class DemandedBitsWrapperPass
Declaration
class DemandedBitsWrapperPass : public FunctionPass { /* full declaration omitted */ };Description
FunctionPass class - This class is used to implement most global optimizations. Optimizations should subclass this class if they meet the following constraints: 1. Optimizations are organized globally, i.e., a function at a time 2. Optimizing a function does not cause the addition or removal of any functions in the module

Methods
¶DemandedBitsWrapperPass()
DemandedBitsWrapperPass()Declared at: llvm/include/llvm/Analysis/DemandedBits.h:92
¶void getAnalysisUsage(
llvm::AnalysisUsage& AU) const
void getAnalysisUsage(
llvm::AnalysisUsage& AU) constDescription
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.
Declared at: llvm/include/llvm/Analysis/DemandedBits.h:95
Parameters
¶llvm::DemandedBits& getDemandedBits()
llvm::DemandedBits& getDemandedBits()Declared at: llvm/include/llvm/Analysis/DemandedBits.h:100
¶void print(llvm::raw_ostream& OS,
const llvm::Module* M) const
void print(llvm::raw_ostream& OS,
const llvm::Module* M) constDescription
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.
Declared at: llvm/include/llvm/Analysis/DemandedBits.h:102
Parameters
- llvm::raw_ostream& OS
- const llvm::Module* M
¶void releaseMemory()
void releaseMemory()Description
Clean up memory in between runs
Declared at: llvm/include/llvm/Analysis/DemandedBits.h:98
¶bool runOnFunction(llvm::Function& F)
bool runOnFunction(llvm::Function& F)Description
runOnFunction - Virtual method overriden by subclasses to do the per-function processing of the pass.
