2021-11-19Rollup merge of #90800 - aplanas:fix_cargo_config, r=Mark-SimulacrumYuki Okushi-9/+14
bootstap: create .cargo/config only if not present In some situations we should want on influence into the .cargo/config when we use vendored source. One example is #90764, when we want to workaround some references to crates forked and living in git, that are missing in the vendor/ directory. This commit will create the .cargo/config file only when the .cargo/ directory needs to be created.
2021-11-18Auto merge of #90382 - alexcrichton:wasm64-libstd, r=joshtriplettbors-1/+1
std: Get the standard library compiling for wasm64 This commit goes through and updates various `#[cfg]` as appropriate to get the wasm64-unknown-unknown target behaving similarly to the wasm32-unknown-unknown target. Most of this is just updating various conditions for `target_arch = "wasm32"` to also account for `target_arch = "wasm64"` where appropriate. This commit also lists `wasm64` as an allow-listed architecture to not have the `restricted_std` feature enabled, enabling experimentation with `-Z build-std` externally. The main goal of this commit is to enable playing around with `wasm64-unknown-unknown` externally via `-Z build-std` in a way that's similar to the `wasm32-unknown-unknown` target. These targets are effectively the same and only differ in their pointer size, but wasm64 is much newer and has much less ecosystem/library support so it'll still take time to get wasm64 fully-fledged.

2021-11-13Change paths for `dist` command to match the components they generateJoshua Nelson-9/+10
Before, you could have the confusing situation where the command to generate a component had no relation to the name of that component (e.g. the `rustc` component was generated with `src/librustc`). This changes the name to make them match up.
2021-11-10Update more rustc/libtest things for wasm64Alex Crichton-1/+1
* Add wasm64 variants for inline assembly along the same lines as wasm32 * Update a few directives in libtest to check for `target_family` instead of `target_arch` * Update some rustc codegen and typechecks specialized for wasm32 to also work for wasm64.

r=Mark-Simulacrum Document clippy on nightly-rustc Adding Clippy's docs to nightly-rustc, based on commit 01cf0bde. This PR only adds `clippy_utils` to the documentation. I've decided to only document one crate for now, as `clippy_lints` etc. contain very specific and undocumented functions which aren't really reusable. I'm guessing that they would mostly clutter up the search results with little benefit. `./x.py --stage 1 doc src/tools/clippy` if working fine now after the help that ```````@jyn514``````` and ```````@ehuss``````` have provided. A big THANK YOU to them!

As suggest in https://github.com/rust-lang/rust/pull/89917#issuecomment-945888574, this PR enables the new symbol mangling scheme for the compiler itself. The standard library is still compiled using the legacy mangling scheme so that the new symbol format does not show up in user code (yet). r? `@Mark-Simulacrum`

I'm working on some LLVM patches in concert with a Rust patch, and it's helping me quite a bit to have this as an option. It doesn't seem that hard, so I figured I'd formalize it in x.py and send it upstream.

r=Mark-Simulacrum Make `llvm.download-ci-llvm="if-available"` work for tier 2 targets with host tools `llvm.download-ci-llvm="if-available"` is used for most profiles configured via `x.py setup`. It allows downloading prebuilt LLVM tarballs from the CI artifacts for a configured list of platforms. Currently this list is restricted to tier 1 targets but it makes sense for all tier 2 targets with host tools.

Allow static linking LLVM with ThinLTO There's no reason not to allow this if the user wants it. It works, at least in a local build on linux host. For our use case, we're happy to spend more time building the compiler if it creates a speedup every time we run it, and we've observed speedups like this with clang.

Assemble the compiler when running `x.py build` Previously, there was no way to actually get binaries in `build/$TARGET/stage1/bin` without building the standard library. This makes it possible to build just the compiler. This can be useful when the standard library isn't actually necessary for trying out your tests (e.g. a bug that can be reproduced with only a `no_core` crate). Closes https://github.com/rust-lang/rust/issues/73519.
2021-10-13Rollup merge of #89757 - jyn514:submodule, r=Mark-SimulacrumMatthias Krüger-1/+1
Use shallow clones for submodules This reduces the amount of git history downloaded for submodules from ~67M to ~11M. For comparison, a shallow clone of rust-lang/rust is 103M and a deep clone is 740M, so this almost halves the amount of history necessary if you made a shallow clone to start, and it's a significant reduction even if not. Closes https://github.com/rust-lang/rust/issues/63978. r? `@Mark-Simulacrum`

Greatly reduce amount of debuginfo compiled for bootstrap itself Rather than compiling rustbuild and all its dependencies with `debuginfo=2`, this compiles dependencies without debuginfo and rustbuild with `debuginfo=1`. On my laptop, this brings compile times down from ~1:20 to ~1:05.

2021-10-11Rollup merge of #89655 - tlyu:find-non-merge-commits, r=jyn514Guillaume Gomez-3/+15
bootstrap: don't use `--merges` to look for commit hashes for downloading artifacts Shallow clones (and possibly worktrees, though I can't seem to reproduce the problem there) can cause `git rev-list --merges` to falsely return no results, even if a merge commit is present. Stop using the `--merges` option when looking for commit hashes that have build artifacts. `--first-parent` and `--author=bors@rust-lang.org` should be sufficient. Also exit with an error if the configuration asks for artifacts to be downloaded and we can't determine an appropriate commit hash to use to download artifacts. Fixes #87890. r? ``@jyn514`` ``@rustbot`` label +A-rustbuild +A-contributor-roadblock

2021-10-02bootstrap: add config option for nix patchingDavid Wood-12/+17
On NixOS systems, bootstrap will patch rustc used in bootstrapping after checking `/etc/os-release` (to confirm the current distribution is NixOS). However, when using Nix on a non-NixOS system, it can be desirable for bootstrap to patch rustc. In this commit, a `patch-binaries-for-nix` option is added to `config.toml`, which allows for user opt-in to bootstrap's Nix patching. Signed-off-by: David Wood <david.wood@huawei.com>
