Hi, I am confused about the call to isPhyRegUsed in calculateCalleeSavedRegisters: if (Fn.getRegInfo().isPhysRegUsed(Reg)) { // If the reg is modified, save it! CSI.push_back(CalleeSavedInfo(Reg)); } It seems that isPhyRegUsed returns true if the register is read or written in the function. If this is right, why do we save a register if it is only read in the function ?? I would have expected that calculateCalleeSavedRegisters use another function which would return true only when...
