Scalar Repl cannot currently promote this testcase to 'ret long cst':
%struct.X = type { int, int }
%struct.Y = type { %struct.X }
ulong %bar() {
%retval = alloca %struct.Y, align 8 ; <%struct.Y*> [#uses=3]
%tmp12 = getelementptr %struct.Y* %retval, int 0, uint 0, uint 0 ; <int*> [#uses=1]
store int 0, int* %tmp12
%tmp15 = getelementptr %struct.Y* %retval, int 0, uint 0, uint 1 ; <int*> [#uses=1]
store int 1, int* %tmp15
%retval = cast %struct.Y* %retval to ulong* ; <ulong*> [#uses=1]
%retval = load ulong* %retval ; <ulong> [#uses=1]
ret ulong %retval
}
it should be extended to do so.
