; The -raise pass is not correctly deleting instructions in all cases where it
|
|
; should, which leaves the instruction to be deleted by DCE. This is bad
|
|
; because some instructions are left in an invalid form, causing an assertion
|
|
; failure. In this case, a chain of instructions, including a zero argument;
|
|
; PHI node is left behind.
