NodeType

enum llvm::X86ISD::NodeType : unsigned

Enumerator
POP_FROM_X87_REG	The same as ISD::CopyFromReg except that this node makes it explicit that it may lower to an x87 FPU stack pop. Optimizations should be more cautious when handling this node than a normal CopyFromReg to avoid removing a required FPU stack pop. A key requirement is optimizations should not optimize any users of a chain that contains a POP_FROM_X87_REG to use a chain from a point earlier than the POP_FROM_X87_REG (which may remove a required FPU stack pop).
GlobalBaseReg	On Darwin, this node represents the result of the popl at function entry, used for PIC code.
