Rollup merge of #136865 - jieyouxu:long-type-path-compare-mode, r=lqd
Perform deeper compiletest path normalization for `$TEST_BUILD_DIR` to account for compare-mode/debugger cases, and normalize long type file filename hashes Fixes #136510. ### Summary - Whereas previously `$TEST_BUILD_DIR` is a normalization of `/path/to/build/test/<test_suite_name>/`, we now more deeply normalize. `$TEST_BUILD_DIR` now becomes a normalization of `/path/to/build/test/<test_suite_name>/<subdirs>/$name.$revision.$compare_mode.$debugger/` to normalize away path name differences when `--compare-mode` and/or `--debugger` are specified. - We also centralize the normalization of long type name hashes cf. #136328 (comment). ### Review advice - Best reviewed commit-by-commit. - Split into 3 commits: - **Commit 1**: compiletest changes to have `$TEST_BUILD_DIR` more deeply normalize. - **Commit 2**: remove per-test hacks for long type path hash normalizations, and rebless tests *specifically* affected by that. - **Commit 3**: rebless other tests that were changed as a side-effect of deeper `$TEST_BUILD_DIR` normalizations. **Commit 2** is created via first finding tests that try to perform long type file hash normalizations on an ad hoc, per-test basis: ``` rg --no-ignore -l --no-ignore -F -e "long-type" tests/ui/**/*.rs ``` <details> <summary>Tests with ad hoc long-type hash normalizations</summary> ``` tests/ui/type_length_limit.rs tests/ui/traits/on_unimplemented_long_types.rs tests/ui/regions/issue-102374.rs tests/ui/recursion/recursion.rs tests/ui/recursion/issue-83150.rs tests/ui/recursion/issue-23122-2.rs tests/ui/methods/inherent-bound-in-probe.rs tests/ui/issues/issue-67552.rs tests/ui/issues/issue-37311-type-length-limit/issue-37311.rs tests/ui/issues/issue-20413.rs tests/ui/issues/issue-8727.rs tests/ui/infinite/infinite-instantiation.rs tests/ui/infinite/infinite-instantiation-struct-tail-ice-114484.rs tests/ui/higher-ranked/trait-bounds/hrtb-doesnt-borrow-self-1.rs tests/ui/higher-ranked/trait-bounds/hrtb-doesnt-borrow-self-2.rs tests/ui/higher-ranked/trait-bounds/hang-on-deeply-nested-dyn.rs tests/ui/error-codes/E0275.rs tests/ui/diagnostic-width/secondary-label-with-long-type.rs tests/ui/diagnostic-width/long-e0277.rs tests/ui/diagnostic-width/non-copy-type-moved.rs tests/ui/diagnostic-width/long-E0308.rs tests/ui/diagnostic-width/E0271.rs tests/ui/diagnostic-width/binop.rs ``` </details> These ad hoc normalizations were removed, and they are reblessed. r? `````@lqd`````
