This patchset is a step towards having subregister liveness in the<br>
LiveIntervall class. It factors out some functionality of the LiveInterval<br>
class into a new LiveRanges class to enable reusage. As a proof of concept<br>
the final patch rewrite the Register Unit liveness tracking to use this new<br>
class and thereby avoid having unnecessary register number and spill weight<br>
fields there.<br>
<br>
Matthias Braun (5):<br>
refactor LiveInterval: introduce new LiveRanges class<br>
Pass LiveQueryResult by value<br>
change MachineVerifier to work on LiveRanges + LiveInterval<br>
work on LiveRanges instead of LiveInterval where possible<br>
Represent RegUnit liveness with LiveRanges instances<br>
