Made it so that what passes are used is passed onto the renderer so it can intelligently deal with private modules.
This is the only free function not part of the trait.
Changed `rustdoc` so that if we do not have the `strip-private` pass enabled private modules will be included in the generated documentation I added this because it is useful to be able to read the documentation in the very nice `rustdoc` web interface when doing internal work on a project. In this case we want the `rustdoc` to include modules that are hidden from consumers. Since this is not currently possible I added it here.
'Numeric' is the proper name of the unicode character class, and this frees up the word 'digit' for ascii use in libcore. Since I'm going to rename `Char::is_digit_radix` to `is_digit`, I am not leaving a deprecated method in place, because that would just cause name clashes, as both `Char` and `UnicodeChar` are in the prelude. [breaking-change]
This fits the naming of `to_digit` and `from_digit`. Leave the old name deprecated.
"bytes" is redundant. Deprecate the old.
Missing method to pair with len_utf8.
For now we are preferring free functions for primitive ctors, so they are marked 'unstable' pending final decision. The methods on `Char` are 'deprecated'.
Prefer the methods.
The `Char` trait itself may go away in favor of primitive inherent methods. Still some questions about whether the preconditions are following the final error handling conventions.
Methods on primitmive Copy types generally should take `self`. [breaking-change]
[breaking-change]
Extension traits for primitive types should be by-value. [breaking-change]
Free functions deprecated. UnicodeChar experimental pending final decisions about prelude.

…-Simulacrum
Optimise align_offset for stride=1 further
`stride == 1` case can be computed more efficiently through `-p (mod
a)`. That, then translates to a nice and short sequence of LLVM
instructions:
%address = ptrtoint i8* %p to i64
%negptr = sub i64 0, %address
%offset = and i64 %negptr, %a_minus_one
And produces pretty much ideal code-gen when this function is used in
isolation.
Typical use of this function will, however, involve use of
the result to offset a pointer, i.e.
%aligned = getelementptr inbounds i8, i8* %p, i64 %offset
This still looks very good, but LLVM does not really translate that to
what would be considered ideal machine code (on any target). For example
that's the codegen we obtain for an unknown alignment:
; x86_64
dec rsi
mov rax, rdi
neg rax
and rax, rsi
add rax, rdi
In particular negating a pointer is not something that’s going to be
optimised for in the design of CISC architectures like x86_64. They
are much better at offsetting pointers. And so we’d love to utilize this
ability and produce code that's more like this:
; x86_64
lea rax, [rsi + rdi - 1]
neg rsi
and rax, rsi
To achieve this we need to give LLVM an opportunity to apply its
various peep-hole optimisations that it does during DAG selection. In
particular, the `and` instruction appears to be a major inhibitor here.
We cannot, sadly, get rid of this load-bearing operation, but we can
reorder operations such that LLVM has more to work with around this
instruction.
One such ordering is proposed in rust-lang#75579 and results in LLVM IR that
looks broadly like this:
; using add enables `lea` and similar CISCisms
%offset_ptr = add i64 %address, %a_minus_one
%mask = sub i64 0, %a
%masked = and i64 %offset_ptr, %mask
; can be folded with `gepi` that may follow
%offset = sub i64 %masked, %address
…and generates the intended x86_64 machine code.
One might also wonder how the increased amount of code would impact a
RISC target. Turns out not much:
; aarch64 previous ; aarch64 new
sub x8, x1, #1 add x8, x1, x0
neg x9, x0 sub x8, x8, #1
and x8, x9, x8 neg x9, x1
add x0, x0, x8 and x0, x8, x9
(and similarly for ppc, sparc, mips, riscv, etc)
The only target that seems to do worse is… wasm32.
Onto actual measurements – the best way to evaluate snipets like these
is to use llvm-mca. Much like Aarch64 assembly would allow to suspect,
there isn’t any performance difference to be found. Both snippets
execute in same number of cycles for the CPUs I tried. On x86_64,
we get throughput improvement of >50%!
Fixes rust-lang#75579

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.

