…ichton Fixes rust-lang#10877 There was another PR which attempted to fix this in the parser (rust-lang#11804) and which was closed due to inactivity. This PR modifies typeck instead (as suggested in rust-lang#11804), which indeed seems to be simpler than modifying the parser and allows for a better error message.

The `cmp::min` and `cmp::max` functions are not correct with partially ordered values. rust-lang#12712

This includes a change to the way lifetime names are generated. Say we figure that `[#0, 'a, 'b]` have to be the same lifetimes, then instead of just generating a new lifetime `'c` like before to replace them, we would reuse `'a`. This is done so that when the lifetime name comes from an impl, we don't give something that's completely off, and we don't have to do much work to figure out where the name came from. For example, for the following code snippet: ```rust struct Baz<'x> { bar: &'x int } impl<'x> Baz<'x> { fn baz1(&self) -> &int { self.bar } } ``` `[#1, 'x]` (where `#1` is BrAnon(1) and refers to lifetime of `&int`) have to be marked the same lifetime. With the old method, we would generate a new lifetime `'a` and suggest `fn baz1(&self) -> &'a int` or `fn baz1<'a>(&self) -> &'a int`, both of which are wrong.

…ariables Diagnostics such as the following ``` mismatched types: expected `core::result::Result<uint,()>`, found `core::option::Option<<generic #1>>` <anon>:6 let a: Result<uint, ()> = None; ^~~~ mismatched types: expected `&mut <generic #2>`, found `uint` <anon>:7 f(42u); ^~~ ``` tend to be fairly unappealing to new users. While specific type var IDs are valuable in diagnostics that deal with more than one such variable, in practice many messages only mention one. In those cases, leaving out the specific number makes the messages slightly less terrifying. In addition, type variables have been changed to use the type hole syntax `_` in diagnostics. With a variable ID, they're printed as `_#id` (e.g. `_#1`). In cases where the ID is left out, it's simply `_`. Integer and float variables have an additional suffix after the number, e.g. `_#1i` or `_#3f`.

…, r=nikomatsakis This PR aims to improve the readability of diagnostic messages that involve unresolved type variables. Currently, messages like the following: ```rust mismatched types: expected `core::result::Result<uint,()>`, found `core::option::Option<<generic #1>>` <anon>:6 let a: Result<uint, ()> = None; ^~~~ mismatched types: expected `&mut <generic #2>`, found `uint` <anon>:7 f(42u); ^~~ ``` tend to appear unapproachable to new users.

For integer variables, the syntax used is: ```rust mismatched types: expected `core::result::Result<uint, ()>`, found `core::option::Option<_#1i>` <anon>:6 let a: Result<uint, ()> = Some(1); ``` and float variables: ```rust mismatched types: expected `core::result::Result<uint, ()>`, found `core::option::Option<_#1f>` <anon>:6 let a: Result<uint, ()> = Some(0.5); ``` [0] https://twitter.com/coda/status/517713085465772032 Closes rust-lang#2632.

There is a hot path through `opt_normalize_projection_type`: - `try_start` does a cache lookup (#1). - The result is a `NormalizedTy`. - There are no unresolved type vars, so we call `complete`. - `complete` does *another* cache lookup (#2), then calls `SnapshotMap::insert`. - `insert` does *another* cache lookup (#3), inserting the same value that's already in the cache. This patch optimizes this hot path by introducing `complete_normalized`, for use when the value is known in advance to be a `NormalizedTy`. It always avoids lookup #2. Furthermore, if the `NormalizedTy`'s obligations are empty (the common case), we know that lookup #3 would be a no-op, so we avoid it, while inserting a Noop into the `SnapshotMap`'s undo log.

When encountering an unexisting method for a given trait where an associated function has the same name, suggest using the appropriate syntax, instead of using `help` text. When only one candidate is found, do not call it "candidate #1", just call it "the candidate".

