Member Function Documentation

appendToVector()

void llvm::DIExpression::ExprOperand::appendToVector ( SmallVectorImpl< uint64_t > & V ) const

inline

Append the elements of this operand to V.

Definition at line 3574 of file DebugInfoMetadata.h.

References get(), and getSize().

get()

const uint64_t * llvm::DIExpression::ExprOperand::get ( ) const

inline

Definition at line 3540 of file DebugInfoMetadata.h.

Referenced by appendToVector().

getArg()

uint64_t llvm::DIExpression::ExprOperand::getArg ( unsigned I ) const

inline

Get an argument to the operand.

Never returns the operand itself. The operand has to be present and I has to be less than getNumArgs().
