IVUsersWrapperPass::IVUsersWrapperPass ( )

◆ getAnalysisUsage()

void IVUsersWrapperPass::getAnalysisUsage ( AnalysisUsage & ) const overridevirtual

◆ getIU() [1/2]

IVUsers & llvm::IVUsersWrapperPass::getIU ( ) inline

◆ getIU() [2/2]

const IVUsers & llvm::IVUsersWrapperPass::getIU ( ) const inline

◆ print()

print - Print out the internal state of the pass.

This is called by Analyze to print out the contents of an analysis. Otherwise it is not necessary to implement this method. Beware that the module pointer MAY be null. This automatically forwards to a virtual function that does not provide the Module* in case the analysis doesn't need it it can just be ignored.

Reimplemented from llvm::Pass.

◆ releaseMemory()

void IVUsersWrapperPass::releaseMemory ( ) overridevirtual

releaseMemory() - This member can be implemented by a pass if it wants to be able to release its memory when it is no longer needed.

The default behavior of passes is to hold onto memory for the entire duration of their lifetime (which is the entire compile time). For pipelined passes, this is not a big deal because that memory gets recycled every time the pass is invoked on another program unit. For IP passes, it is more important to free memory when it is unused.

Optionally implement this function to release pass memory when it is no longer used.
