Since compiling the bootstrap command doesn't require any submodules, we can skip updating submodules when a --help command is passed in. On my machine, this saves 1 minute if the submodules are already downloaded, and 10 minutes if run on a clean repo. This commit also adds a message before compiling/downloading anything when a --help command is passed in, to tell the user WHY --help takes so long to complete. It also points the user to the bootstrap README.md for faster help. Finally, this fixes one warning message that still referenced using make instead of x.py, even though x.py is now the standard way of building rust.
The build might otherwise break due to mixing MinGW object files from rust-std and the local MinGW which might be newer/older than the version used to build rust-std. Fixes rust-lang#48272
It was an existing solution to tell the user why a --help command takes a long time to process. However, it would only print if the stage0 rust compiler needed to be downloaded, it came after update_submodules (which took a long time), and it was immediately followed by download messages and loading bars, meaning users could easily gloss over the message. This commit also moves the help message out of main(), and instead puts it at the top of bootstrap(). main() is intended to be minimal, only handling error messages.
This allows to parallel-install several versions of rust system-wide Fixes rust-lang#48263 Signed-off-by: Marc-Antoine Perennou <Marc-Antoine@Perennou.com>
Currently, we are producing headers for markdown files, which is generally not what we want. As such, passing this flag causes them to render normally.
This commit imports the `stdsimd` crate into the standard library, creating an `arch` and `simd` module inside of both libcore and libstd. Both of these modules are **unstable** and will continue to be so until RFC 2335 is stabilized. As a brief recap, the modules are organized as so: * `arch` contains all current architectures with intrinsics, for example `std::arch::x86`, `std::arch::x86_64`, `std::arch::arm`, etc. These modules contain all of the intrinsics defined for the platform, like `_mm_set1_epi8`. * In the standard library, the `arch` module also exports a `is_target_feature_detected` macro which performs runtime detection to determine whether a target feature is available at runtime. * The `simd` module contains experimental versions of strongly-typed lane-aware SIMD primitives, to be fully fleshed out in a future RFC. The main purpose of this commit is to start pulling in all these intrinsics and such into the standard library on nightly and allow testing and such. This'll help allow users to easily kick the tires and see if intrinsics work as well as allow us to test out all the infrastructure for moving the intrinsics into the standard library.
…GuillaumeGomez add readme for librustdoc In the same vein as the other compiler-library readmes, here's one for rustdoc! It's mainly a "how does rustdoc even" blog-post-style writeup, but i wanted to have something in-repo so people could get a sense of what bits did what.
Disable NEON on musl ARMv7 `armv7-unknown-linux-musleabihf` target diverged a bit from `armv7-unknown-linux-gnueabihf` target. This PR re-syncs them. Fix rust-lang#47765.

🤔 Same error, meaning #48664 is not the cause. Remaining PRs involved in both tests:
I'm going to take out #48642 this time... |
Don't produce TOCs for doc markdown files Currently, we are producing headers for markdown files, which is generally not what we want. As such, passing this flag causes them to render normally. https://doc.rust-lang.org/nightly/book/ is an example page currently where this is done incorrectly.
