2022-09-25	Don't set RUSTC in the bootstrap build script	Joshua Nelson	-36/+0
	We no longer use this for anything since https://github.com/rust-lang/rust/pull/98483/files#diff-7eddc76f1be9eca2599a9ae58c65ffe247fbdff9b02ef687439894cab9afe749L781. Remove it, so that we spuriously rebuild bootstrap fewer times on Windows (where PATH changes often).
2022-03-23	Fix `cargo run` on Windows	Joshua Nelson	-2/+17
	Fixes the following error: ``` error: failed to run custom build command for `bootstrap v0.0.0 (C:\Users\Walther\git\rust\src\bootstrap)` Caused by: process didn't exit successfully: `C:\Users\Walther\git\rust\target\debug\build\bootstrap-7757a4777dec0f86\build-script-build` (exit code: 101) --- stdout cargo:rerun-if-changed=build.rs cargo:rerun-if-env-changed=RUSTC cargo:rustc-env=BUILD_TRIPLE=x86_64-pc-windows-msvc cargo:rerun-if-env-changed=PATH --- stderr thread 'main' panicked at 'assertion failed: rustc.is_absolute()', src\bootstrap\build.rs:22:5 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace warning: build failed, waiting for other jobs to finish... error: build failed ``` The problem was that the `dir.join` check only works with rustc.exe, not rustc. Thanks Walther for the help testing the fix!
2022-02-26	avoid rebuilding bootstrap when PATH changes	Ralf Jung	-1/+1

2022-02-06	Rerun bootstrap's build script when RUSTC changes	Joshua Nelson	-0/+2
	Previously, rustbuild would give strange errors if you tried to reuse the same build directory under two names: ``` $ mkdir tmp && cd tmp $ ../x.py check Building rustbuild Finished dev [unoptimized] target(s) in 35.27s Checking stage0 std artifacts (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu) ^C $ cd .. $ mv tmp/build build $ ./x.py check Building rustbuild Compiling bootstrap v0.0.0 (/home/jnelson/rust-lang/rust/src/bootstrap) Finished dev [unoptimized] target(s) in 11.18s failed to execute command: "/home/jnelson/rust-lang/rust/tmp/build/x86_64-unknown-linux-gnu/stage0/bin/rustc" "--target" "x86_64-unknown-linux-gnu" "--print" "target-libdir" error: No such file or directory (os error 2) ``` This fixes the error. Reusing the same build directory is useful if you want to test path-things in bootstrap itself, without having to recompile it each time. For good measure, this also reruns the build script when PATH changes.
2020-09-20	Discover Rust toolchain without Python	Mark Rousskov	-1/+24

2020-09-20	Set BUILD_TRIPLE via build script	Mark Rousskov	-0/+3
	This moves build triple discovery for rustbuild from bootstrap.py into a build script, meaning it will "just work" if building rustbuild via Cargo rather than Python.
