How are frame pointer registers that span more than one hard register handled? Would it be appropriate to check the mode and do a multiple_reg_loc_descriptor call or something similar to handle this case?
There is no requirement that the DWARF registers map one-to-one to hardware registers. You could define a DWARF register which represents the FP register, spanning two hardware registers. -- Michael Eager ea...@eagercon.com 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077
