real.c (encode_ieee_extended): Initialize whole array.
* real.c (encode_ieee_extended): Initialize whole array. * reg-stack.c (move_for_stack_reg0: Use always XFmode. * i386-modes.def: Change definitions of TFmode and XFmode. * i386.c (classify_argument): Rename TFmodes to XFmodes; add new TFmode code. (construct_container): Allow constructing of TFmode integer containers. (ix86_return_in_memory): XFmode is not returned in memory. (init_ext_80387_constants): Always use XFmode. (print_operand): Likewise. (ix86_prepare_fp_compare_regs): Likewise. (split_to_parts): Deal with TFmode. (split_long_move): Simplify. (ix86_init_mmx_sse_builtins): Add __float80, __float128. (ix86_memory_move_cost): Do not confuse TFmode. * i386.h (LONG_DOUBLE_TYPE_SIZE): Set to 96. (IS_STACK_MODE): TFmode is not stack mode. (HARD_REGNO_NREGS, CLASS_MAX_NREGS): Deal nicely with XFmode. (VALID_SSE_REG_MODE): Allow TFmode. (VALID_FP_MODE_P): Disallow TFmode. (VALID_INT_MODE_P): Allow TFmode in 64bit mode. * i386.md (TFmode patterns): Kill. (movtf, motf_rex64): New patterns.
