Member Function Documentation

void BlockFrequencyInfo::getAnalysisUsage ( AnalysisUsage & ) const

virtual

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.

Definition at line 124 of file BlockFrequencyInfo.cpp.

References llvm::AnalysisUsage::addRequired(), and llvm::AnalysisUsage::setPreservesAll().

BlockFrequency BlockFrequencyInfo::getBlockFreq ( const BasicBlock * BB ) const

getblockFreq - Return block frequency. Return 0 if we don't have the information. Please note that initial frequency is equal to ENTRY_FREQ. It means that we should not rely on the value itself, but only on the comparison to the other block frequencies. We do this to avoid using of floating points.

void BlockFrequencyInfo::print	(	raw_ostream &	O,
		const Module *	M
	)		const

virtual

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.

bool BlockFrequencyInfo::runOnFunction ( Function & F )

virtual

runOnFunction - Virtual method overriden by subclasses to do the per-function processing of the pass.

Implements llvm::FunctionPass.

void BlockFrequencyInfo::view ( ) const

Pop up a ghostview window with the current block frequency propagation rendered using dot.
