#includeIn this example, we create a new LiveInterval object and add several segments to it. Each segment defines a range of program points during which the variable is live. This example code uses the LLVM package library, specifically the "llvm/CodeGen/LiveInterval.h" header file. LLVM is an open-source compiler infrastructure framework that provides libraries and tools for building compilers, as well as a collection of reusable compiler and code analysis components.using namespace llvm; int main() { LiveInterval LI(Reg); LI.addSegment(MachineBasicBlock::iterator(), MachineBasicBlock::iterator(), 1); LI.addSegment(MachineBasicBlock::iterator(), MachineBasicBlock::iterator(), 3); LI.addSegment(MachineBasicBlock::iterator(), MachineBasicBlock::iterator(), 5); return 0; }
