…aces, r=jyn514 Only deduplicate stack traces for good path bugs Fixes rust-lang#106267 Restores backtraces for `bug!` and `delay_span_bug` after rust-lang#106056. Only `delay_good_path_bug` needed its backtraces to be deduplicated, since it spits out the backtrace where it was created when it's being emitted. Before: ``` error: internal compiler error: /home/ubuntu/rust2/compiler/rustc_middle/src/ty/relate.rs:638:13: var types encountered in super_relate_consts: Const { ty: usize, kind: Infer(Var(_#0c)) } Const { ty: usize, kind: Param(N/#1) } note: the compiler unexpectedly panicked. this is a bug. note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md note: rustc 1.68.0-dev running on x86_64-unknown-linux-gnu query stack during panic: #0 [typeck] type-checking `<impl at /home/ubuntu/test.rs:7:1: 7:34>::trigger` #1 [typeck_item_bodies] type-checking all item bodies #2 [analysis] running analysis passes on this crate end of query stack error: aborting due to 2 previous errors ``` Hmm... that's a little bare.

…u-se
Implement `SpecOptionPartialEq` for `cmp::Ordering`
Noticed as I continue to explore options for having code using `partial_cmp` optimize better.
Before:
```llvm
; Function Attrs: mustprogress nofree nosync nounwind willreturn uwtable
define noundef zeroext i1 `@ordering_eq(i8` noundef %0, i8 noundef %1) unnamed_addr #0 {
start:
%2 = icmp eq i8 %0, 2
br i1 %2, label %bb1.i, label %bb3.i
bb1.i: ; preds = %start
%3 = icmp eq i8 %1, 2
br label %"_ZN55_$LT$T$u20$as$u20$core..option..SpecOptionPartialEq$GT$2eq17hb7e7beacecde585fE.exit"
bb3.i: ; preds = %start
%.not.i = icmp ne i8 %1, 2
%4 = icmp eq i8 %0, %1
%spec.select.i = and i1 %.not.i, %4
br label %"_ZN55_$LT$T$u20$as$u20$core..option..SpecOptionPartialEq$GT$2eq17hb7e7beacecde585fE.exit"
"_ZN55_$LT$T$u20$as$u20$core..option..SpecOptionPartialEq$GT$2eq17hb7e7beacecde585fE.exit": ; preds = %bb1.i, %bb3.i
%.0.i = phi i1 [ %3, %bb1.i ], [ %spec.select.i, %bb3.i ]
ret i1 %.0.i
}
```
After:
```llvm
; Function Attrs: mustprogress nofree norecurse nosync nounwind readnone willreturn uwtable
define noundef zeroext i1 `@ordering_eq(i8` noundef %0, i8 noundef %1) unnamed_addr #1 {
start:
%2 = icmp eq i8 %0, %1
ret i1 %2
}
```
(Which <https://alive2.llvm.org/ce/z/-rop5r> says LLVM *could* just do itself, but there's probably an issue already open for that problem from when this was originally looked at for `Option<NonZeroU8>` and friends.)

To avoid having to re-parse the `rustc-dev.tar.xz` tarball every time, which is quite slow, this adds a new `build/host/ci-rustc/.rustc-dev-contents` cache file which stores only the names of files we need to copy into the sysroot. This also allows reverting the hack in rust-lang#110121; now that we only copy rustc-dev on-demand, we can correctly add the `Rustc` check artifacts into the sysroot, so that this works correctly even when `download-rustc` is forced to `true`. --- See rust-lang#108767 (comment) for why `no_std` is required for the MCVE test to fail; it's complicated and not particularly important. Fixes rust-lang#108767.

