2018-07-30Auto merge of #52805 - ljedrz:format_str_literal, r=petrochenkovbors-17/+17
Don't format!() string literals Prefer `to_string()` to `format!()` take 2, this time targetting string literals. In some cases (`&format!("...")` -> `"..."`) also removes allocations. Occurences of `format!("")` are changed to `String::new()`.
2018-07-29Auto merge of #52738 - ljedrz:push_to_extend, r=eddybbors-18/+16
Replace push loops with extend() where possible Or set the vector capacity where I couldn't do it. According to my [simple benchmark](https://gist.github.com/ljedrz/568e97621b749849684c1da71c27dceb) `extend`ing a vector can be over **10 times** faster than `push`ing to it in a loop: 10 elements (6.1 times faster): ``` test bench_extension ... bench: 75 ns/iter (+/- 23) test bench_push_loop ... bench: 458 ns/iter (+/- 142) ``` 100 elements (11.12 times faster): ``` test bench_extension ... bench: 87 ns/iter (+/- 26) test bench_push_loop ... bench: 968 ns/iter (+/- 3,528) ``` 1000 elements (11.04 times faster): ``` test bench_extension ... bench: 311 ns/iter (+/- 9) test bench_push_loop ... bench: 3,436 ns/iter (+/- 233) ``` Seems like a good idea to use `extend` as much as possible.

2018-07-26Auto merge of #52488 - nikomatsakis:nll-issue-48071-universe-and-sub, r=pnkfelixbors-10/+10
introduce universes to NLL type check This branch aims to fix #48071 and also advance chalk integration a bit at the same time. It re-implements the subtyping/type-equating check so that NLL doesn't "piggy back" on the subtyping code of the old type checker. This new code uses the "universe-based" approach to handling higher-ranked lifetimes, which sidesteps some of the limitations of the current "leak-based" scheme. This avoids the ICE in #48071. At the same time, I aim for this to potentially be a kind of optimization. This NLL code is (currently) not cached, but it also generates constraints without doing as much instantiation, substitution, and folding. Right now, though, it still piggy backs on the `relate_tys` trait, which is a bit unfortunate -- it means we are doing more hashing and things than we have to. I want to measure the see the perf. Refactoring that trait is something I'd prefer to leave for follow-up work. r? @pnkfelix -- but I want to measure perf etc first
2018-07-26Rollup merge of #52690 - paoloteti:rclass-dsp, r=alexcrichtonMark Rousskov-0/+2
ARM: expose `rclass` and `dsp` target features - `dsp`: the subtarget supports the DSP (saturating arith. and such) instructions - `rclass`: target is a Cortex-R Both features are useful to support ARM MCUs on `coresimd`. Note: Cortex-R52 is the first Armv8-R with `neon` support. r? @alexcrichton cc @japaric
2018-07-26Rollup merge of #52654 - alecmocatta:master, r=alexcrichtonMark Rousskov-17/+19
Format linker args in a way that works for gcc and ld Pass multiple linker arguments rather than concatenate with commas (fixes #52634). `-l library` -> `-llibrary` to work with apple's ld. To build with apple's ld I'm currently also passing `-C link-args="-arch x86_64 -macosx_version_min 10.13.0"`. I'll try and understand the latter flag better before PRing that. This PR currently works for me. Hopefully CI will pick up any grievous ramifications in other toolchains? Thanks to @alexcrichton for the pointer to the relevant code!

2018-07-24Rollup merge of #52391 - Amanieu:volatile_unaligned, r=alexcrichtonMark Rousskov-3/+23
Add unaligned volatile intrinsics Surprisingly enough, it turns out that unaligned volatile loads are actually useful for certain (very niche) types of lock-free code. I included unaligned volatile stores for completeness, but I currently do not know of any use cases for them. These are only exposed as intrinsics for now. If they turn out to be useful in practice, we can work towards stabilizing them. r? @alexcrichton

2018-07-18rustc: Stabilize #[wasm_import_module] as #[link(...)]Alex Crichton-32/+54
This commit stabilizes the `#[wasm_import_module]` attribute as `#[link(wasm_import_module = "...")]`. Tracked by #52090 this new directive in the `#[link]` attribute is used to configured the module name that the imports are listed with. The WebAssembly specification indicates two utf-8 names are associated with all imported items, one for the module the item comes from and one for the item itself. The item itself is configurable in Rust via its identifier or `#[link_name = "..."]`, but the module name was previously not configurable and defaulted to `"env"`. This commit ensures that this is also configurable. Closes #52090
2018-07-16rustc: Use link_section, not wasm_custom_sectionAlex Crichton-79/+47
This commit transitions definitions of custom sections on the wasm target from the unstable `#[wasm_custom_section]` attribute to the already-stable-for-other-targets `#[link_section]` attribute. Mostly the same restrictions apply as before, except that this now applies only to statics. Closes #51088
