2019-10-31Rollup merge of #65959 - vext01:immediate-docstring, r=davidtwcoMazdak Farrokhzad-1/+1
Fix an incorrect docstring for Immediate in librustc_mir/interpret. I suspect `Immediate` was once called `Value`?

2019-10-31Rollup merge of #65850 - mikeyhew:patch-1, r=nikomatsakisMazdak Farrokhzad-5/+7
Update comments re type parameter hack in object safety To check if a method's receiver type is object safe, we create a new receiver type by substituting in a bogus type parameter (let's call it `U`) for `Self`, and checking that the unmodified receiver type implements `DispatchFromDyn<receiver type with Self = U>`. It would be better to use `dyn Trait` directly, and the only reason we don't is because it triggers another check that `Trait` is object safe, resulting in a query cycle. Once the feature `object_safe_for_dispatch` (tracking issue https://github.com/rust-lang/rust/issues/43561) is stabilized, this will no longer be the case, and we'll be able to use `dyn Trait` as the unsized `Self` type. I've updated the comments in object_safety.rs accordingly. cc @Centril @nikomatsakis @bovinebuddha

2019-10-31Rollup merge of #65274 - pietroalbini:ci-upload-toolstate, r=alexcrichtonMazdak Farrokhzad-35/+73
Upload toolstates.json to rust-lang-ci2 This PR does two things: * Following up with https://github.com/rust-lang/rust/pull/65202, it migrates deploying artifacts to CI in a script. Both uploading release artifacts and CPU stats were merged into the same script, designing it to be easily extended. * Uploads the toolstate JSON to `rust-lang-ci2` along with the release artifacts, both for Linux and Windows. This is needed because @RalfJung wants to stop shipping MIRI when its tests are failing, and the toolstate repo doesn't have entries for each commit. Having the toolstate data (just for that specific commit) on `rust-lang-ci2` will simplify the code a lot. r? @alexcrichton cc @RalfJung
2019-10-30ci: move toolstates.json to /tmp/toolstate/ and docker mount itPietro Albini-6/+13
Before this commit toolstates.json was stored in /tmp and it wasn't mounted outside the build container. That caused uploading the file in the upload-artifacts task to fail, as the file was missing on the host. Mounting /tmp/toolstates.json alone is not the best approach: if the file is missing when the container is started the Docker engine will create a *directory* named /tmp/toolstates.json. The Docker issue could be solved by pre-creating an empty file named /tmp/toolstates.json, but doing that could cause problems if bootstrap fails to generate the file and the toolstate scripts receive an empty JSON. The approach I took in this commit is to instead mount a /tmp/toolstate directory inside Docker, and create the toolstates.json file in it. That also required a small bootstrap change to ensure the directory is created if it's missing.

2019-10-29Rollup merge of #65920 - smaeul:patch/workspace-hack, r=alexcrichtonTyler Mandry-0/+6
Use rustc-workspace-hack for rustbook As rustbook now depends transitively on openssl, it needs access to the rustc-workspace-hack/all-static feature to pick up openssl-sys/vendored. This fixes the rust build with `all-static = true` on systems where openssl is not installed (e.g. when cross-compiling).

r=alexcrichton ci: refactor pr tools job skipping We have a job in our CI (PR's x86_64-gnu-tools) that's supposed to run only when a submodule is changed in the PR, and it works by having a task at the start of the build that skips all the following tasks if the condition isn't met. Before this commit that task was gated with template parameters, which is a unique feature of Azure Pipelines. To make our CI more generic this commit switches the gate to use a simple environment variable plus a condition, which should be supported on more CI providers. This PR also extracts the skipping logic into a script. r? @alexcrichton

2019-10-29Auto merge of #65927 - eddyb:eval-always-considered-harmful, r=michaelwoeristerbors-2/+0
Don't use eval_always for miri queries used from codegen. This should fix the [massive incremental perf regression](https://perf.rust-lang.org/compare.html?start=95f437b3cfb2fec966d7eaf69d7c2e36f9c274d1&end=9285d401a6070094747465962bc49969b93e14c5&stat=instructions:u) introduced in #65664. It seems that `eval_always` was mistakenly(?) added to `const_field` and then it ended up on `const_caller_location` (which is used much more often than `const_field` is). r? @michaelwoerister cc @oli-obk @nnethercote

2019-10-29Auto merge of #65435 - michaelwoerister:fix-issue-64153, r=alexcrichtonbors-21/+68
Fix #64153 This PR changes how the compiler detects if an object file from an upstream crate is a Rust object file or not. Instead of checking if the name starts with the crate name and ends with `.o` (which is not always the case, as described in #64153), it now just checks if the filename ends with `.rcgu.o`. This fixes #64153. However, ideally we'd clean up the code around filename generation some more. Then this check could be made more robust. r? @alexcrichton

2019-10-29Rollup merge of #65809 - roblabla:eficall-abi, r=nagisaMazdak Farrokhzad-82/+203
Add new EFIAPI ABI Fixes #54527 Adds a new ABI, "efiapi", which reflects the calling convention as specified by [the current spec UEFI spec](https://uefi.org/sites/default/files/resources/UEFI%20Spec%202_7_A%20Sept%206.pdf#G6.999903). When compiling for x86_64, we should select the `win64` ABI, while on all other architectures (Itanium, x86, ARM and ARM64 and RISC-V), we should select the `C` ABI. Currently, this is done by just turning it into the C ABI everywhere except on x86_64, where it's turned into the win64 ABI. Should we prevent this ABI from being used on unsupported architectures, and if so, how would this be done?
