Hi GCC and LLVM developers, I am learning Register Allocation algorithms and I am clear that: * Unlimited VirtReg (pseudo) -> limited or fixed or alias[1] PhysReg (hard) * Memory (20 - 100 cycles) is expensive than Register (1 cycle), but it has to spill code when PhysReg is unavailable * Folding spill code into instructions, handling register coallescing, splitting live ranges, doing
