64623 - matthewjasper:underscore-imports, r=petrochenkovTyler Mandry-1/+1
Remove last uses of gensyms Underscore bindings now use unique `SyntaxContext`s to avoid collisions. This was the last use of gensyms in the compiler, so this PR also removes them. closes #49300 cc #60869 r? @petrochenkov
2019-10-15Rollup merge of #64603 - gilescope:unused-lifetime-warning, r=matthewjasperTyler Mandry-1/+7
Reducing spurious unused lifetime warnings. Fixes #61115, fixes #64493.

2019-10-15Use structured suggestion for restricting boundsEsteban Küber-2/+95
When a trait bound is not met and restricting a type parameter would make the restriction hold, use a structured suggestion pointing at an appropriate place (type param in param list or `where` clause). Account for opaque parameters where instead of suggesting extending the `where` clause, we suggest appending the new restriction: `fn foo(impl Trait + UnmetTrait)`.
