; Test that the --stack-first option places the stack at the start of linear
; memory. In this case the --stack-first option is being passed along with a
; stack size of 512. This means (since the stack grows down) the stack pointer
; global should be initialized to 512.
; Also test that __heap_base is still aligned with the --stack-first option.
