Log message:
	* real.h: Don't define REAL_INFINITY or REAL_IS_NOT_DOUBLE.
	Always make REAL_VALUE_TYPE a struct containing an array of
	HOST_WIDE_INT, not a double.  Tidy up the code deciding how
	big it is.  Don't declare or use union real_extract.
	
	* emit-rtl.c (init_emit_once), varasm.c (immed_real_const_1,
	decode_rtx_const, output_constant_pool), config/a29k/a29k.c
	(print_operand), config/arm/arm.c (output_move_double),
	config/arm/arm.md (consttable_4, consttable_8),
	config/romp/romp.c (output_fpops), config/s390/s390.h
	(ASM_OUTPUT_SPECIAL_POOL_ENTRY), config/xtensa/xtensa.c
	(xtensa_output_literal): Don't use union real_extract.
	
	* config/dsp16xx/dsp16xx.c (print_operand), config/i860/i860.c
	(sfmode_constant_to_ulong), config/ns32k/merlin.h
	(PRINT_OPERAND), config/ns32k/ns32k.c (print_operand),
	config/pdp11/pdp11.h (PRINT_OPERAND), config/we32k/we32k.h
	(PRINT_OPERAND): Don't use local version of union
	real_extract.
	
	* config/convex/convex.c (check_float_value), config/vax/vax.c
	(vax_float_literal), config/m88k/m88k.md (divdf3),
	config/dsp16xx/dsp16xx.md (fixuns_trunchfhi2),
	config/pdp11/pdp11.c (output_move_quad): Don't do host
	arithmetic on target floating point quantities.
	
	* config/a29k/a29k.md, config/dsp16xx/dsp16xx.c
	(output_dsp16xx_float_const): Don't test HOST_FLOAT_FORMAT.
	
	* fold-const.c (fold), simplify-rtx.c (simplify_binary_real):
	Use MODE_HAS_INFINITIES rather than #ifdef REAL_INFINITY.
	
	* real.c (earith): Test INFINITY rather than REAL_INFINITY;
	NANS implies INFINITY, so can drop #ifdef NANS inside #ifndef
	INFINITY.
	* print-rtl.c (print_rtx): Disable code which needs
	floating-point emulator.
	* libgcc2.c: Include float.h and use DBL_MANT_DIG,
	FLT_MANT_DIG, to define DF_SIZE and SF_SIZE, rather than
	depending on HOST_FLOAT_FORMAT to be defined properly.
	
	* ch/grant.c, cp/error.c: Always use REAL_VALUE_TO_DECIMAL;
	don't test REAL_IS_NOT_DOUBLE.
	
	* config/1750a/1750a.c (get_double, float_label): Delete.
	(print_operand): Delete huge commented-out chunk.  Use
	REAL_VALUE_TO_DECIMAL.
	* config/1750a/1750a-protos.h: Delete prototypes of deleted
	functions.
	* config/convex/convex.h: Always set TARGET_FLOAT_FORMAT to
	IEEE_FLOAT_FORMAT.
	* config/i370/i370.h (PRINT_OPERAND [TARGET_HLASM version]):
	Use REAL_VALUE_TO_DECIMAL as ELF version does.
	* config/m88k/m88k.c (real_power_of_2_operand,
	legitimize_operand): Take the REAL_VALUE_TYPE and/or union
	real_extract out of the union; run the input through
	REAL_VALUE_TO_TARGET_DOUBLE, then plug the pair of longwords
	from that into the union.
	* config/pdp11/pdp11.c (output_move_double): Rearrange
	parentheses to make automatic indenter happy.
	
	* doc/tm.texi (Cross-compilation): Rename node to "Floating
	Point" and rewrite to describe current situation.  Also adjust
	documentation of REAL_VALUE_TO_TARGET_SINGLE and friends to
	match code.
	* doc/rtl.texi: Adjust cross reference.
