It's mostly in the platform ABI documents since each architecture has
different thresholds where the benefits appear, depending on what
instructions are available. LLVM just exposes an enum of the common
ones, interpreted by each backend as it wants.

Not really. The historical solution to that problem was separating
"near" and "far" pointers, I think, which LLVM doesn't support as far
as I know. It might be implementable in terms of addressspaces in
LLVM, though the targets don't at the moment.

Other than that, compiling PIC and getting a GOT entry might work,
depending on what your situation is.

Cheers.
