What kind of information should we make accessible in an hypothetical MachineModule? I.e., how do you plan to use the MachineModulePass so that we make the right design decisions for the

Hello, Probably this may be too late to start thinking about this project but I think this is particularly useful feature for LLVM. A quick use I can think of this is Implementing Inter-procedural Register Allocation ( for Research purpose ). I have start looking at the code for MachineFunctionPass, I think currently MachineModule class is not available ( the project work will include that ) but

I think that any information that isn't being serialized in MI right now for a function could be as well. Definitely something for GlobalISel

Hi, I would like your opinions on the contract we have between the LLVM IR and the backends. * Context * Right now, the backends are supposed to be able to perform instruction selection on any valid LLVM IR. Although this is *not* something I want to change for GlobalISel, I thought I brought that up on the mailing list to discuss the implications. In particular, in the past, some people

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 : " <<

Hi, With this email, I would like to kick-off the development for the next instruction selector that I described during the last LLVM Dev’ Meeting. For the motivations, see Jakob’s proposal (http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-August/064727.html <http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-August/064727.html>) and for the proposal, see the slides (Keynote:
