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::RegBankSelect.
Definition at line 34 of file AMDGPURegBankSelect.cpp.
References llvm::AnalysisUsage::addRequired(), and llvm::RegBankSelect::getAnalysisUsage().
◆ getPassName()
|
overridevirtual |
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::RegBankSelect.
Definition at line 30 of file AMDGPURegBankSelect.cpp.
◆ runOnMachineFunction()
|
overridevirtual |
runOnMachineFunction - This method must be overloaded to perform the desired machine code transformation or analysis.