Tweak output on E0599 for assoc fn used as method - Use suggestion instead of `help` when possible - Add primary span label - Remove incorrect `help` suggestion using incorrect syntax - Do not refer to only one possible candidate as `candidate #1`, refer to it as `the candidate`

…-box, r=eddyb [NLL] Dangly paths for box Special-case `Box` in `rustc_mir::borrow_check`. Since we know dropping a box will not access any `&mut` or `&` references, it is safe to model its destructor as only touching the contents *owned* by the box. ---- There are three main things going on here: 1. The first main thing, this PR is fixing a bug in NLL where `rustc` previously would issue a diagnostic error in a case like this: ```rust fn foo(x: Box<&mut i32>) -> &mut i32 { &mut **x } ``` such code was accepted by the AST-borrowck in the past, but NLL was rejecting it with the following message ([playground](https://play.rust-lang.org/?gist=13c5560f73bfb16d6dab3ceaad44c0f8&version=nightly&mode=release&edition=2015)) ``` error[E0597]: `**x` does not live long enough --> src/main.rs:3:40 | 3 | fn foo(x: Box<&mut i32>) -> &mut i32 { &mut **x } | ^^^^^^^^ - `**x` dropped here while still borrowed | | | borrowed value does not live long enough | note: borrowed value must be valid for the anonymous lifetime #1 defined on the function body at 3:1... --> src/main.rs:3:1 | 3 | fn foo(x: Box<&mut i32>) -> &mut i32 { &mut **x } | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ error: aborting due to previous error ``` 2. The second main thing: The reason such code was previously rejected was because NLL (MIR-borrowck) incorporates a fix for issue rust-lang#31567, where it models a destructor's execution as potentially accessing any borrows held by the thing being destructed. The tests with `Scribble` model this, showing that the compiler now catches such unsoundness. However, that fix for issue rust-lang#31567 is too strong, in that NLL (MIR-borrowck) includes `Box` as one of the types with a destructor that potentially accesses any borrows held by the box. This thus was the cause of the main remaining discrepancy between AST-borrowck and MIR-borrowck, as documented in issue rust-lang#45696, specifically in [the last example of this comment](rust-lang#45696 (comment)), which I have adapted into the `fn foo` shown above. We did close issue rust-lang#45696 back in December of 2017, but AFAICT that example was not fixed by PR rust-lang#46268. (And we did not include a test, etc etc.) This PR fixes that case, by trying to model the so-called `DerefPure` semantics of `Box<T>` when we traverse the type of the input to `visit_terminator_drop`. 3. The third main thing is that during a review of the first draft of this PR, @matthewjasper pointed out that the new traversal of `Box<T>` could cause the compiler to infinite loop. I have adjusted the PR to avoid this (by tracking what types we have previously seen), and added a much needed test of this somewhat odd scenario. (Its an odd scenario because the particular case only arises for things like `struct A(Box<A>);`, something which cannot be constructed in practice.) Fix rust-lang#45696.

bypass auto_da_alloc for metadata files This saves about 0.7% when rerunning the UI test suite. I.e. when the metadata files exist and will be overwritten. No improvements expected for a clean build. So it might show up in incr-patched perf results. ``` regular rename: Benchmark #1: touch src/tools/compiletest/src/main.rs ; RUSTC_WRAPPER="" schedtool -B -e ./x.py test src/test/ui Time (mean ± σ): 47.305 s ± 0.170 s [User: 1631.540 s, System: 412.648 s] Range (min … max): 47.125 s … 47.856 s 20 runs non-durable rename: Benchmark #1: touch src/tools/compiletest/src/main.rs ; RUSTC_WRAPPER="" schedtool -B -e ./x.py test src/test/ui Time (mean ± σ): 46.930 s ± 0.064 s [User: 1634.344 s, System: 396.038 s] Range (min … max): 46.759 s … 47.043 s 20 runs ``` There are more places that trigger auto_da_alloc behavior by overwriting existing files with O_TRUNC, but those are much harder to locate because `O_TRUNC` is set on `open()` but the writeback is triggered on `close()`. The latter is the part which shows up in profiles.

Specialize array cloning for Copy types Because after PR 86041, the optimizer no longer load-merges at the LLVM IR level, which might be part of the perf loss. (I'll run perf and see if this makes a difference.) Also I added a codegen test so this hopefully won't regress in future -- it passes on stable and with my change here, but not on the 2021-11-09 nightly.

Change prefetch to avoid deadlock Was abled to reproduce the deadlock in rust-lang#118205 and created a coredump when it happen. When looking at the backtraces I noticed that the prefetch of exported_symbols (Thread 17 frame 4) started after the "actual" exported_symbols (Thread 2 frame 18) but it also is working on some of the collect_crate_mono_items (Thread 17 frame12 ) that Thread 2 is blocked on resulting in a deadlock. This PR results in less parallell work that can be done at the same time but from what I can find we do not call the query exported_symbols from multiple places in the same join call any more. ```

