2020-04-03Rollup merge of #70595 - wesleywiser:remove_unused_discriminant_reads, r=oli-obkMazdak Farrokhzad-20/+71
Remove unused discriminant reads from MIR bodies Allow the `SimplifyLocals` pass to remove reads of discriminants if the read is never used. Fixes #70531 r? @oli-obk
2020-04-03Rollup merge of #70487 - Mark-Simulacrum:float-unchecked-casts, r=SimonSapinMazdak Farrokhzad-22/+33
Stabilize float::to_int_unchecked This renames and stabilizes unsafe floating point to integer casts, which are intended to be the substitute for the currently unsound `as` behavior, once that changes to safe-but-slower saturating casts. As such, I believe this also likely unblocks #10184 (our oldest I-unsound issue!), as once this rolls out to stable it would be far easier IMO to change the behavior of `as` to be safe by default. This does not stabilize the trait or the associated method, as they are deemed internal implementation details (and consumers should not, generally, want to expose them, as in practice all callers likely know statically/without generics what the return type is). Closes #67058

2020-04-02Rollup merge of #70681 - rcoh:russell/70677-raw-str-panic, r=petrochenkovMazdak Farrokhzad-1/+49
Handle unterminated raw strings with no #s properly The modified code to handle parsing raw strings didn't properly account for the case where there was no "#" on either end and erroneously reported this strings as complete. This lead to a panic trying to read off the end of the file. Fixes #70677 r? @petrochenkov cc @Centril

r=eddyb add `STILL_FURTHER_SPECIALIZABLE` flag Contributes to #70285. This PR adds a `STILL_FURTHER_SPECIALIZABLE` flag to `TypeFlags` which replaces `needs_infer` and `needs_subst` in `Instance::resolve` and `assemble_candidates_from_impls`. r? @eddyb
2020-04-02Rollup merge of #70634 - Centril:import-directly, r=Mark-SimulacrumMazdak Farrokhzad-468/+414
Remove some reexports in `rustc_middle` This will help get these imports out of the way of detecting the true dependencies in and out to `rustc_middle`, thereby helping future work towards https://github.com/rust-lang/rust/issues/65031.

2020-04-02Rollup merge of #70421 - Centril:recover-const-async-fn-ptr, r=estebankMazdak Farrokhzad-23/+215
parse: recover on `const fn()` / `async fn()` Recover on `const fn()` and `async fn()` function pointers, suggesting to remove the qualifier. For example: ``` error: an `fn` pointer type cannot be `async` --> $DIR/recover-const-async-fn-ptr.rs:6:11 | LL | type T3 = async fn(); | -----^^^^^ | | | `async` because of this | help: remove the `async` qualifier ``` r? @estebank
2020-04-02Rollup merge of #70281 - xfix:infallible-hash, r=dtolnayMazdak Farrokhzad-0/+8
Implement Hash for Infallible https://www.reddit.com/r/rust/comments/fmllgx/never_crate_stable_alternative_to/ lists not implementing `Hash` as a reason for the `never` crate. I see no reason not to implement `Hash` for `Infallible`, so might as well do it. No changes necessary for `!`, because `!` already implements `Hash` (see https://github.com/rust-lang/rust/pull/51404).

2020-04-02Auto merge of #70628 - pietroalbini:gha-multiple-tries, r=Mark-Simulacrumbors-0/+1
GHA: enable running multiple try builds at the same time While for auto, try and PR builds we only want the latest commit to be tested, that's not true for try builds: each commit pushed to the branch is a different PR being tested, and we want multiple PRs to be tested in parallel if there is enough demand. Fixes #70569

2020-04-02Auto merge of #70362 - TimDiekmann:alloc-overhaul, r=Amanieubors-1619/+1445
Overhaul of the `AllocRef` trait to match allocator-wg's latest consens; Take 2 GitHub won't let me reopen #69889 so I make a new PR. In addition to #69889 this fixes the unsoundness of `RawVec::into_box` when using allocators supporting overallocating. Also it uses `MemoryBlock` in `AllocRef` to unify `_in_place` methods by passing `&mut MemoryBlock`. Additionally, `RawVec` now checks for `size_of::<T>()` again and ignore every ZST. The internal capacity of `RawVec` isn't used by ZSTs anymore, as `into_box` now requires a length to be specified. r? @Amanieu fixes rust-lang/wg-allocators#38 fixes rust-lang/wg-allocators#41 fixes rust-lang/wg-allocators#44 fixes rust-lang/wg-allocators#51

2020-04-01Rollup merge of #70662 - eddyb:compiletest-stdout-fix, r=Mark-SimulacrumDylan DPC-8/+4
compiletest: don't use `std::io::stdout()`, as it bypasses `set_print`. This PR undoes a change made during #69916, which became unnecessary during review but was left in by accident, and which isn't correct due to `libtest` using `std::io::set_print`, which overwrites the `println!` behavior but *not* `writeln!(std::io::stdout(), ...)`. The effect of using `writeln!(std::io::stdout(), ...)` was that the diff output would show *while* running the tests, instead of at the end, when failing tests are listed. r? @Mark-Simulacrum cc @oli-obk

2020-04-01Rollup merge of #70626 - pietroalbini:remove-webrender-cargotest, ↵Dylan DPC-7/+0
r=Mark-Simulacrum cargotest: remove webrender The current webrender commit occasionally fails without a reason, and the latest webrender commit is missing a dependency on our Windows builders. It's not worth installing an extra dependency for cargotest, and the spurious failure makes keeping this test not worth it. r? @Mark-Simulacrum
