ci: Remove x86_64-gnu-incremental builder 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 directory contains the source code of the rust project, including:
rustcand its testslibstd- Various submodules for tools, like rustdoc, rls, etc.
For more information on how various parts of the compiler work, see the rustc guide.
