This will make `-Zbuild-std` automatically build the right crates, notably not building `std` by default, which will both be useful for users and also fix the build for https://does-it-build.noratrieb.dev.

…json, r=fmease Fix doctest output json Fixes rust-lang#144798. Hopefully it will work with the new changes in `libtest` without needing to do both at once. This PR moves the `rustdoc` merged doctest extra information directly into `libtest` to ensure they share the same rendering to prevent the bug uncovered in rust-lang#144798. cc `@lolbinary` (as you reviewed the first PR) And since we're making changes to `libtest`: r? `@Amanieu`

Make #[link="dl"] an FCW rather than an error Fixes rust-lang#147254 I forgot to implement the T-lang decision in rust-lang#143193 (comment), this implements that decision r? ``@jdonszelmann`` Can be reviewed commit-by-commit This needs a beta backport

…eyouxu update autodiff testcases unblock EnzymeAD/Enzyme#2430 (again). Just as I landed a fix for the last test, this one broke. The test should now be fine if the name mangling hash changes again. Also removed an outdated fixme that's not needed since moving autodiff to an intrinsic. The test currently just checks that it compiles, I'll add more precise checks once we actually run this in CI. r? compiler

Fill out AVR target metadata This will make `-Zbuild-std` automatically build the right crates, notably not building `std` by default, which will both be useful for users and also fix the build for https://does-it-build.noratrieb.dev, which currently tries to build std: http://localhost:3000/build?nightly=2025-07-12&target=avr-none&mode=std. cc `@Patryk27` but I don't think this necessarily needs your approval

What is this?

This is an experimental post-merge analysis report that shows differences in test outcomes between the merged PR and its parent PR.

Comparing e2c96cc (parent) -> bcbbdcb (this PR)

Test differences

Show 10 test diffs

Stage 1

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
