2021-07-28Rollup merge of #87500 - Smittyvb:min-max-docs, r=kennytmYuki Okushi-12/+15
Document math behind MIN/MAX consts on integers Currently the documentation for `[integer]::{MIN, MAX}` doesn't explain where the constants come from. This documents how the values of those constants are related to powers of 2.

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.

2021-07-28Rollup merge of #87330 - inquisitivecrystal:extend-reserve, r=JohnTitorYuki Okushi-9/+1
Use hashbrown's `extend_reserve()` in `HashMap` When we added `extend_reserve()` to our implementation of `Extend` for `HashMap`, hashbrown didn't have a version we could use. Now that hashbrown has added it, we should use its version instead of implementing it ourself.

Stabilize `const_fn_transmute`, `const_fn_union` This PR stabilizes the `const_fn_transmute` and `const_fn_union` features. It _does not_ stabilize any methods (obviously aside from `transmute`) that are blocked on only these features. Closes #53605. Closes #51909.

2021-07-27Rollup merge of #86450 - tmiasko:move-size-limit, r=pnkfelixYuki Okushi-6/+64
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.
2021-07-27Auto merge of #87431 - the8472:array-iter-fold, r=kennytmbors-0/+27
implement fold() on array::IntoIter to improve flatten().collect() perf With #87168 flattening `array::IntoIter`s is now `TrustedLen`, the `FromIterator` implementation for `Vec` has a specialization for `TrustedLen` iterators which uses internal iteration. This implements one of the main internal iteration methods on `array::Into` to optimize the combination of those two features. This should address the main issue in #87411 ``` # old test vec::bench_flat_map_collect ... bench: 2,244,024 ns/iter (+/- 18,903) # new test vec::bench_flat_map_collect ... bench: 172,863 ns/iter (+/- 2,141) ```
