        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.
