abi64.h (SETUP_INCOMING_VARARGS): Undefine.
* config/mips/abi64.h (SETUP_INCOMING_VARARGS): Undefine.
* config/mips/mips-protos.h (mips_setup_incoming_varargs): Declare.
(function_arg): Constify CUMULATIVE_ARGS.
(function_arg_partial_nregs, function_arg_pass_by_reference): Likewise.
* config/mips/mips.h (UNITS_PER_FPVALUE): Zero when TARGET_SOFT_FLOAT.
(UNITS_PER_DOUBLE): New macro.
(SETUP_INCOMING_VARARGS): Define. Use mips_setup_incoming_varargs.
(CUMULATIVE_ARGS): Reformat. Remove num_adjusts workaround and
last_arg_fp field. Replace arg_words and fp_arg_words with gp_regs,
fp_regs and stack_words.
(EABI_FLOAT_VARARGS_P): New macro.
* config/mips/mips.c (struct mips_arg_info): New.
(mips_arg_info): New function.
(function_arg_advance): Use it. Add adjustment instructions here
rather than in function_arg.
(function_arg): Constify CUMULATIVE_ARGS. Use mips_arg_info. Check
for VOIDmode at the beginning of the function.
(function_partial_nregs): Constify CUMULATIVE_ARGS. Use mips_arg_info.
(function_arg_pass_by_reference): Likewise.
(mips_setup_incoming_varags): New, largely based on old abi64.h code.
(mips_build_va_list): Test EABI_FLOAT_VARARGS_P.
(mips_va_start): Likewise. Use the new stack_words field of
CUMULATIVE_ARGS to set up overflow area. Reformat.
(mips_va_arg): Test EABI_FLOAT_VARARGS_P. Unify EABI handling of
doubles and other types, aligning the overflow pointer for non-doubles
too. Remove some code duplication. Replace hard-coded constants.
