2025-06-13Rollup merge of #135927 - azhogin:azhogin/retpoline, r=davidtwcoMatthias Krüger-2/+3
retpoline and retpoline-external-thunk flags (target modifiers) to enable retpoline-related target features `-Zretpoline` and `-Zretpoline-external-thunk` flags are target modifiers (tracked to be equal in linked crates). * Enables target features for `-Zretpoline-external-thunk`: `+retpoline-external-thunk`, `+retpoline-indirect-branches`, `+retpoline-indirect-calls`. * Enables target features for `-Zretpoline`: `+retpoline-indirect-branches`, `+retpoline-indirect-calls`. It corresponds to clang -mretpoline & -mretpoline-external-thunk flags. Also this PR forbids to specify those target features manually (warning). Issue: rust-lang/rust#116852

2025-06-13Rollup merge of #142379 - Stypox:bootstrap-tool-config, r=KobzolMatthias Krüger-2/+36
Add bootstrap option to compile a tool with features Add an option to specify which features to build a tool with, e.g. it will be useful to build Miri with tracing enabled: ```toml tool-config.miri.features = ["tracing"] ``` See [this Zulip thread](https://rust-lang.zulipchat.com/#narrow/channel/326414-t-infra.2Fbootstrap/topic/Passing.20--features.20to.20Miri.20build.20using.20.2E.2Fx.2Epy/with/523564773) for the options considered. If the final decision will be different than what I wrote now, I will update the code as needed. The reason why the option is `tool-config.miri.features` instead of something like `tool-features.miri` is to possibly allow adding more tool-specific configurations in the future. I didn't do any validation of the keys of the `tool-config` hashmap, since I saw that no validation is done on the `tools` hashset either. I don't like much the fact that features can be chosen by various places of the codebase: `Step`s can have some fixed `extra_features`, `prepare_tool_cargo` will add features depending on some bootstrapping options, and the newly added option can also contribute features to tools. However I think it is out of scope of this PR to try to refactor all of that (if it even is refactorable), so I left a comment in the codebase explaining all of the sources of features I could find.

Tracking the old name of renamed unstable library features This PR resolves the first problem of rust-lang/rust#141617 : tracking renamed unstable features. The first commit is to add a ui test, and the second one tracks the changes.

miri: add flag to suppress float non-determinism We have flags controlling most non-determinism, so this seems generally useful for debugging. It is also needed to work around https://github.com/rust-lang/portable-simd/issues/463 in miri-test-libstd. I made this a rustc PR so that it propagates faster to unbreak miri-test-libstd. r? `@oli-obk`

2025-06-12Introduce `-Zmacro-stats`.Nicholas Nethercote-0/+24
It collects data about macro expansions and prints them in a table after expansion finishes. It's very useful for detecting macro bloat, especially for proc macros. Details: - It measures code snippets by pretty-printing them and then measuring lines and bytes. This required a bunch of additional pretty-printing plumbing, in `rustc_ast_pretty` and `rustc_expand`. - The measurement is done in `MacroExpander::expand_invoc`. - The measurements are stored in `ExtCtxt::macro_stats`.
