Zack Weinberg 94134f429f Makefile.in (BUILD_RTL): Replace $(BUILD_PREFIX)insn-modes.o with min-insn-modes.o. 
* Makefile.in (BUILD_RTL): Replace $(BUILD_PREFIX)insn-modes.o
	with min-insn-modes.o.
	(STAGESTUFF): Add min-insn-modes.c.
	(genobjs): Add genmodes.o.
	(print-rtl.o, print-rtl1.o): Depend on $(TM_P_H).
	(insn-modes.o): Depend on $(TM_H) not $(GTM_H); also real.h.
	(min-insn-modes.c, min-insn-modes.o): New rules.
	(s-modes): Also generate min-insn-modes.c.
	($(BUILD_PREFIX_1)insn-modes.o): Kill.
	* genmodes.c (struct mode_data): Add format field.
	(blank_mode, validate_mode, complete_mode): Update to match.
	(make_scalar_mode): Separate into make_int_mode and make_float_mode.
	(_SCALAR_MODE): Kill.
	(FLOAT_MODE, FRACTIONAL_FLOAT_MODE): Add format argument.
	(emit_insn_modes_c_header): Adjust.
	(emit_min_insn_modes_c_header, emit_real_format_for_mode)
	(emit_min_insn_modes_c): New functions.
	(emit_insn_modes_c): Call emit_real_format_for_mode.
	(main): Add -m option to generate min-insn-modes.c.

	all uses of FLOAT_MODE.
	* real.c: Don't define real_format_for_mode here.

	* dwarfout.c: Move default definition of PRINT_REG...
	* defaults.h: ...here.
	* print-rtl.c: Include tm_p.h.
	(DEBUG_PRINT_REG, DEBUG_REGISTER_NAMES, debug_reg_names, reg_names):
	Kill.

	this entire block with #ifndef GENERATOR_FILE.
	* regclass.c: Unconditionally define reg_names.
	* config/mips/mips.h, config/rs6000/rs6000.h, config/sh/sh.h

	number of arguments to aggregate_value_p.

	* genmodes.c (RESET_FLOAT_FORMAT, reset_float_format): New.
	* machmode.def: Explain ARCH-modes.def.  Document
	RESET_FLOAT_FORMAT.  Improve commentary on various mode
	clusters.  Do not define OI, PQI, PHI, PSI, PDI, QF, HF, TQF,
	XF, or TF modes here.  Remove backward-compatibility
	definition of CC.

	* config/c4x/c4x.c (c4x_override_options): No need to mess
	with real_format_for_mode or set REAL_MODE_FORMATs.
	(c4x_immed_int_constant): Don't apply GET_MODE_CLASS to rtx
	variable.
	* config/i386/i386.c (override_options): No need to set
