2020-02-05Rollup merge of #68858 - ljedrz:collapse_stable_hash_foos, r=michaelwoeristerDylan DPC-27/+1
Merge item id stable hashing functions Supersedes https://github.com/rust-lang/rust/pull/67999 splitting out the pure cleanup bits, i.e. merging `hash_item_id`, `hash_impl_item_id` and `hash_trait_item_id` into a common `hash_reference_to_item`. r? @michaelwoerister
2020-02-05Rollup merge of #68840 - Centril:rec-lim-curr-crate, r=estebankDylan DPC-2/+2
On suggesting `#![recursion_limit = "X"]`, note current crate name This would have saved me much confusion e.g. when reading the log output in https://github.com/rust-lang/rust/pull/68788#issuecomment-581852191. r? @estebank

2020-02-04Auto merge of #68544 - Aaron1011:remove-overlapping-traits, r=estebankbors-13/+4
Remove the `overlapping_marker_traits` feature See #29864 This has been replaced by `#[feature(marker_trait_attr)]` A few notes: * Due to PR #68057 not yet being in the bootstrap compiler, it's necessary to continue using `#![feature(overlapping_marker_traits)]` under `#[cfg(bootstrap)]` to work around type inference issues. * I've updated tests that used `overlapping_marker_traits` to now use `marker_trait_attr` where applicable The test `src/test/ui/overlap-marker-trait.rs` doesn't make any sense now that `overlapping_marker_traits`, so I removed it. The test `src/test/ui/traits/overlap-permitted-for-marker-traits-neg.rs` now fails, since it's no longer possible to have multiple overlapping negative impls of `Send`. I believe that this is the behavior we want (assuming that `Send` is not going to become a `#[marker]` trait, so I renamed the test to `overlap-permitted-for-marker-traits-neg`

2020-02-04Auto merge of #68377 - estebank:fn-obligations-spans, r=oli-obkbors-126/+307
Tweak obligation error output - Point at arguments or output when fn obligations come from them, or ident when they don't - Point at `Sized` bound (fix #47990) - When object unsafe trait uses itself in associated item suggest using `Self` (fix #66424, fix #33375, partially address #38376, cc #61525) - Point at reason in object unsafe trait with `Self` in supertraits or `where`-clause (cc #40533, cc #68377) - On implicit type parameter `Sized` obligations, suggest `?Sized` (fix #57744, fix #46683)
2020-02-04Auto merge of #68708 - Mark-Simulacrum:stage0-step, r=pietroalbinibors-2/+0
Step stage0 to bootstrap from 1.42 This also includes a commit which fixes the rustfmt downloading logic to redownload when the rustfmt channel changes, and bumps rustfmt to a more recent version.
