; entries when running globalopt and the MergeFunctions instance is still alive
|
|
; the optimization of @G would cause an assert because globalopt would do an

; causes an assert in the ValueHandle call back because we are RAUWing with a

; different type (AllocaInst) than its key type (GlobalValue).
