Member Function Documentation

◆ drop()

void mlir::detail::IROperandBase::drop ( )
inlineprotected

Remove this use of the operand.

Definition at line 80 of file UseDefLists.h.

References back, nextUse, and removeFromCurrent().

Referenced by mlir::IROperand< DerivedT, IRValueT >::drop().

◆ getNextOperandUsingThisValue()

IROperandBase* mlir::detail::IROperandBase::getNextOperandUsingThisValue ( )
inline

Return the next operand on the use-list of the value we are referring to.
