Replacing ld with gold - any experience?

Question

Has anyone tried to use gold instead of ld?

gold promises to be much faster than ld, so it may help speeding up test cycles fo

As a Samba developer, I have been using the gold linker almost exclusively on Ubuntu, Debian, and Fedora since several years now. My assessment:

• gold is many times (felt: 5-10 times) faster than the classical linker.
• Initially, there were a few problems, but the have gone since roughly Ubuntu 12.04.
• The gold linker even found some dependency problems in our code, since it seems to be more correct than the classical one with respect to some details. See, e.g. this Samba commit.

I have not used gold selectively, but have been using symlinks or the alternatives mechanism if the distribution provides it.
