> 2.8%. Somehow clang-fsds got 2.39% faster.

That speedup is interesting. I don't have a good theory to explain it though.

Even if this patch is somewhat performance-neutral, we still should avoid extra memory allocation if we can. Let's try ignoring synthetic sections in ICF. That's I think better.