Stop turning transmutes into discriminant reads in mir-opt Partially reverts rust-lang#109612, as after rust-lang#109993 these aren't actually equivalent any more, and I'm no longer confident this was ever an improvement in the first place. Having this "simplification" meant that similar-looking code actually did somewhat different things. For example, ```rust pub unsafe fn demo1(x: std::cmp::Ordering) -> u8 { std::mem::transmute(x) } pub unsafe fn demo2(x: std::cmp::Ordering) -> i8 { std::mem::transmute(x) } ``` in nightly today is generating <https://rust.godbolt.org/z/dPK58zW18> ```llvm define noundef i8 `@_ZN7example5demo117h341ef313673d2ee6E(i8` noundef %x) unnamed_addr #0 { %0 = icmp uge i8 %x, -1 %1 = icmp ule i8 %x, 1 %2 = or i1 %0, %1 call void `@llvm.assume(i1` %2) ret i8 %x } define noundef i8 `@_ZN7example5demo217h5ad29f361a3f5700E(i8` noundef %0) unnamed_addr #0 { %x = alloca i8, align 1 store i8 %0, ptr %x, align 1 %1 = load i8, ptr %x, align 1, !range !2, !noundef !3 ret i8 %1 } ``` Which feels too different when the original code is essentially identical. --- Aside: that example is different *after* optimizations too: ```llvm define noundef i8 `@_ZN7example5demo117h341ef313673d2ee6E(i8` noundef returned %x) unnamed_addr #0 { %0 = add i8 %x, 1 %1 = icmp ult i8 %0, 3 tail call void `@llvm.assume(i1` %1) ret i8 %x } define noundef i8 `@_ZN7example5demo217h5ad29f361a3f5700E(i8` noundef returned %0) unnamed_addr #1 { ret i8 %0 } ``` so turning the `Transmute` into a `Discriminant` was arguably just making things worse, so leaving it alone instead -- and thus having less code in rustc -- seems clearly better.

…iler-errors Use `load`+`store` instead of `memcpy` for small integer arrays I was inspired by rust-lang#98892 to see whether, rather than making `mem::swap` do something smart in the library, we could update MIR assignments like `*_1 = *_2` to do something smarter than `memcpy` for sufficiently-small types that doing it inline is going to be better than a `memcpy` call in assembly anyway. After all, special code may help `mem::swap`, but if the "obvious" MIR can just result in the correct thing that helps everything -- other code like `mem::replace`, people doing it manually, and just passing around by value in general -- as well as makes MIR inlining happier since it doesn't need to deal with all the complicated library code if it just sees a couple assignments. LLVM will turn the short, known-length `memcpy`s into direct instructions in the backend, but that's too late for it to be able to remove `alloca`s. In general, replacing `memcpy`s with typed instructions is hard in the middle-end -- even for `memcpy.inline` where it knows it won't be a function call -- is hard [due to poison propagation issues](https://rust-lang.zulipchat.com/#narrow/stream/187780-t-compiler.2Fwg-llvm/topic/memcpy.20vs.20load-store.20for.20MIR.20assignments/near/360376712). So because we know more about the type invariants -- these are typed copies -- rustc can emit something more specific, allowing LLVM to `mem2reg` away the `alloca`s in some situations. rust-lang#52051 previously did something like this in the library for `mem::swap`, but it ended up regressing during enabling mir inlining (rust-lang@cbbf06b), so this has been suboptimal on stable for ≈5 releases now. The code in this PR is narrowly targeted at just integer arrays in LLVM, but works via a new method on the [`LayoutTypeMethods`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_codegen_ssa/traits/trait.LayoutTypeMethods.html) trait, so specific backends based on cg_ssa can enable this for more situations over time, as we find them. I don't want to try to bite off too much in this PR, though. (Transparent newtypes and simple things like the 3×usize `String` would be obvious candidates for a follow-up.) Codegen demonstrations: <https://llvm.godbolt.org/z/fK8hT9aqv> Before: ```llvm define void `@swap_rgb48_old(ptr` noalias nocapture noundef align 2 dereferenceable(6) %x, ptr noalias nocapture noundef align 2 dereferenceable(6) %y) unnamed_addr #1 { %a.i = alloca [3 x i16], align 2 call void `@llvm.lifetime.start.p0(i64` 6, ptr nonnull %a.i) call void `@llvm.memcpy.p0.p0.i64(ptr` noundef nonnull align 2 dereferenceable(6) %a.i, ptr noundef nonnull align 2 dereferenceable(6) %x, i64 6, i1 false) tail call void `@llvm.memcpy.p0.p0.i64(ptr` noundef nonnull align 2 dereferenceable(6) %x, ptr noundef nonnull align 2 dereferenceable(6) %y, i64 6, i1 false) call void `@llvm.memcpy.p0.p0.i64(ptr` noundef nonnull align 2 dereferenceable(6) %y, ptr noundef nonnull align 2 dereferenceable(6) %a.i, i64 6, i1 false) call void `@llvm.lifetime.end.p0(i64` 6, ptr nonnull %a.i) ret void } ``` Note it going to stack: ```nasm swap_rgb48_old: # `@swap_rgb48_old` movzx eax, word ptr [rdi + 4] mov word ptr [rsp - 4], ax mov eax, dword ptr [rdi] mov dword ptr [rsp - 8], eax movzx eax, word ptr [rsi + 4] mov word ptr [rdi + 4], ax mov eax, dword ptr [rsi] mov dword ptr [rdi], eax movzx eax, word ptr [rsp - 4] mov word ptr [rsi + 4], ax mov eax, dword ptr [rsp - 8] mov dword ptr [rsi], eax ret ``` Now: ```llvm define void `@swap_rgb48(ptr` noalias nocapture noundef align 2 dereferenceable(6) %x, ptr noalias nocapture noundef align 2 dereferenceable(6) %y) unnamed_addr #0 { start: %0 = load <3 x i16>, ptr %x, align 2 %1 = load <3 x i16>, ptr %y, align 2 store <3 x i16> %1, ptr %x, align 2 store <3 x i16> %0, ptr %y, align 2 ret void } ``` still lowers to `dword`+`word` operations, but has no stack traffic: ```nasm swap_rgb48: # `@swap_rgb48` mov eax, dword ptr [rdi] movzx ecx, word ptr [rdi + 4] movzx edx, word ptr [rsi + 4] mov r8d, dword ptr [rsi] mov dword ptr [rdi], r8d mov word ptr [rdi + 4], dx mov word ptr [rsi + 4], cx mov dword ptr [rsi], eax ret ``` And as a demonstration that this isn't just `mem::swap`, a `mem::replace` on a small array (since replace doesn't use swap since rust-lang#83022), which used to be `memcpy`s in LLVM changes in IR ```llvm define void `@replace_short_array(ptr` noalias nocapture noundef sret([3 x i32]) dereferenceable(12) %0, ptr noalias noundef align 4 dereferenceable(12) %r, ptr noalias nocapture noundef readonly dereferenceable(12) %v) unnamed_addr #0 { start: %1 = load <3 x i32>, ptr %r, align 4 store <3 x i32> %1, ptr %0, align 4 %2 = load <3 x i32>, ptr %v, align 4 store <3 x i32> %2, ptr %r, align 4 ret void } ``` but that lowers to reasonable `dword`+`qword` instructions still ```nasm replace_short_array: # `@replace_short_array` mov rax, rdi mov rcx, qword ptr [rsi] mov edi, dword ptr [rsi + 8] mov dword ptr [rax + 8], edi mov qword ptr [rax], rcx mov rcx, qword ptr [rdx] mov edx, dword ptr [rdx + 8] mov dword ptr [rsi + 8], edx mov qword ptr [rsi], rcx ret ```

