Detailed Description

Use is here to make keeping the "use" list of a Value up-to-date really easy.

Member Function Documentation

void llvm::Use::swap

(

Use &

RHS

)

swap - provide a fast substitute to std::swap<Use> that also works with less standard-compliant compilers

Definition at line 22 of file Use.cpp.

References llvm::Value::addUse(), removeFromList(), V1, and Val.

llvm::Use::operator Value *

(

)

const [inline]

Normally Use will just implicitly convert to a Value* that it holds.

Definition at line 64 of file Use.h.

Value* llvm::Use::get

(

)

const [inline]

If implicit conversion to Value* doesn't work, the get() method returns the Value*.

User * llvm::Use::getUser

(

)

const

getUser - This returns the User that contains this Use. For an instruction operand, for example, this will return the instruction.

void llvm::Use::zap	(	Use *	Start,

zap - This is used to destroy Use operands when the number of operands of a User changes.
