* 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.

/* read_register_bytes and write_register_bytes are generally a *BAD* idea.
They are inefficient because they need to check for partial updates, which
can only be done by scanning through all of the registers and seeing if the
bytes that are being read/written fall inside of an invalid register. [The
main reason this is necessary is that register sizes can vary, so a simple
index won't suffice.] It is far better to call read_register_gen if you
want to get at the raw register contents, as it only takes a regno as an
argument, and therefore can't do a partial register update. It would also
be good to have a write_register_gen for similar reasons.
Prior to the recent fixes to check for partial updates, both read and
write_register_bytes always checked to see if any registers were stale, and
then called target_fetch_registers (-1) to update the whole set. This
caused really slowed things down for remote targets. */
