* Some improvements related to the computation of heights, depths of SUnits.Roman Levenstein2008-03-041-21/+93
| | | | | | | The basic idea is that all these algorithms are computing the longest paths from the root node or to the exit node. Therefore the existing implementation that uses and iterative and potentially exponential algorithm was changed to a well-known graph algorithm based on dynamic programming.

* This is the initial check-in for adding register scavenging to PPC. (Currently,Bill Wendling2008-03-037-108/+369
| | | | | | | | | | | PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that it uses a register other than the default R0 register (the scavenger scrounges for one).
