Detailed Description

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

Value* llvm::Use::get ( ) const

inline

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

Use* llvm::Use::getNext ( ) const

inline

Definition at line 114 of file Use.h.

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.

Use * llvm::Use::initTags ( Use *  Start, Use *  Stop  )

static

initTags - initialize the waymarking tags on an array of Uses, so that getUser() can find the User from any of those Uses.

llvm::Use::operator Value * ( ) const

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

void llvm::Use::zap ( Use *  Start, const Use *  Stop, bool  del = false  )

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