Tracks association between `self.sess.opts.externs` (aliases in `--extern alias=rlib`) and resolved `CrateNum` Intended to allow Rustdoc match the aliases in `--extern-html-root-url` Force-injected extern crates aren't included, since they're meant for the linker only
In favor of the adhoc `COMPILETEST_FORCE_STAGE0` env var.
…test-allow-stage0`
…explicitly allowed Otherwise, `compiletest` would have to know e.g. how to parse two different target spec, if target spec format was changed between beta `rustc` and in-tree `rustc`.
And move `./x test compiletest --stage=1` to `pr-check-2`, where testing library artifacts already requires building the stage 1 compiler.
Support multiple crate versions in --extern-html-root-url Rustdoc's `--extern-html-root-url` used to use `tcx.crate_name()` to identify crates, but that used crates' internal names from their metadata, instead of names given to them in `--extern`. That was confusing, because both `--extern…` arguments seem related and use similar syntax. Crucially, this didn't work correctly with Cargo's package aliases or multiple versions of crates. `sess.opts.externs` lacks `CrateNum`, and `Resolver.extern_prelude` gets destroyed before `rustdoc` has a chance to see it, so I've had to save this mapping in `CStore`. Just in case, I've kept the previous mapping by crate name as a fallback for crates that weren't matched by their extern name. Fixes rust-lang#76296
…s, r=lolbinarycat [rustdoc] Display total time and compilation time of merged doctests Fixes rust-lang#144270. Does it look good to you `@kpreid?` <img width="908" height="263" alt="image" src="https://github.com/user-attachments/assets/cd5d082d-c4e0-42ed-91dd-bd263b413dcd" />
…trs, r=WaffleLapkin clean up codegen fn attrs This honestly had become a mess over time and needed some love. No behavior should've changed, and I effectively just moved code around. Though, I can't promise there weren't any bugs in the original code with how randomly it was organised..... r? `@WaffleLapkin`
…bzol Reject running `compiletest` self-tests against stage 0 rustc unless explicitly allowed Currently, in `pr-check-1`, we run `python3 ../x.py test --stage 0 src/tools/compiletest`, which is `compiletest` self-tests against stage 0 rustc. This makes it very annoying for PRs wanting to change target spec JSON format, which `compiletest` depends on for target information, as otherwise `compiletest` would have to know how to handle 2 different target spec JSON formats and know when to pick which. Instead of doing that, we change `compiletest` self-tests to reject running against stage 0 `rustc` *unless* explicitly allowed with `build.compiletest-allow-stage0=true`. `build.compiletest-allow-stage0` is a proper bootstrap config option in favor of the ad-hoc `COMPILETEST_FORCE_STAGE0` env var. This means that: - `./x test src/tools/compiletest --stage=0` is not allowed, unless `build.compiletest-allow-stage0=true` is set. In this scenario, `compiletest` self-tests should be expected to fail unless the stage 0 `rustc` as provided is like codegen_cranelift where it's *actually* built from in-tree `rustc` sources. - In CI, we change `./x test src/tools/compiletest --stage=0` to `./x test src/tools/compiletest --stage=1`, and move it to `pr-check-2`. Yes, this involves building the stage 1 compiler, but `pr-check-2` already has to build stage 1 compiler to test stage 1 library crates. - Crucially, this means that **`compiletest` is only intended to support one target spec JSON format**, namely the one corresponding to the in-tree `rustc`. - This should preserve the `compiletest-use-stage0-libtest` UX optimization where changing `compiler/` tree should still not require rebuilding `compiletest` as long as `build.compiletest-use-stage0-libtest=true`, as that should remain orthogonal. This is completely unlike my previous attempt at rust-lang#144563 that tries to do a way more invasive change which would cause the rebuild problem. Best reviewed commit-by-commit. --- r? `@Kobzol`
