…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 [email protected], 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()
}
```
