Jakob Stoklund Olesen 026dc223ae Compute lists of sub-regs, super-regs, and overlapping regs. ... Besides moving structural computations to CodeGenRegisters.cpp, this also well-defines the order of these lists: - Sub-register lists come from a pre-order traversal of the graph defined by the SubRegs lists in the .td files. - Super-register lists are topologically ordered so no register comes before any of its sub-registers. When the sub-register graph is not a tree, independent super-registers appear in numerical order. - Lists of overlapping registers are ordered according to register number. This reverses the order of the super-regs lists, but nobody was depending on that. The previous order of the overlaps lists was odd, and it may have depended on the precise behavior of std::stable_sort. The old computations are still there, but will be removed shortly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132881 91177308-0d34-0410-b5e6-96231b3b80d8		2011-06-12 03:05:52 +00:00
