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 41 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 1024. 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.

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