   FUNDECL is a C variable whose value is a tree node that describes the

   describes the declaration of the function.  From this it is possible to
   obtain the DECL_ATTRIBUTES of the function.

   FUNTYPE is a C variable whose value is a tree node that describes the
   function in question.  Normally it is a node of type `FUNCTION_TYPE' that
   describes the data type of the function.  From this it is possible to obtain
   the data types of the value and arguments (if known).

   When a call to a library function is being considered, FUNTYPE will contain
   an identifier node for the library function.  Thus, if you need to
   distinguish among various library functions, you can do so by their names.

   this macro is STACK-SIZE.  On the 68000, using the standard calling
   convention, no functions pop their arguments, so the value of the macro is
   always 0 in this case.  But an alternative calling convention is available
   in which functions that take a fixed number of arguments pop them but other
   functions (such as `printf') pop nothing (the caller pops all).  When this

/* A C expression that defines the machine-dependent operand constraint letters
   (`G', `H') that specify particular ranges of `const_double' values.

   If C is one of those letters, the expression should check that VALUE, an RTX
   of code `const_double', is in the appropriate range and return 1 if so, 0
   otherwise.  If C is not one of those letters, the value should be 0
   regardless of VALUE.

   `const_double' is used for all floating-point constants and for `DImode'
   fixed-point constants.  A given letter can accept either or both kinds of
   values.  It can use `GET_MODE' to distinguish between these kinds.  */

/* A C expression that places additional restrictions on the register class to
   use when it is necessary to copy value X into a register in class CLASS.
   The value is a register class; perhaps CLASS, or perhaps another, smaller
   class.  On many machines, the following definition is safe:

        #define PREFERRED_RELOAD_CLASS(X,CLASS) CLASS

   Sometimes returning a more restrictive class makes better code.  For
   example, on the 68000, when X is an integer constant that is in range for a
   `moveq' instruction, the value of this macro is always `DATA_REGS' as long
   as CLASS includes the data registers.  Requiring a data register guarantees
   that a `moveq' will be used.

   If X is a `const_double', by returning `NO_REGS' you can force X into a
   memory constant.  This is useful on certain machines where immediate
   floating values cannot be loaded into certain kinds of registers.  */

   This is closely related to the macro `HARD_REGNO_NREGS'.  In fact, the value
   of the macro `CLASS_MAX_NREGS (CLASS, MODE)' should be the maximum value of
   `HARD_REGNO_NREGS (REGNO, MODE)' for all REGNO values in the class CLASS.

   This macro helps control the handling of multiple-word values in
   the reload pass.  */
