* calls.c (initialize_argument_information): If an argument has no
stack space associated with it, and BLOCK_REG_PADDING is defined,
use it to decide at which end the argument should be padded.
* function.c (assign_parms): Allocate BLKmode stack slots.
* config/mips/mips-protos.h (mips_pad_arg_upward): Declare.
(mips_pad_reg_upward): Declare.
* config/mips/mips.h (PAD_VARARGS_DOWN): Use FUNCTION_ARG_PADDING.
(CUMULATIVE_ARGS): Remove num_adjusts and adjusts.
(FUNCTION_ARG_PADDING): Use mips_pad_arg_upward.
(BLOCK_REG_PADDING): Use mips_pad_reg_upward.
* config/mips/mips.c (struct mips_arg_info): Remove struct_p.
(mips_expand_call): Remove code for generating structure shifts.
(mips_arg_info): Don't set struct_p. Don't set fpr_p for non-float
types unless using the EABI.
(function_arg_advance): Don't generate shift instructions.
(function_arg): Don't return them. Don't short-circuit the
check for double structure chunks for DFmode arguments.
(mips_pad_arg_upward, mips_pad_reg_upward): New functions.
(mips_expand_prologue): Remove code to emit structure shifts.
* config/mips/irix6-libc-compat.c: Remove workarounds for buggy
structure passing (inet_ntoa, inet_lnaof, inet_netof). Update
comments to say that only structure returns are a problem.
