Instead, InitializePredefinedMacros calls the function with the specific type (SignedShort/UnsignedShort), as getShortWidth() > getCharWidth(), but getIntWidth() == getShortWidth(). Not sure what the best way to fix that is - should I make DefineExactWidthType use TargetInfo::getIntTypeByWidth?


I'm not sure either. I think it's a good question for @rengolin.
