similar to: [GSoC 2016] Adding MachineModule pass to LLVM

Hello Community, I have submitted my draft proposal for this project on the summer of code web site and shared it with the community. Please take a look at it and suggest/ comment some modifications. I have already done some study on the relevant code. I will still do some more before the final submission but this is more of designing challenge please help ! Sincerely, *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 : " <<

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"
