Detailed Description
BasicBlockPass class - This class is used to implement most local optimizations. Optimizations should subclass this class if they meet the following constraints: 1. Optimizations are local, operating on either a basic block or instruction at a time. 2. Optimizations do not modify the CFG of the contained function, or any other basic block in the function. 3. Optimizations conform to all of the constraints of FunctionPasses.

createPrinterPass - Get a basic block printer pass.
Implements llvm::Pass.

| bool BasicBlockPass::doFinalization | ( | Function & | ) | [virtual] |
doFinalization - Virtual method overriden by BasicBlockPass subclasses to do any post processing needed after all passes have run.
| bool BasicBlockPass::doInitialization | ( | Function & | ) | [virtual] |
doInitialization - Virtual method overridden by BasicBlockPass subclasses to do any necessary per-function initialization.
| PassManagerType BasicBlockPass::getPotentialPassManagerType | ( | ) | const [override, virtual] |
Return what kind of Pass Manager can manage this pass.
Reimplemented from llvm::Pass.

| virtual bool llvm::BasicBlockPass::runOnBasicBlock | ( | BasicBlock & | BB | ) | [pure virtual] |
runOnBasicBlock - Virtual method overriden by subclasses to do the per-basicblock processing of the pass.
| bool BasicBlockPass::skipOptnoneFunction | ( | const BasicBlock & | BB | ) | const [protected] |
skipOptnoneFunction - Containing function has Attribute::OptimizeNone and most transformation passes should skip it.