…=xFrednet Fix tuple_array_conversions lint on nightly ``` changelog: ICE: [`tuple_array_conversions`]: Don't expect array length to always be usize ``` tl;dr: changed [`Const::eval_target_usize`](https://github.com/rust-lang/rust/blob/master/compiler/rustc_middle/src/ty/consts.rs#L359) to [`Consts::try_eval_target_usize`](https://github.com/rust-lang/rust/blob/master/compiler/rustc_middle/src/ty/consts.rs#L327) to get rid of ICE. I have encountered a problem with clippy: it caught ICE when working with a codebase that uses a lot of nightly features. Here's a (stripped) ICE info: ``` error: internal compiler error: /rustc/5c6a7e71cd66705c31c9af94077901a220f0870c/compiler/rustc_middle/src/ty/consts.rs:361:32: expected usize, got Const { ty: usize, kind: N/#1 } thread 'rustc' panicked at /rustc/5c6a7e71cd66705c31c9af94077901a220f0870c/compiler/rustc_errors/src/lib.rs:1635:9: Box<dyn Any> stack backtrace: ... 16: 0x110b9c590 - rustc_middle[449edf845976488d]::util::bug::bug_fmt 17: 0x102f76ae0 - clippy_lints[71754038dd04c2d2]::tuple_array_conversions::all_bindings_are_for_conv ... ``` I don't really know what's going on low-level-wise, but seems like this lin assumed that the length of the array can always be treated as `usize`, and *I assume* this doesn't play well with `feat(generic_const_exprs)`. I wasn't able to build a minimal reproducible example, but locally this fix does resolve the issue.

