@jyn514 yes, it does and so does rustc --version --verbose |
|
I think since it could change your build in a subtle way, we should note this in the changelog. r=me with that. |
This fixes ongoing issues where x.py will detect the wrong host triple between MSVC and GNU. - Add line to changelog

…ulacrum Infer the default host target from the host toolchain if possible - `beta-x86_64-unknown-linux-gnu` has beta stripped - `rustc2` is ignored This fixes ongoing issues where x.py will detect the wrong host triple between MSVC and GNU. I don't think this will break anyone's workflow - I'd be very surprised if you a) had no `[build]` section in `config.toml`, b) had rustc installed, and c) expected the default target to be something other than the default target used by `rustc`. But I could be wrong - I'm happy to hear user stories :) Fixes rust-lang#78150. r? `@Mark-Simulacrum` cc `@Lokathor`

Fix rustup support in default_build_triple for python3 bootstrap completely ignores all errors when detecting a rustup version, so this wasn't noticed before. Fixes the following error: ``` rustup not detected: a bytes-like object is required, not 'str' falling back to auto-detect ``` This also takes the opportunity to only call rustup and other external commands only once during startup. Follow-up to rust-lang#78513.
