llvm::EdgeBundlesWrapperLegacy

Name

Description

MachineFunctionPass

MachineFunctionPass ‐ This class adapts the FunctionPass interface to allow convenient creation of passes that operate on the MachineFunction representation. Instead of overriding runOnFunction, subclasses override runOnMachineFunction.

Name

Description

EdgeBundlesWrapperLegacy [constructor]

Default constructor

operator= [deleted]

Copy assignment operator

assignPassManager

Each pass is responsible for assigning a pass manager to itself. PMS is the stack of available pass manager.

createPrinterPass [virtual]

createPrinterPass ‐ Get a function printer pass.

doFinalization [virtual]

doFinalization ‐ Virtual method overriden by subclasses to do any necessary clean up after all passes have run.

doInitialization [virtual]

dump

dumpPassStructure [virtual]

getAnalysis

getAnalysis<AnalysisType>() ‐ This function is used by subclasses to get to the analysis information that they claim to use by overriding the getAnalysisUsage function.

getAnalysisID

getAnalysisIfAvailable

getAnalysisIfAvailable<AnalysisType>() ‐ Subclasses use this function to get analysis information that might be around, for example to update it. This is different than getAnalysis in that it can fail (if the analysis results haven't been computed), so should only be used if you can handle the case when the analysis is not available. This method is often used by transformation APIs to update analysis results for a pass automatically as the transform is performed.

getAnalysisUsage [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.

getAsImmutablePass [virtual]

getAsPMDataManager [virtual]

getEdgeBundles

getPassArgument

Return a nice clean name for a pass corresponding to that used to enable the pass in opt.

getPassID

getPassID ‐ Return the PassID number that corresponds to this pass.

getPassKind

getPassName [virtual]

getPassName ‐ Return a nice clean name for a pass. This usually implemented in terms of the name that is registered by one of the Registration templates, but can be overloaded directly.

getPotentialPassManagerType [virtual]

Return what kind of Pass Manager can manage this pass.

getResolver

mustPreserveAnalysisID

mustPreserveAnalysisID ‐ This method serves the same function as getAnalysisIfAvailable, but works if you just have an AnalysisID. This obviously cannot give you a properly typed instance of the class if you don't have the class name available (use getAnalysisIfAvailable if you do), but it can tell you if you need to preserve the pass at least.

preparePassManager [virtual]

Check if available pass managers are suitable for this pass or not.

print [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.

printIRUnit [virtual]

For ‐‐print‐changed, serialize the IR unit this pass operates on. The default prints F; MachineFunctionPass prints its MachineFunction. Returns false if there is nothing to report.

releaseMemory [virtual]

releaseMemory() ‐ This member can be implemented by a pass if it wants to be able to release its memory when it is no longer needed. The default behavior of passes is to hold onto memory for the entire duration of their lifetime (which is the entire compile time). For pipelined passes, this is not a big deal because that memory gets recycled every time the pass is invoked on another program unit. For IP passes, it is more important to free memory when it is unused.

runOnFunction [virtual]

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

setResolver

verifyAnalysis [virtual]

verifyAnalysis() ‐ This member can be implemented by a analysis pass to check state of analysis information.

Description

getAnalysisUsage [virtual]

getAnalysisUsage ‐ Subclasses that override getAnalysisUsage must call this.

getClearedProperties [virtual]

getRequiredProperties [virtual]

getSetProperties [virtual]

runOnMachineFunction [virtual]

runOnMachineFunction ‐ This method must be overloaded to perform the desired machine code transformation or analysis.

skipFunction

Optional passes call this function to check whether the pass should be skipped. This is the case when Attribute::OptimizeNone is set or when optimization bisect is over the limit.

Name

Description

getPassTimer

Request the timer for this legacy‐pass‐manager's pass instance.

isBitcodeWriterPass

Check whether a pass is a BitcodeWriterPass.

isIRPrintingPass

Return true if a pass is for IR printing.
