2020-04-07Rollup merge of #70857 - faern:use-assoc-int-float-consts, r=dtolnayDylan DPC-68/+52
Don't import integer and float modules, use assoc consts 2 Follow up to #70777. I missed quite a lot of places. Partially because I wanted to keep the size of the last PR down, and partially because my regexes were not good enough :) r? @dtolnay
2020-04-07Rollup merge of #70854 - faern:use-assoc-int-submodules, r=dtolnayDylan DPC-0/+0
Use assoc int submodules Bumping some submodules to the commits their masters currently point at. The main point of this is to get the associated integer/float constant documentation updates that were recently merged to them: * https://github.com/rust-lang/nomicon/pull/207 * https://github.com/rust-lang/rust-by-example/pull/1327 * https://github.com/rust-lang/stdarch/pull/848 But for some, a few more changes slipped by that happened to be in the master branch of these submodules. r? @dtolnay
2020-04-07Rollup merge of #70846 - tmiasko:compiler-builtins-codegen-units, r=alexcrichtonDylan DPC-1/+48
Keep codegen units unmerged when building compiler builtins Make it possible to control how mono items are partitioned into code generation units, when compiling the compiler builtins, by retaining the original partitioning. Helps with #48625, #61063, #67960, #70489. r? @alexcrichton
2020-04-07Rollup merge of #70762 - RalfJung:miri-leak-check, r=oli-obkDylan DPC-76/+116
Miri leak check: memory reachable through globals is not leaked Also make Miri memory dump prettier by sharing more code with MIR dumping, and fix a bug where the Miri memory dump would print some allocations twice. r? @oli-obk Miri PR: https://github.com/rust-lang/miri/pull/1301
2020-04-07Rollup merge of #70201 - cuviper:clone_into, r=dtolnayDylan DPC-8/+36
Small tweaks in ToOwned::clone_into - `<[T]>::clone_into` is slightly more optimized. - `CStr::clone_into` is new, letting it reuse its allocation. - `OsStr::clone_into` now forwards to the underlying slice/`Vec`.
2020-04-07Auto merge of #70837 - nnethercote:speed-up-find_library_crate, r=petrochenkovbors-21/+45
Speed up path searching with `find_library_crate`. By doing prefix and suffix checking on a `String` copy of each relevant `PathBuf`, rather than the `PathBuf` itself.
2020-04-07Auto merge of #70164 - eddyb:walk-generic-arg, r=nikomatsakisbors-603/+618
ty/walk: iterate `GenericArg`s instead of `Ty`s. Before this PR, `Ty::walk` only iterated over `Ty`s, but that's becoming an increasing problem with `const` generics, as `ty::Const`s in `Substs` are missed by it. By working with `GenericArg` instead, we can handle both `Ty`s and `ty::Const`s, but also `ty::Region`s, which used to require ad-hoc mechanisms such as `push_regions`. I've also removed `TraitRef::input_types`, as it's both long obsolete, and easy to misuse.
2020-04-06Forward OsStr::clone_into to the inner VecJosh Stone-2/+13
Despite OS differences, they're all just `Vec<u8>` inside, so we can just forward `clone_into` calls to that optimized implementation.
2020-04-06Implement ToOwned::clone_into for CStrJosh Stone-0/+17
It can try to keep its allocation by converting the inner `Box` to `Vec`, using `clone_into` on the bytes, then convert back to `Box`.

2020-04-06Use split_at in slice's ToOwned::clone_intoJosh Stone-6/+6
It appears to codegen slightly more efficiently with `split_at` taking two slices at once, rather than slicing across different calls.
