◆ SelectInlineAsmMemoryOperand()

inlinevirtual |
SelectInlineAsmMemoryOperand - Select the specified address as a target addressing mode, according to the specified constraint.
If this does not match or is not implemented, return true. The resultant operands (which will appear in the machine instruction) should be added to the OutOps vector.
Reimplemented in llvm::HexagonDAGToDAGISel, llvm::LoongArchDAGToDAGISel, llvm::NVPTXDAGToDAGISel, and llvm::RISCVDAGToDAGISel.
