void analyzeFunction(MachineFunction &MF) { const Function &F = *MF.getFunction(); const TargetMachine &TM = MF.getTarget(); bool hasVarArgs = MF.getFunction()->isVarArg(); CallingConv::ID CC = F.getCallingConv(); const TargetFrameLowering *TFL = TM.getFrameLowering(); int FrameSize = TFL->getFrameSize(MF); const TargetRegisterInfo *TRI = TM.getRegisterInfo(); unsigned NumRegs = TRI->getNumRegs(); unsigned NumAllocatableRegs = TRI->getNumAllocatableRegs(); // perform analysis based on function properties ... }The code above uses the getProperties method to obtain various properties of the machine function, such as whether it has variable arguments, its calling convention, its frame size, and its register usage. It then performs analysis based on these properties. The MachineFunction class and its associated methods are part of the LLVM framework, which is a collection of modular and reusable compiler and toolchain technologies. The LLVM framework is available as an open source package library and is written primarily in C++.
