defaults.h (IBM_FLOAT_FORMAT): Macro definition removed.

2007-05-21  Andreas Krebbel  <krebbel1@de.ibm.com>

	* defaults.h (IBM_FLOAT_FORMAT): Macro definition removed.
	* doc/tm.texi (IBM_FLOAT_FORMAT): Documentation entry removed.
	* real.c (encode_i370_single, decode_i370_single,
	encode_i370_double, decode_i370_double): Functions removed.
	(i370_single_format, i370_double_format): Initializations removed.
	(real_maxval, round_for_format, exact_real_truncate, significand_size):
	Consider the log2_b field to always be one.
	(ieee_single_format, mips_single_format, coldfire_single_format,
	ieee_double_format, mips_double_format,	coldfire_double_format,
	ieee_extended_motorola_format, ieee_extended_intel_96_format,

	decimal_single_format, decimal_double_format, decimal_quad_format,
	c4x_single_format, c4x_extended_format, real_internal_format): Remove
	initialization of log2_b.
	* real.h (i370_single_format, i370_double_format): Declarations removed.
	* c-cppbuiltin.c (builtin_define_float_constants): Consider the log2_b
	field to always be one.
