re PR fortran/22146 (ICE when calling ELEMENTAL subroutines)

2006-01-07  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/22146
	* trans-array.c (gfc_reverse_ss): Remove static attribute.
	(gfc_walk_elemental_function_args): Replace gfc_expr * argument for
	the function call with the corresponding gfc_actual_arglist*.  Change
	code accordingly.
	(gfc_walk_function_expr): Call to gfc_walk_elemental_function_args
	now requires the actual argument list instead of the expression for
	the function call.
	* trans-array.h: Modify the prototype for gfc_walk_elemental_function_args
	and provide a prototype for gfc_reverse_ss.
	* trans-stmt.h (gfc_trans_call): Add the scalarization code for the case
	where an elemental subroutine has array valued actual arguments.

	PR fortran/25029
	PR fortran/21256
	PR fortran/20868
	PR fortran/20870
	* resolve.c (check_assumed_size_reference): New function to check for upper
	bound in assumed size array references.
	(resolve_assumed_size_actual): New function to do a very restricted scan
	of actual argument expressions of those procedures for which incomplete
	assumed size array references are not allowed.
	(resolve_function, resolve_call): Switch off assumed size checking of
	actual arguments, except for elemental procedures and intrinsic
	inquiry functions, in some circumstances.
	(resolve_variable): Call check_assumed_size_reference.
