class ModuloScheduleExpander

Declaration

class ModuloScheduleExpander { /* full declaration omitted */ };

Description

The ModuloScheduleExpander takes a ModuloSchedule and expands it in-place, rewriting the old loop and inserting prologs and epilogs as required.

Declared at: llvm/include/llvm/CodeGen/ModuloSchedule.h:153

Method Overview

• public ModuloScheduleExpander(llvm::MachineFunction & MF, llvm::ModuloSchedule & S, llvm::LiveIntervals & LIS, llvm::ModuloScheduleExpander::InstrChangesTy InstrChanges)
