In the second version of the patch, it says:
/* We use the original pseudo for loc, so that
^^^
emit_reload_insns() knows which pseudo this
reload refers to and updates the pseudo rtx, not
its equivalent memory location, as well as the
corresponding entry in reg_last_reload_reg. */
Is this sufficiently accurate?
