Jakob Stoklund Olesen 31867660cb Add a CoveredBySubRegs property to Register descriptions. ... When set, this bit indicates that a register is completely defined by the value of its sub-registers. Use the CoveredBySubRegs property to infer which super-registers are call-preserved given a list of callee-saved registers. For example, the ARM registers D8-D15 are callee-saved. This now automatically implies that Q4-Q7 are call-preserved. Conversely, Win64 callees save XMM6-XMM15, but the corresponding YMM6-YMM15 registers are not call-preserved because they are not fully defined by their sub-registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148363 91177308-0d34-0410-b5e6-96231b3b80d8		2012-01-18 00:16:39 +00:00
