◆ getOperandUse()

\Returns the operand edge for OpIdx.

NOTE: This should also work for OpIdx == getNumOperands(), which is used for op_end().

Definition at line 460 of file SandboxIR.h.

◆ getOperandUseDefault()

Use User::getOperandUseDefault ( unsigned  OpIdx,
bool  Verify 
) const
protected

\Returns the Use edge that corresponds to OpIdx.

Note: This is the default implementation that works for instructions that match the underlying LLVM instruction. All others should use a different implementation.

Definition at line 220 of file SandboxIR.cpp.

References assert(), llvm::sandboxir::Value::Ctx, getNumOperands(), llvm::sandboxir::Value::Use, llvm::sandboxir::Value::Val, and Verify.

◆ 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.

Referenced by getOperandUse(), op_begin(), op_end(), llvm::sandboxir::OperandUseIterator::operator+(), llvm::sandboxir::OperandUseIterator::operator++(), and llvm::sandboxir::OperandUseIterator::operator-().

The default implementation works only for single-LLVMIR-instruction Users and only if they match exactly the LLVM instruction.
