# Bug 41973. Make sure %12 is detected as live out of %bb.0, even
|
||
|
|
# though the use is allocated before the def block %bb.3. Previously
|
||
|
|
# mayLiveOut only recorded on defs, and would not find the virtual
|
||
|
|
# register use if it had already been replaced with a physical
|
||
|
|
# register.
