Member Function Documentation

◆ getAnalysisUsage()

void StackSafetyGlobalInfoWrapperPass::getAnalysisUsage ( AnalysisUsage & ) const

overridevirtual

getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.

If a pass specifies that it uses a particular analysis result to this function, it can then use the getAnalysis<AnalysisType>() function, below.

Reimplemented from llvm::Pass.

◆ getResult()

const StackSafetyGlobalInfo& llvm::StackSafetyGlobalInfoWrapperPass::getResult ( ) const

◆ print()

void StackSafetyGlobalInfoWrapperPass::print	(	raw_ostream &	OS,
		const Module *	M
	)		const

overridevirtual

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.
