Field Documentation

struct args_size locate_and_pad_arg_data::alignment_pad

     The amount that the stack pointer needs to be adjusted to
     force alignment for the next argument.  

unsigned int locate_and_pad_arg_data::boundary

     slot_offset is at least this aligned.  

struct args_size locate_and_pad_arg_data::offset

     Offset of this argument from beginning of stack-args.  

struct args_size locate_and_pad_arg_data::size

     Size of this argument on the stack, rounded up for any padding it
     gets.  If REG_PARM_STACK_SPACE is defined, then register parms are
     counted here, otherwise they aren't.  

Referenced by initialize_argument_information(), and mem_overlaps_already_clobbered_arg_p().

struct args_size locate_and_pad_arg_data::slot_offset

     Offset to the start of the stack slot.  Different from OFFSET
     if this arg pads downward.  

enum direction locate_and_pad_arg_data::where_pad

     Which way we should pad this arg.
