running "opt -basicaa -gvn -S null-aliases-nothing.ll" should produce this output, what are you seeing?

; ModuleID = 'null-aliases-nothing.ll'

%t = type { i32 }

declare void @test1f(i8*)

define void @test1(%t* noalias %stuff) {
  %p = getelementptr inbounds %t* %stuff, i32 0, i32 0
  %before = load i32* %p
  call void @test1f(i8* null)
  %sum = add i32 %before, %before
  store i32 %sum, i32* %p
  ret void
}
