for Darwin, -mdynamic-no-pic ^ would be a real-life User case.

Thanks, Alan.
I took a quick look over the weekend (out of the office last week).
So, do you think I need to split things up so that the d-mode and ds-mode insn
fragments can have different match conditions? - or is the issue that these
patterns have no reload constraints (in which case I could at least investigate
adding Y to the relevant cases)?
