...ressure tracking, mainly the source files 'RegisterPressure.h/cpp', 'MachineRegisterInfo.h/cpp', 'TargetRegisterInfo.h/cpp'. There is a concept I can hardly understand, the 'register pressure set'. Class 'TargetRegisterInfo' defines two virtual methods 'getRegClassPressureSets' and 'getRegUnitPressureSets' for querying but I don't see any subclasses overriding it. What's the meaning of the register pressure set? Anyone can give me some help? Thanks! Xing

...done by the strategy. The generic interface, getMaxPressureDelta(), is very clunky now. I’m going to improve it, but If you’re writing a target specific strategy, it’s probably easier to directly query a pressure set for a specific register class. e.g. RC =TRI->getRegClass(R) *PSetID = TRI->getRegClassPressureSets(RC) Now you have a raw pointer right into the machine model’s null terminated array of PSetIDs that are affected by a register class (targets often have several overlapping register classes). You can choose one of those sets to track or track them all. I’m about to commit a patch that will have th...

Hi, I'm working on defining a SchedMachineModel for the Southern Islands family of GPUs, and I have two questions related to the MachineScheduler. 1. I have a resource that can process 15 instructions at the same time. In the TableGen definitions, should I do: def HWVMEM : ProcResource<15>; or let BufferSize = 15 in { def HWVMEM : ProcResource<1>; } 2. Southern Islands has

Hello, why LLVM does not define physical register limits for MIPS by overriding the TargetRegisterInfo::getRegPressureLimit function the way it’s done for X86 in x86RegisterInfo.cpp and ARM.
