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.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
