; There are two functions being checked here, one which is optnone and the other which isn't.
; As we are running at O2, we default to using SDAG for selection. The optnone function however,
; will make use of GlobalISel. The top check, checks that the GlobalISel pipeline is run on the 
; optnone function, and the second line is checking that SDAG was run on the normal function.
