	gdb            : ChangeLog ada-lang.c ada-lang.h infcall.c 

Log message:
	[Ada/funcalls] do not coerce fat pointers on the stack
	
	When one of the parameter values in a subprogram calls is an array
	whose value does not come from inferior memory, the debugger first
	copies the array value in inferior memory.  Up to now, the memory
	used to hold that copy was taken from the stack (just below the SP),
	but this is causing problems on SPARC v9.
	
	So the immediate fix is to follow what C does with arrays and strings,
	which is allocate memory on the heap.
	
	gdb/ChangeLog:
	
	* ada-lang.c: #include "value.h".
	(ensure_lval): Delete advance declaration.  Remove gdbarch and sp
	arguments.  Implement using value_allocate_space_in_inferior
	instead of allocating memory from the stack.
	(make_array_descriptor): Remove gdbarch and sp parameters.  Update
	calls to ensure_lval.
	(ada_convert_actual): Remove gdbarch and sp parameters.  Update
	calls to make_array_descriptor and ensure_lval.
	* ada-lang.h (ada_convert_actual): Update declaration.
	* infcall.c (value_arg_coerce): Update call to ada_convert_actual.
