re PR other/25028 (TImode-to-floating conversions broken)
PR other/25028
* libgcc2.h (SF_SIZE, DF_SIZE, XF_SIZE, TF_SIZE): Define.
* libgcc2.c (__floatdixf, __floatundixf, __floatditf,
__floatunditf): Use #error if type sizes don't match requirements
of implementation.
(__floatdisf, __floatdidf): Unify. Possibly use XFmode or TFmode
as wider floating-point type. Use #error if type sizes don't
match requirements of implementation. Avoid overflow in computing
Wtype_MAXp1_F * Wtype_MAXp1_F. When special casing conversion,
shift one more bit. Cast 1 to DWtype or UDWtype for shifting.
(__floatundisf, __floatundidf): Likewise.
* config/ia64/hpux.h (XF_SIZE, TF_SIZE): Define.
* config/ia64/ia64.c (ia64_init_libfuncs): Use
_U_Qfcnvfxt_quad_to_quad and _U_Qfcnvxf_quad_to_quad for
TFmode-TImode conversions.
* doc/tm.texi (SF_SIZE, DF_SIZE, XF_SIZE, TF_SIZE): Document.
testsuite:
* gcc.dg/torture/fp-int-convert-timode.c: Only XFAIL for LP64 IA64
HP-UX.
