* Add native support for long double data type.
* c-exp.y (%union): Change dval to typed_val_float. Use DOUBLEST to store actual data. Change types of INT and FLOAT tokens to typed_val_int and typed_val_float respectively. Create new token DOUBLE_KEYWORD to specify the string `double'. Make production for FLOAT use type determined by parse_number. Add production for "long double" data type. * (parse_number): Use sscanf to parse numbers as float, double or long double depending upon the type of typed_val_float.dval. Also allow user to specify `f' or `l' suffix to explicitly specify float or long double constants. Change typed_val to typed_val_int. * (yylex): Change typed_val to typed_val_int. Also, scan for "double" keyword. * coffread.c (decode_base_type): Add support for T_LNGDBL basic type. * configure, configure.in: Add check for long double support in the host compiler. * defs.h: Define DOUBLEST appropriatly depending on whether HAVE_LONG_DOUBLE (from autoconf) is defined. Also, fix prototypes for functions that handle this type. * expression.h (union exp_element): doubleconst is now type DOUBLEST. * m2-exp.y f-exp.y (%union): dval becomes type DOUBLEST. * findvar.c (extract_floating): Make return value be DOUBLEST. Also, add support for numbers with size of long double. * (store_floating): Arg `val' is now type DOUBLEST. Handle all floating types. * parser-defs.h parse.c (write_exp_elt_dblcst): Arg expelt is now DOUBLEST. * valarith.c (value_binop): Change temp variables v1, v2 and v to type DOUBLEST. Coerce type of result to long double if either op was of that type. * valops.c (value_arg_coerce): If argument type is bigger than double, coerce to long double. * (call_function_by_hand): If REG_STRUCT_HAS_ADDR is defined, and arg type is float and > 8 bytes, then use pointer-to-object calling conventions. * valprint.c (print_floating): Arg doub is now type DOUBLEST. Use appropriate format and precision to print out floating point values. * value.h: Fixup prototypes for value_as_double, value_from_double, and unpack_double to use DOUBLEST. * values.c (record_latest_value): Remove check for invalid floats. Allow history to store them so that people may examine them in hex if they want. * (value_as_double unpack_double): Change return value to DOUBLEST. * (value_from_double): Arg `num' is now DOUBLEST. * (using_struct_return): Use RETURN_VALUE_ON_STACK macro (target specific) to expect certain types to always be returned on the stack.
