Let's grab it while it's fresh: https://github.com/rui314/mold/releases/tag/v1.5.1 FWIW, one of the reasons why I have been using Mold myself is that some kinds of linker errors are somewhat more understandable. For example if a definition for an inline is missing, instead of only saying “symbol blah undefined”, the error from Mold will *also* indicate which object file needed it -- which means one does not have to blindly try to figure out where a “#include "FooInlines.h"” is needed :-)