…-codegen-tests, r=erikdesjardins,workingjubilee Repair several `riscv64gc-unknown-linux-gnu` codegen tests Together with joshua.zivkovic@codethink.co.uk, we've been starting to explore improving the state of the `riscv64gc-unknown-linux-gnu` target. Additionally, I'm looking to add support for this platform in [Ferrocene](https://github.com/ferrocene/ferrocene) ([Related PR](ferrocene/ferrocene#618)). While running the test suite, we noted several tests were failing. It appears that several of the riscv64gc-unknown-linux-gnu codegen tests have not been updated in some time and seem to have experienced a small amount of bitrot. After speaking with `@workingjubilee` (as I have little expertise in LLVM codegen) I believe these changes to be correct. ### `tests/codegen/riscv-abi/call-llvm-intrinsics.rs` I believe this change does not alter what the test is testing and is harmless. ### `tests/codegen/riscv-abi/riscv64-lp64d-abi.rs` The changes largely mirrors those from loongarch64: https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L13-L15 https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L153-L155 https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L259-L261 https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L263-L267 ### `tests/codegen/riscv-abi/riscv64-lp64f-lp64d-abi.rs` The changes largely mirror that from loongarch64 or llvm: https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L13-L26 https://github.com/rust-lang/llvm-project/blob/5399a24c66cb6164cf32280e7d300488c90d5765/clang/test/CodeGen/RISCV/riscv64-abi.c#L612-L617 ### `tests/ui/debuginfo/debuginfo-emit-llvm-ir-and-split-debuginfo.rs` The test is ignored since `-Csplit-debuginfo=unpacked` is not supported on this platform. Context can be found in rust-lang#120518. ## Reproducing the failures Using a `config.toml` with the following: ```toml # ... target = [ # ...

We get ours from [here](https://www.embecosm.com/resources/tool-chain-downloads/#riscv-linux). > > If you are using an old (20.04) Ubuntu container the compiler in the repositories (`gcc-riscv64-linux-gnu`) won't work!

…res, r=oli-obk Tell users not to file a bug when using internal library features Actually fixes rust-lang#97501. I don't think we should suppress the suggestion to add `#![feature(..)]`, though I guess I could be convinced otherwise. r? `@Nilstrieb` cc `@RalfJung` Didn't add a test b/c I don't think we test this for lang features either, but I can confirm it does work. ``` warning: the feature `core_intrinsics` is internal to the compiler or standard library --> /home/michael/test.rs:1:12 | 1 |

…raheemdev Optimize `Box::default` and `Arc::default` to construct more types in place Both the `Arc` and `Box` `Default` impls currently call `T::default()` before allocating, and then moving the resulting `T` into the allocation. Most `Default` impls are trivial, which should in theory allow LLVM to construct `T: Default` directly in the `Box` allocation when calling `<Box<T>>::default()`. However, the allocation may fail, which necessitates calling `T`'s destructor if it has one. If the destructor is non-trivial, then LLVM has a hard time proving that it's sound to elide, which makes it construct `T` on the stack first, and then copy it into the allocation. Change both of these impls to allocate first, and then call `T::default` into the uninitialized allocation, so that LLVM doesn't have to prove that it's sound to elide the destructor/initial stack copy. For example, given the following Rust code: ```rust #[derive(Default, Clone)] struct Foo { x: Vec<u8>, z: String, y: Vec<u8>, } #[no_mangle] pub fn src() -> Box<Foo> { Box::default() } ``` <details open> <summary>Before this PR:</summary> ```llvm `@__rust_no_alloc_shim_is_unstable` = external global i8 ;

…Kobzol shave 150ms off bootstrap This starts `git` commands inside `GitInfo`and the submodule updates in parallel. Git should already perform internal locking in cases where it needs to serialize a modification. ``` OLD Benchmark #1: ./x check core Time (mean ± σ): 608.7 ms ± 4.4 ms [User: 368.3 ms, System: 455.1 ms] Range (min … max): 602.3 ms … 618.8 ms 10 runs NEW Benchmark #1: ./x check core Time (mean ± σ): 462.8 ms ± 2.6 ms [User: 350.2 ms, System: 485.1 ms] Range (min … max): 457.5 ms … 465.6 ms 10 runs ``` This should help with the rust-analyzer setup which issues many individual `./x check` calls. There's more that could be done but these were the lowest-hanging fruits that I saw.

The failure output is: ``` SplitVectorOperand Op #1: t51: i32 = llvm.wasm.alltrue TargetConstant:i32<12408>, t50 rustc-LLVM ERROR: Do not know how to split this operator's operand! ```
