[llvm-dev] [RFC] Adding time-trace to LLD?

Hi all,

I've been using -ftime-trace on the compiler and find it very useful for
analysing compile times and whole build times. I've made a first attempt at
adding this to LLD (ELF) so link times can be traced in the same way:

This works for LTO and ThinLTO, but needs some more work to make sure it
scales well across multiple threads.

Please let me know whether you think this is worth pursuing?
