This "cleanup" function is more than a decade old, and I can't find any evidence of modern-day bootstrap being able to pass any of these flags to `--host-rustcflags` or `--target-rustcflags`.
There are probably plenty of tests that will check this incidentally, but it's convenient to have a dedicated self-test.
In particular, this eliminates the cryptic `of: &TestPaths` parameters.
This method no longer returns a `TestPaths`, so the old name is no longer appropriate.

split definition and use site hidden tys Tracking this implicitly is kinda messy and easy to get wrong. r? `@BoxyUwU`
compiletest: Remove `cleanup_debug_info_options` This "cleanup" function is more than a decade old, and I can't find any evidence of modern-day bootstrap being able to pass any of these flags to `--host-rustcflags` or `--target-rustcflags`. I thought about replacing the cleanup with an assertion, but I think it's better to delete it entirely for now, and re-add checks later if they're motivated by actual problems in practice. In addition to deleting some old and confusing code, this also lets us remove three instances of duplicating `TestCx`, which is the biggest win. r? jieyouxu
compiletest: Don't modify `testpaths` when creating aux contexts Modifying `TestCx::testpaths` makes it vastly harder to reason about how compiletest is using test paths, and can be avoided without much trouble by simply passing explicit source-file paths into a small number of auxiliary-aware methods. --- This PR was originally based on a much larger change that split `TestPaths` into multiple structs and multiple `TestCx` fields (as seen in early revisions of rust-lang#148160), but after further cleanups it turned out that very few tweaks were actually needed to avoid changes to `testpaths`. r? jieyouxu
…fleLapkin rustc_codegen: fix musttail returns for cast/indirect ABIs Fixes rust-lang#148239 rust-lang#144986 Explicit tail calls trigger `bug!` for any callee whose ABI returns via `PassMode::Cast`, and we forgot to to forward the hidden `sret` out-pointer when the ABI requested an indirect return. The former causes ICE, the latter produced malformed IR (wrong codegen) if the return value is large enough to need `sret`. Updated the musttail helper to accept cast-mode returns, made it so that we pass the return pointer through the tail-call path. Added two UI tests to demonstrate each case. This is my first time contributing, please do check if I did it right. r? theemathas

Do not emit solver errors that contain error types
any follow-up errors are going to either be duplicates or often disappear if the error itself is fixed.
in this PR it mostly silences dyn-compat errors as all the other errors are already deduplicated outside of the test suite. The dyn compat errors are independent errors and I think if the dyn compatiblity depended on an error type it would not actually show, so this is PR is actually silencing independent errors, too.
I am opening this PR because I am seeing lots of `{type error}: const Trait` errors when adding more const checking. So instead of targetting just those specific errors, I wanted to try out fully avoiding such errors near the trait solver.

…r=Noratrieb docs: makes a note about possible building `rustc 1.91.0 + host tools` for win7 I have make notes in docs that there is possible to build host tools for target `x86_64-win7-windows-msvc`. <img width="668" height="331" alt="image" src="https://github.com/user-attachments/assets/0335bc72-963c-4bfd-9910-61963dbf7dd7" /> r? ````@roblabla```` ````@rustbot```` label A-docs O-windows-7 P.S. prebuilt binaries can be found [here](https://github.com/Fenex/rust-win7/releases).
…ouxu Use --print host-tuple to get the host `--print host-tuple` has been available since 1.84 so there's no longer a need to parse the output of `-vV`. Especially since this script is shipped with the toolchain.
