[PATCH] D55234: Do not use a hash table to uniquify mergeable strings.

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added a comment.

I ran lld with a few more large programs, and here is the result.

  Size   Before  After  
  6.1GB  20.16s  19.15s (-4.98%)
  3.8GB  56.27s  53.38s (-5.14%)
  2.5GB  32.65s  32.56s (+0.28%)

Since large programs take time to link, and in order to reduce noise I need to run it many times, it is not easy to run lld on many large programs, but I believe you can still see a pattern. At least I think I can say that removing the hash table is not bad.
