	PR target/27681

	Backport from mainline:

	2006-05-23  Richard Sandiford  <richard@codesourcery.com>

	* libgcc2.c (LIBGCC2_MAX_UNITS_PER_WORD): New macro.
	(LIBGCC2_UNITS_PER_WORD): Use LIBGCC2_MAX_UNITS_PER_WORD rather than
	MIN_UNITS_PER_WORD to set the default.  Also use it in the guard.

	2006-05-22  Richard Sandiford  <richard@codesourcery.com>

	* mklibgcc.in (lib2funcs): Remove _floatdidf from initial assignment.

	2006-05-19  Richard Sandiford  <richard@codesourcery.com>

	* libgcc2.c (MIN_UNITS_PER_WORD): Move default definition from
	libgcc2.h.
	(LIBGCC2_UNITS_PER_WORD): Provide default definition, using old
	MIN_UNITS_PER_WORD logic from libgcc2.h.  Do nothing if
	LIBGCC2_UNITS_PER_WORD > MIN_UNITS_PER_WORD.
	* libgcc2.h (MIN_UNITS_PER_WORD): Remove definition from here.
	Use LIBGCC2_UNITS_PER_WORD rather than MIN_UNITS_PER_WORD to
	determine the size of Wtype, etc.
	* mklibgcc.in (LIB2_SIDITI_CONV_FUNCS): New argument.
	(swfloatfuncs): New variable.
	(dwfloatfuncs): Likewise.
	(lib2funcs): Remove floating-point conversion functions from
	initial assignment.  Use LIB2_SIDITI_CONV_FUNCS to determine
	the set of conversion routines needed.  Allow entries to specify
	an object name, filename and word size.  Update users accordingly.
	* Makefile.in (libgcc.mk): Pass LIB2_SIDITI_CONV_FUNCS.
	* config/mips/t-mips (LIB2_SIDITI_CONV_FUNCS): Define.

	Revert:

	2006-02-08  Roger Sayle  <roger@eyesopen.com>

	PR target/22209
	* config/fixtfdi.c: New libgcc source file.
	* config/fixunstfdi.c: New source file.
	* config/floatditf.c: New source file.
	* config/floatunditf.c: New souce file.
	* config/mips/t-iris6 (LIB2FUNCS_EXTRA): Include the new source
	files above instead of config/mips/_tilib.c.
	* config/mips/t-linux64 (LIB2FUNCS_EXTRA): Likewise.
