(parm_in_stack_slot_p): ... this. Disregard mode, what matters is whether the parm will live in a pseudo or a stack slot. (expand_one_ssa_partition): Deal with params without a default def. Disregard mode. * cfgexpand.h: Renamed function declaration. * tree-ssa-coalesce.c: Adjust. * function.c (split_complex_args): Allocate stack slot for unassigned parms before splitting. (parm_in_unassigned_mem_p): New. Use it instead of parm_maybe_byref_p throughout this file. (assign_parm_setup_block): Use it. Accept pseudos in the expand-assigned rtl. (assign_parm_setup_reg): Drop BLKmode requirement. (assign_parm_setup_stack): Allocate and fill in the address of unassigned MEM parms.
