2017-09-04Auto merge of #43067 - pornel:libdeps, r=nrcbors-7/+52
Compact display of static lib dependencies Fixes #33173 Instead of displaying one dependency per line, I've changed the format to display them all in one line. As a bonus they're in format of linker flags (`-lfoo`), so the output can be copy&pasted if one is actually going to link as suggested.

2017-09-03Auto merge of #44191 - arielb1:on-unimplemented-label, r=nikomatsakisbors-275/+652
More general `on_unimplemented`, with uses in `Try` Allow `on_unimplemented` directives to specify both the label and the primary message of the trait error, and allow them to be controlled by flags - currently only to be desugaring-sensitive. e.g. ```Rust #[rustc_on_unimplemented( on(all(direct, from_desugaring="?"), message="the `?` operator can only be used in a \ function that returns `Result` \ (or another type that implements `{Try}`)", label="cannot use the `?` operator in a function that returns `{Self}`"), )] ``` r? @nikomatsakis

2017-09-03Auto merge of #44252 - eddyb:what-is-dead-may-never-die, r=nikomatsakisbors-35/+94
Better StorageLive / StorageDead placement for constants. Fixes problems in miri (see https://github.com/solson/miri/pull/324#issuecomment-326555552) caused by the new scope rules in #43932. What I've tried to do here is always have a `StorageLive` but no `StorageDead` for `'static` slots. It might not work perfectly in all cases, but it should unblock miri. r? @nikomatsakis cc @oli-obk
2017-09-03Auto merge of #44195 - alexcrichton:remove-used-unsafe, r=nikomatsakisbors-74/+66
rustc: Remove the `used_unsafe` field on TyCtxt Now that lint levels are available for the entire compilation, this can be an entirely local lint in `effect.rs` cc #44137
2017-09-03Auto merge of #44176 - nrc:update-rls, r=alexcrichtonbors-7/+13
Update rls And expose the `CFG_VERSION` env var to tools so they can determine the version of Rust. This gets the RLS back on master and so completes the PR dance for the generators PR. r? @alexcrichton

2017-09-02Auto merge of #44066 - cuviper:powerpc64-extern-abi, r=alexcrichtonbors-44/+151
powerpc64: improve extern struct ABI These fixes all have to do with the 64-bit PowerPC ELF ABI for big-endian targets. The ELF v2 ABI for powerpc64le already worked well. - Return after marking return aggregates indirect. Fixes #42757. - Pass one-member float aggregates as direct argument values. - Aggregate arguments less than 64-bit must be written in the least- significant bits of the parameter space. - Larger aggregates are instead padded at the tail. (i.e. filling MSBs, padding the remaining LSBs.) New tests were also added for the single-float aggregate, and a 3-byte aggregate to check that it's filled into LSBs. Overall, at least these formerly-failing tests now pass on powerpc64: - run-make/extern-fn-struct-passing-abi - run-make/extern-fn-with-packed-struct - run-pass/extern-pass-TwoU16s.rs - run-pass/extern-pass-TwoU8s.rs - run-pass/struct-return.rs
2017-09-02Auto merge of #43886 - oli-obk:clippy, r=nrcbors-1/+46
Add clippy as a submodule ~~This builds clippy as part of `./x.py build` (locally and in CI).~~ This allows building clippy with `./x.py build src/tools/clippy` ~~Needs https://github.com/nrc/dev-tools-team/issues/18#issuecomment-322456461 to be resolved before it can be merged.~~ Contributers can simply open a PR to clippy and point the submodule at the `pull/$pr_number/head` branch. This does **not** build clippy or test the clippy test suite at all as per https://github.com/nrc/dev-tools-team/issues/18#issuecomment-321411418 r? @nrc cc @Manishearth @llogiq @mcarton @alexcrichton

2017-09-02Auto merge of #44104 - llogiq:lowercase-lints, r=nikomatsakisbors-3/+58
add a lowercase suggestion to unknown_lints I recently wrote some tests for a clippy lint, copied the (uppercase) lint name into my test file and forgot to toggle the case. This PR adds a suggestion that would have saved me 10 minutes of debugging, so it's likely a net win 🙂 . Also it adds a UI test for the `unknown_lints` lint.

2017-09-01x86: return single-float aggregates in a float registerJosh Stone-6/+35
Following Clang's lead, and anecdotal evidence from the `float_one` part of `run-make/extern-fn-struct-passing-abi`, use a floating point register to return single-float aggregates, except on MSVC targets.
