; When constant propogating terminator instructions, the basic block iterator
|
|
; was not updated to refer to the final position of the new terminator. This
|
|
; can be bad, f.e. because constproping a terminator can lead to the
|
|
; destruction of PHI nodes, which invalidates the iterator!
|
|
;
|
|
; Fixed by adding new arguments to ConstantFoldTerminator
|
|
;
|
|
; RUN: opt < %s -constprop
