parameter type info, set that from parameter symbols. * c-typeprint.c (c_type_print_varspec_suffix): For TYPE_CODE_FUNC, print parameter types, if available. * ch-typeprint.c (chill_type_print_base): Likewise. * gdbtypes.h (struct type): Remove function type field. (TYPE_FUNCTION_TYPE): Remove macro. We can't as simply re-use function types now that we're also storing parameter types. And the payoff is much less. * gdbtypes.c (make_function_type): Don't use/set TYPE_FUNCTION_TYPE. (recursive_dump_type): Don't print TYPE_FUNCTION_TYPE. * dwarfread.c (read_subroutine_type): Don't set TYPE_FUNCTION_TYPE.

define fundamental types.

such types, using defaults reasonable for the current language and

the current target machine.

NOTE: This routine is obsolescent. Each debugging format reader

should manage it's own fundamental types, either creating them from

suitable defaults or reading them from the debugging information,

whichever is appropriate. The DWARF reader has already been

fixed to do this. Once the other readers are fixed, this routine

will go away. Also note that fundamental types should be managed

on a compilation unit basis in a multi-language environment, not

on a linkage unit basis as is done here. */
