[PATCH] D144471: [ELF] Prohibit icf=safe warning from being fatal

Tue Feb 21 10:46:09 PST 2023

MaskRay added a comment.

I don't think we want more diagnostic levels. The warning is not fatal, it's just that some users use `--fatal-warnings` to upgrade warnings to errors.
If this warning is annoying under `--fatal-warnings`, we can think of `message(...)`. But right now, it seems appropriate for the user to be aware of the problem and discard `.llvm_addrsig` by themselves.