Make `TyKind::Adt`'s `Debug` impl be more pretty
Currently `{:?}` on `Ty` for a `TyKind::Adt` would print as `Adt(Foo, [])`. This PR changes it to be `Foo` when there are no generics or `Foo<T>`/`Foo<T, U>` when there _are_ generics. Example from debug log:
`├─0ms DEBUG rustc_hir_analysis::astconv return=Bar<T/#0, U/#1>`
I should have done this in my initial PR for a prettier TyKind: Debug impl but I thought I would need to be accessing generics_of to figure out where in the "path" the generics would have to go??? but no, adts literally only have a single place the generics can go (on the end). Feel a bit silly about this :)

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. ```

…r=Mark-Simulacrum lldb-formatters: Use StdSliceSyntheticProvider for &str &str has associated summary provider which correctly displays string values in debugger, but while working on rust-lang#124458 I've noticed that a &str inside an enum displays a blob of memory until a 0 is reached (as a c-string) which makes a very bizarre experience when debugging However there is already StdSliceSyntheticProvider which we use for other slices. This PR enables the same synthetic provider to be used for &str, however the summary provider is still fixed to return the string value I've added a test `debuginfo/strings-and-strs.rs` which prior to this PR would output the following in LLDB: ``` * thread #1, name = 'a', stop reason = breakpoint 1.1 frame #0: 0x0000555555556383 a`strings_and_strs::main::h1d2b5f9227b8767d at strings-and-strs.rs:47:5 44 let plain_str = "Hello"; 45 let str_in_struct = Foo { inner: "Hello" }; 46 let str_in_tuple = ("Hello", "World"); -> 47 zzz(); // #break 48 } 49 50 fn zzz() { (lldb) frame var (alloc::string::String) plain_string = "Hello" { vec = size=5 { [0] = 'H' [1] = 'e' [2] = 'l' [3] = 'l' [4] = 'o' } } (&str) plain_str = "Hello" { data_ptr = 0x0000555555557263 "HelloWorld\U00000001gdb_load_rust_pretty_printers.py" length = 5 } (strings_and_strs::Foo) str_in_struct = { inner = "Hello" { data_ptr = 0x0000555555557263 "HelloWorld\U00000001gdb_load_rust_pretty_printers.py" length = 5 } } ((&str, &str)) str_in_tuple = { 0 = "Hello" { data_ptr = 0x0000555555557263 "HelloWorld\U00000001gdb_load_rust_pretty_printers.py" length = 5 } 1 = "World" { data_ptr = 0x0000555555557268 "World\U00000001gdb_load_rust_pretty_printers.py" length = 5 } } ``` After this PR it would look the following way: ``` * thread #1, name = 'a', stop reason = breakpoint 1.1 frame #0: 0x0000555555556383 a`strings_and_strs::main::h1d2b5f9227b8767d at strings-and-strs.rs:47:5 44 let plain_str = "Hello"; 45 let str_in_struct = Foo { inner: "Hello" }; 46 let str_in_tuple = ("Hello", "World"); -> 47 zzz(); // #break 48 } 49 50 fn zzz() { (lldb) frame var (alloc::string::String) plain_string = "Hello" { vec = size=5 { [0] = 'H' [1] = 'e' [2] = 'l' [3] = 'l' [4] = 'o' } } (&str) plain_str = "Hello" { [0] = 'H' [1] = 'e' [2] = 'l' [3] = 'l' [4] = 'o' } (strings_and_strs::Foo) str_in_struct = { inner = "Hello" { [0] = 'H' [1] = 'e' [2] = 'l' [3] = 'l' [4] = 'o' } } ((&str, &str)) str_in_tuple = { 0 = "Hello" { [0] = 'H' [1] = 'e' [2] = 'l' [3] = 'l' [4] = 'o' } 1 = "World" { [0] = 'W' [1] = 'o' [2] = 'r' [3] = 'l' [4] = 'd' } } ```

…-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 = [ # ...

…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 |

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()
}
```

There's more that could be done but these were the lowest-hanging fruits that I saw.

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.

we get these declarations ``` ; opt level 0 declare x86_intrcc void @page_fault_handler(ptr byval([8 x i8]) align 8, i64) unnamed_addr #1 ; opt level > 0 declare x86_intrcc void @page_fault_handler(ptr noalias nocapture noundef byval([8 x i8]) align 8 dereferenceable(8), i64 noundef) unnamed_addr #1 ``` The space after `i64` in the original regex made the regex not match for opt level 0. Removing the space fixes the issue. ``` declare x86_intrcc void @page_fault_handler(ptr {{.*}}, i64 {{.*}}){{.*}}#[[ATTRS:[0-9]+]] ```
