| | | | | | | | | | | have been printed with the "S" modifier after the predicate. With ARM's unified syntax, they are supposed to go in the other order. We fixed this for Thumb when we switched to unified syntax but missed changing it for ARM. Apparently we don't generate these instructions often because no one noticed until now.

* Move stack slot assignments into LiveRangeEdit.Jakob Stoklund Olesen2010-10-154-10/+16
| | | | | | | | | | All registers created during splitting or spilling are assigned to the same stack slot as the parent register. When splitting or rematting, we may not spill at all. In that case the stack slot is still assigned, but it will be dead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116546 91177308-0d34-0410-b5e6-96231b3b80d8

This could cause repeated splitting when splitting a different live range would insert uses into the periphery.
