This is not very feasible, since whether or not the address is required to be offsettable depends on which alternative is selected; and the current flow of find_reloads does all the address reloading (including L_R_A) *before* even looking at the alternatives. So we currently first make all addresses valid (for the most general type of address the target supports), then select an alternative, and if that alternative requires a more strict form of address, we simply reload into a base register. This is of course somewhat inefficient, but changing it would require major rework of find_reloads. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18641
