llvm::SwitchInstProfUpdateWrapper

Synopsis

Declared in <llvm/IR/Instructions.h>

class SwitchInstProfUpdateWrapper;

A wrapper class to simplify modification of SwitchInst cases along with their prof branch_weights metadata.

Name	Description
`CaseWeightOpt`	Optional profile weight for one switch successor.

Name	Description
`SwitchInstProfUpdateWrapper` [constructor]	Construct a wrapper that keeps branch weights in sync for `SI.`
`~SwitchInstProfUpdateWrapper` [destructor]	Write updated branch weights back to the switch if needed.
`addCase`	Add case `OnVal` -> `Dest` with optional branch weight `W.`
`eraseFromParent`	Delegate eraseFromParent to the wrapped switch and skip destructor updates.
`getSuccessorWeight`	Return the profile weight of successor `idx.`
`operator*`	Return a reference to the wrapped switch instruction.
`operator->`	Return a pointer to the wrapped switch instruction.
`removeCase`	Remove case `I` and its branch weight from the wrapped switch.
`replaceDefaultDest`	Replace the default destination with the case referenced by `I.`
`setSuccessorWeight`	Set the profile weight of successor `idx.`
`operator SwitchInst*`	Convert to a pointer to the wrapped switch instruction.

Name	Description
`getSuccessorWeight`	Return the profile weight of successor `idx` in `SI.`

Name	Description
`init`	Initialize branch-weight metadata from the wrapped switch.
