Introduce and use specialized `//@ ignore-auxiliary` for test support files instead of using `//@ ignore-test` ### Summary Add a semantically meaningful directive for ignoring test *auxiliary* files. This is for auxiliary files that *participate* in actual tests but should not be built by `compiletest` (i.e. these files are involved through `mod xxx;` or `include!()` or `#[path = "xxx"]`, etc.). ### Motivation A specialized directive like `//@ ignore-auxiliary` makes it way easier to audit disabled tests via `//@ ignore-test`. - These support files cannot use the canonical `auxiliary/` dir because they participate in module resolution or are included, or their relative paths can be important for test intention otherwise. Follow-up to: - rust-lang#139705 - rust-lang#139783 - rust-lang#139740 See also discussions in: - [#t-compiler > Directive name for non-test aux files?](https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/Directive.20name.20for.20non-test.20aux.20files.3F/with/512773817) - [#t-compiler > Handling disabled &rust-lang#96;//@ ignore-test&rust-lang#96; tests](https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/Handling.20disabled.20.60.2F.2F.40.20ignore-test.60.20tests/with/512005974) - [#t-compiler/meetings > &rust-lang#91;steering&rust-lang#93; 2025-04-11 Dealing with disabled tests](https://rust-lang.zulipchat.com/#narrow/channel/238009-t-compiler.2Fmeetings/topic/.5Bsteering.5D.202025-04-11.20Dealing.20with.20disabled.20tests/with/511717981) ### Remarks on remaining unconditionally disabled tests under `tests/` After this PR, against commit 79a272c, only **14** remaining test files are disabled through `//@ ignore-test`: <details> <summary>Remaining `//@ ignore-test` files under `tests/`</summary> ``` tests/debuginfo/drop-locations.rs 4://@ ignore-test (broken, see rust-lang#128971) tests/rustdoc/macro-document-private-duplicate.rs 1://@ ignore-test (fails spuriously, see issue rust-lang#89228) tests/rustdoc/inline_cross/assoc-const-equality.rs 3://@ ignore-test (FIXME: rust-lang#125092) tests/ui/match/issue-27021.rs 7://@ ignore-test (rust-lang#54987) tests/ui/match/issue-26996.rs 7://@ ignore-test (rust-lang#54987) tests/ui/issues/issue-49298.rs 9://@ ignore-test (rust-lang#54987) tests/ui/issues/issue-59756.rs 2://@ ignore-test (rustfix needs multiple suggestions) tests/ui/precondition-checks/write.rs 5://@ ignore-test (unimplemented) tests/ui/precondition-checks/read.rs 5://@ ignore-test (unimplemented) tests/ui/precondition-checks/write_bytes.rs 5://@ ignore-test (unimplemented) tests/ui/explicit-tail-calls/drop-order.rs 2://@ ignore-test: tail calls are not implemented in rustc_codegen_ssa yet, so this causes 🧊 tests/ui/panics/panic-short-backtrace-windows-x86_64.rs 3://@ ignore-test (rust-lang#92000) tests/ui/json/json-bom-plus-crlf-multifile-aux.rs 3://@ ignore-test Not a test.

The outstanding one is `tests/ui/json/json-bom-plus-crlf-multifile-aux.rs` which I did not want to touch in *this* PR -- that aux file has load-bearing BOM and carriage returns and byte offset matters. I think those test files that require special encoding / BOM probably are better off as `run-make` tests. See rust-lang#139968 for that aux file. ### Review advice - Best reviewed commit-by-commit. - The directive name diverged from the most voted `//@ auxiliary` because I think that's easy to confuse with `//@ aux-{crate,dir}`. r? compiler

This used to be needed for #114036 (comment), but since it's no longer, I'm opening this as a separate PR. This also fixes one ICEing UI test: (
