Member Data Documentation
◆ Candidates
| std::vector<Candidate> llvm::outliner::OutlinedFunction::Candidates |
Definition at line 167 of file MachineOutliner.h.
◆ FrameConstructionID
| unsigned llvm::outliner::OutlinedFunction::FrameConstructionID |
Target-defined identifier for constructing a frame for this function.
Definition at line 181 of file MachineOutliner.h.
Referenced by llvm::AArch64InstrInfo::buildOutlinedFrame(), and llvm::X86InstrInfo::buildOutlinedFrame().
◆ FrameOverhead
| unsigned llvm::outliner::OutlinedFunction::FrameOverhead |
Target-defined overhead of constructing a frame for this function.
Definition at line 178 of file MachineOutliner.h.
◆ MF
| MachineFunction* llvm::outliner::OutlinedFunction::MF = nullptr |
The actual outlined function created.
This is initialized after we go through and create the actual function.
Definition at line 171 of file MachineOutliner.h.
◆ SequenceSize
| unsigned llvm::outliner::OutlinedFunction::SequenceSize |
Represents the size of a sequence in bytes.
(Some instructions vary widely in size, so just counting the instructions isn't very useful.)
