FNDECL is the declaration node of the function. This is given to the
macro RETURN_POPS_ARGS to determine whether this function pops its own args.
FUNTYPE is the data type of the function. This is given to the macro
RETURN_POPS_ARGS to determine whether this function pops its own args.
We used to allow an identifier for library functions, but that doesn't
work when the return type is an aggregate type and the calling convention
says that the pointer to this aggregate is to be popped by the callee.
1992-01-17 23:48:42 +01:00
STACK_SIZE is the number of bytes of arguments on the stack,
ROUNDED_STACK_SIZE is that number rounded up to
PREFERRED_STACK_BOUNDARY; zero if the size is variable. This is
both to put into the call insn and to generate explicit popping
code if necessary.
1992-01-17 23:48:42 +01:00
STRUCT_VALUE_SIZE is the number of bytes wanted in a structure value.
It is zero if this call doesn't want a structure value.
NEXT_ARG_REG is the rtx that results from executing
FUNCTION_ARG (args_so_far, VOIDmode, void_type_node, 1)
just after all the args have had their registers assigned.
This could be whatever you like, but normally it is the first
arg-register beyond those used for args in this call,
or 0 if all the arg-registers are used in this call.
It is passed on to `gen_call' so you can put this info in the call insn.
VALREG is a hard register in which a value is returned,
or 0 if the call does not return a value.
OLD_INHIBIT_DEFER_POP is the value that `inhibit_defer_pop' had before
the args to this call were processed.
We restore `inhibit_defer_pop' to that value.
1994-06-02 13:24:33 +02:00
