2019-03-08Rollup merge of #58984 - estebank:multi-treat-err-as-bug, r=oli-obkPietro Albini-5/+14
Teach `-Z treat-err-as-bug` to take a number of errors to emit `-Z treat-err-as-bug` will cause `rustc` to panic after the first error is reported, like previously. `-Z treat-err-as-bug=2` will cause `rustc` to panic after 2 errors have been reported. Fix #58983.

2019-02-14Rollup merge of #58378 - alexcrichton:incremental-lto, r=michaelwoeristerMazdak Farrokhzad-15/+1
rustc: Implement incremental "fat" LTO Currently the compiler will produce an error if both incremental compilation and full fat LTO is requested. With recent changes and the advent of incremental ThinLTO, however, all the hard work is already done for us and it's actually not too bad to remove this error! This commit updates the codegen backend to allow incremental full fat LTO. The semantics are that the input modules to LTO are all produce incrementally, but the final LTO step is always done unconditionally regardless of whether the inputs changed or not. The only real incremental win we could have here is if zero of the input modules changed, but that's so rare it's unlikely to be worthwhile to implement such a code path. cc #57968 cc rust-lang/cargo#6643

2019-02-13Rollup merge of #58273 - taiki-e:rename-dependency, r=matthewjasperMazdak Farrokhzad-4/+3
Rename rustc_errors dependency in rust 2018 crates I think this is a better solution than `use rustc_errors as errors` in `lib.rs` and `use crate::errors` in modules. Related: rust-lang/cargo#5653 cc #58099 r? @Centril
2019-02-13Rollup merge of #58057 - michaelwoerister:stabilize-xlto, r=alexcrichtonMazdak Farrokhzad-22/+24
Stabilize linker-plugin based LTO (aka cross-language LTO) This PR stabilizes [linker plugin based LTO](https://github.com/rust-lang/rust/issues/49879), also known as "cross-language LTO" because it allows for doing inlining and other optimizations across language boundaries in mixed Rust/C/C++ projects. As described in the tracking issue, it works by making `rustc` emit LLVM bitcode instead of machine code, the same as `clang` does. A linker with the proper plugin (like LLD) can then run (Thin)LTO across all modules. The feature has been implemented over a number of pull requests and there are various [codegen](https://github.com/rust-lang/rust/blob/master/src/test/codegen/no-dllimport-w-cross-lang-lto.rs) and [run](https://github.com/rust-lang/rust/tree/master/src/test/run-make-fulldeps/cross-lang-lto-clang)-[make](https://github.com/rust-lang/rust/tree/master/src/test/run-make-fulldeps/cross-lang-lto-upstream-rlibs) [tests](https://github.com/rust-lang/rust/tree/master/src/test/run-make-fulldeps/cross-lang-lto) that make sure that it keeps working. It also works for building big projects like [Firefox](https://treeherder.mozilla.org/#/jobs?repo=try&revision=2ce2d5ddcea6fbff790503eac406954e469b2f5d). The PR makes the feature available under the `-C linker-plugin-lto` flag. As discussed in the tracking issue it is not cross-language specific and also not LLD specific. `-C linker-plugin-lto` is descriptive of what it does. If someone has a better name, let me know `:)`

2019-02-06Auto merge of #56123 - oli-obk:import_miri_from_future, r=eddybbors-0/+2
Add a forever unstable opt-out of const qualification checks r? @eddyb cc @RalfJung @Centril basically a forever unstable way to screw with const things in horribly unsafe, unsound and incoherent ways. Note that this does *not* affect miri except by maybe violating assumptions that miri makes. But there's no change in how miri evaluates things.
