Author: jsm28 Date: Thu Dec 15 21:50:10 2005 New Revision: 108598 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=108598 Log: 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.
