Upgrade librustc_macros dependencies Passed tests on Linux.
2019-10-06Rollup merge of #65095 - GuillaumeGomez:sort-librustc_passes-err-codes, r=varkorTyler Mandry-162/+161
Sort error codes in librustc_passes This is just a little cleanup.
2019-10-06Auto merge of #64564 - jonas-schievink:cowardly-default, r=nikomatsakisbors-45/+268
Deny specializing items not in the parent impl Part of https://github.com/rust-lang/rust/issues/29661 (https://github.com/rust-lang/rfcs/pull/2532). At least sort of? This was discussed in https://github.com/rust-lang/rust/pull/61812#discussion_r300504114 and is needed for that PR to make progress (fixing an unsoundness). One annoyance with doing this is that it sometimes requires users to copy-paste a provided trait method into an impl just to mark it `default` (ie. there is no syntax to forward this impl method to the provided trait method). cc @Centril and @arielb1

2019-10-06redesign of the interface to the unikernel HermitCoreStefan Lankes-451/+2388
- the old interface between HermitCore and the Rust Standard Library based on a small C library (newlib) - remove this interface and call directly the unikernel - remove the dependency to the HermitCore linker - use rust-lld as linker

2019-10-06Auto merge of #65043 - Aaron1011:fix/reexport-determinism, r=petrochenkovbors-29/+19
Make re-export collection deterministic Fixes https://github.com/rust-lang/rust/issues/65036 Previously, we were using an `FxHashMap` to collect module re-exports. However, re-exports end up getting serialized into crate metadata, which means that metadata generation was non-deterministic. This resulted in spurious error messages changes (e.g. PR #64906) due to pretty-printing implicitly depending on the order of re-exports when computing the proper path to show to the user. See #65042 for a long-term strategy to detect this kind of issue

2019-10-05Rollup merge of #65151 - tmandry:revert-emscripten-upgrade, r=tmandryTyler Mandry-376/+537
Revert #63649 - "Upgrade Emscripten targets to use upstream LLVM backend" This change caused the runtime of the linux-asmjs builder to nearly double from 2+ hours to about 4 hours, which happens to be the bors timeout. (It made it in barely under 4 hours when it was merged.) This is causing timeouts on all new changes. This reverts commit 7870050796e5904a0fc85ecbe6fa6dde1cfe0c91, reversing changes made to 2e7244807a7878f6eca3eb7d97ae9b413aa49014.
2019-10-05Rollup merge of #65130 - davidtwco:rfc-2008-improper-ctypes, r=petrochenkovTyler Mandry-0/+175
lint: extern non-exhaustive types are improper This PR makes the `improper_ctype` lint trigger for non-exhaustive types when those types aren't defined in the current crate, as per [this comment](https://github.com/rust-lang/rust/issues/44109#issuecomment-537583344). cc @Centril

2019-10-05Rollup merge of #65123 - Centril:mac-invoc-in-mut-pat, r=estebankTyler Mandry-1/+76

2019-10-05Rollup merge of #65106 - Mark-Simulacrum:unused-attr-allow, r=CentrilTyler Mandry-0/+2
Allow unused attributes to avoid incremental bug cc #65023 This isn't labeled as fixing that issue because it's not really a fix, just a patch.
2019-10-05Rollup merge of #65105 - Mark-Simulacrum:split-librustc, r=nikomatsakisTyler Mandry-229/+237
Split out some passes from librustc This is just moving them out to librustc_passes -- I've not measured compile time or run time. I don't expect any significant impact, but this seems prudent regardless.

std: Reduce checks for `feature = "backtrace"` This is a stylistic change to libstd to reduce the number of checks of `feature = "backtrace"` now that we unconditionally depend on the `backtrace` crate and rely on it having an empty implementation. otherwise.
