Detailed Description
This pass implements the localization mechanism described at the top of this file.
One specificity of the implementation is that it will materialize one and only one instance of a constant per basic block, thus enabling reuse of that constant within that block. Moreover, it only materializes constants in blocks where they are used. PHI uses are considered happening at the end of the related predecessor.

Member Function Documentation
◆ getAnalysisUsage()
|
overridevirtual |
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 47 of file Localizer.cpp.
References llvm::AnalysisUsage::addRequired(), llvm::MachineFunctionPass::getAnalysisUsage(), and llvm::getSelectionDAGFallbackAnalysisUsage().
◆ getPassName()
|
inlineoverridevirtual |
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.
Reimplemented from llvm::Pass.
Definition at line 85 of file Localizer.h.
◆ getRequiredProperties()
|
inlineoverridevirtual |
Reimplemented from llvm::MachineFunctionPass.
Definition at line 87 of file Localizer.h.
References llvm::MachineFunctionProperties::IsSSA, and llvm::MachineFunctionProperties::set().
◆ runOnMachineFunction()
|
overridevirtual |
runOnMachineFunction - This method must be overloaded to perform the desired machine code transformation or analysis.
Implements llvm::MachineFunctionPass.
