Add current version of BTreeMap unit tests #1

Thanks! However, I am not sure if we should duplicate all these tests on the Miri side. Does this cover anything that https://github.com/RalfJung/miri-test-libstd would not already cover? |
Obviously not, but I understand this is currently the only way to cover them with -Zmiri-track-raw-pointers, and I assumed this branch won't last long. |
This branch is part of a PR, I plan to merge it once rust-lang/rust#78597 lands.
You can set custom flags with https://github.com/RalfJung/miri-test-libstd through the |
The latest nightly via rsutup should install a Miri that supports the flag that also has the required stdlib fixes, so you should be able to use it for this purpose. |
Hm, that does not actually work as there seem to be int-ptr-casts soemwhere in argument parsing...

Ah, things are going through an |
I didn't notice rustup was stuck on rustfmt and not on miri. That makes life a lot easier… once we get that |
Fix no_std tests that load libc from the sysroot when download-rustc is enabled 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/rust#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` and some tool depends on a local change to `compiler`. --- See rust-lang/rust#108767 (comment) for why `no_std` is required for the MCVE test to fail; it's complicated and not particularly important. Fixes rust-lang/rust#108767.

Stop turning transmutes into discriminant reads in mir-opt Partially reverts #109612, as after #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.
CFI: Fix encode_ty: unexpected Param(B/#1) Fixes #111510 and complements #106547 by adding support for encoding type parameters and also by transforming trait objects' traits into their identities before emitting type checks.
…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.

better implementation of signed div_floor/ceil Tracking issue for signed `div_floor`/`div_ceil`: rust-lang/rust#88581.

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 ;
