Jakob Stoklund Olesen 9fe6b84fb2 Track liveness of unallocatable, unreserved registers in machine DCE. ... Reserved registers are unpredictable, and are treated as always live by machine DCE. Allocatable registers are never reserved, and can be used for virtual registers. Unreserved, unallocatable registers can not be used for virtual registers, but otherwise behave like a normal allocatable register. Most targets only have the flag register in this set. llvm-svn: 112649		2010-08-31 21:51:05 +00:00
