Comment:

 This actually made it upstream...

 https://github.com/llvm-
 mirror/llvm/commit/c7a57cdda643e397720daa35ea3b1c4b7ce42371

 However, the use of aliases in the llvm backend prevents llvm to properly
 insert the
 altEntry at the right place

 For macOS, the NCG does allow dead-stripping. For LLVM the llvm-ng backend
 allows deadstripping of mach-o files (macOS, iOS, ...)