Otherwise, we can get into a situation where you have a subtype obligation `#1 <: #2` pending, #1 is constrained by `check_casts`, but #2` is unaffected. Co-authored-by: Niko Matsakis <[email protected]>

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. Example on current nightly: <https://play.rust-lang.org/?version=nightly&mode=release&edition=2021&gist=1f52d46fb8fc3ca3ac9f097390085ffa> ```rust type T = u8; const N: usize = 3; pub fn demo_clone(x: &[T; N]) -> [T; N] { x.clone() } pub fn demo_copy(x: &[T; N]) -> [T; N] { *x } ``` ```llvm-ir ; playground::demo_clone ; Function Attrs: mustprogress nofree nosync nounwind nonlazybind uwtable willreturn define i24 `@_ZN10playground10demo_clone17h98a4f11453d1a753E([3` x i8]* noalias nocapture readonly align 1 dereferenceable(3) %x) unnamed_addr #0 personality i32 (i32, i32, i64, %"unwind::libunwind::_Unwind_Exception"*, %"unwind::libunwind::_Unwind_Context"*)* `@rust_eh_personality` { start: %0 = getelementptr [3 x i8], [3 x i8]* %x, i64 0, i64 0 %1 = getelementptr inbounds [3 x i8], [3 x i8]* %x, i64 0, i64 1 %.val.i.i.i.i.i.i.i.i.i = load i8, i8* %0, align 1, !alias.scope !2, !noalias !9 %2 = getelementptr inbounds [3 x i8], [3 x i8]* %x, i64 0, i64 2 %.val.i.i.i.i.i.1.i.i.i.i = load i8, i8* %1, align 1, !alias.scope !2, !noalias !20 %.val.i.i.i.i.i.2.i.i.i.i = load i8, i8* %2, align 1, !alias.scope !2, !noalias !23 %array.sroa.6.0.insert.ext.i.i.i.i = zext i8 %.val.i.i.i.i.i.2.i.i.i.i to i32 %array.sroa.6.0.insert.shift.i.i.i.i = shl nuw nsw i32 %array.sroa.6.0.insert.ext.i.i.i.i, 16 %array.sroa.5.0.insert.ext.i.i.i.i = zext i8 %.val.i.i.i.i.i.1.i.i.i.i to i32 %array.sroa.5.0.insert.shift.i.i.i.i = shl nuw nsw i32 %array.sroa.5.0.insert.ext.i.i.i.i, 8 %array.sroa.0.0.insert.ext.i.i.i.i = zext i8 %.val.i.i.i.i.i.i.i.i.i to i32 %array.sroa.5.0.insert.insert.i.i.i.i = or i32 %array.sroa.5.0.insert.shift.i.i.i.i, %array.sroa.0.0.insert.ext.i.i.i.i %array.sroa.0.0.insert.insert.i.i.i.i = or i32 %array.sroa.5.0.insert.insert.i.i.i.i, %array.sroa.6.0.insert.shift.i.i.i.i %.sroa.4.0.extract.trunc.i.i.i.i = trunc i32 %array.sroa.0.0.insert.insert.i.i.i.i to i24 ret i24 %.sroa.4.0.extract.trunc.i.i.i.i } ; playground::demo_copy ; Function Attrs: mustprogress nofree norecurse nosync nounwind nonlazybind readonly uwtable willreturn define i24 `@_ZN10playground9demo_copy17h7817453f9291d746E([3` x i8]* noalias nocapture readonly align 1 dereferenceable(3) %x) unnamed_addr #1 { start: %.sroa.0.0..sroa_cast = bitcast [3 x i8]* %x to i24* %.sroa.0.0.copyload = load i24, i24* %.sroa.0.0..sroa_cast, align 1 ret i24 %.sroa.0.0.copyload } ```

…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 ```

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 [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()
}
```

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