getOperandUseInternal()

virtual Use llvm::sandboxir::User::getOperandUseInternal ( unsigned OpIdx, bool Verify ) const

protectedpure virtual

\Returns the Use for the OpIdx'th operand.

This is virtual to allow instructions to deviate from the LLVM IR operands, which is a requirement for sandboxir Instructions that consist of more than one LLVM Instruction.

Implemented in llvm::sandboxir::Constant, and llvm::sandboxir::GlobalObject.
