Hello LLVM Community, Sorry for delay as I was busy in final exams. I am Vivek from India. Thanks for choosing my proposal for Interprocedural Register Allocation (IPRA) in LLVM. Mehdi Amini and Hal Finkel will be mentoring me for this project. IPRA can reduce code size and runtime of programs by allocating register across the module and procedure boundaries. I have identified some old but

Yes there is also MachineRegisterInfo::UsedPhysRegMask which should be the union of all regmasks in the function. > On May 11, 2016, at 10:47 AM, Hal Finkel via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > > > From: "Matthias Braun" <matze at braunis.de> > To: "Hal Finkel" <hfinkel at anl.gov> > Cc: "vivek pandya"

Dear Mentors, Please help me to understand our plan to implement Interprocedural Register allocator by propogating register usage info. While writing this mail I am considering all previous discussion over llvm-dev and IRC. 1) A MachineFunction pass to be executed POST-RA to collect the information about the used Registers. 2) An Immutable pass which will store reg usage info collected by

Hello, I have written following code to check each register if it is used by machineFunction or not : MachineRegisterInfo *MRI = &MF.getRegInfo(); TargetRegisterInfo *TRI = (TargetRegisterInfo *)MF.getSubtarget().getRegisterInfo(); const TargetMachine &TM = MF.getTarget(); const MCRegisterInfo *MCRI = TM.getMCRegisterInfo(); DEBUG(dbgs() << "Function Name : " <<
