The documentation does not appear to be kept up to date in this area. If one looks at the analogous code for various recent tags: same point. For example, 19.1.1 and 20-init : https://github.com/llvm/llvm-project/blob/llvmorg-19.1.1/lld/ELF/Driver.cpp= #L1656-L1679 https://github.com/llvm/llvm-project/blob/llvmorg-20-init/lld/ELF/Driver.cp= p#L1647-L1670 They do not match: https://clang.llvm.org/docs/ThinLTO.html Comparison to llvm upstream needs to be based on the upstream code, not the out of date documentation.
