Integrate context into the memorial to Anna This came up after I reviewed https://github.com/rust-lang/rust/pull/87298, but I didn't propose this in time before that PR was merged. If y'all feel this is too much churn on the file, no worries, feel free to close, but I felt this was a more fitting integration of the memorial into the test suite. CC ``@boringcactus.``

Fix ICE in `diagnostic_hir_wf_check` Fixes #87495. The [documentation for `ObligationCauseCode::WellFormed`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_infer/traits/enum.ObligationCauseCode.html#variant.WellFormed) says that > it is always correct [...] to specify `WellFormed(None)` instead of `WellFormed(Some(...))`, which seems to have caused the issue here, as `diagnostic_hir_wf_check` does not expect to be called with an associated constant and will ICE: https://github.com/rust-lang/rust/blob/fd853c00e255559255885aadff9e93a1760c8728/compiler/rustc_typeck/src/hir_wf_check.rs#L131-L134 Therefore, I have changed `check_associated_item()` to pass a `WellFormed(None)` for associated constants. r? ``@Aaron1011``
2021-07-28Rollup merge of #87513 - hudson-ayers:bootstrap-py-fix, r=jyn514Yuki Okushi-1/+1
bootstrap.py: change `git log` option to indicate desired behavior When determining which LLVM artifacts to download, bootstrap.py calls: `git log --author=bors --format=%H -n1 -m --first-parent -- src/llvm-project src/bootstrap/download-ci-llvm-stamp src/version`. However, the `-m` option has no effect, per the `git log` help: > -m > This option makes diff output for merge commits to be shown in the > default format. -m will produce the output only if -p is given as > well. The default format could be changed using log.diffMerges > configuration parameter, which default value is separate. Accordingly, this commit removes use of the -m option in favor of ~~`--diff-merges=off`~~ `--no-patch`, since no diff information is needed, and in fact the presence of a diff breaks the command. Tested using git 2.32, this does not change the output of the command. The motivation for this change is that some patched versions of git change the behavior of the `-m` flag to imply `-p`, rather than to do nothing unless `-p` is passed. These patched versions of git lead to this script not working. Google's corp-provided git is one such example.

2021-07-28Rollup merge of #87443 - jyn514:submodules-take-n, r=jyn514Yuki Okushi-18/+37
Don't treat git repos as non-existent when `ignore_git` is set The new submodule handling depends on `is_git()` to be accurate to decide whether it should handle submodules at all or not. Unfortunately, `is_git()` treated "this directory does not have a git repository" and "this repository should not be used for SHA/version/commit date info" the same. This changes it to distinguish the two. To clarify: ignore_get is set by default whenever channel == "dev", which it is by default whenever you're compiling locally. So basically everyone would hit this, not just people who had explicitly configured ignore_git. Here's an example of an error this fixes: ``` $ x build Updating only changed submodules Submodules updated in 0.01 seconds Finished dev [unoptimized + debuginfo] target(s) in 0.17s warning: x.py has made several changes recently you may want to look at help: consider looking at the changes in `src/bootstrap/CHANGELOG.md` note: to silence this warning, add `changelog-seen = 2` at the top of `config.toml` Building stage0 std artifacts (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu) Finished release [optimized] target(s) in 0.16s Copying stage0 std from stage0 (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu / x86_64-unknown-linux-gnu) Building LLVM for x86_64-unknown-linux-gnu detected home dir change, cleaning out entire build directory running: "cmake" "/home/joshua/rustc3/src/llvm-project/llvm" "-G" "Ninja" "-DLLVM_ENABLE_ASSERTIONS=OFF" "-DLLVM_TARGETS_TO_BUILD=AArch64;ARM;BPF;Hexagon;MSP430;Mips;NVPTX;PowerPC;RISCV;Sparc;SystemZ;WebAssembly;X86" "-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=AVR" "-DLLVM_INCLUDE_EXAMPLES=OFF" "-DLLVM_INCLUDE_DOCS=OFF" "-DLLVM_INCLUDE_BENCHMARKS=OFF" "-DLLVM_ENABLE_TERMINFO=OFF" "-DLLVM_ENABLE_LIBEDIT=OFF" "-DLLVM_ENABLE_BINDINGS=OFF" "-DLLVM_ENABLE_Z3_SOLVER=OFF" "-DLLVM_PARALLEL_COMPILE_JOBS=48" "-DLLVM_TARGET_ARCH=x86_64" "-DLLVM_DEFAULT_TARGET_TRIPLE=x86_64-unknown-linux-gnu" "-DLLVM_ENABLE_ZLIB=ON" "-DLLVM_ENABLE_LIBXML2=OFF" "-DLLVM_VERSION_SUFFIX=-rust-dev" "-DCMAKE_INSTALL_MESSAGE=LAZY" "-DCMAKE_C_COMPILER=gcc" "-DCMAKE_CXX_COMPILER=g++" "-DCMAKE_ASM_COMPILER=gcc" "-DCMAKE_C_FLAGS=-ffunction-sections -fdata-sections -fPIC -m64" "-DCMAKE_CXX_FLAGS=-ffunction-sections -fdata-sections -fPIC -m64" "-DCMAKE_INSTALL_PREFIX=/home/joshua/rustc3/build/x86_64-unknown-linux-gnu/llvm" "-DCMAKE_ASM_FLAGS= -ffunction-sections -fdata-sections -fPIC -m64" "-DCMAKE_BUILD_TYPE=Release" CMake Error: The source directory "/home/joshua/rustc3/src/llvm-project/llvm" does not exist.

2021-07-28Auto merge of #86251 - Smittyvb:thir-tree-again, r=oli-obkbors-0/+59
Support -Z unpretty=thir-tree again Currently `-Z unpretty=thir-tree` is broken after some THIR refactorings. This re-implements it, making it easier to debug THIR-related issues. We have to do analyzes before getting the THIR, since trying to create THIR from invalid HIR can ICE. But doing those analyzes requires the THIR to be built and stolen. We work around this by creating a separate query to construct the THIR tree string representation. Closes https://github.com/rust-lang/project-thir-unsafeck/issues/8, fixes #85552.

Add flag to configure `large_assignments` lint The `large_assignments` lints detects moves over specified limit. The limit is configured through `move_size_limit = "N"` attribute placed at the root of a crate. When attribute is absent, the lint is disabled. Make it possible to enable the lint without making any changes to the source code, through a new flag `-Zmove-size-limit=N`. For example, to detect moves exceeding 1023 bytes in a cargo crate, including all dependencies one could use: ``` $ env RUSTFLAGS=-Zmove-size-limit=1024 cargo build -vv ``` Lint tracking issue #83518.
2021-07-27Handle `--no-deps` flag same as `--fix` flag.Nadir Fejzic-3/+6
As proposed in the pull request thread, there is some inconsistency in handling the `--no-deps` flag which requires `--` before it, and `--fix` flag which does not. In this commit the `--no-deps` flag does not need the `--` anymore. However, it can still be used that way: `cargo clipyy -- --no-deps`.
