When two local symbols (think: file-scope static functions, or functions in unnamed namespaces) with the same name in two different translation units both needed thunks, ld64.lld previously created external thunks for both of them. These thunks ended up with the same name, leading to a duplicate symbol error for the thunk symbols. Instead, give thunks for local symbols local visibility. (Hitting this requires a jump to a local symbol from over 128 MiB away. It's unlikely that a single .o file is 128 MiB large, but with ICF you can end up with a situation where the local symbol is ICF'd with a symbol in a separate translation unit. And that can introduce a large enough jump to require a thunk.) Fixes PR54599. Differential Revision: https://reviews.llvm.org/D122624 |

Benchmarking
In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
