Extended Description

This is a sister bug to bug 1152. The optimizations that gccld performs should
be available with a single command line option such as -std-lto-passes. The
linking capability of gccld will not be moved as it is redundant with llvm-link
and llvm-ld.

crazy idea, why not replace gccld with llvm-ld?

Because that puts the optimizations in llvm-ld and makes it much larger?
However, if we did this, at least the linker part wouldn't be redundant. It also
makes sense to have LTO optimizations directly in the linker. Hmm .. okay, I
think you're right :)

The point is that llvm-link doesn't handle archives, opt doesn't link, and llvm-ld is otherwise redundant.
Replacing gccld with a combination of llvm-ld and opt is fine.

Hmm, perhaps llvm-ld should link in the LTO library and invoke its
optimizations. That way there's only one place to maintain the "standard"
link-time optimizations that we run.

gccld has been replaced with a script:

Sounds done to me.
