2008-03-04Some improvements related to the computation of heights, depths of SUnits.Roman Levenstein
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. It has a linear run-time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47884 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-03Miscellaneous clean-ups based on Evan's feedback:Bill Wendling
- Cleaned up how the prologue-epilogue inserter loops over the instructions. - Instead of restarting the processing of an instruction if we remove an implicit kill, just update the end iterator and make sure that the iterator isn't incremented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47870 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-03This is the initial check-in for adding register scavenging to PPC. (Currently,Bill Wendling
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). A significant part of this patch fixes how kill information is handled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47863 91177308-0d34-0410-b5e6-96231b3b80d8

marking both a super- and sub-register as "killed". This removes implicit uses that are marked as "killed". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47862 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-03Multiple instructions can be inserted when eliminating frame indexes. We needBill Wendling
the register scavenger to process all of those new instructions instead of just the last one inserted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47860 91177308-0d34-0410-b5e6-96231b3b80d8
