[beta] Processing merged backports #50127

alexcrichton · 2018-04-20T20:34:28Z

This is a backport of the following PRs:

If the compiler docs aren't going to include the test crate then it may as well be included with std.

…e feature list These are already stabilized in 1.26.

In intercrate mode, if we determine that a particular `T: Trait` is unknowable, we sometimes also go and get extra causal information. An errant `?` was causing us to propagate an error found in that process out as if `T: Trait` was not unknowable but rather not provable. This led to an ICE.

This builder is starting to time out frequently causing PRs to bounce and otherwise doesn't seem to be catching too many bugs, so this commit removes it entirely. We've had a number of timeouts in the last few weeks related to this builder: * https://travis-ci.org/rust-lang/rust/jobs/360947582 * https://travis-ci.org/rust-lang/rust/jobs/360464190 * https://travis-ci.org/rust-lang/rust/jobs/359946975 * https://travis-ci.org/rust-lang/rust/jobs/361213241 * https://travis-ci.org/rust-lang/rust/jobs/362346279 * https://travis-ci.org/rust-lang/rust/jobs/362072331 On a good run this builder takes about 2h15m, which is already too long for Travis and the variable build times end up pushing it beyond the 3h limit occasionally. The timeouts here are somewhat expected in that an incrementally compiled rustc compiler isn't optimized like a normal rustc, disallowing inlining between codegen units and losing lots of optimization opportunities.

This is running into #49889 so I'm going to apply the workaround listed in #49891, cc @cuviper and @michaelwoerister

This commit papers over rust-lang#49889 (introducing a fixme pointing at rust-lang#50125) for a bug that was introduced with rust-lang#49695. This workaround is taken from rust-lang#49891.
