As for weather this could be checked automatically in tidy, I don't think there's any easy way to do that, as it can't be answered with any text-based search. |

FWIW I tried this previously in #110437 Realized that I never opened a follow-up to remove just the unused symbols 😞 |

Rollup merge of rust-lang#118456 - aDotInTheVoid:unused-symbols, r=WaffleLapkin rustc_span: Remove unused symbols. As noted here, there is no guarantee that all pre-interned symbols are used. https://github.com/rust-lang/rust/blob/b10cfcd65fd7f7b1ab9beb34798b2108de003452/compiler/rustc_span/src/symbol.rs#L124-L125 This was done starting with using ripgrep to search for `sym::whatever`. I removed anything that didn't show up. However this had a huge number of false positives, due to extensive macro use. Then there was a manual phase of adding back all the ones used my macros. I don't think this was worth my time to do, but it's done now . ¯\_(ツ)_/¯
