...ay be interested in different aspects of the returned value: register allocator may care about the spill size while optimizations tracking the predicate values will be interested in the actual size of the register. Moreover, if a register for which these two values differ had subregisters, the SubRegCoveredBits information could not be assumed to match the return value of getSize. *** Proposal Replace the getSize function in MCRegisterClass and TargetRegisterClass with two functions: getRegSize and getSpillSize. TableGen would need to be modified to generate both of them, and unless the user speci...
