2018-10-20Auto merge of #55014 - ljedrz:lazyboye_unwraps, r=matthewjasperbors-1/+1
Prefer unwrap_or_else to unwrap_or in case of function calls/allocations The contents of `unwrap_or` are evaluated eagerly, so it's not a good pick in case of function calls and allocations. This PR also changes a few `unwrap_or`s with `unwrap_or_default`. An added bonus is that in some cases this change also reveals if the object it's called on is an `Option` or a `Result` (based on whether the closure takes an argument).

diagnostics. This is mainly intended for `rustc` developers who want to see a diagnostic in its original context in the control flow. Two uses cases for that are: * `-Z treat-err-as-bug` which then allows extraction of a stack-trace to the origin of the error (a case that is so important that we make that flag imply this one, effectively). * `RUST_LOG=... rustc`, in which case it is often useful to see the logging statements that occurred immediately prior to the point where the diagnostic was signalled. Drive-by: Added some documentation pointing future devs at HandlerFlags, and documented the fields of `HandlerFlags` itself.

2018-09-14Rollup merge of #54024 - alexcrichton:compile-to-wasm, r=petrochenkovkennytm-1/+1
Fix compiling some rustc crates to wasm I was dabbling recently seeing what it would take to compile `rustfmt` to the `wasm32-unknown-unknown` target and it turns out not much effort is needed! Currently `rustfmt` depends on a few rustc crates published to crates.io, so this commit touches up those crates to compile for wasm themselves. Notably: * The `rustc_data_structures` crate's `flock` implementation is stubbed out to unconditionally return errors on unsupported platforms. * The `rustc_errors` crate is extended to not do any locking for all non-windows platforms. In both of these cases if we port the compiler to new platforms the functionality isn't critical but will be discovered over time as it comes up, so this hopefully doesn't make it too too hard to compile to new platforms!

2018-07-30rustc: Disallow machine applicability in foreign macrosAlex Crichton-19/+64
Recent changes to lints disallowed lints from being emitted against code located in foreign macros, except for future-incompatible lints. For a future incompatible lint, however, the automatic suggestions may not be applicable! This commit updates this code path to force all applicability suggestions made to foreign macros to never be `MachineApplicable`. This should avoid rustfix actually attempting fixing these suggestions, causing non-compiling code to be produced. Closes rust-lang/cargo#5799

2018-07-27Auto merge of #52681 - pnkfelix:z-borrowck-migrate, r=nikomatsakisbors-19/+19
Add `-Z borrowck=migrate` This adds `-Z borrowck=migrate`, which represents the way we want to migrate to NLL under Rust versions to come. It also hooks this new mode into `--edition 2018`, which means we're officially turning NLL on in the 2018 edition. The basic idea of `-Z borrowck=migrate` that there are cases where NLL is fixing old soundness bugs in the borrow-checker, but in order to avoid just breaking code by immediately rejecting the programs that hit those soundness bugs, we instead use the following strategy: If your code is accepted by NLL, then we accept it. If your code is rejected by both NLL and the old AST-borrowck, then we reject it. If your code is rejected by NLL but accepted by the old AST-borrowck, then we emit the new NLL errors as **warnings**. These warnings will be turned into hard errors in the future, and they say so in these diagnostics. Fix #46908
