* | The Indexes Patch. | Lang Hames | 2009-11-03 | 1 | -0/+231 |
This introduces a new pass, SlotIndexes, which is responsible for numbering instructions for register allocation (and other clients). SlotIndexes numbering is designed to match the existing scheme, so this patch should not cause any changes in the generated code. For consistency, and to avoid naming confusion, LiveIndex has been renamed SlotIndex. The processImplicitDefs method of the LiveIntervals analysis has been moved into its own pass so that it can be run prior to SlotIndexes. This was necessary to match the existing numbering scheme. llvm-svn: 85979 |
