re PR middle-end/19920 (build broken on several targets due to recent 'DC' type update to libgcc2)
PR 19920
* libgcc2.c (WORD_SIZE): Remove all definitions; replace uses
with W_TYPE_SIZE.
(HIGH_WORD_COEFF, HIGH_HALFWORD_COEFF): Remove all definitions;
replace uses with Wtype_MAXp1_F.
(L_fixunstfdi, L_fixtfdi, L_floatditf, L_fixunsxfdi, L_fixxfdi,
L_floatdixf, L_fixunsxfsi, L_fixunsdfdi, L_floatdidf, L_fixunsdfsi,
L_powidf2, L_powixf2, L_powitf2, L_muldc3, L_divdc3, L_mulxc3,
L_divxc3, L_multc3, L_divtc3): Protect with HAVE_DFMODE, HAVE_XFMODE,
and HAVE_TFMODE as appropriate.
(__fixunssfDI): Provide an implementation that doesn't need DFmode.
(__floatdisf): Likewise.
* libgcc2.h (LIBGCC2_DOUBLE_TYPE_SIZE): New.
(HAVE_DFMODE, HAVE_XFMODE, HAVE_TFMODE): New.
(Wtype_MAXp1_F): New.
(DFtype, DCtype, __fixdfdi, __floatdidf, __fixunsdfSI, __fixunsdfDI,
__powidf2, __divdc3, __muldc3): Protect with HAVE_DFMODE.
