of inf, nan, finite, isinf and isnan.
* builtin-types.def (BT_DFLOAT32, BT_DFLOAT64, BT_DFLOAT128,
BT_DFLOAT32_PTR, BT_DFLOAT64_PTR, BT_DFLOAT128_PTR,
BT_FN_DFLOAT32, BT_FN_DFLOAT64, BT_FN_DFLOAT128,

* c-decl.c (declspecs_add_type): Verify combos on type qualifiers.
Pedwarn if decimal floating point types are used. Error if
decimal floating point is not supported by the target.
(finish_declspecs): Return type from DFP typespec_word.
* c-typeck.c (c_common_type): Choose the decimal floating point
type with the greater precision when determining a common type.
(convert_arguments): Warn if there is a mismatch between argument
and prototype for decimal float types. Warn of conversions with
binary float types and of precision narrowing due to prototype.
* c-parser.c (reswords): Add _Decimal32, _Decimal64, _Decimal128.
(c_token_starts_typename): Handle RID_DFLOAT32/64/128.
(c_token_starts_declspecs): Likewise.

types if the target supports them.

(c_cpp_builtins): Register built-in __DEC_EVAL_METHOD__ define.
Call builtin_define_decimal_float_constants for each type.
* c-lex.c (interpret_float): Decode decimal float types from CPP_N
flags. Use real_from_string3, which can handle binary or decimal
floats.
* c-tree.h (enum c_typespec_keyword): Add cts_dfloat32,
cts_dfloat64, cts_dfloat128.
* tree.c (build_common_tree_nodes_2): Add decimal float types.
* tree.h (enum tree_index): Add new enumeration values
TI_DFLOAT32_TYPE, TI_DFLOAT64_TYPE, TI_DFLOAT128_TYPE,
TI_DFLOAT32_PTR_TYPE, TI_DFLOAT64_PTR_TYPE, TI_DFLOAT128_PTR_TYPE.
(dfloat32_type_node): New macro.
(dfloat64_type_node, dfloat128_type_node): Likewise.
