Log message:
	2005-08-19  Dave Brolley  <brolley@redhat.com>
	
	* cgen-fpu.cxx: New file.
	* cgen-fpu.h: New file.

	* Makefile.in: Regenerated.
	* Contribute the following enhancements to floating point
	support:
	
	2005-06-14  Dave Brolley  <brolley@redhat.com>
	
	* fp.h (do_round,do_normal_round,do_normal_underflow,do_normal_overflow)
	:
	Now virtual.
	* fp.cxx (do_normal_overflow): Round up to infinity only if
	the result is positive.
	(operator-): Don't apply 'neg' to a nan.
	(neg): Return src if it is a qnan.
	
	2005-05-20  Dave Brolley  <brolley@redhat.com>
	
	* fp.cxx (pack_any): Ensure that nan results have a positive sign.
	(operator-): Simply call operator+ with the rhs negated.
	* fp.h (is_negative): New method of fp.
	
	2005-05-13  Dave Brolley  <brolley@redhat.com>
	
	* fp.h (fp): All arithmetic operator methods are now members
	of class fp.
	* fp.cxx (fp): Likewise.
	
	2005-04-27  Dave Brolley  <brolley@redhat.com>
	
	* fp.cxx (fp::unpack): Only perform sanity check for non-nans.
	
	2005-04-12  Dave Brolley  <brolley@redhat.com>
	
	* fp.h: Move static constants and functions to top of file for
	visibility within the file.
	(get_status): New method of fp.
	(get_class): Likewise.
	(qnan_fraction): Likewise.
	(snan_fraction): Likewise.
	(qnan_exponent): Likewise.
	(snan_exponent): Likewise.
	* fp.cxx (fp_to_int): throw fp::overflow for overflow.
	(pack_any): Use [sq]nan_{exponent,fraction} to construct nans.
	(unpack): Initialize status to 'ok'. Set class and status using
	is_qnan_fraction and is_qnan respectively.
	
	2005-03-18  Dave Brolley  <brolley@redhat.com>
	
	* fp.cxx: Move static items from here.
