--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The odd thing is that 'g' has a DECL_RESULT of void type but the function type
of 'g' has a return type of integer(kind=4) ...

ipa-split does
if (split_point->split_part_set_retval
&& !VOID_TYPE_P (TREE_TYPE (TREE_TYPE (current_function_decl))))
{
retval = DECL_RESULT (current_function_decl);
/* We use temporary register to hold value when aggregate_value_p
is false. Similarly for DECL_BY_REFERENCE we must avoid extra
copy. */
if (!aggregate_value_p (retval, TREE_TYPE
(current_function_decl))
&& !DECL_BY_REFERENCE (retval))
retval = create_tmp_reg (TREE_TYPE (retval));
interestingly when fixing the bogus call g(1, *99) then the return type
of the function is void as expected.
