struct OutlinedFunction

Declaration

struct OutlinedFunction { /* full declaration omitted */ };

Declared at: llvm/include/llvm/CodeGen/MachineOutliner.h:163

Member Variables

public int Candidates

public llvm::MachineFunction* MF = nullptr

The actual outlined function created. This is initialized after we go through and create the actual function.

public unsigned int SequenceSize = 0

Represents the size of a sequence in bytes. (Some instructions vary widely in size, so just counting the instructions isn't very useful.)

public unsigned int FrameOverhead = 0

Target-defined overhead of constructing a frame for this function.

public unsigned int FrameConstructionID = 0

Target-defined identifier for constructing a frame for this function.
