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 } ```

There were a series of unfortunate interactions here. Here's an MCVE of the test this fixes (committed as `tests/ui/meta/no_std-extern-libc.rs`): ```rust #![crate_type = "lib"] #![no_std] #![feature(rustc_private)] extern crate libc; ``` Before, this would give an error about duplicate versions of libc: ``` error[E0464]: multiple candidates for `rlib` dependency `libc` found --> fake-test-src-base/allocator/no_std-alloc-error-handler-default.rs:15:1 | LL | extern crate libc; | ^^^^^^^^^^^^^^^^^^ | = note: candidate #1: /home/gh-jyn514/rust/build/aarch64-unknown-linux-gnu/stage2/lib/rustlib/aarch64-unknown-linux-gnu/lib/liblibc-358db1024b7d9957.rlib = note: candidate rust-lang#2: /home/gh-jyn514/rust/build/aarch64-unknown-linux-gnu/stage2/lib/rustlib/aarch64-unknown-linux-gnu/lib/liblibc-ebc478710122a279.rmeta ``` Both these versions were downloaded from CI, but one came from the `rust-std` component and one came from `rustc-dev`: ``` ; tar -tf build/cache/f2d9a3d0771504f1ae776226a5799dcb4408a91a/rust-std-nightly-x86_64-unknown-linux-gnu.tar.xz | grep liblibc rust-std-nightly-x86_64-unknown-linux-gnu/rust-std-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-unknown-linux-gnu/lib/liblibc-68a2d9e195dd6ed2.rlib ; tar -tf build/cache/f2d9a3d0771504f1ae776226a5799dcb4408a91a/rustc-dev-nightly-x86_64-unknown-linux-gnu.tar.xz | grep liblibc rustc-dev-nightly-x86_64-unknown-linux-gnu/rustc-dev/lib/rustlib/x86_64-unknown-linux-gnu/lib/liblibc-f226c9fbdd92a0fd.rmeta ``` The fix was to only copy files from `rust-std` unless a Step explicitly requests for the `rustc-dev` components to be available by calling `builder.ensure(compile::Rustc)`. 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.

…=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.

…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.

…res, r=oli-obk Tell users not to file a bug when using internal library features Actually fixes rust-lang#97501.

…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! ```
