AFAIK, that's predicated on the functions having their own section (i.e., -ffunction-section) which I'm not sure every target uses as default.

Also, while looking for more people to add as reviewers I found this: https://github.com/llvm/llvm-project/commit/7ee46ed992690294cfe984366370cb4787fcf0f3 Which seems to have been reverted at some point, perhaps of interest
