Support TI mode and soft float on PA64 This change implements TI mode on PA64. Various new patterns are added to pa.md. The libgcc build needed modification to build both DI and TI routines. We also need various softfp routines to convert to and from TImode. I added full softfp for the -msoft-float option. At the moment, this doesn't completely eliminate all use of the floating-point co-processor. For this, libgcc needs to be built with -msoft-mult. The floating-point exception support also needs a soft option. 2021-11-05 John David Anglin <danglin@gcc.gnu.org> PR libgomp/96661 gcc/ChangeLog: * config/pa/pa-modes.def: Add OImode integer type. * config/pa/pa.c (pa_scalar_mode_supported_p): Allow TImode for TARGET_64BIT. * config/pa/pa.h (MIN_UNITS_PER_WORD) Define to MIN_UNITS_PER_WORD to UNITS_PER_WORD if IN_LIBGCC2. * config/pa/pa.md (addti3, addvti3, subti3, subvti3, negti2, negvti2, ashlti3, shrpd_internal): New patterns.
