	it to split the floating point value into a long integer, and

	Also copy structure_value_addr in that case.
	Push the stack around an inline function if it makes calls
	and there are outgoing arguments on the stack which must be preserved.

        (dwarfout_file_scope_decl):  Check input node to see if it is an

	* cp-typeck.c (build_function_call_real): Merge in a change made to
	the C front end into the C++ front end to handle volatile functions.

	Thu Apr  9 03:45:03 1992  Mark Eichin  (eichin at cygnus.com)

	* cp-class.c (finish_struct): sanity check before calling popclass.
	If we're already hosed due to previous parse errors (specifically,
	we're not inside a class anymore) just report an error rather than
	crashing in popclass (if there wasn't a previous parse error, as the
	message suggests, we should get reports; this closes gcc/p0000525.)

	Wed Apr  8 08:56:49 1992  Mike Stump  (mrs@rtl.cygnus.com)

	* cp-decl.c (grokdeclarator): Fix an eichin bug introduced seconds
	ago.  Shame, he didn't put:

	Workaround for p869:
        1) grokdeclarator (around cp-decl.c:7462) is using popclass(1)
        uses popclass(1) to close the pushclass(3) done by
        build_push_scope; however, it's coming around another time and
        popping all the way out, which leads to the core dump when
        do_friend is called from global scope (do_friend uses
        current_class_name to figure out whose friendship it is
        bestowing.) Current workaround: if (friendp) don't allow
        popping all the way out. We still need to figure out how to
        make sure it only gets called the *right* time; we also need
        to figure out if the correct scope is being used, but that's a
        matter of regression testing.

	into a ChangeLog entry.

	Wed Apr  8 01:10:44 1992  Mike Stump  (mrs@rtl.cygnus.com)

	not CONSTANT_ADDRESS_P instead of call_memory_operand in the
	define_expand body to test whether the function address needs to be
	forced to a register.

	* decrose.h (HALF_PIC_DEBUG): Define as true if -mdebugb, to debug
	the half-pic code, just like debugging normal addressing.
	(CPP_SPEC): Use the __<name>__ form of the language macros instead
	of __<name>.
	(LINK_SPEC): If -pic-lib and not -noshrlib, pass -warn_nopic.
	(LIB_SPEC): Don't pass -L/usr/ccs/lib.

	* x-decrose (CCLIBFLAGS): Pass -pic-extern when building libgcc1.a.

	(pushdecl): use set_identifier_type_value so that the local value
	actually gets erased when we leave this level. Changed code that
	checks for global_binding_level to recognize that if
	class_binding_level is set, we're not in the global one.
	(poplevel_class): restore shadowed list too, like poplevel does.
	(print_binding_level): added no_print_functions and
	no_print_builtins variables to eliminate clutter while trying to
